whitedolphin Posted February 7, 2013 Report Share Posted February 7, 2013 Guys, I have a raster that contains only two values, 0 and 1. The zero values represent the land area whereas 1 is water. There are some land pixels that I need to 'erase'. Anybody knows how to do that in Idrisi or other software perhaps. I tried ArcScan but the Raster Painting toolbar is inactive, even after I start editing the raster layer. I could not understand why. Anybody willing to throw some light?

yousef2233 Posted February 7, 2013 Report Share Posted February 7, 2013 Using ArcScan in ArcGIS: note that: ***** The only supported formats for Raster Cleanup are TIFF, IMG, and GRID ***** enable arcscan extension 1 - Put a featureclass in the dataset you have the image, add it in arcmap 2 - Start editing the featureclass by editor toolbar 3 - in the arcscan, start cleanup Quote Link to comment Share on other sites More sharing options...

Ivanov_da Posted February 13, 2013 Report Share Posted February 13, 2013 I applied it for ESRI GRID. ArcVeiw + Spatial Analayst and script GRID Pig Tools. It`s possible to set NO DATA to any chosen value, or inverse - replase NO DATA to any chosen value. Rastr -> ESRI GRID -> processing -> Rastr.
