ApacheCon North America 2014

Apache Spatial Information System (SIS) is a Java library for developing geospatial applications which conform to international standards. SIS implements interfaces derived from UML published jointly by the Open Geospatial Consortium (OGC) and the International Organization for Standardization (ISO). This presentation will introduce the OGC vision, the benefits of  standards, the GeoAPI approach of using interfaces to support standards, and the Apache SIS implementation of those interfaces as well as future roadmap. This presentation will focus on metadata (ISO 19115) and georeferencing by coordinates (ISO 19111). We will give a quick introduction to geodesy, in particular examining a common pitfall of only specifying (latitude, longitude) that is not sufficient for uniquely identifying a position on Earth, and show how Apache SIS can handle this part of the complexity for developers.
