Map Algebra is the math for raster datasets. The math-like expressions contain operators (for example,
InList) and functions (for example,
Some Map Algebra operators and functions return logical values:
True (logical value
False (logical value
0). Be aware of
NoData cell values because Map Algebra will not interpret this nonzero value as a true condition.
In this recipe, you will use Map Algebra expressions to identify the suitable sites for fruit orchards and reforestation. You will update the
LandUse raster dataset with the proposed forest and fruit orchard sites using a Map Algebra operator called
