The processing pipeline

In general, a data-processing pipeline looks like this:

  • Fetch input assets

  • Run layer pipelines, writing outputs to final layer hosting locations.

  • For layers for which in_package is True, use hardlinks to link final layer ouputs to a QGreenland package compile location.

  • Create QGreenland package QGIS project file and other ancillary package files.

  • Zip the QGreenland package.

Contributing to the project

One of the primary goals of this project is to allow for scientists comfortable with standard GIS command-line tools to contribute new layers with as little friction as possible.

Contributing new datasets and layers requires writing simple Python objects containing the relevant data (metadata, download location, transformation steps) needed to include the layer in QGreenland.

Currently, layer styles can be contributed without any programming knowledge by designing the style in QGIS, saving it as a .qml, and committing it to the qgreenland/ancillary/styles directory.

You can contribute to this project even if you do not have write access by forking, making your change, making all CI checks pass, then opening a Pull Request. Learn more:
