Geospatial Data Extraction Tool

The Geospatial Data Extraction Guide can be found here. The Geospatial Data Extraction Tool allows for the dynamic extraction of data from the Government of Canadas Open Data Portal. There is a selection of base layers including: Landsat mosaic Canadian Digital Surface Model Canadian Digital Elevation Model National Forest Inventory National Tiling System Grid Coverage National Parks Boundaries National Marine Conservation Areas Automatic Extraction Building Projects Limits The User can select the data to be extracted, including: CanVec Elevation Automatic Extraction Data CanVec CanVec contains more than 60 topographic features organized into 8 themes: Transport Features, Administrative Features, Hydro Features, Land Features, Manmade Features, Elevation Features, Resource Management Features and Toponymic Features. This multiscale product originates from the best available geospatial data sources covering Canadian Territory. It offers quality topographic information in vector format complying with international geomatics standards. The document CanVec_Code in the Data Resourced section shows the list of entities and the scales at which they are available. The maximum extraction area is 150000km. Users are able to extract the following data: Lakes and rivers - Hydrographic features Transport networks - Transport features Constructions and land use - Manmade features Mines, energy and communication networks - Resources Management Features Wooded areas, saturated soils and landscape - Land features Elevation features Map Labels - Toponymic features (50K only) Output Options: OGC GeoPackage, ESRI file Geodatabase, ESRI Shapefile Coordinate System Options: NAD83 CSRS (EPSG:4617), WGS 84 / Pseudo-Mercator (EPSG:3857), NAD83 / Canada Atlas Lambert (EPSG:3979) Option to clip the data: Yes / No Scale Options: 1 / 50,000, 1 / 250,00 Elevation Elevation data consists of the Canadian Digital Elevation Model (CDDEM) and the Canadian Digital Surface Model (CDSM). These products are available for extraction along with their derived products (Shaded Relief, Color Shaded Relief, Color Relief, Slope Map*, Aspect Map* and Point Data). *Only available for CDEM. The maximum extraction area is 50000km. Users are able to extract the following data: Digital Elevation Model (DEM) Shaded Relief Color Relief Color Shaded Relief Slope map Aspect map Point Data Pick an azimuth between 0 and 360 Degrees: Direction of light source, between 0 and 360, measured in degrees, clockwise from the north. Pick an altitude between 0 and 90 degrees: Vertical direction of light source, from 0 (horizon) to 90 degrees (zenith). Enter a vertical exaggeration factor: Vertical exaggeration factor. Select the slope's measuring unit: Choice of degrees or percent slope. Coordinate System Options: NAD83 CSRS (EPSG:4617), WGS 84 / Pseudo-Mercator (EPSG:3857), NAD83 / Canada Atlas Lambert (EPSG:3979). Data is stored in geographic coordinates (longitude and latitude). However, it can also be offered in a plane coordinate projection (X and Y) at the time of extraction. Definition for the coordinate system can be found in the metadata. Select the DEM output formats: OGC GeoPackage, ESRI file Geodatabase, ESRI Shapefile. The source data (DEM or DSM) available formats are GeoTIFF and Esri ASCII Grid. The GeoTIFF format specification can be obtained from: https://www.pubdoc.org/fileformat/rasterimage/tiff/geotiff.pdf and https://geotiff.maptools.org/spec/geotiffhome.html. The Esri ASCII Grid format specification can be obtained from:https://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/esri-ascii-raster-format.htm Select the Point Data output format: ASCII Gridded XYZ (xyz), ASCII Gridded CSV (.csv). The Point Data available formats are text CSV (.csv) (comma separated values) and text XYZ (.xyz) (space separated values). The format specification is the same for both (ASCII Gridded XYZ) and can be obtained from: https://www.gdal.org/frmt_xyz.html Select the image resolution: 0.75 arc seconds, 1.5 arc seconds, 3 arc seconds, 6 arc seconds, 12 arc seconds Email address ([e-mail]): When processed results will be deposited to the given email.
