Highlight of the night has to have been seeing the Apenning mountain chain like a wheel spoke out of the Sea of Serenity. On its edge were the crater Archimedes and at the top at 12 o'clock, the large crater Aristotle and the smaller Eudoxus.

I add this to today's image display. Lovely elevation values rules file already available in GRASS.
Tonight's job is to develop the vector layers from VMAP. I shall determine the lat and long values either via the NIMA GEOTRANS software or maybe there is an easier way via a metadata file. Then finally imprt it into my GRASS GIS!
Breaking News! GRASS6.0.1 is out. Priority is to download it onto my PC.
Breaking breaking news! No the binaries for Windows are not yet available! Wait a few days!
Priority for VMAP data is to extract for the bounding rectangle enclosing our region of interest.
The extent values we need to enter into NIMAMUSE are:
in lat long wgs84 coords.
So now we download GEOTRANS from NIMA. 7 megs...takes a while.
Oh bummer coords are in dec degrees. I can't be bothered to convert so we shall live with these. We do not need accuracy at the edges anyway.
So back we go to the VPF Importer. This time equipped with the extents.
Hydrography - rivers and lakes are done.
Physiography - ice fields - useful.
As of tonight all data layers are in the GIS.

This is a zoom of the data I am working on at the moment. The full dataset I show also on the page for today. You can see clearly Starnberger Lake, Ammersee , Tegernsee and Schliersee.
Thanks are due to the Global Land Cover Facility for this source data.

I immediately dived into NVIZ as most GIS people who love 3d would do only to find fault in the quality of the DEM used in this case - it has stepped patterning in it and I need to research why. Ah well at least we are now in the GIS realm not just figuring how to import this stuff.
So to recap all VMAP, SRTM and Land´sat data are now downloaded and on my PC in a format useable by GRASS.
