-## Importing multiple regions
+## Importing multiple regions (without updates)
-To import multiple regions in your database, you need to configure and run `utils/import_multiple_regions.sh` file. This script will set up the update directory which has the following structure:
+To import multiple regions in your database you can simply give multiple
+OSM files to the import command:
+
+```
+nominatim import --osm-file file1.pbf --osm-file file2.pbf
+```
+
+If you already have imported a file and want to add another one, you can
+use the add-data function to import the additional data as follows:
+
+```
+nominatim add-data --file <FILE>
+nominatim refresh --postcodes
+nominatim index -j <NUMBER OF THREADS>
+```
+
+Please note that adding additional data is always significantly slower than
+the original import.
+
+## Importing multiple regions (with updates)
+
+If you want to import multiple regions _and_ be able to keep them up-to-date
+with updates, then you can use the scripts provided in the `utils` directory.
+
+These scripts will set up an `update` directory in your project directory,
+which has the following structure:
```bash
update
│ └── monaco
│ └── sequence.state
└── tmp
- ├── combined.osm.pbf
└── europe
├── andorra-latest.osm.pbf
└── monaco-latest.osm.pbf
```
-The `sequence.state` files will contain the sequence ID, which will be used by pyosmium to get updates. The tmp folder is used for import dump.
-
-### Configuring multiple regions
-
-The file `import_multiple_regions.sh` needs to be edited as per your requirement:
-
-1. List of countries. eg:
-
- COUNTRIES="europe/monaco europe/andorra"
-
-2. Path to Build directory. eg:
+The `sequence.state` files contain the sequence ID for each region. They will
+be used by pyosmium to get updates. The `tmp` folder is used for import dump and
+can be deleted once the import is complete.
- NOMINATIMBUILD="/srv/nominatim/build"
-
-3. Path to Update directory. eg:
-
- UPDATEDIR="/srv/nominatim/update"
-
-4. Replication URL. eg:
-
- BASEURL="https://download.geofabrik.de"
- DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
### Setting up multiple regions
-!!! tip
- If your database already exists and you want to add more countries,
- replace the setting up part
- `${SETUPFILE} --osm-file ${UPDATEDIR}/tmp/combined.osm.pbf --all 2>&1`
- with `${UPDATEFILE} --import-file ${UPDATEDIR}/tmp/combined.osm.pbf --index --index-instances N 2>&1`
- where N is the numbers of CPUs in your system.
-
-Run the following command from your Nominatim directory after configuring the file.
-
- bash ./utils/import_multiple_regions.sh
-
-!!! danger "Important"
- This file uses osmium-tool. It must be installed before executing the import script.
- Installation instructions can be found [here](https://osmcode.org/osmium-tool/manual.html#installation).
-
-### Updating multiple regions
-
-To import multiple regions in your database, you need to configure and run ```utils/update_database.sh```.
-This uses the update directory set up while setting up the DB.
+Create a project directory as described for the
+[simple import](Import.md#creating-the-project-directory). If necessary,
+you can also add an `.env` configuration with customized options. In particular,
+you need to make sure that `NOMINATIM_REPLICATION_UPDATE_INTERVAL` and
+`NOMINATIM_REPLICATION_RECHECK_INTERVAL` are set according to the update
+interval of the extract server you use.
-### Configuring multiple regions
+Copy the scripts `utils/import_multiple_regions.sh` and `utils/update_database.sh`
+into the project directory.
-The file `update_database.sh` needs to be edited as per your requirement:
+Now customize both files as per your requirements
-1. List of countries. eg:
+1. List of countries. e.g.
COUNTRIES="europe/monaco europe/andorra"
-2. Path to Build directory. eg:
+2. URL to the service providing the extracts and updates. eg:
- NOMINATIMBUILD="/srv/nominatim/build"
-
-3. Path to Update directory. eg:
-
- UPDATEDIR="/srv/nominatim/update"
-
-4. Replication URL. eg:
-
BASEURL="https://download.geofabrik.de"
- DOWNCOUNTRYPOSTFIX="-updates"
+ DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
-5. Followup can be set according to your installation. eg: For Photon,
+5. Followup in the update script can be set according to your installation.
+ E.g. for Photon,
FOLLOWUP="curl http://localhost:2322/nominatim-update"
will handle the indexing.
+
+To start the initial import, change into the project directory and run
+
+```
+ bash import_multiple_regions.sh
+```
+
### Updating the database
-Run the following command from your Nominatim directory after configuring the file.
+Change into the project directory and run the following command:
- bash ./utils/update_database.sh
+ bash update_database.sh
-This will get diffs from the replication server, import diffs and index the database. The default replication server in the script([Geofabrik](https://download.geofabrik.de)) provides daily updates.

## Importing Nominatim to an external PostgreSQL database
the PostgreSQL server itself.
Download and compile Nominatim as per standard instructions. Once done, you find
-the nomrmalization library in `build/module/nominatim.so`. Copy the file to
+the normalization library in `build/module/nominatim.so`. Copy the file to
the database server at a location where it is readable and executable by the
PostgreSQL server process.
