Hi, OpenJUMP is pretty dumb with projections. It does not interpret the projection of the PostGIS tables and layers which are read from the database get the default projection code -1 in OpenJUMP. You can set the SRID with the "Set SRID" tool (until today "Change SRID").
What are experiencing two different things. First is that when you read your new SRID=31467 layer back into OpenJUMP it is without projection until you use the Set SRID tool. Another thing is that projection "-1" means the default projection. However, the default projection code used to be -1 in PostGIS up till version 1.5, but in version 2.0 it was changed to zero "0" which means "Unknown geographic projection". I think OpenJUMP has a bug in this place because it is not possible to save a new table into PostGIS with SRID=-1 which still exists but has nowadays a special meaning "Unknown Cartesian projection". In your use case just remember to use Set SRID always before saving the new layer into PostGIS. Michaël can tell more, I suppose that OJ must be somehow aware of the layer SRID when PostGIS tables are updated. -Jukka Rahkonen- Uwe Dalluege wrote: > Hi, > > if you load a PostGIS table with an srid value and you save this layer again > to > PostGIS the srid is lost (0). > > 1.
