Stepped Terrain on Low Elevation Zooming

[vistacon21]

Hi, I'm using your library with the following dataset and config geoserver config

Geoserver plugins: BIL/DDS, image pyramid

Source Data: dted level 2

Dted2 Conversion Steps:

• gdalbuildvrt dted2.vrt .//.dt2
• gdal_retile.py -v -r cubic -levels 4 -ps 512 512 -co "TILED=YES" -targetDir dted2-tiles dted2.vrt

Elevation data store: Image Pyramid

BIL Format Settings

• Application Encoding: application/bil16
• Byte Order: Big Endian

The terrain renders, but on close-in zoom levels, the terrain appears to have a "stepped" appearance. Do you know if there's anything I can do in the conversion process or otherwise to generate the terrain so it doesn't have the stepped appearance on lower elevation zooming?

Hello did you test with dted 3. dted 2 has a precision of 30 meters so could you test with a more precise dataset?
