Multi Criteria Overlay Analysis with QGIS

This video tutorial aims to provide and explain a detailed procedure on how to perform Multi-Criteria Overlay Analysis in QGIS. You will be introduced to how one can compose more than one layers of geospatial data for the purpose of assessing different aspects that you can base your decisions on. The steps involved in overlay analysis will also be outlined here with added focuses on the criteria definitions as well as possible weightages assigned to several factors involved in the analysis.

In this tutorial, you will be introduced to key functions of the QGIS environment and you will work on the layer styling of the data, the data reclassification as well as the usage of the Raster Calculator in the context of the weighted overlays. At the end of this session, you’ll be able to carry out sound multi-criteria analyses and derive meaningful conclusions from voluminous data packages. Regardless of the type of problem you are solving, whether it is in site selection, environmental impact, and any any other problem that requires spatial decision making, this tutorial is going to be very useful and helpful to you in sharpening your skills and making your analysis easier.
