Assessment of approaches and costs associated with the correction of the HRDEM product data in the Canadian Arctic / C. Papasodoro, D. Bélanger, G. Légaré-Couture, H.A.J. Russell, and 4DM Inc. : M103-3/74-2023E-PDF
"The High-Resolution Digital Elevation Model (HRDEM) was created as part of the National Elevation Data Strategy to provide detailed elevation data across the country. For the Canadian Arctic, the HRDEM was based on the Arctic DEM initiative with additional post-processing by the Canada Centre for Mapping and Earth Observation (CCMEO) to create a 2-meter Digital Surface Model (DSM) covering a geographic region of approximately 4.6 million km². This report provides details on the investigation of the data issues within HRDEM, available open and commercial sources of elevation data that could be used to improve the DSM, and technologies available to generate high resolution DSM at similar levels of accuracy and resolution than the current HRDEM. In addition, the report summarizes the results of a research into the common, as well as more advanced (e.g., machine learning), methods for improving DSM"--Introduction, page 1.
