I am using Arc 10.0........
I have 2 files... a raster made from a Polyline shapefile and a masked area from a polygon...
[ATTACH=CONFIG]15077[/ATTACH]
I am trying to use Raster Calculator Map Algebra to convert the values of 0 from blue area to NoData in the overlapping area behind there...
This expression below converts those pixels to 0..
Con("polrecl", 0, "maskdpoly")
I want to convert to "NoData" instead because I want to do statistics on the area inside the boundary only.
I tried Con("polrecl", NoData, "maskdpoly") but this doesn't work...
I am new to this stuff, can anyone assist?
