Introduction
This tutorial will demonstrate how to do a vector analysis using GRASS GIS. By the end, you should be a little more comfortable using the program. Our goal is to use the 2020 Red Light Camera Violations data from open.ottawa.ca to make a map that display the safest areas in Ottawa to drive based on the number of traffic violations. If you do not already have GRASS installed on your computer, you can go to this Intro to GRASS workshop page with detailed instructions on how to download it.
Data
First we will need to download our data. You can download the Ottawa Traffic Collision data here. After you proceed to the link, click the download button, and select "shapefile." Once you have downloaded the Traffic Collision data, click here to download the Red Light violations data.
