No description provided.

Where can I see the data in dev?

[Alexdavv]

In dev_osm schema

[pavgra]

What about polygons for the areas? Will there be a coupled CSV / any other data file with concept_id / concept code and geom pairs?

@pavgra Sure, concept_code + geometry is already in the used source and csv may be exported now. Once vocabulary is released, the concept_id + geometry pairs will be available as well.

The reason I'm asking:

• I do not see where geom field is persisted into resulting (stage?) table
• not sure how that would be processed via Athena, we haven't discussed any solutions yet

[Alexdavv]

It's non needed there now since CDM is not ready for storing the geom data.

Ok, good. We`re ready to discuss with Athena developers.

It's non needed there now since CDM is not ready for storing the geom data.

From what I recap (OHDSI/CommonDataModel#220 (comment)), it was decided not to store any binary data (polygons) in CDM. Plus, the data is required for separate apps / ETL, not for the CDM itself (the CDM itself will contain precomputed links and relations of entities from medical to geo domains). Therefore, not sure what you are waiting for.

[cgreich]

Not sure what you guys are debating. Now that we have the hierarchy of geographical concepts, we can assign to each a set of polygon information. Whether that's distributed through Athena or not is a different question. Looks like they are already available, so I would start with those. If Athena were to deliver them we'd have to go through the CDM WG ratification process and create new tables.

@cgreich , how do I get polygon for a concept set from the vocabulary introduced by the PR?

[cgreich]

Right now informally. The team will publish them as a CSV file somewhere on the OHDSI website or here.

[pavgra]

Great. And this will be repeated for each release? (manual publishing of the CSV)

[cgreich]

Correct, until we add it to the CDM.

[hardhouse]

also need readme.md

@cgreich @pavgra. Done and available here: ftp://ftp.ohdsi.org/geography/geometry.csv
DDL (Postgres):

CREATE TABLE geometry
(	concept_id int,
	geom geometry(MultiPolygon,4326)
);
