Holes in DEMs

[João Fonte]

Hi Martin,

I'm getting these holes in some DEMs after using blast2dem, I suppose it is because of low point spacing in these areas, but is there any way to correct them?

Thanks!

Cheers,

Joao

Hello Joao,

Indeed. Overly large triangles are not rasterized into the DEM. The default kills all triangles with an edge length of 100 or larger. You can change this by adding the option '-kill 500' to the command line. Then only triangles with an edge length of 500 or larger will be killed.
