[gdal-dev] polygon to grid?

[Lewis, Ambrose J.]

Hi All:

I'm relatively new to GDAL/OGR, so please forgive a dumb question!

I have a grid file (DTED elevations) and a shapefile of polygons
(building locations and an APEX attribute representing their height).

I'd like to combine these together so that my new[x,y] = DTED
elevation[x,y] + building apex[x,y] (assuming the building apex is zero
if the loc was outside any of the shapefile's polygon)

How can I convert the polygons to a grid compatible with DTED?

THANXS!

amb
