I need to save my vectors layer back to PostGIS, which if I read correctly I can do using GeoServer, however I'm confused. All the examples ask you to import a shapefile. I don't have a shapefile. This will be a empty vector layer on top of a couple of base layers which the user will add polygons, points etc. etc.

How do I create the tables to hold the vector data. Also how do I know the structure of the tables. e.g columns, column names, primary / foreign key, relationships etc. etc.

You can add empty tables to PostGIS in Geoserver:

Before this view can be served by GeoServer, the following step is necessary to manually create the geometry_columns entry:

INSERT INTO geometry_columns VALUES ('','public','my_view','my_geom', 2, 4326, 'POINT' );

  • Hi @Mapperz. I added the values above into the relevant geometry_columns table but when i go to add a new layer from my data store the entry is not available. any ideas Apr 26, 2011 at 14:54
  • did you CREATE TABLE them, too? The example above implies my_view has a point geometry field called my_geom Apr 26, 2011 at 17:06
