RS_Union

Introduction: Returns a combined multi-band raster from 2 or more input Rasters. The order of bands in the resultant raster will be in the order of the input rasters. For example if RS_Union is called on two 2-banded raster, raster1 and raster2, the first 2 bands of the resultant 4-banded raster will be from raster1 and the last 2 from raster 2.

Note

If the provided input Rasters don't have same shape an IllegalArgumentException will be thrown.

Format:

RS_Union (raster1: Raster, raster2: Raster)
RS_Union (raster1: Raster, raster2: Raster, raster3: Raster)
RS_Union (raster1: Raster, raster2: Raster, raster3: Raster, raster4: Raster)
RS_Union (raster1: Raster, raster2: Raster, raster3: Raster, raster4: Raster, raster5: Raster)
RS_Union (raster1: Raster, raster2: Raster, raster3: Raster, raster4: Raster, raster5: Raster, raster6: Raster)
RS_Union (raster1: Raster, raster2: Raster, raster3: Raster, raster4: Raster, raster5: Raster, raster6: Raster, raster7: Raster)

Since: v1.6.0
