Cooper Stevenson" Reply-To: cstevens@gencom.us To: Xconq Mailing List Content-Type: text/plain Organization: General Computer Message-Id: <1095818641.27063.71.camel@localhost> Mime-Version: 1.0 Date: Wed, 22 Sep 2004 02:26:00 -0000 Content-Transfer-Encoding: 7bit X-Virus-Scanned: by amavisd-new at gencom001 X-SW-Source: 2004/txt/msg01215.txt.bz2 Dear All, I have worked on diligently on the GIS side of things. Here's a few quick points: 1) We are not after satellite photos, we are after "Digital Elevation Models." 1a) The entire globe is freely available as a DEM 2) Because the data is in a raster format (as apposed to a regular image file), I believe it is quite possible to automate the creation of new maps and smaller scale views of those maps 3) If you don't have GRASS to manipulate the images (and don't want to fuss with compiling it), don't worry about it: there are live GRASS CD's; just pop on in and boot to GRASS on Linux: http://grass.baylor.edu//demo.html 4) The next Xconq game may take place on Mars. Yes, DEM data available for Mars. 5) If you want to read a good overview article on this, you may find an interesting article entitled, "Global dataset of bathymetry and topography" (PDF) (Not as nerdy as it sounds): http://grass.baylor.edu//newsletter/GRASSNews_vol1.pdf To sum up, I've been like a bull in a china shop, trying anything and everything. I believe I've honed my technique significantly. I hope to have a tutorial and preliminary output soon.
