Spatial database set up

Supporting installation of spatial data into Postgres DBMS.

  1. Install Postgres

To install Postgres from scratch please ref to Postgres installation. For simplicity, use .pgpass file to avoid supplying the password every time as decribed in Passwordless configuration.

After installation, Make sure you have the paths to these tools added to your system’s PATHS.

Note: Older version of this raster2pgsql was a python script that you had to download and manually include in Postgres’s directory. Please consult an operating system expert for help on how to change or add the PATH variables.

For example, this could be a sample of paths exported on Mac:

#~/.bash_profile file, Postgres PATHS and tools .
export PATH="/Applications/${PATH}"
export PATH="$PATH:/Applications/"
  1. Enable PostGIS extensions
If you have Postgres set up, enable PostGIS extensions. This is done by using either Postgres CLI or GUI(PgAdmin) and run For psql CLI
psql -d yourdatabase -c "CREATE EXTENSION postgis;"
psql -d yourdatabase -c "CREATE EXTENSION postgis_topology;"

**For GUI(PgAdmin)**
`CREATE EXTENSION postgis_topology`

For more details refer to the Postgis docs.
