# Migrate from GeoJSON

export const InternalLink = ({version, path = "", children, ...props}) => {
  let detectedVersion = version || "stable";
  if (typeof window !== 'undefined' && !version) {
    const match = window.location.pathname.match(/\/docs\/([^/]+)/);
    if (match) {
      detectedVersion = match[1];
    }
  }
  const normalizedPath = path.startsWith("/") ? path.slice(1) : path;
  return <a href={`/docs/${detectedVersion}/${normalizedPath}`} {...props}>
      {children}
    </a>;
};

CockroachDB supports efficiently storing and querying <InternalLink path="export-spatial-data">spatial data</InternalLink>.

This page has instructions for migrating data from the [GeoJSON](https://wikipedia.org/wiki/GeoJSON) format into CockroachDB using [`ogr2ogr`](https://gdal.org/programs/ogr2ogr) and <InternalLink path="import">`IMPORT`</InternalLink>.

In the example below we will import a data set with [the locations of underground storage tanks in the state of Vermont (USA)](https://anrweb.vt.gov/DEC/ERT/UST.aspx?ustfacilityid=96).

## Before You Begin

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

* CockroachDB <InternalLink path="install-cockroachdb">installed</InternalLink> and <InternalLink path="start-a-local-cluster">running</InternalLink>
* [`ogr2ogr`](https://gdal.org/programs/ogr2ogr)
* [Python 3](https://www.python.org/)

<Note>
  An `ogr2ogr` version of 3.1.0 or higher is required to generate data that can be imported into CockroachDB.
</Note>

## Step 1. Download the GeoJSON data

First, download the storage tank GeoJSON data:

```shell theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
curl -o tanks.geojson https://geodata.vermont.gov/datasets/986155613c5743239e7b1980b45bbf36_162.geojson
```

## Step 2. Convert the GeoJSON data to SQL

Next, convert the GeoJSON data to SQL using the following `ogr2ogr` command:

```shell theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
ogr2ogr -f PGDUMP tanks.sql -lco LAUNDER=NO -lco DROP_TABLE=OFF tanks.geojson
```

An `ogr2ogr` version of 3.1.0 or higher is required to generate data that can be imported into CockroachDB.

## Step 3. Host the files where the cluster can access them

Each node in the CockroachDB cluster needs to have access to the files being imported. There are several ways for the cluster to access the data; for a complete list of the types of storage <InternalLink path="import">`IMPORT`</InternalLink> can pull from, see <InternalLink path="import#import-file-location">import file locations</InternalLink>.

For local testing, you can <InternalLink path="use-a-local-file-server">start a local file server</InternalLink>. The following command will start a local file server listening on port 3000:

```shell theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
python3 -m http.server 3000
```

## Step 4. Prepare the database

Next, create a database to hold the storage tank data:

```shell theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
cockroach sql --insecure
```

```sql theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
CREATE DATABASE IF NOT EXISTS tanks;
USE tanks;
```

## Step 5. Import the SQL

Since the file is being served from a local server and is formatted as PostgreSQL-compatible SQL, we can import the data using the following <InternalLink path="import#import-a-postgresql-database-dump">`IMPORT PGDUMP`</InternalLink> statement:

```sql theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
IMPORT PGDUMP ('http://localhost:3000/tanks.sql');
```

```text theme={"theme":{"light":"catppuccin-mocha","dark":"catppuccin-mocha"}}
        job_id       |  status   | fraction_completed | rows | index_entries | bytes
---------------------+-----------+--------------------+------+---------------+---------
  588555793549328385 | succeeded |                  1 | 2709 |          2709 | 822504
(1 row)
```
