NOTES:

QGIS installer Windows Standalone – 32 and 64 bit (you need to download every time there is an update) QGIS Long Term Release (LTR) - (stable version) Advanced installer OSGeo4W – 32 and 64 bit (just run the installer and update) QGIS Manual http://docs.qgis.org/2.14/pdf/en/QGIS-2.14-QGISTrainingManual-en.pdf Other on-line resources http://maps.cga.harvard.edu/qgis/ http://www.qgistutorials.com/en/ OSGEO4W - OSGeo4W is a binary distribution of a broad set of open source geospatial software for Win32 environments (Windows XP, Vista, etc)

NOTES:

The Open Source Geospatial Foundation... OSGeo was created to support the collaborative development of open source geospatial software, and promote its widespread use.

Plugins: OpenLayers – Image servers (OpenStreet maps, Google Earth, etc…) QConsolidate – consolidates QGIS project in specified folder Layer to labelled layer – use to move the label Spreadsheet Layer – convert .xls, .csv, .dbf to point data Real Centroid – generate points on the centroid of the polygon GEarthView - displays QGis view and features with attributes (selected layer) into Google Earth

Recommended Plugins: 1. QGIS2Web – export QGIS project to a web map 2. QGIS2threegs – export QGIS project with DEM to 3D view in a browser. 3. Azimuth and Distance Plugin – plot technical description 4. Points2One – plot lot data computation and convert it to line or polygon 5. Spatial Join - perform spatial joins dynamically, without creating a new table, using expression fields and refFunctions plugin (needed as dependency)

Recommended Plugins: 6. Spatial Query - spatial queries on vector layers 7. Quick Map Services – base maps like google earth, etc… 8. INASAFE – a free software that allows disaster managers to study realistic natural hazard impact scenarios for better planning, preparedness and response activities. 9. Clip Multiple Layers - Clip all displayed layers (rasters and vectors) with a polygon layer selected. 10. Heat Map - Creates a Heatmap raster for the input point vector 11. Processing - Spatial data processing framework for QGIS

Recommended Plugins: 12. AutoFields - allows you to configure vector fields to be automatically calculated for you when digitizing new features or modifying existing ones. 13. Photo2Shape - Create point shapefile from a set of geotagged images. 14. Topology Checker - A Plugin for finding topological errors in vector layers 15. Mmqgis 16. Evis 17. Db Manager 18. Line Offset

Troubleshooting Tips: 1. Missing “Polygonize” tool in the Processing Toolbox It may happen if you installed QGIS using Advanced installer. Solution : Install “python-shapely” library in the Advanced installer. 2. A “ghost” line appeared during digitizing Solution: save the layer edits, save the project, close QGIS Open QGIS and open the project.

Troubleshooting Tips: https://pypi.python.org/pypi/ExifRead Paste exifread folder to activate latest version of Photo2Shape C:\OSGeo4W64\apps\Python27\Lib\site-packages C:\program files\QGIS\apps\Python27\Lib\site-packages Map location settings for geosetter http://www.geosetter.de/map_google.html Website for br-exifextracter and geosetter 1. http://www.br-software.com/extracter.html 2. http://www.geosetter.de/en/

INASAFE Notes • Requirements: 1. At least 1 hazard and 1 exposure layers 2. Same Projection: ex: EPSG:4326 (WGS84) 3. Define what is exposure and hazard layer: 1. Make the layer active, click Keywords Creation Wizard 2. Select the exposure and hazard in dropdown menu “In the event of” “How many” 3. Click RUN
