from an OSM planet file and how to keep the database up to date. It

you should also enable flatnode storage of node locations. With this
setting enabled, node coordinates are stored in a simple file instead
of the database. This will save you import time and disk storage.

Installing Tiger housenumber data for the US

instance by following these steps:
- 1. Install the GDAL library and python bindings

- Ubuntu: apt-get install python-gdal
- CentOS: yum install gdal-python
+ * Ubuntu: `sudo apt-get install python-gdal unzip`

2. Get the TIGER 2015 data. You will need the EDGES files

3. Convert the data into SQL statements (stored in data/tiger):
- ./utils/imports.php --parse-tiger <tiger edge data directory>
+ ./utils/imports.php --parse-tiger <tiger edge data directory>
4. Import the data into your Nominatim database:
- ./utils/setup.php --import-tiger-data

+ 5. Enable use of the Tiger data in your `settings/local.php` by adding:
+
+ @define('CONST_Use_US_Tiger_Data', true);
+
+ 6. Apply the new settings:
+
+ ./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
Be warned that the import can take a very long time, especially if you
