## Prerequisites
|

|
|
|

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

|
|
|
Ubuntu
|
2020-12-21 02:19:11 +00:00
|
|
|
- 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
|
2020-12-21 02:19:11 +00:00
|
|
|
|
|
|
|
|
- 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.
