Abstract
This presentations showcases the latest advances on building a full 3D Open Source GIS software stack.Some important cities have recently released their 3D models of textured buildings as Open Data : Bordeaux and Lyon in France, Geelong in Australia or Berlin in Germany among others. Meanwhile, new hardware and sensors for 3D data capture and interaction. We want to be able to store, analyze and visualize both 2D and 3D data with same Open Source tools.Among the processing we want to use 3D intersection, 3D Union, triangulation and a lot of other spatial analysis functions we already use in 2D. Other types of 3D data also need to be stored and processed like 3D Point clouds from Lidar data, or DEMs.With 3D data, an absolute must-have is a nice, fast and smooth rendering of features, and their associated textures. Visualization is a key element of a complete vertical software stack of 3D data management.This presentation will demonstrate the ability to setup and take advantage of a full FOSS4G 3D stack. This stack features various components, just like a 2D GIS stack.PostgreSQL and PostGIS now feature 3D data storage and processing GIS servers can now stream the data with Web Services Desktop applications allows 3D visualization ( QGIS and Horao plugin) WebGL application let the user configure a native browser 3D visualization These components improve over time, allowing more capabilities, be it for the analysis part in the database, or the visualisation part in the browser.
