Build Status Codecov

Parts of the linked Earth data demonstrator which sit between the DGGS and the user-facing app.

Guide to this repo:

  • pom.xml and .travis.yml are used for continuous integration; the pom.xml really just wraps dynamic-store/pom.xml to make Travis easier to use with this repo.
  • batch-demo/ has an old prototype of the stack which we are working on at the moment, which only did offline RDF materialisation for Landsat data
  • dynamic-store/ contains the new implementation we're working on, which can generate RDF triples from Landsat data on the fly, and doesn't have to make those triples persist (huge space saving!).
  • scripts/ is for development utilities which don't belong anywhere else.

Caveats

We don't currently implement any spatial predicates, but when we do there will likely be more "gotchas" to list here (e.g. crossing the dateline, behaviour in polar regions, etc.)
