What this is about is to have settlement data (stored in
obm_completeness_assessments
) to be compared and assess its completeness with the state of the tile which is given by the OBM/OSM built area. So having OBM/OSM built areas inobm_completeness_assessments
doesn't make sense to me and would feel like compare OBM to itself.When I said OpenStreetMap above, I referred to
OBM Buildings
, as this is where the data is coming from, and I wasn't suggesting to compare OSM withOBM Buildings
. Agreed that this wouldn't make sense at all.Datasets saved in
obm_completeness_assessments
can be compared the same way if they are in the other table. By adding it to theobm_tiles
we just narrow down a lot of good flexibility that we could well need later on and we build a more monolithic system that will be harder to manage.Besides the increased flexibility and following a recommended modular approach, I think it would be nicer for visualization purposes, too, having the OBM built area size data in the
obm_completeness_assessments
table, as we could use the same style and tool to visualize all kind of datasets that are being added.Edited by Felix DelattreI understand better now. Then, I think we can transform this new field into a
source_id == 0
inobm_completeness_assessments
and do the calculations comparing other sources withsource 0
. What do you think?Edited by Nicolas Garcia Ospina@ds What is your opinion about having the OBM built areas to be another source in
obm_completeness_assessments
instead of having it inobm_tiles
?@nicgar: I always thought they should be in
obm_completeness
_assessmentas a source for any further assessment. However, as discussed initially,
obm_tilesshould reflect our best knowledge about the tile, i.e. built area and its completeness (being manual or automatic, whatever is the best estimate). Either we have the polygon of built area in
obm_tilesor we refer to it in the
obm_completeness_assessmentor in
obm_sources`. I really don't care where the data is stored as long we can easily disseminate and use the best available information per tile.
