Feature #1631

Updated by Alexander Watzinger about 2 years ago

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: schema 

 In the new version Only issue to solve would be how we dropped differentiate between areas used when the gis schema exact extend is known and instead added a model.gis table with same fields except areas used when it is known that instead having one geom field we now have: 
 * geom_point 
 * geom_linestring 
 * geom_polygon 
 the extend is (somewhere) within.
