# OpenHistoricalMap - **Website:** - **Primary alias:** `openhistoricalmap.org` ## Description OpenHistoricalMap is a collaborative, interactive map that shows places and geographic features across different periods of history. Created by contributors, it is dedicated to the public domain, making its historical map data available for public use, except where otherwise noted. The project is a charter initiative of OpenStreetMap U.S., a 501(c)(3) nonprofit affiliated with the OpenStreetMap Foundation. Visitors can explore the map, choose from available map layers, view map keys, and share locations. The site also provides tools for contributing and maintaining map data, including an in-browser editor and links to external editing software. Users can review map history, export data, and access features such as GPS traces and user diaries. Routing options include GraphHopper, OSRM, and Valhalla. OpenHistoricalMap supports community participation through mapping resources, information about the project, and donation opportunities. Its public-domain focus and open contribution model make it a shared resource for exploring and documenting how the world has changed over time. ## Industries - 🗺 Reference Materials - 🗺 Maps _(under Reference Materials)_ ## Links - [facebook](https://facebook.com/Open-Historical-Map-515547755294262) - [twitter](https://twitter.com/openhistmap) ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idCcBxist5/w/500/h/500/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1792996195811) - icon _(primary)_ — JPEG — [download](https://cdn.brandfetch.io/idCcBxist5/w/300/h/300/theme/dark/icon.jpeg?c=1bxid64Mup7aczewSAYMX&t=1792996195916) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Moss Green | #c4e3b9 | accent | | Sepia Skin | #96543d | dark | | Ziggurat | #badce3 | light | ## Fonts - var(--bs-body-font-family) — asset _(custom)_ - var(--bs-font-sans-serif) — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
