Hi,
I am just trying to serve DTED-Data as BIL via Geoserver using an ImageMosaic.
This will enable the Geoserver to deliver whole DTED-datasets as elevation to
WorldWind.
The development process is running well, but actually I am running into the
problem that I have got DTED files with NODATA-Areas (Null) and I want to use
the interpolation capability of the imagemosaic RasterManager. Without
interpolation everything works fine and the NODATA-values are set to -32767.0
(Float32) in the output image. When I am using an interpolation mechanism like
Interpolation.INTERP_BILINEAR or Interpolation INTERP_BICUBIC the output image
contains strange values at the edges of the NODATA areas. How can I exclude the
NODATA values from the interpolation?
Thanks in advance
Tobias
