Where does the open charge map data come from? Are they constantly updated? Is a check done before they are uploaded?
Approximately half of OCM data is manually entered by users in the community. Imported data may come from networks and government open data registrars but currently not that many: https://openchargemap.org/site/about
Imports are periodically updated but not automatically (currently) and the import process does some basic deduplication checks.
Manually entered data is submitted for review by country editors and is automatically published if nobody reviews it within a few days, or if the user submitting is already a country editor.
