kandi X-RAY | nominatim-ac Summary

nominatim-ac is a Kotlin library. nominatim-ac has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This code dumps out the contents of a populated Nominatim postgres instance into Elasticsearch and exposes it as a JSON web service. Ther is some useful intuition here around reliably paging through the entire places table. The service is able to quickly respond to key stokes as the Nominatim output has been pre-rendered and indexed and does not need to be calculated in real time. The Elasticsearch index can be distributed to smaller machines than those needed to run a whole planet Nominatim instance. The Nominatim place name and OSM id is made available in the JSON returned to clients. The calling application can now persist the OSM id of the selected result for future reference.

Install nominatim-ac

The Elasticsearch index is populated by reading from the Postgres database of a locally running Nominatim instance. Installing a whole world Nominatim instances is a fairly large undertaking. From experience a full world Nominatim instance requires a machine with at least 32GB of RAM available. I struggled to build a consumer machine which could complete ea full install. A full install was. Back in 2013 the Nominatim import of planet.osm took approximately 6 weeks to complete and consumed around 1TB of disk (single CPU HP DL360 server with 48Gb of RAM; single SATA SSD drive). In 2021 this import takes around 3 days (HP z620; dual CPU; 96Gb RAM; 1.5TB of NVME SSD). Mediagis have published a Nominatim Docker build which can be used for local development (https://github.com/mediagis/nominatim-docker).
