I did not see any existing forums on this. Displaying Elevation raster floating point GRID for a large area (30 mile buffer of Idaho). In 9.3.1 I can see the stretch very nicely by default. But in 10, I have to zoom to raster resolution to see the contrast, otherwise it looks completely black. 9.3 has a check box in options for display raster datasets with contrast stretching. I do not see a similar option in 10. I'm concerned that it will print completely black as well. Just testing 10 now on a remote server, which is slow, 9.3 is a local install. Do I need to "upgrade" rasters created in 9.3 to use in 10? So then I tried an integer grid - several attributes, but only 109 records, but it is still trying to draw after 5 minutes.
