The cut and fill is calculated either by comparing two DTMs, or by comparing a DTM with the height of a horizon plane. You can use this tool to calculate the cut and fill according to REB. You can use this tool to create a profile section based on existing profiles. You can use this tool to apply different shades of color to the various height levels in a DTM. You can use this function to label the triangles, contours and points in a DTM. You can use this tool to convert DTM elements to 2D. You can use this tool to convert 3D entities to a DTM element. You can use this tool to convert DTM elements to a surface model or solid. The files are exported to and imported from the user's data exchange folder. You can use this tool to import point files and location line files in a variety of formats or export points and coordinates to a file. You can use this tool to place a profile through a terrain using orthogonal, inclined and freeform section lines, and to modify an existing profile section. You can use this tool to place elevation points in a DTM. You can use this tool to draw contour lines in a DTM. You can use this tool to create a new digital terrain model or optimize an existing one.

The HRDEM and HRDEM Mosaic products are part of the CanElevation Series created in support of the National Elevation Data Strategy.You can use this tool to create points with point symbols (2D oder 3D), primary and secondary point numbers as well as stations and point coding. Collaboration with various partners is a key factor in the success of the Strategy, both to release existing data and to acquire new LiDAR data across the country. The National Elevation Data Strategy aims to increase high-resolution elevation data coverage for Canada and improve accessibility to the products. About the National Elevation Data Strategy The WMS service facilitates the visualization of the mosaic and its derived products, while the WCS provides access to the source data. The HRDEM Mosaic is also available from WMS and WCS web mapping services – see the product specifications for more details.

A download procedure for the HRDEM product is also now available. For more information on the HRDEM product, consult the product specifications. Use one of the following options to view the current inventory: "View on Map", "Project Footprints" or "Dataset Footprints". The HRDEM data can be downloaded from the Open Government Portal in KML, Shapefile or ESRI REST formats. This highly detailed 3D information provides essential foundational geospatial data for many government projects and priorities, such as flood mapping, forest inventories, climate change monitoring and urban management. The 10,000 km2 project was carried out in collaboration with the City of Ottawa, the City of Gatineau, NRCan, the National Capital Commission (NCC) and the Province of Ontario and supported by the Emergency Management Strategy for Canada. This includes the entire area of both the National Capital Region and the Ottawa River, areas that are highly vulnerable to flooding. With the addition of this data, 61 of Canada's 100 largest cities are covered by the HRDEM product and the HRDEM Mosaic. The data is distributed across eight provinces: British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland and Labrador (see map below). The total area of high-resolution elevation data derived from LiDAR is now nearly 500,000 km². Natural Resources Canada (NRCan) is pleased to announce the release of over 100,000 km2 of new data in the High-Resolution Digital Elevation Model (HRDEM) and HRDEM Mosaic.
