    DEM data and height maps

    Below is the links to a tutorial on creating height maps from Digital Elevation Model data (DEM). The tutorial uses Vue 5 infinite and Lightwave together. The tutorial explains the use of lightwave in the very last part.

    Tools used:
    Vue 5 Infinite www.e-onsoftware.com
    Photoshop cs2 www.adobe.com
    Google earth www.google.com (Used to actually get the textures).
    Lightwave www.newtek.com

    Part two-http://www.starssite.com/dem/dem2.mov-50.20mb
    Part three-http://www.starssite.com/dem/dem3.mov-34.26mb
    Part four-http://www.starssite.com/dem/dem4.mov-50.55mb

    All files in zip format can be found at http://www.starssite.com/dem/dem.zip-0.12GB

    Little on the large side but worth it if you need to know this info.

    This is just in case you were creating a game that takes place in an actual area of the world like we are.

    Hope this helps out somebody.

    This is to actually get the data.

    The first thing is you do need to sign up for a free account at http://www.geocomm.com/

    Once you log into your account go here http://data.geocomm.com/dem/

    Click on the link Download DEM data here it takes you to the following link.
    http://data.geocomm.com/dem/demdownload.html

    Once there you should see the map of the united states click on the state you want. For the tutorial I chose Virginia (VA) That then takes you to the following link. Now this is seperated by countywide.
    http://data.geocomm.com/catalog/US/61079/sublist.html

    Now choose your county, in the tutorial I used Norfolk City. That link takes you to the link page so you can choose what type you would like.

    We of course chose Digital Elevation Models (DEM). After choosing that link it should take you to http://data.geocomm.com/catalog/US/6.../group4-3.html

    Then you just choose what area you want, for my example I chose Norfolk South. Click on the normal download.

    It will be in a dem.sdts.tar.gz which can be uncompressed using winrar (you can obtain a free trial copy at http://www.rarlab.com/)

    That file contains the 16 bit ddf files you need.

    ***********
    If your looking for a country try this link http://data.geocomm.com/catalog/index.html

    Choose the letter the country starts with then go from there.

    I hope this helps.

    Hi,

    Anyone know if the above tutorial videos are available elsewhere now? I understand importing the dem data to Vue and exporting will not be a problem but the height data that I'm getting on import isn't correct. What should be a subtle valley is a mountain and I'm not sure how to correct this. I'm hoping that the tutorials would provide some insight.

    Thanks,
    Devin
