A QGIS 3 processing plugin to query and return data in GeoTIFF format from an Open Data Cube.

The Data Cube plugin is a processing plugin as opposed to a docked or panel type plugin. This was done to reduce PyQt UI development, but it is a little restrictive for future development (of user interface features).

There is scope to add more tools (processing algorithms) to the toolbox (provider). This can be done by writing a datacube_query.algs class that subclasses datacube_query.algs.__base__.BaseAlgorithm, importing that class in datacube_query.provider and appending the class to datacube_query.provider.DataCubeQueryProvider.algs.

There are some make files (win and *nix) to run tests and build a zipped plugin and/or static docs.

make        # default target, will run make clean, make doc and make build
make build  # build the plugin from the current source tree
make doc    # build the static docs
make clean  # explicitly clean up the source tree
make test   # run the tests

There's no API documentation as such. The plugin code is only meant to be used from a GUI, but the code is fairly well commented. The user docs are static HTML included with the zipped plugin file, and also are automatically built at datacube-qgis.readthedocs.io from a commit hook to the github repo.

There isn't a great deal of QGIS 3 plugin development documentation yet. Some links below:

• QGIS Python API
• QGIS Plugin Builder plugin (qgis3 source version, not released on QGIS Plugins repo)
• QGIS processing algorithm porting guide
• Plugin migration to QGIS 3
