Hi, For my mind the best software for this task is called MapServer. Just define GeoTIFF output format and ask for an image with the height and width you want. Then it will be easy to save the image and use it as a quick look layer.

I have created a tile index from them and have created a mapfile that uses this index to tile the files for display accordingly. They do display properly. I do beleive they have multiple resolution images within each tile, but when zoomed out to the extents of the town, it can be an intensive task to load up images for all six tiles. I think the easiest way to remedy this is to use the mapfile to shut off the Ortho Aerials at a particular scale and swap in the lower res jpeg that places over the same extents. My question is based on personal experience, what is the easiest way to go about this? Something as simple as 'print screen'? Are there any good freeware jp2 viewers that I can use to save a particular view of 6 tiles down to perhaps a tiff file? The ortho's need not have transparency themselves for this particular instance. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
