In order to do so, I have to correct the given imagery for shadows before I classify it. My method is to create a mask where the shadows are NoData, and merge it with an image with a spectrally enhanced image. However, when I merge or mosaic the two images, the resulting image takes on the high values of the spectrally enhanced image. Is there a way to combine the images while maintaining the RGB values for the mask image, and fill the holes with the values of the enhanced image?</P> Fri, 22 Mar 2024 22:47:27 GMT https://community.esri.com/t5/arcgis-pro-questions/combining-raster-datasets/m-p/1399876#M80836 CollinCampagna 2024-03-22T22:47:27Z https://community.esri.com/t5/arcgis-pro-questions/combining-raster-datasets/m-p/1401567#M81041 <P>You can use a combination of the is Null tool and Con to fill NoData values from one raster with values from another.
