xcube-4d-viewer 1.0.9

API extension to the xcube server allowing cubes to be viewed in the Earthwave 4D viewer.

xcube_4d_viewer

This repository is a plugin for the xcube server.

xcube (https://xcube.readthedocs.io/en/latest/overview.html) is a Python package for generating and exploiting data cubes powered by xarray, dask, and zarr. It also provides a web API and server which can be used to access and visualise these data cubes.

This repository serves as an API extension to the xcube server, allowing xcube data cubes to be analysed and visualised within Earthwave's 4D viewer. It computes configuration details and heatmap/3D heatmap/terrain tiles from the server's data cubes and provides them in a format expected by the 4D viewer.

In order to connect to Earthwave's 4D viewer, the API extension needs to know the address of Earthwave's Middle Tier service, and the xcube server using the extension needs to be externally accessible. Therefore, to make use of the API, two additional keys must be set in the server config file:

• ServerExternalURL - the externally accessible URL of the xcube server. This should be set up by the user through a tool such as nginx.
• MiddleTierURL - the current URL of the Middle Tier service. Please contact [e-mail] for this information.
