The purpose of this dataset is to show end users where LiDAR data has been acquired by the Government of Manitoba. LiDAR (Light Detection and Ranging) is a remote sensing technology that uses lasers to collect accurate, continuous elevation data over relatively large areas. These data are essential for activities such as forestry, flood risk management, land use planning, and natural resources management. The Manitoba Government is increasingly acquiring LiDAR data across the province.This layer was created on August 5, 2009 by Manitoba Sustainable Development and was updated on August 9, 2021.To download LiDAR data from the Manitoba Land Initiative (MLI) site, follow this link: https://mli2.gov.mb.ca/dems/index_external_lidar.html Fields included ( Alias (Field Name): Field description.)

The High Resolution Digital Elevation Model (HRDEM) product is derived from airborne LiDAR data (mainly in the south) and satellite images in the north. The complete coverage of the Canadian territory is gradually being established. It includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived data. For DTM datasets, derived data available are slope, aspect, shaded relief, color relief and color shaded relief maps and for DSM datasets, derived data available are shaded relief, color relief and color shaded relief maps. The productive forest line is used to separate the northern and the southern parts of the country. This line is approximate and may change based on requirements. In the southern part of the country (south of the productive forest line), DTM and DSM datasets are generated from airborne LiDAR data. They are offered at a 1 m or 2 m resolution and projected to the UTM NAD83 (CSRS) coordinate system and the corresponding zones. The datasets at a 1 m resolution cover an area of 10 km x 10 km while datasets at a 2 m resolution cover an area of 20 km by 20 km. In the northern part of the country (north of the productive forest line), due to the low density of vegetation and infrastructure, only DSM datasets are generally generated. Most of these datasets have optical digital images as their source data. They are generated at a 2 m resolution using the Polar Stereographic North coordinate system referenced to WGS84 horizontal datum or UTM NAD83 (CSRS) coordinate system. Each dataset covers an area of 50 km by 50 km. For some locations in the north, DSM and DTM datasets can also be generated from airborne LiDAR data. In this case, these products will be generated with the same specifications as those generated from airborne LiDAR in the southern part of the country. The HRDEM product is referenced to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the reference standard for heights across Canada. Source data for HRDEM datasets is acquired through multiple projects with different partners. Since data is being acquired by project, there is no integration or edgematching done between projects. The tiles are aligned within each project. The product High Resolution Digital Elevation Model (HRDEM) is part of the CanElevation Series created in support to the National Elevation Data Strategy implemented by NRCan. Collaboration is a key factor to the success of the National Elevation Data Strategy. Refer to the “Supporting Document” section to access the list of the different partners including links to their respective data.

Digital Elevation Model (DEM) of a subwatershed in the La Salle watershed, north of Elie, MB. Data was derived from LiDAR and is produced at a 1 metre resolution. LiDAR data was collected using Fugro Horizons proprietary FLI-MAP Fx LiDAR system.For more information, visit: http://open.canada.ca/data/en/dataset/aba9fd46-2921-43f6-9bdb-c9f021aee4ee / Modèle altimétrique numérique (MAN) d'un sous-bassin hydrographique dans le bassin hydrographique La Salle au nord d'Elie au Manitoba. Les données proviennent des levés LiDAR avec une résolution de 1 mètre.

The NCC Tall Grass Prairie Preserve resource collection contains a LiDAR-based digital elevation model and derivative grids in the vicinity of Nature Conservancy Canada's Weston Family Tall Grass Prairie Interpretive Centre, located in Stuartburn Rural Municipality, southeast Manitoba, Canada. This ESRI grid file, vc_dem, contains a 1 m square raster of processed LiDAR ground return data, and is hydrologically corrected to include culverts. The area of the grid is give in the associated polygon shape file that delineates the area of interest (AOI).

This LiDAR DEM, originated from the Government of Manitoba (2019-05), was hydro-conditioned with a recent culvert inventory including GIS data from the Province of Manitoba for provincial highways as well as hard copy maps from the Rural Municipality of Lorne. It also included GPS and desktop surveys as part of a collaborative effort between Agriculture and Agri-Food Canada, Swan Lake First Nation, and Pembina Valley Watershed District. The hydro-conditioned DEM was used by the International Institute for Sustainable Development (IISD) as input for hydrological modelling of catchments near Swan Lake flowing into the Pembina River (Pembina River Watershed, MB) to spatially target water-related agricultural beneficial management practices (e.g, flood management infrastructure, water retention structures, nutrient and sediment load reduction practices). The DEM spatial extent represents the area of interest referred to as the “Swan Lake Study Area”, as part of the Eastern Prairies Living Lab, AAFC (2019-2023).

This data set contains surface elevation data over Greenland, Alaska, and Antarctica, measured by the NASA Land, Vegetation, and Ice Sensor (LVIS), an airborne lidar scanning laser altimeter. The data were collected as part of NASA Operation IceBridge funded campaigns.
