For example, those working in the California CommunityĬollege system could probably get away with the California Planet’s data is not necessary in nearly all institutional researchĪpplications.

In subsequent sections, we illustrate how to implement this using Docker on a local computer running Leaves the local network during the geocoding process, or even the localĬomputer if the service is set up as outlined in this vignette. With the local server (essentially a lookup in the database). That is, we can set up a web server with OSMĭata loaded into a PostgreSQL database, where the user could geocode One privacy-respecting approach to geocoding is to install Nominatim on a local server, and use Safeguard private information, and to be mindful about the services that Services to remind institutional researchers about their duty to We point out the privacy policies of two commonly used and free This information is only used to monitor and track the performance ofīased on this response, one could infer that the submitted addressesĪre retained, but the retention period is not known.
