Apache: Big Data 2016

It is tempting to ignore the complexity of geospatial international standards on the assumption that everyone today uses coordinates given by GPS. But even though obsolescent, the NAD27 datum for instance is still critically important in the U.S. where it has been used for definitions of many legal boundaries. Even on modern datum, support of polar areas or supplemental dimensions can be challenging. In this talk, we will present a few key Apache SIS methods that handle a lot of this complexity: e.g. how to get Coordinate Reference Systems from strings and an estimation of transformation accuracy, through an API that avoid diving too deeply in the complexity of GIS. We will show an example of what happen under the hood during a cube transformation, for demonstrating what the developers gain with SIS. Finally, we will present applications for trying Apache SIS without programming.
