Koop is an Open Geospatial ETL Engine that allow anyone to transform, query, and download geospatial data on the web.

Table of contents


Koop is a highly-extensible Javascript toolkit for connecting incompatible spatial APIs. Out of the box it exposes a Node.js server that can translate GeoJSON into the Geoservices specification supported by the ArcGIS family of products (GeoJSON, CSV, KML, Shapefile and Feature Service). 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.
