What information does your shapefile contain, elevation points? If so, and if they are regularly spaced, you can probably use the GMT utility xyz2grd, <a href="http://gmt.soest.hawaii.edu/gmt/doc/gmt/html/man/xyz2grd.html">http://gmt.soest.hawaii.edu/gmt/doc/gmt/html/man/xyz2grd.html</a>. Otherwise you will need to interpolate the points into a regular grid, and my only experience doing this is with ArcGIS's Spatial Analyst. I would imagine GRASS has similar capability though. I'd be curious to hear other suggestions as well.<br>

<br>Hi,<br>
<br>
Thanks for the quick answers. <br>
<br>
Do you know how can I convert a shapefile to a suitable format for those apps (either rel.py or DEM utilities)? I've searched the documentation, but I didn't find that info.<br>
<br>
Thanks,<br>
<br>
