putting this back on the list.. just asking because Jukka asked for SRID support for JML https://sourceforge.net/p/jump-pilot/mailman/message/36133057/
we negotiated a plain GML2 solution via a bounding box. now i am engineering a way to route the layers SRID style value to the file writer, which traditionally only receive the feature collection. how'd you transfer this and possibly other informations to the legacy writers? ..ede On 11/28/2017 23:10, Michaël Michaud wrote: > Ede, > > Just had a look into WritableDataStoreDataSource code. > > Generally, it uses the srid defined in the DataSource properties to write > geometries to PostGIS. > > There is a single corner case where a second geometry is stored into an > attribute of type Object, in which case, it will try to use the embeded > Geometry SRID. > > This corner case could probably be ignored if there was a real interest to > let a default 0 value in Geometry SRID. > > I still must check the old PostGIS writer... > > Michaël > > > Le 28/11/2017 à 21:43, Edgar Soldin a écrit : >> On 11/28/2017 20:52, Michaël Michaud wrote: >>> Hi, >>> >>> >>>>> Hi Ede, >>>>> >>>>> I just realize that I haven't received message posted to jump-pilot-devel >>>>> for months (beginning of august I think) >>>> ok, what about the issue "setting SRID"? any comment? >>> I'm not sure.
