Module 4, Basic analyses with grid data

Work-in-progress Future topics:

• creating raster data from polygon feature data: poly2grid
• reading raster data from GeoTIFF files
• element-by-element operations
• defining and using a compacted domain and basegrid to do less work
• defining kernel and various distance decay functions using range and dist2
• use combine(raster, kernel) and third_rel := first_rel + second_rel to define focal operations.
• Faster 2d convolutions: https://geodms.nl/docs/potential-with-kernel.html
• Grid2Polygon: https://geodms.nl/docs/grid-2-polygon-example.html
• grid2polygon scripting to simplify zoning data while maintaining topological relations: https://geodms.nl/docs/poly-to-grid-to-(simplified)-polygon.html
• shortest paths through a terrain: griddist
• districting raster data: https://geodms.nl/docs/district.html
• other raster functions: https://geodms.nl/docs/grid-functions.html
