Does anyone have altitude data for some world patch? I'm looking for something like a one-mile grid of altitudes to try out various 3D graphics. Any pointers welcome, thanks!

If we could just get everyone to resubmit UUCP map entries with accurately measured altitudes as well as lat/long, you'd have a great database to play with... :-) jjc -- john j. chew (v3.0) poslfit@gpu.utcs.toronto.edu +1 416 463 5403 (300/1200 bps) poslfit@utorgpu.bitnet {cbosgd,decvax,mnetor,utai,utcsri,{allegra,linus}!utzoo}!utgpu!poslfit "Script-G for open, sub-delta for durchschnitt"

I'm assuming the information is still accurate, but possibly not. ---------------- From cmcl2!seismo!lll-crg!mordor!sri-spam!nike!ucbcad!ucbvax!MIMSY.UMD.EDU!furuta Wed Aug 13 16:16:13 EDT 1986 Article 492 of mod.computers.laser-printers: Relay-Version: version B 2.10.2 9/18/84; site phri.UUCP Path: phri!cmcl2!seismo!lll-crg!mordor!sri-spam!nike!ucbcad!ucbvax!MIMSY.UMD.EDU!furuta >From: furuta@MIMSY.UMD.EDU (Richard Furuta) Newsgroups: mod.computers.laser-printers Subject: [lesk@petrus.arpa: maps] Message-ID: <8608112117.AA12914@mimsy.umd.edu> Date: 11 Aug 86 21:17:47 GMT Article-I.D.: mimsy.8608112117.AA12914 Posted: Mon Aug 11 17:17:47 1986 Date-Received: 12 Aug 86 22:43:21 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The ARPA Internet Lines: 38 Approved: laser-lovers@washington.arpa The following message may be of interest to those of you looking for map data. --Rick Date: Sat, 9 Aug 86 21:55:11 edt >From: lesk@petrus.arpa (Michael Lesk) To: amsler@petrus.arpa, reid@decwrl.dec.com, furuta@washington.arpa Subject: maps Street maps of all US cities are available from the U. S. Census Bureau, Data Users Services Division. Call 301-763-4100 and ask about GBF/DIME files. Typically a single SMSA (Standard Metropolitan Statistical Area) fits on a tape and costs about $135. The U. S. Geological Survey provides Digital Terrain Models (digitized versions of the 1:250 000 series, altitude given at grid points); a 1:2 000 000 vector map of the whole USA, plus more detailed maps of a very few areas: call the U. S. Geological Survey, 703-860-6336. The CIA has a map of the whole world, outlines only. It is sold as World Data Bank II, from the National Technical Information Service. The ordering numbers are: N. America PB 271 868, S. America PB 271 870, Europe PB 271 871, Africa PB 271 872, Asia PB 271 873. Your local library will be quite familiar with procedures for ordering from NTIS. Among foreign countries, at least Great Britain has some map information in machine-readable form. I have not checked any other countires. There are major changes coming in machine-readable maps for the 1990 Census -- but I don't believe the new data is available to the public yet. The Defense Mapping Agency also has data, not always available to the public (usually the USGS serves as their agent for civilian sales). Let me know if this is not sufficiently responsive to your request. Also, I have not called some of those phone numbers in a year or two -- let me know if they have changed or you have trouble reaching them.
