Follow-up from "Added the obm_completeness_assessments table": Replace the `built_area_size` field with an on-the-fly computation of the area size
The following discussion from !12 (merged) should be addressed:
Can this be computed on the fly by the database to save storage?
For the computation, a projection of the building geometry to the Albers Equal Area projection is necessary. All necessary function for this are already built in PostGIS.
My suggestion is to create a view with such an on-the-fly field and measure the performace compared to directly accessing the pre-computed field.
