so if you're going to do DEM, cant be stuck in user mode, one at a time.

Code::Blocks project
Command line parameters version and the sorter batch maker script for mirc.
includes Grand Canyon Elevation at spatial res 3 3 1, not 30.
 Example render script

not windows? make your own in C. DIY

thanks for this. I used DEM files (from the usgs) mor than 15 years ago 
iirc. I would need to dig deep for my work, or for what is left of it. 
In time (not soon unfortunately) I shall come back to this.

youre welcome,
found my mistake,

to batch files, seems a good idea to use default bias,
(you cant see min_elev and enter it, as in user mode)

just remove :
  if (hfType == 1) hfBias = atof(argv[5]);
  else

then you always set default bias with only 4 parameters.
doh. my bad. or let me know if you want the upgrade exe.

i got time

if normalizing or not, 4 parameters is default bias
hfBias = -elevBounds[0];

hope to find better resolution.
that one site was the only *available data I could find.
..gov is not working for the people, obviously.

v3 SORTER for Mirc, ungraded more friendly.
no way anyone could easily use v2.
alias goDEMs3 {

the files at webgis say spatial res 30 30 1, seems there is better by comparison
of the two Grand Canyon files,

3 arc seconds 90 meters World-wide SRTM
1 arc second 30 meters DEM from topo, USA SRTM
1/3 arc second 10 meters DEM from topo
1/9 arc second 3.4 meters Newer DEM from LIDAR

included Grand Canyon said,
[15] spatial resolution:   3 3 1

and all that leaves speculation room for spatial speculation.

webgis page says
USGS 1-Degree Native Format - United States

Resolution: ~90 m, 3 arc-sec
Coverage: Contiguous United States, Hawaii and parts of Alaska
Projection: UTM
Datum: WGS 72
Vertical Units: Meter

AND HOW exactly does it explain the file data at 30 30 1
Vs
3 3 1, not seen there, but in gce.dem, included.
