Raster

• Rationale
• Installation and Configuration

Examples

1. Create a raster and fill with values
2. Open a raster and fill with values
3. Sum two rasters cell-by-cell
4. Multiply raster by constant
5. Apply a custom function on a four-cell moving window
6. Calculate statistics for a circular moving window
7. Calculate statistics for a square moving window
8. Use the optional value type for nodata values
9. Iterate over square windows centered on each cell
10. Create a raster of random values based on a probability distribution
11. Apply a function to a subsection of a raster
