"NGA Map Sale Change
Back in November 2004, NGA stated (pdf ) in the Federal Register that
it intends to end sales of its Tactical Pilotage Chart, a 1:500,000
map designed to provide worldwide coverage for tactical reconnaissance
missions and Operational Navigation Chart, a 1:1,000,000 map designed
to provide worldwide coverage for high-speed radar navigation.
NGA states that international deals for data sharing require this
change since these products compete with in-country efforts (public
and private) to develop and sell such maps. In addition, there is
mention of increased security, since after October sales will be
limited to Department of Defense players.
The sales policy change has prompted one person to set up NGAMaps.com,
a website to trade CDs of the data in question (almost none has
copyright). The goal is to purchase as many of the $14 CDs as
possible, so that all of the data is available in the civilian
community before it's no longer available. There are no sales at the
website, nor is it a profit making scheme, says its creator. The data
are in ARC Digitized Raster Graphic (ADRG)...

GDAL can do the ADRG conversion to other raster formats:
If this is all true, how to rescue the maps...? Some
sort of FreeGIS server collection might be nice. I found some
TCP maps here
Search engines will know more archives.
Opinions? Worth the efforts?
