Something interesting for route builders

Hi guys, I have something interesting for route builders 8) but theres a catch to it. I found 90 meter dem data for free that you can download directly though Google Earth "I'm not sure if you have heard of it" but it might be very useful if you can work out a way to get DEMEX to read the dem data or convert it so that DEMEX can read the data to use it within your route designs Wink

First: Check out http://srtm.csi.cgiar.org/ and download the "srtm41.KML" file from "http://www.ambiotek.com/topoview". Open up the KML file in Google Earth and you will see little mountain icons and you can click on them to get the 90 meter dem data downloads for free Very Happy As for converting the files to read in DEMEX I honestly cannot work out how to get this done but the terrain data is hell alot better from the preview in Google Earth which shows cuttings, embankments etc... 8)

"If you can find a program that can convert the dem data to read in DEMEX please let me know Wink "

Best Regards, Phil

Here is what I did
After unzipping the srtm file I got 4 files
One (1) was a tif file
OPEN the tif file with the old ….3 DEM program
Go…..File….Load terrain model…..Geo tif DEM (tif)
And load the tif file
Let it do it’s thing and it should give you a map

Now go …..File…..Save GeoTiff DEM
Give it another name , I named it “test”
You will be asked to save as GeoTiff DEM, click OK
Give it a name and Save

Close 3 DEM

OPEN DEMEX
Load your route
Load your NEWLY NAMED  tif file
Once loaded your route should be within the shaded area

This is as far as I went
Someone can see if it goes any further as I didn’t want to destroy an already DEMEXed route

Actually I found the .hgt files Demex wants in
http://mirror.ufs.ac.za/datasets/SRTM3/Australia/
Had to go to SSTRM2 version for S38E143 because it is faulty in STRM3.

Great idea and sounds like it saves a lot of time. I will look in to it for the next project I am in
