# Sonoma County Building/Parcel/Address Import

`original_data` from:
2020-12-20 06:31:53 +00:00
- https://gis-sonomacounty.hub.arcgis.com/datasets/2202c1cd6708441f987ca5552f2d9659

Overpass query (you may save as OSM file, shapefile, or postgres sql dump depending on your overpass client)
2020-12-20 06:31:53 +00:00
```
area[name="Sonoma County"];
2021-01-14 06:47:55 +00:00
(
way[building](area);
relation[building](area);
);
2020-12-20 06:31:53 +00:00
(._;>;);
out;
```

If using an Overpass -> QGIS -> Postgres dump, save it as `osmquery_buildings_pgdump.sql` for later.
Otherwise osm2pgsql should create tables like `son_polygon` for later.

## Prerequisites
2020-12-21 02:19:11 +00:00
The postgis package appropriate for the version of postgres server you have installed (in my case, 11)
2020-12-20 06:31:53 +00:00
Ubuntu
2021-01-14 06:47:55 +00:00
- sudo apt install postgresql-11 postgresql-11-postgis-3 shp2pgsql osm2pgsql
Debian (shp2pgsql is included in postgis)
- sudo apt install postgresql postgis osm2pgsql
- The postgresql server started/running/configured and database `gis` created
2020-12-20 06:31:53 +00:00
## Running
2020-12-21 02:19:11 +00:00
2021-01-14 06:47:55 +00:00
- Run the following SQL as a superuser (postgres) inside the `gis` database to enable the PostGIS and hstore extensions: `CREATE EXTENSION postgis; CREATE EXTENSION hstore;`
2020-12-21 02:19:11 +00:00
- Unzip the `original_data` and open a shell in that folder.
2021-01-14 06:47:55 +00:00
- Here we are assuming that county data is in WGS84/EPSG4236 format, which was true as of last check and is also what OSM uses.
- Run from your shell: `shp2pgsql -s 4326 -I Parcels__Public_.shp | psql -d gis -U postgres -W`
- `shp2pgsql -s 4326 -I Sonoma_County_Building_Outlines.shp | psql -d gis -U postgres -W`
- `shp2pgsql -s 4326 -I osm-buildings-01-03.shp | psql -d gis -U postgres -W`
2020-12-21 02:19:11 +00:00
Now all the data is in Postgres. For processing and conflation, read through and execute `conflation.sql` as per your comfort level.
