I'm looking to automate a procedure that will change a single cell value in a raster. I have a known x, y and z, and a raster. I need to change the cell value (closest to my x and y value) to the specified z value.
I've been doing this using Saga (change cell values [interactive] module) but I need a more automated method for use in a batch file or python script. I thought there may be a module for updating a raster cell based on point (vector) values? Note, I do not want to reclassify grid values, rather I wish to specify one.
I have access to QGiS, Saga and ArcGIS basic (without any spatial or 3D packages). If anyone can point me in a starting direction it would me much appreciated. Thanks,
