Getting started
Consult our guide to mapping in California, which complements the global tagging reference. If you are mapping based on street-level imagery, the California MUTCD reference pages make it easy to translate what you see into detailed tags.

Worklists
The following pages keep track of our progress in mapping certain kinds of features that are mapped as relations:
- State and county highways
- Railroads, rail infrastructure routes, and passenger rail routes
- Designated bicycle routes
- Designated hiking routes
- Freeway endpoints for highway classification
We are also tracking a number of imports of open data. As of January 2022, there is an ongoing discussion of moving the state to an importance-based trunk highway classification scheme.
Without an "import everything" attitude, since 2019 the California Protected Areas Database has had select polygons from it curated into OSM, frequently to clarify "park boundaries" or other boundary=protected_areas. See California/Using_CPAD_data for suggestions on how OSM might best use these data. The data's publisher, GreenInfo, asks (but does not require) that OSM gives source attribution as these ODbL-compliant data enter OSM.
