Import Natural Earth data into PostGIS
In this tutorial, we'll learn how to use Baremaps to import Natural Earth data in a PostGIS database.
Notice that the following steps assume that the Apache Baremaps CLI and PostGIS are installed (opens in a new tab).
Natural Earth (opens in a new tab) is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales.
The following workflow will download the Natural Earth data, decompress it, and finally import it in the database.
baremaps workflow execute --file examples/naturalearth/workflow.json
Working with shapefiles (Optional)
The NaturalEarth dataset is also distributed in the shapefile format (opens in a new tab).
As demonstrated in the following command, shapefiles can easily be imported in postgis with
Here, notice that the data is reprojected in WebMercator (EPSG:3857) to improve performance at query time.
ogr2ogr \ -f "PostgreSQL" "PG:host=localhost user=baremaps dbname=baremaps password=baremaps" \ "ne_10m_admin_0_countries.shp" \ -lco GEOMETRY_NAME=geom \ -lco FID=gid \ -lco PRECISION=no \ -nlt PROMOTE_TO_MULTI \ -nln ne_10m_admin_0_countries \ -s_srs EPSG:4326 \ -t_srs EPSG:3857 \ --config OGR_ENABLE_PARTIAL_REPROJECTION TRUE \ -overwrite
In this tutorial, we learnt how to import Natural Earth data in PostGIS.
Now that you have inserted the data into the PostGIS database, you can use follow the Serve Vector Tiles from PostGIS example to serve your PostGIS data directly as Vector Tiles in a web application with live reload capabilities.
