WebGL Earth: open source 3D digital globe for web and mobile devices

Session Type: 
Tech Session
Presenter(s): 
Petr Pridal, Klokan Technologies
Petr Sloup

WebGL Earth is an open source software enabling exploration and zooming of a three dimensional virtual globe in any web browser on any platform including mobile devices, thanks to HTML5 WebGL standard.

This presentation demonstrates the capabilities of the project and shows new features: free camera movement, virtual terrain, visualization of custom raster and vector data, and rendering of 3d buildings.

The project is a free software available under standard GPLv3 license. Integration of WebGL Earth core with third-party applications and other open-source projects is possible. The source code is written in JavaScript using the Closure Library. The project is sustained through the support and cooperation of the developer community. We welcome anybody to contribute or just send feedback.

The status of GeoServer WPS

Session Type: 
Tech Session
Presenter(s): 
Andrea Aime, tech lead, GeoSolutions

This presentation will provide the attendee with an introduction to the GeoServer WPS 1.0 functionality. We will start by a brief introduction to the WPS protocol, show how GeoServer available functionality maps onto it, and show the support for quickly building WPS requests in a visual, form based environment.

We will then go though the current set of built-in operators, ranging from topologic analysis, simple statistical operations, raster to vector conversion, contour extraction, raster algebra, vector and raster “clip and ship”, georeferencing and various others.

The presentation will then move to the unique GeoServer integration features, showing how processing can seamlessly integrate directly in the GeoServer data sources and complement existing services, as well as integrate directly in the map rendering chain to provide on the fly data transformations such as on the fly contouring or point clustering.

The presentation will end with real world examples of applications using GeoServer WPS to do statistical analysis on crops, change visualization and web based image geo-referencing based on ground control points.

Speaker Bio: 

Andrea Aime has had long involvement in the open source community, first as a user and then as a core developer for the GeoTools and GeoServer project (and as a jai-tools contributor). Andrea's main interests cross through cartographic quality map rendering, spatial data analysis, performance and scalability as well as GIS programming and teaching.

Integration of GeoServer with NoSQL databases

Session Type: 
Tech Session
Presenter(s): 
Alan Mangan, Data Tactics Corp.
David Boyd, Data Tactics Corp.

This presentation will introduce a GeoServer Plugin for the NoSQL Mongo Database. Cloud-based data storage built around NoSQL document-oriented stores continues to grow, this plugin offers GeoServer-based visualization of geospatial data stored in MongoDB. The plugin allows a MongoDB instance with GeoJSON-encoded data to be used as a backing store for GeoServer. The plugin, developed in Java, is available under a GNU GPL v2 license.

The presentation will address the derivation of implied schema from a schema-less NoSQL store for use with GeoServer's Feature objects, handling type conflicts in document fields, performance issues calculating this schema for a new GeoServer Data Store, and the use of MongoDB's map-reduce to distribute the load when operating in a sharded cloud environment. Each MongoDB collection is generally stored as a separate GeoServer layer, although mixed-geometry collections can be split out into corresponding layers for visualization.

Speaker Bio: 
Mr. Mangan is Senior Software Developer at Data Tactics. He has a broad range of experience in software engineering and development; including scientific visualization, business intelligence, and middleware development.
 
Mr. Boyd is Director of Engineering and Research & Development at Data Tactics. He has over 30 years experience in geospatial development, and integrating and deploying complex data intensive systems. He has extensive involvement in the development and fielding of the Army Distributed Common Ground Systems. He also has considerable experience integrating, processing and exploitation of FMV, Imagery, and SIGINT as part of tactical, airborne, and shipboard implementations.

Map design, usability and interaction

Session Type: 
Tech Session
Presenter(s): 
Sergio Alvarez, Vizzuality
Javier de la Torre, Vizzuality

The geospatial world lacks of design, usability and interaction. Most of the map projects out there lack one single important thing, a story. Additionally the FOSS4G community is normally more focus on functionality that in careful design and user experience. In this talk we will present through examples how to design and develop mapping projects that tell you stories, maps that engage the user and drives them to their own conclussions. We will take the opportunity to explain also a typical workflow between Designers, Frontend developers and backend developers, all working to create great mapping experiences.

Speaker Bio: 

Javier de la Torre and Sergio Alvarez are founders of Vizzuality. They work with multiple international organizations helping them visualize large geospatial datasets. From humanitarian response projects to the World Database on Protected Areas or crowdsourcing climate change data.

The Intersection of Geospatial and Business Intelligence

Session Type: 
Tech Session
Presenter(s): 
Jesse Eichar, Camptocamp SA
Emmanuel Belo, Camptocamp

Business intelligence (the techniques used in identifying, extracting, and analyzing business data) is a massive market and a vibrant area of research and development for many companies. The incorporation of true geospatial data and analysis is still a new facet in the field and one that is expected to experience significant growth and evolution in the near future.

The goal of this talk is to discuss the current state of the open-source solutions, discuss the strengths and short comings of the current solutions and look at avenues for improvement and opportunity.

A few of the technologies that will be touched upon will include:

  • Olap4j
  • Geomondrian
  • Geowebbi
  • Spatialytics
  • Pentaho
  • Mondrian

Some axes of discussion:

  • Types of Queries
  • Types of Reports
  • Supported Standards
  • Supported Data Sources
  • Role in ecosystem
  • Interoperability
  • Architectures
  • Performance
Speaker Bio: 

For the last decade Jesse Eichar has been a professional open source advocate and developer. He one of the four uDig PSC, he is the maintainer of the Mapfish print module and the SecureOWS module, he is and has been a module maintainer of several GeoTools modules including, renderer, shapefile, GML, MIF, WFS and XML. He is a committer in Geoorchestra, Scala IO and sperformance projects as well as a contributer to Geonetwork, GeoServer and Apache Pdfbox.
