27 Add additional data from a file or an online source.
29 This command allows to add or update the search data in the database.
30 The data can come either from an OSM file or single OSM objects can
31 directly be downloaded from the OSM API. This function only loads the
32 data into the database. Afterwards it still needs to be integrated
33 in the search index. Use the `nominatim index` command for that.
35 The command can also be used to add external non-OSM data to the
36 database. At the moment the only supported format is TIGER housenumber
37 data. See the online documentation at
38 https://nominatim.org/release-docs/latest/admin/Import/#installing-tiger-housenumber-data-for-the-us
