Introduction to Map Composer

Introduction to Map Composer A Map Composer Viewer is a Viewer window that is tailored for creating maps, which are usually output to a hardcopy device. Select one of the topics below for more information: Starting Map Composer Map Composer vs. Viewer Map Compositions Printing a Map Composition Map Frames Map Annotation Output to Film (create a map composition that is NOT resampled in the printing process)

➲ See the ERDAS IMAGINE Tour Guides manual for step-by-step instructions on creating a map.

1

Starting Map Composer

Starting Map Composer To start Map Composer, click on this button on the IMAGINE icon panel:

The Map Composer dialog is opened, allowing you to create a new map composition or select an existing one to edit or print. By selecting File | New | Map Composition..., you can also open or create a map composition from the Viewer menu bar.

2

Map Composer vs. Viewer

Map Composer vs. Viewer The Map Composer Viewer menu is similar to the Viewer menu. A Map Composer window has many of the same features as a Viewer, plus some added features to help you compose maps. The table below summarizes the differences: Feature

Map Compositions

Map Compositions A map composition or map file is a file created with the Map Composer, usually to be output to hardcopy. It contains map frames and map annotation. In the Map Composer, map frames and a single layer of map annotation are each treated as a layer. These layers can be rearranged and deleted with the Arrange Layers dialog. Map Composition Files Map composition files have the extension .map. They can be created, edited, and viewed only in a Map Composer Viewer.

☞ Map compositions and plot files (UNIX only) created in ERDAS IMAGINE Ver.8.3 and later cannot be viewed or printed using earlier versions of ERDAS IMAGINE due to enhancements.

Printing a Map Composition Follow these steps to print a map composition: 1. To be printed, a map composition must first be saved to a file. Select File | Save | Map Composition... or Save | Map Composition As... from the Map Composer Viewer menu bar. 2. Click on the Map Composer icon from the ERDAS IMAGINE icon panel. 3. Click Print... from the Map Composer dialog. The Print Map Composition dialog is opened allowing you to select the destination printer or plotter (UNIX only) and enter other printing options. The Map Maker program then takes over. It reads the saved map composition file (.map extension) and creates a bitmap or PostScript file with the extension .panel_ n , where n is the number of the panel, starting from 0. The bitmap file is an IMAGINE file that can be viewed in the Viewer, if desired. Printing a Plot File (UNIX Only) There is a name file associated with each panel file for plotting. The name file extension is .plt.panel_n .name. A plot file (.plt extension) contains all the panel_n name files. The plot file can be printed from the Map Composer dialog. The plot files are queued for printing. The raster filter (e.g., vf_versatec or vf_kodak) is used to send the bitmap files automatically to the output device.

Map Frames

Map Frames The map frame is a frame in a Map Composer window that holds the “body” of your maps. Map frames display raster, vector, and annotation layers. A map frame is similar to an annotation element — it is drawn, selected, and resized like a rectangle. The contents of a map frame are referenced from the files that are open in a Viewer or imported encapsulated PostScript files. The data are not copied. When you create a map frame, you simply click in the Viewer that you want to reference (or specify the name of the PostScript file), and the map frame will display the data as they are stored in a file, or in some cases, as they appear in the Viewer:

♦ Raster data — changes to the file will appear in a map frame after the map composition is opened in a Map Composer or printed.

♦ Annotation — changes will appear in the map frame. You can edit annotation in a map frame, and changes will appear in a Viewer that has the same annotation displayed.

♦ Vector — behaves the same as annotation. Creating a Map Frame To create a map frame in your map composition, follow these steps: 1. Open a Viewer window and display the layer(s) that you want to appear in your map frame. 2. Create and edit annotation data in the Viewer before referencing it to a map frame. This ensures that: -- the annotation in your map frame will be georeferenced to the raster data in the Viewer, and -- the annotation created in the map frame will be clipped to the map frame. (If needed, you can edit the annotation in the Viewer or the map frame later.) 3. Save the data in the Viewer as a precaution. 4. Select Annotation | Tools... from the Map Composer Viewer (if the Annotation Tools are not already displayed). 5. From the Annotation Tools palette, select the frame.

Map Frames 6. The Create Frame Instructions display. Click in the Viewer that you want referenced by the new map frame. At this point, you have several options for determining the size of the map frame in the map composition, the area of the Viewer that is referenced, and the scale of the data. These are explained below.

Map Frame Dimensions After you draw a map frame, the Map Frame dialog is opened, giving you options for sizing, scaling, and positioning the map frame. The dimensions of a map frame are expressed in the following ways:

♦ The map area is the area in the Viewer that is displayed in the map frame in the map composition.

♦ The frame area is the area used by the map frame in the map composition. ♦ The scale (like the scale used in geometric correction) is the ratio of distance in the map frame to the distance that is represented on the ground. (If the data that are referenced from the Viewer to the map frame are not georeferenced, then the scale shown is the ratio of distance in the map frame to pixels.) While you are using the Map Frame dialog to configure a map frame for the first time, you can change any two of the above while keeping the other one constant. To specify these dimensions, you can do any of the following:

♦ Use the map area box that appears in the Viewer window. You can move, resize, and rotate it like an annotation element. (Be sure that the Maintain Map Area radio button in the Map Frame dialog is not on.)

♦ Use the frame area box that appears in the Map Composer window. You can move and resize it like an annotation element. (Be sure that the Maintain Frame Area radio button in the Map Frame dialog is not on.)

♦ Specify map area, frame area, and/or scale in the Map Frame dialog. When you resize a map area box or a frame area box, the other box resizes accordingly, so that the aspect ratio (relative width and height) for both boxes is the same.

Editing a Map Frame There is a difference between editing a map frame and editing the contents of that map frame. Since a map frame is like a mini-Viewer, you can edit the annotation inside it.

6

Map Frames

☞ If you edit a .map file by changing an absolute path to a relative path, make sure the relative path is relative to the path of composition. You will be prompted for the file name if Map Composer cannot find the file. 7. To select a map frame, click the icon on the Annotation Tools palette, and then click in the desired map frame. If one map frame completely obscures another, use the Arrange Layers dialog to bring it to the top. To position a map frame, select the map frame and then drag its bounding box to the new location. To resize a map frame, select the map frame and then drag a line on any side of its bounding box to a new location. The center point of the map frame will remain stationary, and the map frame will maintain the same aspect ratio. The scale and frame area of the map frame will change. The map area will remain constant. Using the Map Frame Dialog Box You can also edit a map frame with the Map Frame dialog. Double-click inside the map frame, click Properties in the Annotation menu, or click the Properties icon in the Annotation tool palette. The Map Frame dialog will open with the settings you originally entered to position and size the map frame. A Viewer will also open, showing the area of the data now in the map frame. A white cursor box in the Viewer indicates the area currently in the map frame. At this point, you can change the information in the Map Frame dialog, or move the cursor in the Viewer to change the data in the map frame. Click OK in the Map Frame dialog when you are satisfied with the map frame.

Editing Map Frame Contents You can do the following in a map frame just as you would in a Viewer: Edit Annotation Arrange Layers

Deleting Layers in a Map Frame To delete layers in a map frame: 1. Select View | Arrange Layers... from the Map Composer Viewer menu bar. 2. Click inside the map frame. 7

Map Frames 3. The Arrange Layers dialog is opened, showing each layer in the map frame. Use the right button menu to delete the layer, and then click Apply in the Arrange Layers dialog. The map frame will be deleted. This cannot be undone.

i

You can delete all of the layers to create an empty map frame for use in a map composition template.

Adding Layers to an Empty Map Frame To add layers to an empty map frame:

♦ Double-click inside the empty map frame, or ♦ Click on Properties in the Annotation menu or click the Properties icon in the Annotation tool palette.

Deleting a Map Frame To delete a map frame from the Map Composer: 1. Select View | Arrange Layers... from the Map Composer Viewer menu bar. 2. Click in the Map Composer outside of all map frames. 3. The Arrange Layers dialog is opened, showing each map frame in the Map Composer. Use the right button menu to delete the layer, and then click Apply in the Arrange Layers dialog. The map frame will be deleted. This cannot be undone.

Map Annotation

Map Annotation Map annotation is the annotation in a map composition. It is the annotation outside the map frame(s), such as the title of the map and other explanatory annotation. Map annotation is also any annotation that is on top of the map frame(s) but not in the map frame(s) (i.e., annotation that is not clipped to the map frame).

☞ In a map composition, if an annotation layer exists in a map frame, that is where any new annotation elements will be created and stored. The marquee selector tool used inside the map frame will only select the annotation elements that are in the annotation layer in the map frame. In the Map Composer window, these annotation elements are supported in addition to the regular annotation elements:

♦ neatlines, grid lines, and tick marks ♦ scale bars ♦ legends Editing Map Annotation Every map composition has an accompanying overlay (annotation) file with the .ovr extension. For example, the annotation for a map file called MyFirstMap.map would be MyFirstMap.map.ovr. This file is automatically created when you create a map composition and it is, by default, the top layer in the Map Composer window. Use the same tools and dialogs for editing map annotation that you use for editing regular annotation in a Viewer, with the addition of those for the elements listed above. Care should be taken, however, in selecting the annotation units for use in a Map Composer window.

Neatlines, Grid Lines, and Tick Marks The following map annotation elements can be added to a map composition with the Set Grid/ Tick Info dialog:

♦ A neatline is a rectangular border around a map frame. ♦ Tick marks are small lines along the edge of the map frame or neatline that indicate regular intervals of distance.

9

Map Annotation

♦ Grid lines are intersecting lines in the interior of the map frame that also indicate regular intervals of distance. Usually, they are an extension of tick marks. A set of these elements for a map frame is actually a group of line, text, and rectangle elements that is automatically generated to your specifications.

☞ The line style for the grid/ticks and the text style used to label grid/ticks are specified with the Annotation Styles dialog, and should be set in advance. Geographic grid/ticks cannot be placed on map frames whose layers are not georeferenced. 4. To create these elements, click

icon on the Annotation Tools palette:

Then click in the map frame for which you want a neatline, grid lines, and/or tick marks. The Set Grid/Tick Info dialog is opened.

☞ These elements are configured around an existing map frame. However, they are not a part of the map frame, and will not move or resize with the map frame. Always add these elements after the map frame position and dimensions are set. Degrees and Lat/Lon Data You can use decimal degrees or degrees-minutes-seconds for your grid/tick increments only if the map data have projection information and are registered to Lat/Lon. If the data are registered to Lat/Lon, options to use meters and feet for grid/tick increments are not available. Levels of Grids/Ticks Non-geographic grid lines and tick marks can be organized into levels, which allow sub-units to be denoted. The illustration below demonstrates three levels of tick marks. level 1 level 2

level 3 The space between tick marks is called a division.

Scale Bars A scale bar is a map annotation element that illustrates the scale of a map frame. It shows the distance on paper that represents a geographical distance on the map. ERDAS IMAGINE provides cartographic quality scale bars.

10

Map Annotation A scale bar for a map frame is actually a group of line and text elements that is automatically generated to your specifications. You can create scale bars for more than one map unit at a time. The resulting scale bars will be in a group together and will be aligned as you specify. Creating Scale Bars

☞ The text style used in the scale bar is specified with the Text Style Chooser dialog, and should be set in advance. 5. To place scale bars, click

icon from the Annotation Tools palette:

6. Hold and draw a box in the Map Composer window outlining the length and location of the scale bar(s) — you can change the size and location later, if needed.

☞ You can create scale bars only for map frames containing georeferenced data. 7. Then click in the map frame for which you want the scale bar(s). The Scale Bar Properties dialog is opened.

Legends A legend is a key to the colors that are used in a map. Legends are especially useful for maps of thematic data displayed in pseudo color, in which each color represents a different feature or category. A legend can also be created for a single layer of continuous data displayed in gray scale or a vector layer. A legend for a map frame is actually a group of text and rectangle elements that is automatically generated to your specifications. A legend is configured based on an existing map frame. However, it is not a part of the map frame — it is simply annotation. A legend will not be updated if the map data or colors change. Also, changing the color of a legend patch will not affect the color of the map data. Always add a legend after the map frame data and colors are set. Creating a Legend

☞ The text style used to label a legend is specified with the Text Style Chooser dialog, and should be set in advance. 1. To create a legend, you must start with a map frame that contains thematic data displayed in pseudo color, a single layer of continuous data displayed in gray scale or a vector layer. 2. Click on

icon in the Annotation Tools palette:

11

Map Annotation 3. Click in the Map Composer window where you want the legend to appear - you can reposition and resize the legend later. 4. Click in the map frame for which you want to create the legend. The Legend Properties dialog is opened. Parts of a Legend The different parts of a legend are as follows. These terms are useful in describing the legend properties.

♦ The title is the overall title of the legend. By default, it is “Legend.” ♦ An entry is one row of the legend table, representing one class or file value. ♦ A patch is the colored rectangle that represents the color or style that is used in the data in the map frame.

♦ A heading is the name of an attribute that appears in the legend. Each descriptor has a heading such as “Class Name” or “Histogram.”

♦ You can arrange your legend in newspaper-style columns. These are not to be confused with the columns for each attribute.

Setup for Output to a Film Writer

Setup for Output to a Film Writer If you want to output a map composition to a film writer device, you must set up the correct parameters in ERDAS IMAGINE and in the map composition itself. This setup allows you to create a map composition which is not resampled in the printing process. The map composition is then output to an .img file, which can be converted to BIL or BSQ format for printing to film. Follow these steps to create a map composition which has not been resampled for output to a film writer: 1. Edit the file <$IMAGINE_HOME>/etc/units.dat using a text editor and set the default device_pixels to equal your output device. The default is 300 dpi. (Replace <$IMAGINE_HOME> with the name of the directory where IMAGINE resides.) 2. Start ERDAS IMAGINE by typing imagine at a command prompt. 3. From the Viewer, select File | Open | Raster Layer... In the Select Layer To Add dialog, select the raster layer to be printed in the map composition. Make a note of the number of Rows and Columns, as displayed at the bottom of the dialog. 4. Select OK to display the layer in the Viewer. 5. Display any annotation layers over the image in the Viewer. 6. From the Viewer menu bar, select File | New | Map Composition... to create a new map composition with these parameters: a. Set Map Width: to equal columns of your raster layer plus the desired number of extra pixels for marginal annotation. At 300 dpi, 300 extra pixels leaves one-half inch margin on each side. Example: 2450 + 300 = 2750 b. Set Map Height: to equal rows of your raster layer plus the desired number of extra pixels for marginal annotation. Example: 1394 + 300 = 1694 c. Set Units: to device pixels. 7. From the Annotation Tools palette, use the Map Frame tool to select the raster layer and locate the approximate position of the map frame, following the instructions which display on screen.

13

Map Series Templates

Map Series Templates Introduction Map series templates are used in conjunction with the Map Series Tool to produce standardized map compositions for raster, vector, and annotation data layers. A map template is a map composition file (.map) and the accompanying annotation file (.map.ovr), which is produced by the Map Composer. Default map templates for some standard scales are distributed in the $IMAGINE_HOME/etc/ maptemplates directory. These default map templates are based on the standard United States Geologic Survey map series. You may use these templates or create customized templates for use with the Map Series Tool. Map series templates are created and edited as a map composition using the Map Composer tools. New templates may be created like any other new map composition by selecting the Map Composer, New Map Composition... option. You may find it easier to make a copy of an existing template by saving as a new name and editing the new template composition. Another alternative is to create a map series composition using one of the default templates, modify that composition, and then use it as a template for other map series compositions.

How Templates Work A map series composition is created from a map series definition and a map composition template. A modified copy of the map template is made for the map series composition. Certain map objects in the template may be static and will simply be copied from the template to the map series composition. Other map objects in the template may be dynamic and will be changed to accommodate the specific map series definition. These dynamic objects may have their contents changed, such as the map title, or have their position changed relative to the primary map frame in the composition. Dynamic objects are identified to the Map Series Tool by using keywords in object’s name and description fields. All the style attributes, such as line styles, colors, fonts, etc., defined for the template’s objects will be maintained in the map series composition. A detailed description of the dynamic map template objects follows. The Primary Map Frame In a map composition, map frames exist which contain raster, vector, and annotation data layers for a specified scale and area. Since more than one frame may exist in a map composition, the first frame created is interpreted by the Map Series Tool to be the primary frame. This primary frame is the frame in which the contents will be changed based on the map series definition.

43

Map Series Templates Other frames may exist in the template but can only be copied and position-locked by the Map Series Tool (see below). Since the map frame scale must be maintained, the Map Series Tool changes the primary map frame by recomputing the extent and position of the frame based on the map series definition. In general, since map definitions are based on latitude/longitude, map definitions in northern latitudes will have a narrower extent in X than map definitions in southern latitudes. This principle is important in determining the paper size of the map composition template. Make sure that the paper is defined such that all the map series utilizing the templates will fit on the paper. Following the calculation of the new frame extents, the map series map frame is positioned such that it is centered relative to the frame in the template. Also, although the map frame will remain rectangular, the data layers contained in the map frame will be cut out based on the true map series coordinates, leaving background fill between the map frame and the data. Secondary Map Frames Other map frames may exist in the map template following the primary map frame. These frames may contain raster, vector, or annotation layers and are normally used for logos or referencing images. The Map Series Tool will not change the content of secondary frames but will allow for position-locking relative to the primary map frame. Grid/tick systems may be defined for a secondary map frame but the Map Series Tool will not change the grid/tick contents. See ‘Dynamic Objects, Position-locked secondary frames’ below. Grid/tick Systems If grid/tick systems have been defined in the template for the primary map frame, their positioning and labeling will have to be adjusted to reflect the map geometry of the map series definition. Grid/tick systems are defined by a starting map position and a spacing parameter. The Map Series Tool must recompute the starting map positions but will maintain the spacing between grid/ticks as defined by the grid/tick system in the template. All other grid/tick properties, such as tic length inside and outside the frame, using full grids, etc., will be maintained from the template to the map series composition. Ordering of the Grid/tick Systems Since multiple grid/tick systems may exist for a frame and the grid/tick positioning and labels are automatically recomputed, overlapping labels may occur. To prevent this from happening, the Map Series Tool will delete overlapping labels based on the ordering of the grid/tic systems. The ordering is determined by alphabetically sorting the grid/tick name field from the Grid/tick Properties Tool. The labels of the first alphabetically-named grid/tick system will take priority over other labels if overlap occurs. If no names are specified in the grid/tick properties, the ordering will be in the order created. Since this feature exists, the overlap of grid/tick labels which may occur when the template is being created is not important.

44

Map Series Templates Map Projections of the Grid/tick Systems Grid/tick systems may be in any of the map projections supported by IMAGINE. There are several considerations when selecting the map projections for the grid/tick systems of the templates.

♦ The default grid/tick system is the system which is created when the Output Projection is NOT set. This grid/tick system will inherit the projection of the data layers on which it is applied. This grid/tick system should be created first when making the template because once an Output Projection has been set by the Grid/Tick Properties Tool, it cannot be unset and restored to the default mode.

♦ Geographic grid/tick systems may be created by setting the Output Projection in the Grid/tick Properties Tool to Geographic. This system is normally desired since the map definitions are based on geographic coordinates. The spheroid and datum parameters of the geographic projection will not be considered if they differ from the spheroid and datum parameters of the map projection of the data layers defined in the Map Series Tool. It is assumed that the geographic grid/ticks in the map series composition should have the same spheroid and datum parameters as the imagery in the frame.

♦ Grid/tick systems in other projections should only be specified in a template which will be used for maps in areas within the projection definition. A grid/tick system having projection parameters specifying a certain UTM zone, State Plane zone, or standard parallels and central meridians may not be meaningful for map areas in other parts of the world.

♦ Grid/tick systems are an object group created by the Grid/tick Tool. The grid/tick group maintains information defining the grid/tick parameters which will be lost if it is ungrouped, and will not be restored if it is grouped again. Ungrouped grid/ticks will not work correctly with the Map Series Tool.

☞ NEVER ungroup a grid/tick group in a map series template! Dynamic Objects To create the map series composition, it is necessary to replace or relocate certain objects in the template with appropriate attributes of the map series definition. The mechanism for identifying these dynamic objects is by matching keywords in the “Name” and “Description” field in the objects’ property boxes. Replacement Attributes The Name field identifies the replacement attribute for a text object. In the case of the North Arrow group, it may also identify certain position attributes.

45

Map Series Templates

♦ Map title. Any text object in the template with the name property equal to “<Title>” will have its contents replaced with the title of the map series from the Map Series Tool CellArray column entitled <Title>. The alignment properties of the text object will be maintained so that if the length of the string changes, it will remain aligned either, left, centered, or right as specified in the template text object.

♦ Map region. Any text object in the template with the name property equal to “” will have its contents replaced with the region of the map series in the Map Series Tool CellArray column entitled . The alignment properties of the text object will be maintained so that if the length of the string changes, it will remain aligned either, left, centered, or right as specified in the template text object.

♦ Map state. Any text object in the template with the name property equal to “<State>” will have its contents replaced with the state of the map series in the Map Series Tool CellArray column entitled <State>. The alignment properties of the text object will be maintained so that if the length of the string changes, it will remain aligned either, left, centered, or right as specified in the template text object.

♦ Adjacent map titles. Any text object in the template in which the name property equals one of the following will have its contents replaced with the map title of the map in the respective position: “”, “<South Title>”, “<East Title>”, “<West Title>”, “”, “”, “<Southeast Title>”, “<Southwest Title>”. The alignment properties and position of these text object will be changed so that they will be properly positioned at the sides and corners of the frame. However, the rotation angle of these text objects must be specified as parameters of the objects in the template (i.e., the angle will be maintained). Adjacent map titles take priority if overlap occurs with the grid/tick labels.

♦ Grouped objects. Any object group containing one or more of the above text objects will allow for those text objects to be modified if the group name property equals “”. This keyword identifies for the Map Series Tool a group object in which to descend to find text member objects to modify.

♦ North arrow. A special group object in the template with the name property equal to “” will have its contents modified to accurately reflect the true north and grid north of the map frame. Within the object, members are also identified with keywords. These group members are:

46

Map Series Templates - A text object with the name property equal to “” will be positioned immediately above the grid north arrow. - A symbol object with the name property equal to “” will be positioned immediately above the true north arrow. - A polyline object with the name property equal to “” will be rotated to point to grid north. - A polyline object with the name property equal to “” will be rotated to point to true north. - A polyline object with the name property equal to “” will be positioned halfway between the longest of the grid north arrow and the true north arrow. - A text object with the name property equal to “” will have its contents replaced with the rotation angle in degrees. It will also be positioned immediately above the angle base line. - A text object with the name property equal to “” will have its contents replaced with the rotation angle in mils (radians x 1000). It will also be positioned immediately below the angle base line. If any of the above objects are omitted in the template they will also be omitted from the north arrow created in the map series composition. Positioning Attributes

♦ Position-locked objects. Any object or group in the template can be identified to the Map Series Tool to be positionlocked relative to the frame. As mentioned above, the frame extent and position are dynamic and will be changed to maintain scale. It may be desirable to have objects in the map series composition maintain their position relative to the frame. Keywords in the description field of the object’s properties allows for this position locking. If the Description field of an object’s properties begins with “” then the object may be locked relative to the frame. Keywords following the keyword indicate to which side of the frame the object is to be locked. The possibilities are: “”, “”, “”, and “”. Using this mechanism, objects will maintain the same distance from the specified side of the frame in the map series composition as existed in the template. You may use two keywords to identify adjacent sides of the map composition. For example, you may use both and to keep the object positioned a constant distance from the bottom and right sides of the map composition. Using keywords for opposite sides together is ambiguous. Using both and will produce unpredictable results.

47

Map Series Templates

♦ Position-locked secondary frames. Secondary frames in the template can be identified to the Map Series Tool to be positionlocked relative to the primary frame. While the keywords are defined the same as for positionlocked objects (see above), the mechanism for identifying the keywords to the Map Series Tool are different. This is because frames in the map definition are not annotation objects and therefore, do not have the name and description fields available. Identifying secondary map frames for position-locking requires specifying the position-locking keywords as the frame name in the Frame Properties Dialog. If a grid/tick system is defined for a secondary frame and the secondary frame is identified to be position-locked, the grid/tick group should be identified to be position-locked in the same manner.

Tips for Making Templates 1. Before creating custom templates you should have experience using the annotation and map composition tools in IMAGINE. It will also be helpful to be familiar with the templates and the Map Series Tool’s utilization of the templates. Make copies of the default templates and use the Map Composer tools to explore the objects’ parameters, and keywords. Then use the default templates (or copies) with the Map Series Tool to see how the map series composition is formed from templates by changing the dynamic objects. 2. Make the paper size large enough to accommodate frames for different projections at different latitudes. When in doubt, make the paper large and cut it down after printing. Another alternative is to make different templates for different projections or geographic positions. 3. When defining the primary frame parameters, set the frame scale first to the desired scale and then set the option to maintain the scale while adjusting the frame and map positioning. Normally, the frame should be centered on the paper, since the frame for the map series composition will maintain the same center. Also, it may be useful to have the Map Series Tool already running and the map series displayed in the Viewer so the target map boundary may be used to define the frame area. 4. Objects placed close to the frame in the template should be locked to that side of the frame to prevent the frame from overlapping the objects. See ‘Dynamic Objects, Position-locked objects’ above. This is especially true for the left and right sides, which fluctuate the greatest. 5. When creating the keyword objects, it is generally faster and safer to copy and paste these objects from a default template which already exists. This will prevent typos in the keywords. Copying and pasting the north arrow group can save a great deal of time, since it is made of several keyword objects. After the north arrow group has been pasted, its size and styles may be changed without effecting the keywords. Remember, if the north arrow group is ungrouped, it must be regrouped and given the name which was lost in the ungroup.

48

Map Series Templates

☞ Remember: NEVER ungroup a grid/tick group in a map series template! 6. Once the template is completed and has been saved, it may be necessary to edit the secondary frame names if position-locking is desired. See ‘Dynamic Objects, Positionlocked secondary frames’ above. This will have to be done each time the map composition is saved since Map Composer creates default frame names and overwrites the map file.
