They have several publications on map projections, one called "Map Projections - A Working Manual (Paper 1395)" and there is another called something like 'The Atlas of Map Projections'. I have the first publication and it contains many formulas and specs. The second publication is basically what it says and contains many many projections. Check with the USGS (I'm sure you can find a telephone number or an order number, after all it is the government) or try a University library. My University has a government publications area that contains all the USGS publications, but I doubt that your typical public library would have the books. Anyway, I'v found all the information I need about the projections for the USGS, now as to display, this is of course a much more interesting problem . . . ..Mike Figueroa.......................... _______________________ . 6600phnx@ucsbuxa.ucsb.edu (Internet) . / // / . @ucsbuxa.bitnet (Bitnet) . /---- // / __ ......................................... / // / / "Vila weights 73 kilos . . ." / ------ ------
