[SOLVED] Artifacts in terrain
Reply with quote

Hello,

i'm creating terrains using USGS tiles 256x265 pixel at 5 meter/pixel, and NED1 (30 meter/pixel).
The following image is part of a 40km x 40km terrain of Mount St. Helens, and shows artifacts at the level 4 (the maximum level)

The problem is with lighting on (a problems of "normals"?).
Any hint?

Thanks

[EDIT]
well, i found the problem is gdalwarp. I convert the NED1 to epsg 3857,
but the conversion is terrible. I'm going on looking for the solution.

[SOLVED]
I must use a good interpolator using gdalwarp on NEDs. The default "near" is not enough.
