Description

  • New layers:
    • "Geophysics/World Digital Magnetic Anomaly Map" available in QGreenland Custom (QGIS plugin)
    • "Geophysics/Albedo":
    • July 2018 albedo (1km)
    • July 2019 albedo (1km)
    • "Geophysics/Heat flux/Flow from multiple observations (55km)"
    • "Geophysics/Heat flux/Flow measurement locations"
    • "Oceanography/Bathymetry/Depth contours"
    • "Geology/Geological map/Ice thickness contours"
    • "Sea ice/Monthly mean concentration (25 km)/September (min monthly extent)/September 2021"
    • "Sea ice/Monthly mean concentration (25 km)/Feb or March (max monthly extent)/March 2021"
  • Updated layers:
    • "Earthquakes" updated to include 2021 data
    • "Sea ice / Monthly Mean Concentration (25km) / Feb or March (max monthly extent)" updated to include 2021 data
    • "Reference/Borders/Global coastlines" updated to use GSHHG dataset instead of Natural Earth.
    • "Reference/Latitude lines": Resolve issue with clipping of latitude reference layers
    • "Basemaps/Background (500m)": Use JPEG compression to significantly reduce file size
    • Remove "Monthly sea ice extent (1978 - present)" (time-series, online-only).
    • Convert RACMO promice mask layers to Byte data type.
    • Update Bedmachine dataset metadata to reflect new v4 data.
    • Convert "Likely basal thermal state June 23 1993 - April 26 2013 (5km)" layer to Int16 data type.
    • "Regional climate models/RACMO model output/Runoff 1958-2019 (1km)": change colormap, make 0 values transarent.
    • "Reference/Timezones": add labels.
    • "Reference/Borders/Greenland coastlines": update style to remove green tint.
    • "Geology/Earthquakes M above 2.5 1900-2020": show all earthquakes in background boundary instead of subsetting to region around Greenland.
    • "Reference/Longitude lines": display positive degrees West instead of negative.
    • "Hydrology/Inventory of marginal lakes"
    • "Monthly sea ice extent (1978 - present)" (time-series, online-only)
    • "Glaciology/Glacier terminus positions 2000-2021" layers to use NSIDC-0642 V2 (released Oct. 2021). Add layers for 2017-2021 winter seasons.
  • Moved layers:
    • "Geophysics/Geothermal heat flux (5km)" layer to "Geophysics/Heat flux/Flux from ice cores (Greve, R.) (5km)".
    • "Oceanography/Bathymetric chart of the Arctic Ocean (400m)" layer to "Oceanography/Bathymetry/Depth (400m)"
    • "Human activity/Research stations" group to "Human activity/Research sites"
    • REMOVED from QGreenland zip package; available via QGreenland plugin:
    • "Glaciology/Ice sheet velocity/ITS_LIVE"
    • "Terrain models/Arctic DEM"
  • Remove online layers from the QGreenland Custom QGIS plugin manifest. Once support for online layers is added to the plugin, online layers will be re-added to the manifest file.
  • Add metadata.txt with layer information to layer data directory. This allows users who are not using the QGreenland project to access e.g., the layer's abstract and citation information.
  • Upgrade GDAL version used for running layer pipelines to v3.4.0
  • Update .txt documentation in the package (e.g. README.txt) to rich HTML documentation.
  • Remove most WMM layers from core package. Retain dip poles, main field declination, and blackout zones layers.
  • Improve raster compression.
  • Add scalebar to map viewport in lower-right corner.
  • BREAKING: minimum supported version of QGIS is now v3.16.
  • New Time Controller allows visualization of time-series layers.
  • Overhaul YAML configuration to Python configuration.
  • All processing steps are now expressed in configuration.
  • Add provenance information to QGIS Layer Properties "History" tab.
  • Update and improve documentation for v2.0.0
  • Remove UserGuide.pdf and MakingDataQGRCompatible.pdf in core zip package, information in these documents is now represented in UserGuide.pdf
  • Switch back to .qgs project file from .qgz; There is https://github.com/qgis/QGIS/issues/42033 conveniently opening .qgz project files in OSX for some versions of QGIS 3.16.x.
