Unfortunately, raster data is often relegated to a supporting role in the world of geospatial analysis, serving as a simple base map for the ‘real’ work vector data analysis. However, this is an unfair categorization. Both individually and collectively, every pixel that comprises a raster layer contains information that exposes a wealth of valuable data, reveals patterns in data distribution, and creates a more complete picture of the area of study. In this GeoTalks Express presentation, we spend an hour introducing some of Global Mapper’s raster processing tools including raster calculation, raster reclassification, and feature extraction from raster data.
