Migrate from OpenStreetMap

On this page

CockroachDB supports efficiently storing and querying spatial data.

This page has instructions for migrating data from OpenStreetMap .pbf data files into CockroachDB using osm2pgsql and IMPORT.

In the example below we will import the OSM data for Australia that is available from GeoFabrik GmbH.

Before You Begin

To follow along with the example below, you will need the following prerequisites:

CockroachDB installed and running
osm2pgsql

Step 1. Download the OpenStreetMap data

First, download the OSM data:

wget https://download.geofabrik.de/australia-oceania/australia-latest.osm.pbf

Step 2. Prepare the database

cockroach sql --insecure

Next, create a database to hold the Australia map data:

CREATE DATABASE IF NOT EXISTS australia;
USE australia;

Step 3. Import the OpenStreetMap data

Run the osm2pgsql command shown below to convert the OSM data and import it into the australia database. The arguments to osm2pgsql shown below assume a locally running insecure cluster and may need to be changed depending on your system. You may also need to tweak the cache setting (-C) depending on your system's hardware.

osm2pgsql -C 2048 -d australia -U root -H localhost -P 26257 australia-latest.osm.pbf

This will take a few (30+) minutes to run on a laptop, and there will be a lot of output. A successful run will look something like the following:
