Layers

New

  • Add new "Places/Populated places" layer, replacing the "Places/Towns and settlements" layer.
  • Add new "Internet-required data/Geological Map (1:500 000)" layer from GEUS.
  • Add new "Geology/Mineral occurrences" layer from GEUS.
  • Add new "Glaciology/Ice sheet velocity" layers:
    • "GrIMP/Annual ice sheet velocity vectors 2021"
    • "GrIMP/Annual ice sheet velocity magnitude 2021 (200m)"
    • "GrIMP/Annual ice sheet velocity x component 2021 (200m)"
    • "GrIMP/Annual ice sheet velocity y component 2021 (200m)"
  • Add "Geology/Tectonic plates" polygon layer. This layer accompanies the existing "Geology/Tectonic plate boundaries" polyline layer from the same dataset.
  • Add new WMS layers from the Danish Agency for Data Supply and Infrastructure (SDFI):
    • "Internet-required data/Topographic map of Greenland"
    • "Internet-required data/Satellite orthophoto mosaic (10-0.2m)"
  • Add new "Internet-required data/Blue Marble shaded relief and Bathymetry (500m)" WMS layer from NASA Global Imagery Browse Services (GIBS)
  • Add new "Places/" layers from Asiaq/NunaGIS:
    • Buildings
    • Roads
  • Add new "Biology/Vegetation/Vegetation classification map (1km)" layer from the Raster Circumpolar Arctic Vegetation Map produced by Raynolds et al., 2019.
  • Add new "Oceanography/Seawater salinity (25km)" layers from the World Ocean Atlas 2023.

Updated

  • Fix descriptions of "Hydrology" outlets and basins layers.
  • Move "Hydrology" streams, outlets, and basisns layers from Mankoff et al. into "Streams, outlets, and basins" subgroup.
  • Rename "Places/Place names database" -> "Places/Points of interest". Towns and settlements are now excluded from this layer (in favor of the more-up-to-date "Populated places" layer.
  • Update the BedMachine dataset ("Terrain models/BedMachine v5") to v5, which was released in September 2022.
  • Fix title of BedMachine "ice thickness error" layer (remove /)
  • Update the geothermal heat flow dataset ("Geophysics/Heat flow (Colgan et al.)" layers) to v2.
  • Update "Sea ice/Weekly age (12.5km)" layers (2010-2020 -> 2011-2021)
  • Update "Sea ice/Monthly mean concentration (25km)" layers (2010-2021 -> 2011-2022)
  • Update the "Oceanography/Seawater temperature 2018 (25km)" layers:
    • Use the World Ocean Atlas 2023 Temperature data. These new layers are climatological averages between 1991-2020. Previous input data (WOA 2018) was an average for the years 1955-2017.
    • Update layer group name to remove "2018" ("Oceanography/Seawater Temperature 2018 (25km)" -> "Oceanography/Seawater Temperature (25km))"
    • Improve layer descriptions
    • Expand layer extent to QGreenland 'background' boundary.
  • Update the "Glaciology/Surface elevation change" layers to the latest version (v3) of the Climate Change Initiative (CCI) Surface Elevation Change dataset from the European Space Agency (ESA). This extends the timeseries to include a surface elevation change layer for 2016-2020.
  • Rename "Geophysics/World Magnetic Model/Dip poles" layer group -> "Geophysics/World Magnetic Model/Geomagnetic north pole"
  • Rename "Sea ice/Median extent" layer group -> "Sea ice/Median extent (1981-2010)"
  • Update "Oceanography/Bathymetry/Depth (400m)" layer to use the General Bathymetric Chart of the Oceans (GEBCO) Grid 2023, replacing the Bathymetric Chart of the Arctic Ocean (IBCAO) dataset. The GEBCO grid includes the IBCAO grid. This update includes the most recent data and expands the spatial extent of this layer to the QGreenland background boundary to make it consistent with other ocenaography layers.
  • Replace "Human Activity/Research sites/" layers related to PROMICE and GC-Net ("PROMICE automated weather stations", "Former PROMICE automated weather stations", "GC-Net automated weather stations") with one layer ("PROMICE and GC-Net automated weather stations") from a more up-to-date dataset provided by GEUS.
  • Improve symbology for "Regional climate models/RACMO model output/Annual mean wind vectors 1958-2019 (5km)" by removing color mapping to magnitude values. This was causing conflicts with other layers' color maps.

Removed

  • Remove "Biology/Fish/Arctic Char" layer.
  • Remove Humanitarian Open Street Map (HOTOSM) layers ("Places/Community map (crowd-sourced)"). These layers had innaccuracies and missing locations that we received feedback on. These layers were not considered usable.
  • Remove outdated "Terrain Models/Topographic map (1 to 500,000)" layer from the Danish Agency for Data Supply and Infrastructure (SDFI). Replaced by above mentioned "Internet-required data/Topographic map of Greenland" WMS layer.
  • Remove "Oceanography/Bathymetry/Depth contours" layer. This layer was pulled from the "Geological map of the Arctic / Carte gologique de l'Arctique" (Harrison et al., 2011) dataset and was provided with the geological data for additional context. It was derived from the (IBCAO) grid. Comparing this with the current IBCAO and GEBCO grids, these contours seem outdated. They also only cover a portion of QGreenland's background extent. Users can produce their own custom contour layer from the included "Oceanography/Bathymetry/Depth (400m)" layer using the Processing Toolbox (GDAL -> Raster extraction -> Contour).

  • Add "Geology/Tectonic plates" polygon layer. This layer accompanies the existing "Geology/Tectonic plate boundaries" polyline layer from the same dataset.
  • Fix descriptions of "Hydrology" outlets and basins layers.
  • Add new "Places" layers: "Towns" and "Settlements". These layers replace the previously removed "Towns and settlements" layer.
  • Rename "Places/Place names database" -> "Places/Points of interest". Towns and settlements are now excluded from this layer (in favor of the more-up-to-date "Towns" and "Settlements" layers.
  • Establish a more explicit/readable pattern for defining the order of QGreenland's layers and groups in the Layers Panel

  • Replace ArcticDEM layer task with generic Raster task.
  • Rename ReprojectRaster -> WarpRaster.
