Import all data necessary to compute addresses down to house number level.
* **settings/import-full.style**
Default style that also includes points of interest.
+* **settings/import-extratags.style**
+ Like the full style but also adds most of the OSM tags into the extratags
+ column.
The style can be changed with the configuration `CONST_Import_Style`.
street | 42h | 400 GB | 180 GB
address | 59h | 500 GB | 260 GB
full | 80h | 575 GB | 300 GB
+extratags | 80h | 585 GB | 310 GB
You can also customize the styles further. For a description of the
style format see [the development section](../develop/Import.md).
In the first step of the import Nominatim uses osm2pgsql to load the OSM data
into the PostgreSQL database. This step is very demanding in terms of RAM usage.
osm2pgsql and PostgreSQL are running in parallel at this point. PostgreSQL
-blockes at least the part of RAM that has been configured with the
+blocks at least the part of RAM that has been configured with the
`shared_buffers` parameter during [PostgreSQL tuning](Installation#PostgreSQL_tuning)
and needs some memory on top of that. osm2pgsql needs at least 2GB of RAM for
its internal data structures, potentially more when it has to process very large
swapping or you are getting out-of-memory errors, reduce the cache size or
even consider using a flatnode file.
