Does anyone know if Birdseye TOPO US and Canada is a better detailed map than Louisiana TOP 1:24k?
Birdseye topo should be the same maps you will see here. Zoom in on your area and check the box on the left for scanned topo maps. http://viewer.nationalmap.gov/viewer/
This is a completely different kind of mapping called raster imagery. It's a scan of a paper map. The Lousiana topo is a vector based map that features lines and dots that connect coordinates. This gives a very different appearance and each type map has its advantages.
