I don't stop by Amiga Arts much these days but I happened to pop my head in and saw your message. For future reference, VRLI maintains a section in the Graphics A Vender Forum, GO VRLI or GO GRAPHAVEN. Both Clint and I check messages there a few times a day so you'll generally get quicker response if you leave messages regarding Vistapro there. There _is_ a program for converting the USGS ascii DEM files into Vistapro format. It's available in VRLI's library section of GraphAVen. It may be there in the form of a self extracting archive as MCNV.EXE, or it may be MCNV.LZH or MCNV.ZIP. The USGS format is ASCII text and is very verbose, 5 to 10 bytes per data point. Vistapro's format is binary and is much more compact, about 1 byte per data point. One thing you should also be aware of: many ASCII DEM files that you can get from the internet have been compressed with the unix "compress" program. You may need to uncompress the files before loading them into MCNV. You can find a DOS utility for this in the unix forums. You can often recognize a compressed file by a .Z extension. Yes, Vistapro was originally an Amiga program. Since version 3.0 I do the development on the DOS version and Clint Woeltjen ports the new features back to the Amiga platform. John.
