Hi Martin, Some edits for your consideration:
Submission type: Presentation Category: Developer Abstract: ------------------------------ -------------------------------------- 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 first SIS 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 a latitude and a longitude that is not sufficient for uniquely identifying a position on Earth, and demonstrate how Apache SIS can handle this part of the complexity for developers. Who the audience is and what we expect them to get: -------------------------------------------------------------------- This presentation is for anyone who wishes to utilize geographic data in their applications and would like to learn more about libraries that can simplify their development. Attendees can expect a big picture of standardization efforts, identify where some of the complexity stands, and how to hide it. In particular, we will compare the complexity of using an XML Schema Definition (XSD) available on-line to that of using UML as the source for application programming interfaces. Finally, attendees can expect an overview of test suites that may help them to increase their confidence in the georeferencing performed by their applications. How the content may help better the Apache and open source ecosystem: -------------------------------------------------------------------- Geospatial data are ubiquitous, but the difficulty of handling them accurately is often under-estimated. Many applications just handle latitudes and longitudes without realizing their ambiguity. This presentation will hopefully help to improve awareness about standards, encourage participation in implementation-neutral efforts like those available from OGC and GeoAPI interfaces, encourage existing application developers to use available test suites, and encourage participation in the improvement of those implementation-neutral test suites. Lastly, we hope to raise interest in Apache SIS as a powerful tool for implementing standards based geospatial development and testing.
