Advanced GIS: Raster Data Analysis

Map of Devastating 2003 Heat Wave in the Netherlands Observed from MODIS Satellite. Mehdi Aminipouri (PhD Candidate in Geography at SFU)

Raster data is continuous, pixelated data. For example, aerial photographs, LIDAR data, and digital elevation models store information as raster data. In contrast, vector data is discrete and is stored as geometric objects: points, lines and polygons. The tools available to you, and the kind of analysis you can conduct, with raster data are different than those for vector data. This session will focus on working with raster data in ArcGIS.

By the end of this workshop, participants will be able to:

  • distinguish between different types of raster data;
  • work with digital elevation models (DEMs);
  • explore raster surface data (hill shade, contour, aspect data);
  • create and work with mosaic datasets.

Software: ArcGIS Desktop 10.6 (participants will not need their own computer)
