# Open Map and Geo Data for Developers

Open map data, live geo feeds and historical maps you can put on a map in your app, with the attribution each one needs.

## Open sources

- OpenStreetMap: A free, editable map of the world built by volunteers, whose full map database can be downloaded as open data. [API, no key; commercial use with conditions] https://agentgid.com/resources/openstreetmap/agent.md
- USGS Latest Earthquakes: The US government's live map and catalog of earthquakes worldwide, with minute-by-minute GeoJSON feeds and a searchable query API. [API, no key; commercial use ok] https://agentgid.com/resources/usgs-earthquakes/agent.md
- Global Forest Watch: WRI's map and data platform for tracking forest loss, deforestation alerts and land use worldwide from satellite data, with a public Data API; globalforestwatch.org now redirects to Global Nature Watch. [API with key; commercial use with conditions] https://agentgid.com/resources/global-forest-watch/agent.md
- The True Size Of: A free browser map where you drag country, state and region outlines across a Mercator map to see their real size at any latitude, with area and population shown. [no API; commercial use unclear] https://agentgid.com/resources/the-true-size/agent.md
- David Rumsey Map Collection: An online archive of over 151,000 scanned historical maps and images, many free to download, plus a Georeferencer for placing old maps on modern ones. [no API; commercial use with conditions] https://agentgid.com/resources/david-rumsey-map-collection/agent.md
