Buffer a KML Layer and the Send Result To a Geoprocessing Service
KML layers in the ArcGIS API for JavaScript give you full access to the features
in a KML file. For this app, a KML file representing most of the Chesapeake and Ohio Canal
near Washington, DC is added to the map. The features from the KML layer
are first buffered using a geometry service and then population within the buffer
is calculated via a geoprocessing service.
