Ok for file based formats, but your hint was to move form other
databases to spatialite... Anyway, Spatialite is great ;)

Portability, offline access. No database server.
Simple shapefiles or simple dbf for R analysis? = Pain.

Hi Bob,
thanks for the feed back.
Do you capture groundwater level data in boreholes and in monitoring wells with
this plugin to store it in a database? Sounds interesting although I wasn't
searching exactly for that.
Want to process data of existing groundwater databases with QGIS. Processing
Spatial interpolation can be realized in many ways. There are lot
different methods, which fit different needs.
- Inverse Distance Weighting (IDW)
- B-Splines
- Kriging
- Statistical simulations
- etc.
As you know, none of them is correct without a knowledge of the
groundwater structure and
AFAIK, QGis can do IDW [1], while the other methods will need external
softwares like GRASS and R. In this case the related QGis plugins can
be used.
Kriging can be done in QGIS with the SDA4PP plugin (trough R).
cheers

Hi Christine,
Is your current data is in database system now? Getting a subset of
your database from your current database system (e.g. Oracle, MS SQL,
etc.) to Spatialite database which can be easily accesses by R, Grass
and R Geospatial for analysis. Spatialite is supported in R package a
