In+ersec+ion for Spatial People

Here's the recent open source / open data geonews in batch mode.

Software-related:

• On the iD Map Editor, the new OpenStreetMap editor, reached the Beta 1 state, if you want to see it in action, here's a nice 1-minute video
• It was mentioned in our press release section, but deserves additional attention, "GeoServer Beginner's Guide is a new book from Packt that teaches the readers to build custom maps using the dynamic real-time geospatial information. With the help of this book, readers will learn sharing of real-time maps quickly" Here's Jody's review of the book
• Via OR I learned about the release of Titan 0.3 which supports georeferenced data: "Titan is a highly scalable graph database optimized for storing and querying large graphs with billions of vertices and edges distributed across a multi-machine cluster. Titan is a transactional database that can support thousands of concurrent users."

I'm abroad this week, expect return to normal geonews coverage next week, thank you for your patience.

Slashdot discusses a story named Why Hasn't 3D Taken Off For the Web?

Their summary: "With HTML5 we're closer to the point where a browser can do almost everything that a native app can do. The final frontier is 3D, but WebGL isn't even part of the HTML5 standard, Microsoft refuses to support it, Apple want to push their native apps and it's not supported in the Android mobile browser. Flash used to be an option but Adobe have dropped mobile support. To reach most people you'd have to learn Javascript, WebGL and Three.js/Scene.js for Chrome/Firefox, then you'd have to learn actionscript + flash for the microsofties, then learn objective c for the apple fanboyz, then learn Java to write a native app for Android. When will 3D finally become available for all? Do you think it's inevitable or will it never see the light of day?"

We mentioned WebGL often lately, with many geospatial web tools betting on it.

Here's the recent geonews in batch mode.

On the open source front:

• 3D and open source with WebGL mixed with games gives you Voxel.js: Minecraft-like Browser-Based Games, But Open Source, which can certainly be reused for other geospatial projects

Every year, NORAD tracks Santa as he makes his trip around the globe on Christmas Eve. The NORAD Tracks Santa program is popular, receiving 19 million unique visitors last holiday season.

This year, as part of the NORAD Tracks Santa team, Analytical Graphics, Inc. used Cesium, an open-source WebGL virtual globe, to build a 3D web map for visualizing Santa’s location. The app goes live on December 24th at www.noradsanta.org. In the meantime, there is a tech write-up with screenshots showing the global terrain, imagery, and water. There are also instructions for making sure your computer will be able to run the app.

Here's the recent FOSS4G geonews.

In open source software updates:

• GEOS, the Geometry Engine Open Source, got to version 3.3.6
• The popular GeoServer got to version 2.2.2
• Another bug fix release is the OpenGeo Suite version 3.0.1
• It's not the end, GeoTools 8.4 was released

In the everything else category:

• Here's an entry on the GeoServer CSS module, that presents itself as an alternative and improvement over the SLD (Style Layer Descriptor) OGC standard: "GeoServer CSS is inspired by the web—and by great tools like Carto, Cascadenik, and MapCSS. Like these tools it provides a concise styling syntax modeled on CSS but differs in that it’s goal is to improve the experience relative to SLD while preserving CSS concepts like cascading. While we ultimately aspire to a common CSS-like styling language for web cartography, we hope that GeoServer CSS is much easier than SLD and will be familiar enough for web designers to use."
• Arnulf links to the SplashMaps Kickstarter project that uses open data, "real outdoors maps; based on open data, on light, weather friendly fabric" (image below)
• Geoff shares an entry on the Cesium open source WebGL virtual globe and mapping Javascript library, we mentioned Cesium before

• You heard of it already, but here's again on the topic, Why are we building OpenLayers 3?

The WebGL Camp provides WebGL developers a forum to present updates on their latest projects and frameworks. After five WebGL Camps in the USA, WebGL Camp is now coming to Europe being hosted by the University of Applied Sciences and Arts Northwestern Switzerland.

The agenda is online now and there are many geo visualization topics, for example Nokia 3D Maps, 3D building visualization, stereovision mobile mapping, CZML: the JSON schema for describing dynamic scenes in virtual globes (Cesium Globe), the OpenWebGlobe SDK for creating new virtual globe applications, and much more.

There is a new project on Github that has made a 3D view for OpenLayers!  It integrates AGI's new open source WebGL globe (Cesium) and uses the OpenLayers drawing & navigation tools to interact with the globe.  Support for WMS layers and feature importing are next on the to-do list.

A live demo can be found here:
http://jktaylor.github.com/openlayers/examples/adapters/editingtoolbar.html

The source code is available here.

At last week's 3D GeoInfo conference, I learned about the open source Glob3 3D GIS and Glob3 Mobile 3D virtual globe.

There isn't much on the sourceforge website: "glob3 is an open source 3D GIS multiplatform framework written in java with a very non restrictive license and advanced features." 

​But you'll get more on this page for Glob3 Mobile: "Glob3 Mobile is an open source 3D multiplattform virtual globe engine, running in mobile devices (Android and Apple) and in HTML5 web browsers. In this first version, it allows to connect to any OGC WMS public layer, and show it on the globe. Glob3 Mobile is also a framework for virtual globe development. It allows to write plugins directly in Javascript, and these plugins can run in the three plattforms (Android / Apple / web browsers). The project is currently in development, but first plugin examples can be tested in this site."

The apps for iOS and Android are free.

I was at the 3D GeoInfo 2012 conference last week and I learned about the DB4GeO / DB3D open source geospatial database, which is a Java object-oriented database focusing on 3D data. It supports CityGML, has a RESTful API and has its own WebGL visualization tool.

Since I failed to find much about it on the web other than the GitHub page (it seems the code wasn't synchronized for a while), let me serve you the abstract [pdf] of last week's presentation: "The analysis of complex 3D data is a central task for many problems in the geo- and engineering sciences. Examples are the analysis of natural events such as mass movements and volcano eruptions as well as 3D city planning and the computation of 3D models from point cloud data generated by terrestrial laser scanning for 3D data analysis in various domains. The volume of these data is growing from year to year. However, there is no geo-database management system on the market yet that efficiently supports complex 3D mass data, although prototypical 3D geo-database management systems are ready to support such challenging 3D applications. In this contribution we describe how we reply to these requirements advancing DB4GeO, our 3D/4D geo-database architecture. The system architecture and support for geometric, topological and temporal data are presented in detail. Besides the new spatio-temporal object model, we introduce new ideas and implementations of DB4GeO such as the support of GML data and the new WebGL 3D interface. The latter enables the direct visualization of 3D database query results by a standard web browser without installing additional software. Examples for 3D database queries and their visualizations with the new WebGL interface are demonstrated. Finally, we give an outlook on our future work. Further extensions of DB4GeO and the support for the data management for collaborative subway track planning are discussed."

I'd like to see the differences between PostGIS vs DB4GeO features in regards to 3D geodata. Is DB4GeO more and a playground for researchers?

The demo version of a potential 3D Viewer for geo.admin.ch - the geo-portal of the Swiss Confederation - is online at http://swiss3d.openwebglobe.org until July 31, 2012.

The 3D Viewer is based on the open source globe “OpenWebGlobe” using WebGL.

The scene convers entire Switzerland and is based on high resolution data from swisstopo: SWISSIMAGE, DHM25 and swissBOUNDARIES3D as well as extracts from swissBUILDINGS3D.

In addition, textured 3D objects from FHNW Muttenz and EPFL Lausanne are available. Outside the area with high-resolution data, Blue Marble from “NASA’s Earth Observatory” is used.

The total amount of texture and geometry data exceeds 2 TB and is being handled using the cloud from Amazon Web Services.

This demo has been developed by FHNW - University of Applied Sciences and Arts Northwestern Switzerland, camptocamp SA, the Federal Office of Topography, Switzerland, and geo.admin.ch.
