[Geoserver-devel] WPS with R module

GeoServer GeoServer Developer
1

Hi,

I’d like to create a new community module called wps-r. The purpose is to run R processes from GeoServer.

I have done a prototype and my plan seems to go well. Before I get in too deep, I thought I should get an approval and commit my code.

The plan is to:

  1. Create wps-r community module.

  2. Add a profile (-Pwps-r) in wps-core pom.xml to include wps-r module as a dependency if enabled.

The implementation details:

Cheers

Rini

The implementation details:

- Create a catalog file from R help files (*.Rd files) to load base
functions automatically. The catalog can be edited with custom processes.

- Use RServe to call R from my module.

- I followed this guide for the rest of it:
http://docs.geoserver.org/latest/en/developer/programming-guide/wps/index.html#the-processes

Nice!

Wondering, on trunk most of the processes that have nothing to do with GeoServer
internals are in Geotools.
Wondering if using r-serve forces a GPL license on the code though?

I'm also curious about the integration between feature collections and
R spatial abilities,
how is it going to happen?

Btw, this might be of interest:

It no longer does an API - and instead uses client / server. I know a
team using R and uDig in this fashion.

Hum, there seems to be a client library, but now that I look into the
sources the
src/client/java-new has the following LICENSE file:

So it seems that using this one it should be possible to put the work
in Geotools

Thanks Andrea. I am using REngine indeed.
This document says GPL-2 though (http://cran.r-project.org/web/packages/CommonJavaJars/CommonJavaJars.pdf):

I better clarify with them first and then I'll get back to you.
