I am currently engaged in work on a crude space-flight simulation program. At this point the program can depict the earth as seen from particular orbits, utilizing earth surface-feature data from the "Micro World Database" which has been distributed publicly. I would like to have similar data on the moon and planets (at least planets about whose surface features much is known). If anyone on the net has access to this sort of information (legitimately available, I'd be greatly interested). Some parameters follow: (a) I can translate a number of different data formats, but I will eventually want the data in ASCII-readable form, since it will be utilized on both Unix-based and PC-style computers, with significant differences in their binary data formats. (b) I am looking for mappings of surface features such as maria, craters, large-scale mountain ranges, rilles, and the like. (c) The data needs to be indexed according to latitude and longitude coordinates. (d) The data should preferably take the form of l-l coordinates for points to be connected in lines, with some form of code indicating what type of surface features the lines indicate. (e) For my purposes, I need rather low-resolution data. The earth coordinates I use include only continental and island coastlines, and amount to about 2000 l-l points. Large-scale databases would have to be scaled down, and so some form of prioritization of coordinates would be helpful in larger databases. I'd also be interested in knowing if other similar projects are underway (or have been completed). I'll appreciate any help or advice. Ted A.
