First call for participation: “Workshop Virtual Globes or Virtual Geographical Reality: How much detail does a digital earth require?”

Dr Arzu Coltekin from our working group and Professor Keith Clarke, University of California, are organising a ASPRS/AutoCarto 2010 Workshop, November 16th, 2010, Orlando, Florida, USA:

This workshop brings together experts from different yet related areas of geographic sciences, visual analytics and information visualization with the aim of producing a research agenda for level-of-detail (LOD) and information display-related issues for geovirtual environments (GeoVEs) and virtual globes. Many aspects from production to visualization and semantics will be covered.

Topics: (but not limited to):

. Theories and Vision of Digital Earth
. Data Acquisition and Sources
. Data Integration (Multiple Sensors, VGI and ‘formal’ data)
. Modeling, Simulation, Visualization
. Level of Detail and Information Density
. Visual Complexity and Visual Analytics
. Display Types (Small and Large Displays, 2D and 3D Displays, Limitations,
. Users and Applications of GeoVEs and Digital Globes

3D object library – 145 new landscape objects available

The Victoria Resources Online (VRO) 3D object library now provides a greater range of landscape objects for download. These objects are categories as either (i) vegetation, (ii) animals, (iii) built structures, (iv) rural landscapes. The models are free for use and available in a range of file formats including *.obj, *.dae, *.3ds, *.SKP and *.png. Recently the team (Falak Sheth, Matthew Cox and Wayne Harvey, members of our working group) have added and additional 145 objects, comprising a mixture of 2.5 and 3D objects. Feel free to download these objects and to create your virtual worlds. We would also be most interested to hear about any visualisation products you create using these objects.

Sony’s new way of looking at 3d Displays

New way of looking at 3d Display

The 13 x 27-cm device packs a stereoscopic, 24-bit color image measuring just 96 × 128 pixels viewable at 360-degrees without special glasses. If the prototype ever hits the assembly line then Sony envisions its commercial use in digital signage or medical imaging — or as a 3D photo frame, television, house for your virtual pet, or visualizer to assist with web shopping in the home.

Geographical Visualization papers from the Joint International Conference on Theory, Data Handling and Modelling in GIS

A series of refereed papers on Geographical Visualization were presented at the Joint International Conference on Theory, Data Handling and Modelling in GeoSpatial Information Science, Hong Kong 26-28th May. Titles and authors of these papers are available in our publication section.

Apple exploring interactive, glasses-free 3D holographic displays.

As 3D is pushed as the next big thing in Hollywood films and home theater, Apple has show interest in a three-dimensional interactive experience that would allow multiple users to manipulate holographic 3D objects in space without the need for special glasses or headgear.

Bing Maps incorporates Photosynth models.

Microsoft Photosynth is a photogrammetric software that creates 3d buildings from multiple photos, e.g. shot by random tourists. Our colleagues from the urbandigital blog are very much in favour of Photosynth and see great potential in it for urban visualization or as a kind of 3d scanner. Now, Microsoft has taken the logic next step and integrated Photosynth with Bing 3D. It may be criticized that the Microsoft approach requires Silverlight which is still not standard. However, Bing users can now create buildings automatically from photos whereas Google Earth users are modeling their content in Sketchup.

Improving Data Visualisation for the Public Sector

The Improving data visualisation for the public sector project undertaken in the United Kingdom provides an excellent resource of case studies, tools, step by step instructions for creating visualisation products. The site includes tools and examples of both information and geographical visualisation which can improve access to data and ultimately assist government in its decision-making processes. This is a great practical resource.
