However one would presume they would check the legality of the source imagery.Ryan Strynatkahttps://www.blogger.com/profile/06588216957200772125noreply@blogger.comtag:blogger.com,1999:blog-7547877823093266529.post-66196702910048789072008-10-29T11:49:00.000-03:002008-10-29T11:49:00.000-03:00Did you ask them if they take free data from GIS w...Did you ask them if they take free data from GIS websites and sharge people money for the data? I looked in my area (seacoast New hampshire) and found that they had 1962 and 1974 data up there and were charging for it. I worked on the orthorectification of that imagery for two years. It was funded with public funds and meant to be freely available to the public. It's a shame these guys take free data and then turn around and sell it to people who don't know better. I'm not impressed.Anonymoushttps://www.blogger.com/profile/18161200824427631830noreply@blogger.com
