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 displays 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 do to this Intro to GRASS workshop page with detailed instructions on how to download it.

Data

First, we will need to download our data for open.ottawa.ca. Proceed to the following link, to download the traffic collision data from 2019. Click the download button. Then select Shapefile. Download the traffic red light violations here.

Methods

Start by launching GRASS GIS.
