<p>The City of Prince George Hydropoly and hydroline datasets are used to portray surface water. The hydopoly and hydroline datasets represent the drainage network with features such as rivers, streams, canals, lakes, ponds and dams. These datasets were derived from the DEm produced from the 2014 LiDAR data capture point cloud.</p><p>These polygon areas are defined by their subtypes using the CCSM codes;</p><p style='MARGIN: 1px 1px 1px 20px'>Canada Council on Surveying and Mapping, the custodian of national feature codes.
