Koop - an open source GeoSpatial ETL engine

Transform geospatial data on the fly and serve as GeoJSON, Vector Tiles, Feature Services and more

What is Koop?


Koop is a JavaScript toolkit for connecting spatial APIs. Out of the box, it exposes a Node.js server that translates GeoJSON into the GeoServices specification supported by ArcGIS products. It's plugin architecture supports output in other formats including vector-tile, WMS, and plain old GeoJSON.


Koop can be extended to translate data from any source to any API specification. Don’t let API incompatiblity get in your way, start using one of Koop’s data providers or write your own.
