Surficial Geology This entry provides access to surficial geology maps that have been published in the Canadian Geoscience Map Series format. Three types of maps are available: 1)Surficial Geology: based on expert-knowledge full air photo interpretation (may include interpretive satellite imagery, Digital Elevation Models (DEM)), incorporating field data and ground truthing resulting from extensive, systematic fieldwork across the entire map area. Air photo interpretation includes map unit/deposit genesis, texture, thickness, structure, morphology, depositional or erosional environment, ice flow or meltwater direction, age/cross-cutting relationships, landscape evolution and associated geological features, complemented by additional overlay modifiers, points and linear features, selected from over 275 different geological elements in the Surficial Data Model. Wherever possible, legacy data is also added to the map.2)Reconnaissance Surficial Geology: based on expert-knowledge full air photo interpretation (may include interpretive satellite imagery, DEMs), with limited or no fieldwork. Air photo interpretation includes map unit/deposit genesis, texture, thickness, structure, morphology, depositional or erosional environment, ice flow or meltwater direction, age/cross-cutting relationships, landscape evolution and associated geological features, complemented by additional overlay modifiers, points and linear features, selected from over 275 different geological elements in the Surficial Data Model. Wherever possible, legacy data is also added to the map.3)Predictive Surficial Geology: derived from one or more methods of remote predictive mapping (RPM) using different satellite imagery, spectral characteristics of vegetation and surface moisture, machine processing, algorithms etc., DEMs, where raster data are converted to vector, with some expert-knowledge air photo interpretation (training areas or post-verification areas), varying degrees of non-systematic fieldwork, and the addition of any legacy data available.Each map is based on a version of the Geological Survey of Canada’s Surficial Data Model (https://doi.org/10.4095/315021), thus providing an easily accessible national surficial geological framework and context in a standardized format to all users.The "view on map" functionality provides a geospatial index of each published map, overlaid on a colour-coded map of Canada's surficial geological features described in the "Surficial geology of Canada" map (https://doi.org/10.4095/295462, 2014). Each geospatial polygon (footprint) points to a page in the Geoscan repository (Natural Resources Canada), each page displaying a link to a ZIP file which contains the map (PDF/JPEG), the corresponding geospatial data (raster images, shape files, legends) and possibly field data information. The geospatial index can also be downloaded as ESRI GeospatialDataBase (GDB) and MXD files. 2020-09-14 Natural Resources Canada nrcan.gscinfo-infocgc.rncan@canada.ca Form DescriptorsNature and EnvironmentScience and Technologyglacial featuresglacial depositsglacial landformstillssandsgravelsglaciolacustrine sedimentsglaciofluvial sedimentsorganic depositsalluvial sedimentscolluvial depositseolian sedimentslacustrine sedimentsmarine sedimentsglaciomarine sedimentsmorainessurficial geology/geomorphologyCanadaEarth sciencesGeologySurficial geology Surficial geology map indexESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/gsc_surficial_geology_en/MapServer Surficial geology map indexESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/gsc_surficial_geology_fr/MapServer Surficial geology map indexWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/gsc_surficial_geology_en/MapServer/WMSServer?request=GetCapabilities&service=WMS Surficial geology map indexWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/gsc_surficial_geology_fr/MapServer/WMSServer?request=GetCapabilities&service=WMS Surficial geology map index (File Geodatabase)FGDB/GDB https://ftp.maps.canada.ca/pub/nrcan_rncan/Surficial-geology_Geologie-des-depots-meubles/surficial_geology_index_geologie_surface/gsc_surficial_geology.gdb.zip Surficial geology map index (ArcMap project)MXD https://ftp.maps.canada.ca/pub/nrcan_rncan/Surficial-geology_Geologie-des-depots-meubles/surficial_geology_index_geologie_surface/gsc_surficial_geology_en.mxd Surficial geology map index (ArcMap project)MXD https://ftp.maps.canada.ca/pub/nrcan_rncan/Surficial-geology_Geologie-des-depots-meubles/surficial_geology_index_geologie_surface/gsc_surficial_geology_fr.mxd
