This library simplifies the process of using compressed geometry with maplibre-gl-js in JavaScript applications and with maplibre-native in Kotlin and Swift applications.

Location-based service providers sometimes use variations of the Encoded Polyline Algorithm Format to reduce the response size for APIs that can return large arrays of coordinates, such as routing and isoline APIs. The utility methods in this library compresses the data and decompresses into GeoJSON that can be directly rendered in MapLibre.

Documentation for each supported language can be found here:

• JavaScript
• Kotlin
• Swift
