My guess is that there are two ways that you might explore to do this. 1. Any time someone says 'statistics', my first thought is 'R'; I don't know any of the things you're talking about here, but if these are statistical methods of some sort, R seems like a valid place to start looking. http://cran.r-project.org/web/packages/rgdal/index.html rgdal will let you read OGR data sources (like PostGIS databases) into a spatial vector object, and interact with them from there. 2. I know that at least some of these mechanisms (like Kriging) are implemented in GRASS, and I would bet that this is your second best option. GRASS is a bit intimidating to a first time user (though I guess not much more so than R :)), but a very powerful geographic data analysis tool.

Re: [OSGeo-Discuss] Staistical analysis support needed
Are you building a desktop or web based application here? I see that you have selected an OpenLayers client, so that suggests web to me. In that case, since you want J2EE technologies, I would suggest Geomajas (which is fully Java - GWT). It has PostGIS support either through GeoTools or through Hibernate Spatial, and can also connect onto a Geoserver (should you still require a web map server). The analysis part would then simply be done server-side using a Java library (JRI?). mayank_agarwal schreef: Hello everyone, Finally I have decided to use Open Layers on client side in conjunction with J2EE Technologies, GeoServer as a web map server and, POST GIS as Spatial Database.

There's also PL/R to access R within PostgreSQL, in case no one else mentioned it. HTH, Yves ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
