[GRASSLIST:9856] accurate DEM

[orkun]

hello

Slope angle map is critical issue for my study. Hence I need to
generate a DEM that represents the terrain accuratelly.

So, I want to know:
compared to TIN, what are the advanatages and disadvanatages of
spline tension interpolation.

I use 1/25000 scale digital contour map as the base map.


regards

Ahmet Temiz
