Purpose
The purpose of this tutorial will be to use multiple tools in Grass GIS [1] that will manipulate vector data. The example to be used in the tutorial will be the analysis of Ottawa City neighbourhoods to determine where would be the most appropriate place to live as a student attending Carleton University. This tutorial will use the following tools:
Extract- selection by attributes, Patch- patch vector layers together, Select- selection by location,
Overlay- clip tool, and Buffer- generate buffer
There will also be some coding using the command console for tools that are not included in the WxGUI.
This is a basic introduction to thematic mapping using the Grass GIS software vector analysis capabilities.
