Lurker Posted November 18, 2020 Report Share Posted November 18, 2020 is it the same problem with your indonesian topic? basically you can manipulate all remote sensing data using remote sensing software like ENVI or ERDAS. Quote Link to comment Share on other sites More sharing options...

intertronic Posted November 25, 2020 Report Share Posted November 25, 2020 (edited) there is also a new tool in arcgis pro called "Pixel Editor" if you need to correct the values for this tool you need the Image analyst license. https://pro.arcgis.com/en/pro-app/help/analysis/image-analyst/editing-elevation-pixels.htm depending on your task or your licence you can also use the "Raster Calculator" (needs spatial analysis). For example if you have a polygon with the elevation data and you want to substitute the values on your raster (polygon to raster, then use the conditional function > con() https://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/con-.htm Edited November 25, 2020 by intertronic 1 Quote Link to comment Share on other sites More sharing options...
