Data Production and Editing Techniques

Productive editing techniques „ Typical

challenges when editing features

Sketching efficiently „ Managing feature selections „ Controlling feature snapping „

Sketching challenge #1 „

How can you quickly switch from a sketch tool to another tool and back to the sketch tool again…

…instead of interrupting your sketch to visit the toolbar?

Shortcut keys: E, C, X, Z „

„

„

„

Use the “E” shortcut key to toggle between the Sketch tool and the Edit Tool. Use the “C” shortcut key to pan Use the “X” shortcut key to zoom out Use the “Z” shortcut key to zoom in To see a list of all the editing shortcut keys, in ArcGIS Desktop help, on the Index tab enter “shortcuts, for editing in ArcMap”

Sketching challenge #2 „

How do you ensure that you accurately create an edit sketch using other feature options?

Use Sketch tool constraints „ „

Constraints -> Sketch Tool context menu Add sketch segments „ „

„

At „ „

„

Parallel Perpendicular Absolute XY Delta XY

With specific „ „ „ „ „ „

Length Direction Direction and Length Distance Deflection angle Tangent curve

Use the Trace Tool „

Adds sketch segments by tracing along selected features

Mitered

Beveled

Rounded

Sketching challenge #3 „

How can you use units different than the map units when you’re specifying distance for a sketch segment? Map units are feet but you need to specify the length in meters

Use unit abbr. after distance value „ „

Distance units are interpreted from entered value Distance entered is used regardless of map units

Distance Unit - Meter

Map Units - Feet

Sketching challenge #4 „

How do I change the radius of a curve that has already been created?

Traverse Tool „

Load sketch into the traverse tool to modify

Steps:

NOT available with ArcView license. Instead you can use the sketch constraints for accurately creating features.

• Select Sketch tool • Right click feature to change • Open Traverse dialog • Right click in dialog • Choose “Load Traverse From Sketch” • Modify the radius or parameters of segment

Selection challenge #1 „

With multiple selectable layers, how can you modify feature selection by individual layer?

Use the Selection tab & Attributes dialog „

Selection tab: right click on layer to: „ „

„ „

„

Zoom to selected features Clear selected features (for that layer only) Switch selection (for that layer only) Select all (for that layer only)

Attributes dialog: right click on feature „

„

Unselect features in a layer one at a time Can work with multiple selectable layers

Selection challenge #2 „

How can you make sure you’re selecting the right feature from overlapping selectable layers?

Parcel

Zoning

Use the Select “next” function „ „

Select feature, then press the N key Must point to first feature within the Selection tolerance

Box selected Selection tolerance

Press N

Press N

Poly selected

Line selected

Use this technique with overlapping features

Selection challenge #3 „

How can you avoid accidentally moving selected features?

Selected feature

Gap between features

Set the Sticky move tolerance „ „

Helps avoid accidental movement Prevents feature movement within tolerance

100 pixels

Snapping challenge #1 „

How can you visualize the snapping environment while you’re editing?

Snapping to vertex or edge? Snapping to which layer? Snapping tolerance?

Snap agents, tips and a shortcut key „

Snapping indicator Snapping indicator

Status bar Layer name

„

Snap tips

Snap agent type

If snap tips are turned on

Snap tip

„

Snapping distance „

View by depressing "T" shortcut key

Snapping challenge #2 „

How can you get more control over how features snap to one another?

Parcels: Vertex or Zoning: Edge

Snapping tolerance and priority „

„

Set snapping tolerance in the Editing Options dialog Or use the Snap Tolerance tool to interactively set the tolerance.

You can also: „

Prioritize layers in the Snapping Environment dialog Snap tolerance tool 27 pixels

Remember: • Press the ‘Spacebar’ to temporarily suspend snapping • Use the ‘V’ shortcut key to locate where vertices are

Snapping challenge #3 „

How can you over-ride the snapping environment? Snap to vertex, edge or endpoint of features irregardless of snapping environment OR

Avoid snapping to vertex, edge or endpoint of features even though snapping environment is set

Snap To Feature „ „

„

„

Snapping on-the-fly Overrides snap environment settings Snap to feature geometry without setting individual snap agents Snap to midpoint of a line or polygon boundary

Snapping challenge #4 „

How can you rotate a selected line feature on one end point and snap the other end to another feature?

Misaligned street feature

Rotated street feature

End point snapped to another street feature

Change the Selection Anchor „

With the Rotate tool Set snapping environment „ Select the line feature „ Press the “S” key „ Position the selection anchors „ Rotate the feature „

Selection Anchor

Auxiliary Selection Anchor

Snapping point You can also hold the Ctrl key down and use the Edit Tool to move selection anchors

Pivot point

Solving feature adjustment problems

Feature adjustment challenge #1 „

How can you quickly take a feature that resides in a non-editable layer and reproduce it in an editable layer?

CAD drawing or Coverage Lot lines layer

Copy Features Tool „ „

„

Copies both editable and non-editable data Copies data outside of Target layer spatial domain and pastes into target layer Scales selected features if you drag a box

The target layer must be the same type of layer (point, line, or polygon) as the one from which you copied. There is one exception to this rule— you can copy polygons into a line layer.

Feature adjustment challenge #2 „

What adjustment technique should I use and how do I get the Adjust command enabled?

Source

Displacement Links Destination

Spatial Adjustment „ „

Located on Spatial Adjustment toolbar Commands & Tools to modify coordinate locations of your data.

Adjustment methods used to: •Differentially scale, skew, rotate and translate data •Stretch or warp features •Moves end vertices of features in layer to the ends of adjacent layer Remember to create the correct number of links for the transformation method

Feature adjustment challenge #3 „

How do you adjust multiple layers with the same set of links?

Adjusting Multiple Layers „

To adjust multiple layers: Load layers into ArcMap „ From Set Adjust Data „

„ Specify adjustment layers

„

To reuse links Save to text file „ Use links menu „

„ Save Link File

Feature adjustment challenge #3 „

How can you migrate attribute values from one feature to another?

Attribute transfer „ „

Interactively transfer attributes between features Match common fields between layers „ „ „

Set source and target layers Specify fields to transfer Option to transfer geometry

What questions do we get asked? „ „

„ „

How do you change the coordinates of a feature? How do you create and remove donut holes in polygons? How do you ‘flip’ the direction of a feature? How do you update the attributes of many features?

„ „ „

Add a feature where you want the hole Select that “Holed” feature Choose Editor menu -> Clip Choose ‘Discard the area that intersects’ option

Removing donut holes in polygons „

Removing a Donut hole: Double click on the feature to modify it’s shape „ Open the Sketch Properties „ Right click on “Donut Hole” part and choose ‘Delete’ „

How do you ‘flip’ the direction of a feature? „

Flip command on the Edit Sketch context menu

Double click feature to modify it’s shape „ Right click shape to open the Sketch context menu • Developer Samples -> „ Click on the ‘Flip’ command • Flip Command • Bulk flip of selected features „

How to update attributes of many features? „
