How to become a Raster Master (QGIS)

When using GIS, there are two main data models. A vector data model stores real-world objects as points, lines, or polygons. A raster stores objects as pixels. The session compares the two models using some basic tools in QGIS. The software version used in this video is 3.40.11. Note: the data used in this video is restricted to Dalhousie University students. Others may find it useful to watch and try to use the tools on their own data. 0:00:00 Introduction/Start 0:02:55 Different models for representing geographic features 0:03:58 Comparing Raster and Vector data models 0:09:33 Types of Raster data 0:10:17 Types of thematic rasters 0:13:28 Image rasters 0:14:26 Zones and Regions 0:16:35 Cell size 0:19:25 Starting Hands-on example 0:21:20 Getting started.
