To Change the pixel value in ArcGIS 10. Is it possible to edit the values of pixel of an image RGB? For example: I select a pixel with value 3,44,125 and want to modify it for 0,0,255
The suggestion is correct however, it seems inept that simple and straight forward editing of a cell value in ArcGIS isn't possible. I see various efforts to write third party tools to do this but they don't seem to work well. Is this hard? I am always surprised at what Arc can't do, for example, some simple functions like easy GPS connections and cell edits in a raster.
This can be done with the latest version of the "Grid & Raster Editor for ArcMap". It supports many editable single and multi-band rasters in ArcGIS. The toolbar provides a set of tools to change the value of one or more cells. With these tools it is possible to:
draw a free line or edit single cells (pencil)
draw straight lines from one point to another (line)
draw a solid polygon (polygon)
change the value/color of a zone of cells with identical values (paintcan)
replace one value with another value in the entire grid (value replacer)
create a selection area in the map to limit the working area for the above operations (edit area)
