Created and maintained by the [MapTiler team](https://www.maptiler.com/), it serves as a _custom_ interface to the [EPSG database](https://en.wikipedia.org/wiki/EPSG_Geodetic_Parameter_Dataset).\n\nThe service offers a list of projections, coordinate systems, bounding boxes, and transformation options for improved precision in coordinate transformations.\n\nFor detailed documentation, visit [epsg.io/docs](https://epsg.io/docs).\n\n## Discovering coordinate systems, ellipsoids, transformations, units\nCoordinate systems, ellipsoids, transformations, and units can be discovered directly via the search field at [EPSG.io](https://epsg.io/). The interface supports searching by EPSG codes (e.g., `3857`) or by part of the system's name (e.g., `pseudo-mercator`). Try [epsg.io/2056](https://epsg.io/2056) as an example.\n\n## Export formats for all software\n[EPSG.io](https://epsg.io/) offers coordinate reference system definitions in formats compatible with a wide range of geospatial software, including PROJ, GeoServer, Proj4.js, PostGIS, ESRI ArcGIS, and OGC WKT. For example, see [epsg.io/2056-1676.wkt2](https://epsg.io/2056-1676.wkt2).\n\n## EPSG.io endpoints\nUsing [EPSG.io](https://epsg.io/) endpoints allows users to discover coordinate systems, ellipsoids, units, and other objects, and retrieve specific coordinate definitions in various formats. For more details, visit [epsg.io/docs](https://epsg.io/docs).\n\n## Coordinates API \n\n![MapTiler logo](./static/img/maptiler-logo-small.png) \n\n**EPSG.io** is a custom, open service provided by [MapTiler](https://www.maptiler.com/), free of charge. The **Coordinate transformation and search service** is powered by the [MapTiler Coordinates API](https://documentation.maptiler.com/hc/en-us/articles/16551987730193-Coordinates-API). In addition to being compatible with EPSG.io, it introduces the [/transform](https://docs.maptiler.com/cloud/api/coordinates/#transform-coordinates) endpoint for coordinate transformations and [/search](https://docs.maptiler.com/cloud/api/coordinates/#search-coordinate-systems) endpoint for searching through coordinate systems and its components.\n\nThe **Coordinates API** from MapTiler offers:\n* API for **coordinate transformations**\n* API for **searching** and **discovering** coordinate reference systems\n* **Stable, reliable service** for integration into applications\n* Option to use a dedicated MapTiler API key, enabling cost management across **multiple apps**\n* **Batch transformations** for up to 50 points\n\nFor detailed API documentation, visit [docs.maptiler.com/cloud/api/coordinates/](https://docs.maptiler.com/cloud/api/coordinates/).\n\n## Migration endpoints from EPSG.io to MapTiler Coordinates API\nEPSG.io  is transitioning to the [MapTiler Coordinates API](https://documentation.maptiler.com/hc/en-us/articles/16551987730193-Coordinates-API) for `search` and `transform` services, providing a more secure, robust, and scalable solution.\n\n### Old endpoints:\n\nSearch: `https://epsg.io/?q=swiss\u0026format=json`\n\nTransform: `https://epsg.io/trans?data=7.457914,46.948563\u0026s_srs=4326\u0026t_srs=2056`\n\n### New endpoints:\n\nSearch: `https://api.maptiler.com/coordinates/search/swiss.json?key=MapTiler-key`\n\nTransform: `https://api.maptiler.com/coordinates/transform/7.457914,46.948563.json?s_srs=4326\u0026t_srs=2056\u0026key=MapTiler-key`\n\nFor more details on migration, including JSON response changes and how to get your MapTiler key, read the [migration guide](https://documentation.maptiler.com/hc/en-us/articles/360020950098-How-to-migrate-from-EPSG-io-to-MapTiler-Coordinates-API).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmaptiler%2Fepsg.io","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmaptiler%2Fepsg.io","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmaptiler%2Fepsg.io/lists"}
