Feature #1631
closed
Added by Alexander Watzinger over 2 years ago.
Updated almost 2 years ago.
Description
Currently we are storing geometry data in 3 tables (linestring, point, polygon). We decided to:
- Join all 3 to one table
- Remove the GIS schema and add the new GIS table to the model schema:
UpdateIn the new version we dropped the gis schema and instead added a model.gis table with same fields except that instead having one geom field we now have:
- geom_point
- geom_linestring
- geom_polygon

I started working on it and second Stefan's suggestion to use multiple columns for different geoms (currently: point, linestring and polygon) but will also add a constraint to guarantee that (exactly) one of these columns has to have data in it.

I almost finished merging the GIS tables (branch feature_gis_join), see description for new database structure. It seemed to have been a good idea, besides cleaner code the performance improved a little too.
@ @Stefan Eichert: I would like to test it on THANADOS.
Bernhard is working there on API improvement in the develop branch anyway but I wanted to ask you before merging in develop too in case adaptions on your side (e.g. at the THANADOS database update scripts) are needed.
Could you please test it locally and/or give feedback about that. The GIS merge changes are in the feature_gis_join branch and the install/upgrade/7.3.0.sql is needed when updating.
Also I noticed that in the THANADOS database some gis rows had capitalized names in the "type" field, the update script will take care of these too.
Thanks.

I managed to update the THANADOS code to work with the new table. Locally it seems to work fine. I will do some more extensive testing and get back to you
