Hi, I am trying to convert a raster to polygon in ArcGIS 10. I initially used the Extract by Attributes tool to isolate elevation ranges between 1900 and 3800 meters from a 90m DEM. I want to convert that into a polygon that I can use to clip an area of interest from some satellite tiles. When I convert from Raster to Polygon I get a grid instead of a polygon (Screenshot2). I also included an up close shot of the grid (Screenshot). I'm not sure why this is happening. The only options I have are to change the field parameter from Value to Count, but that also returns a grid structure. How can I create a regular polygon from this data? Any help is greatly appreciated....
Thanks,
Graham
