FOSS4G North America Conference 2013 Preliminary Program

Say Hello to OpenLayers 3
Eric Lemoine, Camptocamp SA and Tim Schaub, OpenGeo
We've rewritten OpenLayers from the ground up with the goal of offering a powerful,
high­performance library leveraging the latest in web technologies. This talk will take you on a
high­level tour of OpenLayers 3. We will present how OpenLayers 3 fits into the current suite of
open­source web mapping tools and help you decide when to use OpenLayers 3 for your
applications.
OpenLayers adopts a flexible architecture that enables using different rendering technologies.
For example, OpenLayers 3 may use WebGL on modern desktop browsers, Canvas 2D on
mobile browsers, and DOM on less capable browsers. We believe this architecture makes
OpenLayers 3 a good choice for many types of applications and use­cases.
OpenLayers has always provided a broad range of functionality for accessing raster and vector
data from a variety of different sources. In this talk we'll describe the tools that we're making
available with OpenLayers 3 that let you build a compact and optimized build of the library with
just the components that you need.
Big map players are also adopting WebGL as the technology for displaying maps in web pages.
In this talk we will discuss what WebGL offers for maps, looking at both 2D and 3D. We, for
example, expect to use WebGL to display millions of vectors, and effectively reproject vector and
raster data.
Lastly, we will present the current status of the development, and the next steps.
OpenLayers 3: Under The Hood
Eric Lemoine and Tom Payne, Camptocamp SA
OpenLayers 3 is the next generation of web mapping. A radical new architecture and the use of
cutting edge JavaScript techniques, libraries, and tools enables a full suite of previously
unimaginable functionality while maintaining a compact, high performance library.
In this talk we'll show you how to use this functionality in your applications, and peek under the
hood to see how OpenLayers 3's architecture makes it possible. We'll include:
Virtual globe (Cesium) integration: a carefully designed camera and data source abstractions
permit close integration with the virtual globes. Switch between 2D and 3D views of the same
data, or display synchronized 2D and 3D views side by side.
Multiple rendering back­ends: a pluggable rendering architecture supports multiple renderers for
maximum performance and portability. A Canvas 2D renderer provides fast, reliable rendering on
current devices, a DOM renderer provides fall­back capabilities for older browsers, and a
WebGL renderer opens the door to the next generation of performance for the most demanding
