Oct 7, 2013 at 10:18 comment added Bandrush Barda Sorry. Which version of ARCGIS has Symmetric Difference tool? I cann't find it in ARCGIS 9.2.
Oct 7, 2013 at 8:55 comment added Antonio Falciano If you are interested in a shapefile you can follow another approach (more accurate): create a polygon shapefile containing only a feature covering the whole study area, then calculate the Symmetrical Difference with your lake shp and put 1 in a new field, e.g. "MASK_VALUE". Finally, you have only to merge the lake with the symmetrical difference. Hope this helps!
Oct 7, 2013 at 8:40 comment added Bandrush Barda There are 2 choices. One is value, another is count. I tried both of them. But results are the same.
Oct 7, 2013 at 8:32 comment added Antonio Falciano @BandrushBarda Have you set the "raster field" (optional) parameter with the "Raster to polygon" tool?
Oct 7, 2013 at 8:16 comment added Bandrush Barda I need a shapefile or AOI file again after these steps you suggested to do subset. I have already got the mask file I desired (0 and 1). But I used "Raster to polygon" tool to get polygon file of lakes again, the values I desired disappeared, just FID number, shape, ID, Gridcode numbers have left in attribute. How should I do this?
