Can raster data be reprojected?
Yes, if the raster data file is small enough (less than 4 MB or so) and the change in projection is not too mathematically ‘intense’ for your computer. School desktop computers running AEJEE are often too slow to be effective at on-the-fly reprojection even though the software supports it. Both more computing power and more sophisticated GIS software are required to reproject raster images quickly when they are larger files. This problem can be solved by delivering raster images from an ArcIMS server to AEJEE via an internet connection. In this case, your computer requests a raster from a powerful ArcIMS server somewhere out there in internet world. The server reprojects the raster image in seconds and then sends it back for display in your AEJEE project, sort of like map messaging instead of text messaging. The weakness of this approach is that it requires a fast and dependable internet connection, and a map server that is not too busy processing simultaneous requests.
