Dempster Highway Orthomosaic (2019)

Dempster Highway Orthomosaic (2019) In July and August of 2019, a remotely piloted aircraft system (RPAS) project was undertaken in Canada’s western Arctic along the Inuvik to Tuktoyaktuk (ITH) and Dempster highways. The objective of this project was to test long-range RPAS missions for photogrammetric data acquisition and processing of these two Arctic highway corridors with embankments, bridges and culverts at risk of changing environmental and climatic regimes. The imagery was used to derive an orthomosaic and digital elevation model that could be used to measure road infrastructure and landscape change over time (e.g., fish habitat). The RPAS missions were conducted with a Griffon SeaHunter and full-frame DSLR sensor and scoped to obtain <10 cm spatial resolution imagery along a combined 396 linear km. The final deliverables covered over 22,000 ha and 29,000 ha for the ITH and Dempster Highways, respectively, and represent one of the first non-military beyond-visual-line-of-sight RPAS data products of its kind and scale in Canada, and likely elsewhere. At the time of collection the data constituted the most current and detailed photo surveys of two of Canada’s most northern highways constructed over ice-rich permafrost terrain, and will provide a valuable baseline to study past and future landscape change. 2022-08-05 Fisheries and Oceans Canada info@dfo-mpo.gc.ca Economics and IndustryForm DescriptorsRPASdronearcticinfrastructureelectro-opticalanthropogenic disturbancepermafrostdigital terrain modelGeographic dataAerial photographyGeomaticsRemote sensingDigital elevation data Data DictionaryPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/Data%20Dictionary_Dictionnaire-de-Donn%C3%A9es_HW8_2019_Tiles.pdf Hwy8_Dempster_Orthomosaic_Tiles_2019ESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Hwy8_2019_tiles/MapServer Dempster Highway Orthomosaic supplementary metadataPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/Metadata_RPAS_EN.pdf Dempster Highway Orthomosaic supplementary metadataPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/Metadonnees_RPAS_FR.pdf Long-endurance BVLOS RPAS missions for Arctic highway photogrammetric surveys: Mission planning and preliminary mapping resultsPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/CSRS%202020%20Saiet%20et%20al%20RPAS%20BVLOS%20ITH%20Dempster_EN.pdf Long-endurance BVLOS RPAS missions for Arctic highway photogrammetric surveys: Mission planning and preliminary mapping resultsPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/CSRS%202020%20Saiet%20et%20al%20RPAS%20BVLOS%20ITH%20Dempster_FR.pdf Hwy8_Dempster_Orthomosaic_Tiles_2019ESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/Hwy8_2019_tiles/MapServer Long-endurance BVLOS RPAS missions for Arctic highway photogrammetric surveys: validation and emerging applicationsPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/CSRS%202021%20van%20der%20Sluijs%20et%20al%20RPAS%20BVLOS%20ITH%20Dempster_EN.pdf Long-endurance BVLOS RPAS missions for Arctic highway photogrammetric surveys: validation and emerging applicationsPDF https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/CSRS%202021%20van%20der%20Sluijs%20et%20al%20RPAS%20BVLOS%20ITH%20Dempster_FR.pdf Hwy8_Dempster_Orthomosaic_2019ESRI REST https://tiles.arcgis.com/tiles/frg4OAcWxey830S0/arcgis/rest/services/Hwy08_Dempster_2019_07_30/MapServer Hwy8_Dempster_Orthomosaic_Tiles_2019SHP https://pacgis01.dfo-mpo.gc.ca/FGPPublic/Hwy8_2019/Hwy8_2019_tiles.zip
