Raster data, including, but not limited to, elevation models or remote sensing imagery, is commonly used in many workflows. The following exercises show common raster processing and analysis tasks such as clipping to a certain extent, creating relief, slope rasters from digital elevation models, and using the raster calculator.
Analyzing raster data
Clipping rasters
To begin the process of clipping rasters, load the SR_50M_alaska_nad.tif raster and the regions.shp (both from our sample data) as the layer to be clipped. Now zoom to the extent of the regions.shp and select one region using the selection tools. In this example, we will clip the raster to a selected layer within the polygon shapefile. From the main menu, select...
