Global Editing Tools

ThRasE provides two powerful global editing options that allow you to apply changes to multiple areas simultaneously.

Apply to Entire Thematic Raster

This option applies the changes defined in the pixel recoding table to the entire thematic raster.

Warning

This operation cannot be undone, so use with caution.

Apply Within Selected Classes

ThRasE enables you to apply recode pixel table changes selectively within areas defined by selected classes from another categorical raster file. This capability is crucial when corrections need to respect existing spatial boundaries or land management units. For example, you might need to reclassify forest types only within protected areas, correct agricultural classes exclusively in irrigated zones, or refine land cover classifications within specific administrative boundaries. This feature applies more precise and contextually appropriate post-classification corrections to the entire thematic raster.

Warning

The categorical raster file used to define constraint areas must match the projection and pixel size of your thematic map, but its extents can be different. This operation cannot be undone, so use with caution.
