3.4 is the tightest there is, according to google,
of course I dont see any data there. that 3-letter word again.

final DEMPOV.exe output is interesting,
4 parameters 0 1 1 0, using default bias,
might be correct usage.
file gce.tga
1442401 pixels were written to the file.
For converted data points:
MinValue = 0.000 MaxValue = 65535.000
but do the heights align, yet to be tested.
0 0 15 0,
used in previous renders, heights aligned.
with a hefty block underneath.
need more test renders.
all i got so far.

Niagra county,
only 6,
not normalized,
bias of 0, aligned heights better than default bias.
but Gasport was way off
fine tuned ...
path %PATH%;c:\ftp\dempov\bin
DEMPOV akron.dem akron.tga 0 0 4.5 0 0
DEMPOV barker.dem barker.tga 0 0 5 0 0
DEMPOV gasport.dem gasport.tga 0 0 16 0 0
DEMPOV lyndonville.dem lyndonville.tga 0 0 5 0 0
DEMPOV medina.dem medina.tga 0 0 4.6 0 0
DEMPOV wolcottsville.dem wolcottsville.tga 0 0 4.6 0 0
got enough options,
just depends on the data you have, apparently.
Shasta county and Mount Shasta were 0 0 15 0

and for the user friendly stuff, add this,
alias deminit {
%parameters = 0 0 15 0
%WorkingDir = c:\ftp\dempov\bin
%proj = untitled
; if (!init) program uses defaults
}
menu status {
-
DEM Initialize: deminit
}
added project title, which is set with a filename if you dont.
title*.bat files makes more sense.

thanks if it has DEM files. would be cool.
probably should have waited another a week to post, it's never done.
with bulletproof defaults, it wont error.
reading the program answers all questions.
post any changes to main.c or dems*.mrc -
if two heads aren't better than one, everything is doomed for sure.
Current issue in main.c is a 2-4 degree rotated image, for some DEMs.
