Hi, I am using HGT data to serve raster elevation tiles. My aim is to serve smooth over-sampled raster thanks to BarnesSurface transform.
Why BarnesSurfaces? I've tried to set "Publishing > Interpolation Methods > Default Interpolation Method" at layer level to bilinear or bicubic but this parameter seams to be always ignored. So I tried to set "Raster Rendering Options > Default Interpolation" at WMS level to bilinear or bicubic but this generate interpolation grid artifacts as you can see: <http://osgeo-org.1560.x6.nabble.com/file/n5067021/bicubic_artifacts.png> And this is without considering the fact that it is not an acceptable solution for me to set interpolation method on all WMS layers to bilinear/bicubic. (By the way if someone knows a workaround to achieve that, please share it!) So last chance for me to reach my goal is to use Barnes surface in order to interpolate fixed resolution elevation data to a beautiful smooth surface. Or if you can see another alternative, I will appreciate every suggestion. The problem is that I can't make working my BarnesSurface transform SLD with my layer of elevation data. What I've done: - Create an ImageMosaic store with some HGT files. - Create an SLD style. - Publish a layer from this store with this style. I use last GeoServer 2.3.3 stable release. The style I use (found in another post): When I try to render my layer I get this error in GeoServer log: geoserver.log <http://osgeo-org.1560.x6.nabble.com/file/n5067021/geoserver.log> In short: Am I right to set "valueAttr" to GRAY_INDEX for HGT layer? I can't figure out my mistake, there is not so much resources about Barnes surface. Can someone help?
