- Add qgreenland.org and qgreenland github URLs in QGreenland's lower-left corner citation text.

- You no longer require a password to download QGreenland!
- Use
DEFLATE
compression for raster layers instead ofLZW
.DEFLATE
results in a good compromise between the QGreenland zip file size and the unziped package size. As of this release:- without compression:
- Unzipped size: 3.7G
- Zipped size: 631M
- with
LZW
compression:- Unzipped size: 867M
- Zipped size: 784M
- with
DEFLATE
compression:- Unzipped size: 653M
- Zipped size: 640M
- without compression:
- Add layer config CSV export utility script
- Add log analysis script: Download and byte count by QGreenland version
- Bugfix: layers not requiring earthdata login are no longer downloaded twice.
- Add LZW compression to all raster layers.
- New Oceanography layer: International Bathymetric Chart of the Arctic Ocean
- New Oceanography layer: IHO-IOC GEBCO Gazetteer of Undersea Feature Names

- Renamed 'Ice Sheet Mass Change' layer to 'Ice Column Thickness'
- QGIS project load speedup: remove internal colormap from sea ice concentration layers. Use .qml file to style these layers.
- Unscale sea ice concentration layers to percentages. Source GeoTiff files for sea ice concentration layers scaled values by 10 so that an internal color map could be used (GeoTiff files require integer-based lookup tables for color maps).
- Replace
ArcticDEM
layer task with genericRaster
task. - Rename
ReprojectRaster
->WarpRaster
. - Add Sea Ice Index layers:
- Median extent line layers.
- Sea ice min extent monthly concentrations.
- Sea ice max extent monthly concentrations.
- Re-organize, rename layers and layer groups to spec provided by Twila
- Add BedMachine "sources" from NetCDF datasets to layer descriptions
- Layers are collapsed by default. Previously, layers would be expanded to show their entire color maps by default. This took up a significant amount of screen space in the table of contents.
- Layers now have layer-specific description at the beginning of the tooltip, with additional dataset-level information following.
- Add BedMachine Error layer
- Add raster layer resolutions in parens after layer title
- Set "Land" layer to invisible so the background layer shows by default
- Move "Arctic DEM" layer above "Land" layer
- Label colormap entries with correct units/descriptions.
- Switch to
EPSG:3413
projection: Uses WGS-84 ellipsoid. - Enable all groups by default
- This way, everything is one click away -- enabling layers, hiding layers, hiding groups. If we want a layer to start invisible, we set that layer to invisible, not the group.
- Add new UngzipMany task
- Add GGD602 layer to
Geology & natural resources
layer group.
- Add 12.5km Circum-Arctic Map of Permafrost and Ground-Ice Conditions, Version 2 (https://nsidc.org/data/GGD318/versions/2) layer.

- Support layer titles in config
- Adjust group names
- Name files after the
layer_id

bumpversion
support to project as an invoke task.
- Configure the app so that when it runs in production it runs reproducibly by cleaning up its intermediate files aggressively.

run_task.sh
andcleanup.sh
toscripts/
dir. - README updates.
- Make layer and layer group visbility configurable.
- Make layer group expand/collapse state configurable.
- HACK: If the first layer in the legend is in a collapsed layer group, QGIS will automatically expand the layer group. Set coastlines layer to be first in the legend to avoid this.
- Add QGreenland logo and copyright text as QGIS decorations at bottom-left.
- Pre-compute statistics for raster layers so that QGIS can render those layers with the correct min/max values.
-
Add task to generate overviews for raster layers.
- Generate overviews for Arctic DEM layer.
-
Add VM configuration and update README on how to use VM to run tasks and serve data.
