## Description

EPSG.io is an online resource for exploring coordinate reference systems and working with geographic coordinates. Made by the MapTiler Team, the service helps users search the EPSG database, find coordinate system codes, and view locations on a map. Its tools support coordinate transformation, allowing users to convert positions between coordinate systems, while system pages provide details and formats including WKT, OGC GML, and Proj.4.

The site covers worldwide systems, with examples such as WGS84, commonly used with GPS; Spherical Mercator, associated with web mapping services including Google Maps, OpenStreetMap, and Bing; and UTM and ETRS systems. Users can browse systems by region or country, including the United Kingdom, France, Czech Republic, Germany, the Netherlands, and Switzerland.

For development and larger-scale workflows, EPSG.io also points to the MapTiler Coordinates API, which supports automated coordinate conversion and EPSG code searches, including batch transformation. The service is presented as running on high-availability infrastructure with fast, reliable servers. Overall, EPSG.io combines coordinate-system reference information, map-based exploration, and practical conversion tools.
