I don't really know what his aim is exactly other than to preserve
this resource and probably make available as large seamless TMS layer.
But I trust Grant knows what he is doing and why as he has done this before.
One use case a DEM does not address is place and feature names and
locations, old topo maps have that information usually, DEM does not.
I have used them extensively in the past with GNIS data points which
are gridded to like 30" arcs or something like that, topo maps are
The Perry-Castañeda Library Map Collection is one such example of a
similar very valuable resource.
And again, if Grant is asking, I am supporting even if he wants to
just make them his desktop wall paper.
