Disclaimer

Please note that this Wiki has been created for GEOM 4008 Advanced Topics in Geographic Information Systems at Carleton University in order to demonstrate a method of change detection analysis using Free and Open-Source Software (FOSS). It is highly recommended that these steps are followed in the order that they appear to avoid confusion. The tutorial is set up to be performed on a Windows operating system.

Purpose

The purpose of the project was to develop a method to detect change in an environment using FOSS. This tutorial has been created to allow individuals who are not familiar with GIS to successfully complete this analysis using Whitebox (3.2.1). This tutorial will be carried out by analyzing the temporal changes that occur in a subsection of the Greater Toronto Area (GTA). The end result of this Wiki will be the creation of a change detection map using the write function memory insertion method. This will provide qualitative insight into the temporal change of land cover in a subsection of the GTA.

Data

In order to perform a change detection analysis, satellite imagery is required. For this tutorial, Landsat imagery of the GTA will be used and can be found by in the United States Geological Survey (USGS) Landsat image database using the search tool Earth Explorer.

Note: A free account with the USGS is required to download the required Level 1 satellite data and to also have the option for batch downloads.
