Hi All,
I have a point sampling location on which I want to execute IDW
Interpolation. Regarding this I have number of questions as follows -
a) Is there any process available for IDW interpolation (Available in
ArcGIS) in Geoserver.
Not that I know of, but there is a point interpolator called "Barnes
Surfaces"
that should do a better job than IDW for slowly varying data (e.g.,
metereological data).
While available in GeoServer, it's unfortunately not documented in the
official docs, but Boundless
has a page describing it here:
http://suite.opengeo.org/docs/latest/cartography/rt/barnes.html
b) If not present how can I write my own function in Geoserver.
Yes. The barnes surfaces could serve as an example:
https://github.com/geotools/geotools/blob/master/modules/unsupported/process-feature/src/main/java/org/geotools/process/vector/BarnesSurfaceProcess.java
c) How to use R function in Geoserver.
We do not have direct bindings for R, but they could be written by creating
a ProcessFactory
(not trivial, but powerful, a properly done one would allow to use most R
spatial capabilities).
Cheers
Andrea
