How to extract multi values to points in ArcGIS?
Any combination of rasters (single band or multiband) can be specified as input. A cell value will be extracted for each input raster and a new field containing the cell values for each input raster are appended to the input point feature class.
How are output field names created in ArcGIS?
Output field names are created from the name of the input raster by default; otherwise, you can specify a unique name for each field to store raster values. When the input is a multiband raster, a field will be added for all bands with a b1_, b2_, …bn prefix added to the name of the output field denoting the band number.
