This prototype uses a Web Processing Service (WPS) in accordance with the Open Geosopatial Consortium (OGC) specifications which allows network analysis on GeoBase's National Hydro Network. We would appreciate receiving your comments in order to guide the future development of this new service. Two types of analysis are available :

Upstream

This function finds network flow lines located upstream of a point. Select this option and click on the map close to a flow line in order to retrieve the upstream network geometry.

Downstream

This function finds network flow lines located downstream of a point. Select this option and click on the map close to a flow line in order to retrieve the downstream network geometry.

Note: This service allows only three simultaneous requests. Please use the following link for direct access to the GeoBase WPS service: http://ows.geobase.ca/wps/geobase?request=GetCapabilities&version=1.0.0&service=wps
