Yes there is a standard, Check with the USGS http://edcnts12.cr.usgs.gov/ned/default.htm Here's a dataset for Grand Teton National Park. http://edcnts12.cr.usgs.gov/ned/samples/teton.htm The data maps used to be free, but now it looks like the government is going to charge us to access the work we payed for in the first place. DED, DEM, NED are some of the acronyms I've come across. Once you start researching however you'll find all diferent kinds of mapping data available. -----Original Message----- From: Helmuth Trefftz [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 11, 2000 11:57 AM To: [EMAIL PROTECTED] Subject: [JAVA3D] Terrain elevation Hi, We need to build a 3D terrain representation for a demo. Does anybody know of a -- hopefully non-classified -- standard to represent elevation on maps? Has somebody built a reader/renderer for such standard? Any hints/suggestions/sample-code are most welcome. Thanks. ------------------------------------------------------- Helmuth Trefftz Rutgers University e-mail: [EMAIL PROTECTED] tel: (732) 445 0542 fax: (732) 445 4775 fax: (435) 604 9354 ------------------------------------------------------- =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
