Hi, The ransom idea is interesting.
I believe Terraserver has USGS DRG, DOQ, and UrbanArea hi res DOQ available as a seamless coverage over US, accessible through an OGC WMS. http://terraservice.net/ogccapabilities.ashx?version=1.1.1&request=getcapabi lities&service=wms Here are a couple of examples. The scale of DRG returned depends on the size of footprint requested. Here are a couple examples GetMap requests: http://terraservice.net/ogcmap.ashx?version=1.1.1&service=WMS&ServiceName=WM S&request=GetMap&layers=DRG&format=image/png&transparent=TRUE&srs=EPSG:4326& bbox=-104.90266144275665,38.789952754974365,-104.69096267223358,38.997937560 08148&WIDTH=1000&HEIGHT=982 http://terraservice.net/ogcmap.ashx?version=1.1.1&service=WMS&ServiceName=WM S&request=GetMap&layers=DRG&format=image/png&transparent=TRUE&srs=EPSG:4326& bbox=-104.79460379481315,39.072429625317454,-104.76692690700292,39.099223209 545016&WIDTH=1000&HEIGHT=968 OpenGIS Web Services, http://www.opengeospatial.org/, hold a lot of promise for filling the need for opensource data resources.
