Examples

The web map examples in this section are set up to render a basemap layer from Wikimedia and vector tiles from pg_tileserver running on a local machine, using popular open source JavaScript web map components.

Load Natural Earth Data

Database preparation

The following terminal commands will create a database named naturalearth, assuming that your user account has create database privilege:

createdb naturalearth

Load the PostGIS extension as superuser (postgres):

psql -U postgres -d naturalearth -c 'CREATE EXTENSION postgis'

Import shapefile

The data used in the examples are loaded from Natural Earth. Download the Admin 0 - Countries ZIP and extract to a location on your machine.

In that directory, run the following command in the terminal to load the shapefile data into the naturalearth database. This creates a new table ne_50m_admin_0_countries, with the application user as the owner – refer to Table Layers and Security for more information on access to spatial tables on pg_tileserv.

shp2pgsql -D -s 4326 ne_50m_admin_0_countries.shp | psql -U username -d naturalearth

You should see the ne_50m_admin_0_countries table with the \dt SQL shell command.

Make sure that pg_tileserv connection specifies naturalearth, i.e.: DATABASE_URL=postgres://username:password@host/naturalearth. With the service running, you should also see the layer on the web preview, i.e.: http://localhost:7800/public.ne_50m_admin_0_countries.html
