Hi Nate and everybody else,

I have a problem (for weeks already) with creating worlds with real DEM (SDTS format).
so this is the way I run gzbuilder:

gzbuilder -i *CATD.DDF -o temp.gzb 
and as I understand gzbuilder would go into other *.DDF files and get the altitudes, slopes, etc.

so gzbuilder creates temp.gzb and then this is my sample temp.world

<gravity>0.0 0.0 -9.8 </gravity>
<utmOffset>0 0</utmOffset>

<xyz>1.637 10.859 3.053</xyz>
<rpy>-0 13 -39</rpy>
<imageSize>640 480</imageSize>


<xyz>0.000 0.000 100.000</xyz>
<ambientColor>0.2, 0.2, 0.2</ambientColor>
<diffuseColor>0.8, 0.8, 0.8 </diffuseColor>
<specularColor>0.2, 0.2, 0.2</specularColor>
<attenuation>1.0, 0.0, 0.00</attenuation>

<color>0.0 0.5 0.0</color>

<xyz>0.000 0.000 -0.000</xyz>
<terrainFile> temp.gzb</terrainFile>

<xyz>0.647 2.267 0.200</xyz>

<xyz>0.0 0.0 0.00</xyz>
<xyz>0 0 0.2</xyz>

<xyz>0.14003 0 - 0.0975</xyz>


But when I run gazebo (wxgazebo)  I always get a big flat flat flat map with nothing on it except robot.
What am I doing wrong?

Thanks for your help.
