Raster to polygon problems

Question asked by grastafaram on Apr 25, 2012

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
