I have two rasters Ras1 and Ras2.
I want to change the Ras1.
In Ras1, there are few areas, lines, points I am interested having nodata cells and wrong data cells.(limited to interested areas only not talking about the entire Ras1 image)
For those interested areas of Ras1 having nodata cells and wrong data cells, I want to replace cell values with Ras2.
I have seen few tools replace values, but those are value specific ( ie. Replacing all "10" value cells with "56" in entire image) and conditon tools in arcgis, deals with null/no data values.
Is there any way, I can do Replacing Raster Values in Ras1 with Ras2 of my chosen area in the image?? Is there any way I can use arcgis / envi / erdas for this? Please guide me.
