The goal of this project is to provide a web service providing inland waterbodies initially available on GeoBase and updated using the most recent Landsat-8 imagery. The system ingests multispectral imagery (30 meters resolution) over Canada on a monthly basis (from May to September) and updates the waterbody outlines using an image processing software developed at CRIM. Updated waterbodies are available through a GeoRSS service or through a RESTful service in XML, KML, SHP or GeoJSON formats.

For a quick access to the service see here.
This project was realized by the Vision and Imaging Team between November 2013 and May 2014 and has been financed in part by CANARIE (IRP program). Note that the system is still under construction and will be maintained until at least 2016.
