Description
As discussed in the proj bug tracker a while ago (http://trac.osgeo.org/proj/ticket/47), there was a problem with the definition of datum transformation parameters for EPSG 31370 in the proj epsg file.
The same issue is still present in QGIS' srs.db, leading to a slight offset of 10-20m. Running:
update tbl_srs set parameters='+proj=lcc +lat_1=51.16666723333333 +lat_2=49.8333339 +lat_0=90 +lon_0=4.367486666666666 +x_0=150000.013 +y_0=5400088.438 +ellps=intl +towgs84=-106.869,52.2978,-103.724,0.33657,-0.456955,1.84218,1 +units=m +no_defs' where srid='31370';
Solves the problem for me.

- Resolution set to upstream
- Status changed from Open to Closed
This should be solved upstream, not in QGIS DB, which is simply a copy of the original one.
