Questions to ask here

  • The codes for residuals, mapinfo, picinfo
  • Does having landmarks with only 1 or no images mess things up?
  • Bigmap - what does Map overlap mean
  • No fit. Below height correlation limit

done

*What is the math for the resolution and scale parameters. -- 50 meters + 25% -- The footprint width of the XXXXXX.IN files is resolution * #pixels * 360 / (2 Pi cos (latitude) Radius )

*How do I increase the resolution of a big map (aka do more processing), especially how to remove bands -- fill, does better resolution -- Notes in Dropbox/Avatars -- make a big map, take all maplets that are enclosed (inside.txt) replace all of their height info from bigmap. Then take all of the maps (usedmaps.txt), then do a complete iteration.

*Have you uploaded the LAMO images yet? *Can you upload your new maplets/landmarks (via rsync if possible)

*Any more work on Tislovsky? (better than 5 meter)

*What is a good way to output a DEM in the form of a DEM (png, binary, ascii)

1/64th works out into 68 meters and higher at higher latitudes S. Pole map is at 25 meter resolution

SpheremapB - DTEM and shaded relief -- raw and pgm, 16bit unsigned short (which is in the header) -- takes bigmaps and makes a large map (either orthograthic, stereo, equrect) option C, equatrangular

mGrav - makes elevation map relative to gravity slope, gravity, acceleration, elevation
