I guess you are getting an empty image because you have not told gdal
which field includes the height data. I was successful with
gdal_rasterize -a HAEDDYPIME -ts 5000 3000 -l is50v_haedarlinur_24122013

You are right that the .ige file is not supported, but take the .img and
you get the DEM data
I'm installing qgis right now to try, hopefully it's not too
complicated.
I think haedarpunkar is just mountain peaks, not full details providing
the contour like the polygons are - when I rendered it out with
gdal_rasterize the points were very sparse. I know nothing about the
internal details o
Karen,
What is the field with the elevations? I tried with HAEDDYPIME:
gdal_grid -of GTiff -l is50v_haedarpunktar_24122013 -outsize 1000 1000
-zfield HAEDDYPIME is50v_haedarpunktar_24122013.shp x.tiff
Grid data type is "Float64"
Grid size = (1000 1000).
Corner coordinates = (248491.242441 674
The problem exists when I output straight to a PNM as well, not just
with geotiff.
Can you give me an example gdal_grid command which actually works to
create a heightmap image that your average program can read? Because I'm
getting nowhere. :( For example, as a test:
gdal_grid -ot Byte -of PNM -

Karen,
For example this command on my computer
gdal_rasterize -burn 1 -l is50v_mannvirki_flakar_24122013 -of GTiff -ts
1000 1000 is50v_mannvirki_flakar_24122013.shp x.tiff
produces a 1000 x 1000 geotiff which is mostly zeros except ones where
the polygons are.
Can you tell us what command
Hi all,
I'm running Fedora 21 with a fresh built gdal-1.9.2. Try as I might, I
can't get gdal_rasterize to output anything other than purely
transparent images, purely white images, or purely black images.
I want to use it on this dataset - "Elevation data. GDB og SHP.
ISN2004":
