Open Geospatial Standards and Open Source - George Percival, Open Geospatial Consortium (OGC)
The aim of this talk and the geospatial track is to increase the benefits of implementing open source consistent with open geospatial standards. Open standards capture geospatial knowledge gained from previous experience for reuse. Accuracy in data exchange is increased by using standards. Even “simple” use cases done inconsistently cause errors, e.g. coordinate order. Standards from the Open Geospatial Consortium (OGC) applicable to Apache projects include: coordinate systems, geometry, grids, spatial relations, web services, encodings, metadata. Multiple Apache projects include geospatial implementations as highlighted in this track. To aid in code refuse this track seeks to increase coordinations across Apache projects based on geospatial standards as well as with other external activities. An anticipated outcome of this track is increasing geo-collaboration of Apache and OGC.

Applying Geospatial Analytics Using Apache Spark Running on Apache Mesos - Adam Mollenkopf, Esri
This session will explore how to apply spatiotemporal analytics using Apache Spark on high velocity streaming data-in-motion and high volume batch data-at-rest. A comparison of available open source geospatial libraries will be reviewed including Apache SIS, Magellan, JTS, and the esri/geometry-api-java. Demonstrations will be shown on how to integrate a geospatial library with Spark analytics and how these analytics can be run on an Apache Mesos cluster to provide a highly scalable solution with elastic capabilities. Examples will focus on applications in the connected car space and smart cities and smart communities.

SciSpark: MapReduce in Atmospheric Sciences - Kim Whitehall, NASA Jet Propulsion Laboratory
The atmospheric science (AS) community generates model and observational data to simulate and monitor the Earth system. Big data in the AS community has arrived: high volumes (petabytes), at increasing velocity (to AS groups worldwide) and variety (of data formats and resolutions), are need for the veracity of models and observation systems that add value to the policy-making process. As scientists require solutions that allow interaction with these big data, the community is interested in the Map Reduce paradigm and Apache Spark. This talk presents a specific NASA Advanced Information Systems Technology (AIST) project called “SciSpark” that marries Apache Spark with climate science. SciSpark is a scalable system for interactive AS analysis. We will demonstrate SciSpark’s scientific data ingestion, visual interaction and metrics generation using the Spark engine.

Geospatially Enable Your Hadoop, Accumulo, and Spark Applications with LocationTech Projects
What is the average predicted temperature of BC from 2050-2099 based on forecasting models? How many tweets containing the hashtag #apachecon were sent from Canada? In general: how do we ask questions concerning location to very large sets of geospatial data? To answer these types of questions, existing large data processing frameworks like Hadoop, Accumulo and Spark need to be "geospatially enabled". LocationTech is a working group inside of the Eclipse Foundation that is home to 4 open source projects doing exactly that: GeoTrellis, GeoWave, GeoMesa, and GeoJinni (sense a pattern?). In this talk, I will give an introduction to what geospatial data is, talk about challenges in processing large sets of geospatial data, and talk about how these four LocationTech projects work with Apache projects to overcome those challenges and let us get the most out of our large geospatial data.

Hiding Some of Geospatial Complexity - Martin Desruisseaux, Geomatys
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.

Geospatial Querying in Apache Marmotta - Sergio Fernandez, Redlink GmbH
Apache Marmotta provides different means of querying: SPARQL, LDPath, LDP, etc. GeoSPARQL provides an extension to the SPARQL constructs to represent and query geospatial data. The talk will present the development recently done to add GeoSPARQL support in Marmotta, going through the challenges and potential of this new set of features, demoing some of then during the talk.

Crowd Learning for Indoor Positioning - Thomas Burgess, indoo.rs GmbH
Real-time accurate indoor positioning poses many new possibilities and challenges. At indoo.rs (Austrian based start-up founded in 2010), we enable positioning within mobile applications (Android/iOS) so that users can find themselves and navigate through floor plans. In practice, we estimate location and movement, using motion sensors and comparisons of radio scans (WiFi/iBeacon) to pre-measured reference measurements (fingerprints). We currently are transitioning from using dedicated measurements to an approach that learns and updates references by analyzing data from navigating users.This approach uses the Hadoop ecosystem to combine the output of the IOT network of mobiles and beacons with big data based machine learning and near real-time analytics (including visualizations). The complete solution reduces implementation and maintenance cost of installing indoor location.
