Is there a driver to import USGS DEMs (non SDTS)?

[Aleksey]

Hi,

I am trying to use GDAL to import a USGS DEM data set (into GRASS using the 
r.in.gdal module). The datasets are 10-meter New York State DEMs available 
from the Cornell University CUGIR site 
(http://cugir.mannlib.cornell.edu/index.html; Go to "Search CUGIR data" and 
enter "DEM").

As I can see from their metadata (available at the same site), the datasets 
are not in SDTS, but rather in USGS ASCII format with the header record 
(A-record), followed by a series of profile records (B-records), and an 
accuracy record (C-record). The format seems to be (an older?) standard to 
USGS, it's documented at: http://rockyweb.cr.usgs.gov/nmpstds/demstds.html 
(part2).

Is there a way to read in such datasets with GDAL? In the GDAL tree (version 
1.1.5, built on Linux) I see frmts/usgsdem, but it is empty. Any 
suggestions/ideas?

Thank you

Aleksey
