I used raster iterator tool in ArcGIS ModelBuilder read several raster files in IMG format and extract values of corresponding raster files to a point Shapefile using "Extract multiple values" tool in spatial analyst. However, names of the raster files are too long and in extracted Shapefile fields they do not make any scene.
How can I extract part of the raster files name and use it as corresponding field name in the shapefile once the data are extracted?
