original_data from:

• https://gis-sonomacounty.hub.arcgis.com/datasets/2202c1cd6708441f987ca5552f2d9659
• https://gis-sonomacounty.hub.arcgis.com/datasets/0f5982c3582d4de0b811e68d7f0bff8f

/*added by auto repair*/
(._;>;);
/*end of auto repair*/
out;

Prerequisites

The postgis package appropriate for the version of postgres server you have installed (in my case, 11)

Ubuntu

• sudo apt install shp2pgsql osm2pgsql
• sudo apt install postgresql-11 postgresql-11-postgis-3
• The postgresql server started/running/configured and databases gis and osm created

Running

• Run the following SQL inside the gis database to enable the PostGIS and hstore extensions: CREATE EXTENSION postgis; CREATE EXTENSION hstore;
• Unzip the original_data and open a shell in that folder.
• Then, run from your shell: shp2pgsql -s 3735:4326 -g geom -I Parcels__Public_.shp | psql -d gis -U postgres -W
• shp2pgsql -s 3735:4326 -g geom -I Sonoma_County_Building_Outlines.shp | psql -d gis -U postgres -W
• osm2pgsql -d gis -c --prefix son --slim --extra-attributes --hstore --latlong sonoma-orig-buildings-20201219.osm -U postgres -W

Now all the data is in Postgres. For processing and conflation, read through and execute conflation.sql as per your comfort level.
