The 3rd Open Source GIS User Group meeting was a presentation on QGIS. The following is an outline of what was presented. A corresponding short guide is provided for you to use to explore QGIS: Download IntroQGIS pdf.
Quick Introduction to QGIS 2.14 LTR
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

Map Scale: ratio, measurement unit defaults (project CRS)
