We need to setup our own OSM server ([login to view URL]) to facilitate the resolution of GPS coordinates to addresses (reverse geocoding). OSM has a system called Nominatim which can be setup as a standalone server: [login to view URL]
The job comprises of 2 parts:
1) Setup the initial Nominatim server and upload the initial DB
2) Make sure the Nominatim server stays up-to-date automatically with cron-based update scripts
Please ONLY apply for this job if you have extensive knowledge about PostgreSQL setup, tuning and maintenance.
