Hi, What you want is the union of all the individual image polygons. At least it can be made with GIS applications like QGis or OpenJUMP. I don't know of any tool that could do it directly from command line but such can exist, though.

I don't need all of the interior grids within this shape file just the exterior vertices's. How can I convert this shape file so that it does not have the interior grid and just the exterior vertices's. I am displaying this shape file within UMN MapServer and I want to increase the performance by eliminating the drawing of the interior grids. Thanks, John Mitchell -- John J.
