This tutorial will introduce you to the major features of TerriaJS and show you how to use it to build your own map applications for the web. Without writing any code or deploying anything, you will be able to offer your users a rich catalog of geospatial data to explore, and enable them to visualize it in 3D.
Australia’s NationalMap, nationalmap.gov.au, is an engaging, open-source web site enabling the public to discover and explore Australian government spatial data at the federal, state, and local levels. An interesting feature is that NationalMap does not host any data itself. Instead, it provides a federated interface to the diverse servers already operated by the the various government agencies, running Geoserver, THREDDS Data Server, ArcGIS Server, CKAN, Socrata, and many more.
This talk presents how to handle and visualize massive 3D city models with an open 3D GIS stack based on the OGC standard CityGML, the open source 3D City Database and its OGC Web Feature Service (WFS) interface, and the open 3D web-globe Cesium and its 3D Tiles specification.
OpenStreetMap and 3D visualization have been a goal of many for the past few years and there are numerous projects related to achieving this goal, each with various levels of success. With the advent of WebGL and Cesium as well as several new open formats, such as 3D Tiles; world scale, interactive, 3D visualization of OpenStreetMap on the web is finally within grasp.
From 2008 until recently, the proprietary Google Earth ecosystem was the primary tool for 3D geospatial visualization on the web. However, Google announced that support for the Google Earth API and Google Earth plug-in will be discontinued early in 2016. As a result, many developers have looked to open source and open standards as a replacement solution in order to avoid the vendor lock-in they endured in the past.
This talk presents the next big initiative from the Cesium team: 3D Tiles.
3D Tiles are an open specification for streaming massive heterogeneous 3D geospatial datasets, including 3D buildings, trees, point clouds, vector data, and terrain.
