Re: [Geoserver-users] Contour in geoserver
I think the function should be “ras:contour”, from http://docs.geoserver.org/stable/en/user/styling/sld/extensions/rendering-transform.html#contour-extraction Also, does your data really have values that are this high?

Re: [Geoserver-users] Contour in geoserver
Hi, If I understood correctly ... you should be able to do that. I guess you had a look at GeoServer documentation: http://docs.geoserver.org/stable/en/user/styling/sld/extensions/rendering-transform.html#contour-extraction That say, if possible you should share your current SLD file and the output you currently get.

Re: [Geoserver-users] Contour in geoserver
Hi Gaurav, GeoServer can do interpolation on point data sets on the fly, based on the Barnes Surface algorithm, there is no official documentation but you can read a bit about it here: https://boundlessgeo.com/2012/08/surface-interpolation-in-geoserver/ And then there is a process to extract contour lines from raster data: http://docs.geoserver.org/stable/en/user/styling/sld/extensions/rendering-transform.html#contour-extraction However, we don't have support for going directly from points to contours, and chaining the two rendering transformations above is something that is also not officially supported (we haven't looked into this use case, I'm guessing it's not going to work). The software is open, so maybe you can make changes into it to get chaining rendering trasformations work (if you do, please share back with the community your fixes), or you can have someone do it for you as part of a commercial contract, see here: http://geoserver.org/support Cheers Andrea On Wed, Aug 29, 2018 at 8:18 AM Gaurav Pathak wrote: > We have managed to render the different point values in bands on the > raster map for contouring, however, we are not able to actually create > contours because our point values are not being used to create contour > lines – we had thought this was a feature of geoserver, but increasing > believe that his may be achieved through the gdal library accessed by > Postgre database.

[Geoserver-users] Contour in geoserver
We have managed to render the different point values in bands on the raster map for contouring, however, we are not able to actually create contours because our point values are not being used to create contour lines – we had thought this was a feature of geoserver, but increasing believe that his may be achieved through the gdal library accessed by Postgre database.
