an Esri Leaflet plugin for interacting with geoprocessing services published with ArcGIS Server and the analysis services hosted in ArcGIS Online.
Esri Leaflet GP relies on the minimal Esri Leaflet Core which handles abstraction for requests and authentication when necessary.
Note that the latest version of this plugin requires a minimum of esri-leaflet 2.0.0.
The demos below show the plugin in action
- calculate a drivetime polygon
- generate an elevation profile
- route to the closest facility
- solve a vehicle routing problem
