Hi all.Another good tool is TerraFetch, by MapShots ( shareware if useful ):http://www.mapshots.com/downloads/terrafetch.aspIt allows auto-fetching of the USGS Terraserver images for defined areas.These will need reprojection for use with Ground2K4, SBuilder(?), or resample... but they should be useable for AirportFor Windows, SGX, or FSSC.Dick

Thanks. I'm getting so many mapping tools now that just keeping track of them all and my data is becoming a problem. It seems like maybe MicroDem has a data base included with it but I have yet to figure out exactly how to use that.scott s..
