I have a rectangular raster image in ArcMap.
How can I produce a polygon which is just the extent of the raster image?
That is, I want to have a polygon layer with a single quadrilateral which is the edge of the image.
I've tried simply doing a Raster->Polygon conversion, but this tries to use the data in the image to generate the outline – all I want is the outline of the edge of the image.
I'm using ArcGIS Desktop 10.

If you have the "Spatial Analyst" then you can:
Another solution:
If your have 3D Analyst license then you can use the Raster Domain tool under 3D Analyst>Conversion>from raster (however it does not have the smooth function)
