Anyone know of a free global vector elevation contour dataset. Have processed DEM to contour but the generalisation is proving challenging. There is VMap0 but that is imperial rather than metric.

Thanks in advanced

Thanks Greg for reply. Unless I missed something that is a DEM which I have already. Was looking for vectors for scales around 1:40M scale, but possibly its not available as vector dataset.

I think you will be hard pressed to find global DEM coverage in vector format. You might try the recently released Jaxa ALOS world DEM at 30m and try contouring that. It is available here: http://www.eorc.jaxa...ALOS/en/aw3d30/

 

Cheers,

Yep thought it was a long shot. I'll have to work on improving generalisation of contours derived from DEM raster.
