| Summary | (Plain Language Summary, not published)
Development of a process to integrate different Canadian terrain datasets, the (i) older Canadian Digital Elevation Model ( CDEM) which covers the whole
of Canada and the (ii) new, high-resolution terrain model (HRDEM) which is created from LiDAR and has partial coverage. This process tested the integration and modelling on DGGS at the native resolution and compared the elevation values at different
resolutions to survey ground control points. |
