Does anyone know if there is a Sanborn Fire Insurance Map, map service? We are working on a historic survey of southwest PA that we would like to be able to view these historic maps as basemaps or add the rasters to our mapping to show different years. Since it is for a large area, it would be a lot of work for me to go about downloading individual rasters and georeferencings etc. Hoping there is a service somewhere.
Cheers,
Justin
