I have several data arrays representing different regions within a large area. Each array has latitude and longitude information. I want to produce a single image with the regions placed on a common underlying map. I have tried using MAP_SET to define the base map and then, for each region, used MAP_PATCH to warp it into its proper place on the larger base map. The problem is that I can't figure out how to display them all; when I try using TV, for example, the display window is wiped clean each time I add an image. It may be that the IMAGE function will work, but it isn't clear to me how I would use it in this application. The examples provided in the IMAGE documentation don't seem applicable to this problem. I would appreciate some guidance. Thanks.
