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. Update the BedMachine dataset ("Terrain models/BedMachine") to v5, which was released in September 2022. 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. 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data/Topographic map of Greenland" "Internet-required data/Satellite orthophoto mosaic (10-0.2m)" Remove outdated "Terrain Models/Topographic map (1 to 500,000)" layer from the Danish Agency for Data Supply and Infrastructure (SDFI).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. 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 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 -> ...
