From Sky to Earth: Data Science Methodology Transfer

We describe here the parallels in astronomy and earth sciencedatasets, their analyses, and the opportunities for methodology transfer from astroinformaticsto geoinformatics. Using example of hydrology, we emphasize how meta-data and ontologies are crucial in such an undertaking. Using the infrastructure being designed for EarthCube - the Virtual Observatoryfor the earth sciences- we discuss essential steps for better transfer of tools and techniques in the future e.g. domain adaptation. Finally we point out that it is never a one-way process and there is enough for astroinformaticsto learn from geoinformaticsas well.
