I am new to use Java and Geoserver.
I have a point sampling location (N,P,K Nutirients value for few fields spanning acroos few acres) on which I want to execute IDW or Natural Neighbourhood Interpolation (Vector To Raster Interpolation) in GEOSERVER and show result on WebMap.
I have done the same thing in ArcGIS using ArcGIS spatial Analysis Tool. Now I have to do the same thing in Geoserver
The Geoserver provide Barnes Surface Interpolation but it does not seems to be suitable for my case since smpling locations are too close.
After searching on Google I understand that Interpolation can be done using GDAL library (GDAL_Grid) by Creating WPS service in geoserver.
I am unable to find proper examples/documentation on How to use GDAL libraries from within GeoServer (I am using Java Platform)
It will be great help for me if anyone can provide pre-requisites of using GDAL libraries with GeoServer and examples of the same.
Also let me know if there is any other way of achieving IDW/ Natural Neighbourhood Interpolation in GeoServer.
