Presented by: Stephanie Saephan
1. What is QGIS?
- Free, cross platform, opensource GIS software
- One of the most widely used OS GIS – very popular
- Started in 2002 as more of a data viewer and has since grown into a full blown GIS application
- On-going development with bug fixes and new features added on a regular basis.
2. Installing QGIS
- Stand-alone installer (current 2.16 and LTR 2.14) – recommended for beginners
- OSGEO4W windows installer (32/64bit, bundles other opensource packages) – recommended for advanced users.
- Can have multiple versions on same machine, but can only use one version at a time
3. QGIS Desktop – a demonstration of the software to include the following:
- Components of the user interface
- Installing QGIS plugins
- QuickMapService (basemaps)
- Configuring the user interface
- Moving toolbars and panels
- Hide/show toolbars and panels
- General global settings
- Coordinate Reference System (CRS) and Map Scale
- EPSG: European Petroleum Survey Group (open standard codes for coordinate systems, datums, etc. See spatialreference.org, prj2epsg.org)
- Default global CRS in QGIS (EPSG: 4326 or WGS84)
- Map Scale: ratio, measurement unit defaults (project CRS)
- Adding and viewing spatial data
- Shapefiles (zipped and unzipped)
- Geodatabases (file gdb – read only for gdb created with AG10.x)
- WMS, WFS
- Symbology options
- Labeling options
- Print Composer – making a map

I am planning the next open source GIS user group meeting, for sometime in September. If you know open source GIS and would like to do a presentation, demonstration, or workshop please let me know.
