How to make/create a .hdr file from a dem file?

[Guest]

Hi!I got a .dem file covering my hometown. To use it in Terrascene I have to use GTOPO30 to generate a .RAS file. After I have used the FileConverter I only have a .rev file, but DemFileViever also reguire a .hdr file? Where/how do I get/generate it?I have been reading http://www.fsnordic.net/article/article/terrascene2/ts2.phpIvar

Are you using the right version of GTOP30? There is one version for GTOPO30 and one for DTED-0. Using the right version, you should get both the .rev and .hdr (and more) files.

It may be very hard to find. Send me a mail, and you`ll get it.BTW There is really not much help in DTED-0. It has the same faults deep in the fjord areas (GTOPO30 is derived from DTED-0), and GTOPO30 has much better valleys. Personally I have left DTED-0 for good, waiting for the new SRTM data. Meanwhile I use GTOPO30, which gives a vast improvement compared to the default data...
