The intent is to make a free trafic solution!<br/><br/>I think from my toughts, that some sort of free programing solution of how cars should interact in traffic should be built.<br/>As when to stop or go, or don’t crash.<br/><br/>The free solution is to make lines, and adapt the objects to Path constrain, and animate them, from here to there… Tricky but you can do it…

Aimsun ( is a traffic simulation package that offers good integration capabilities, including a comprehensive SDK. Maybe it will be possible to combine it with CityScape, CyberCity 3D, Maya or 3DSMax.

In general we know how to model buildings, thats not too tricky – ours in the render are simply placement models for the street network. <br/><br/>The tricky part is modeling traffic simulation within a city model using software that is not at the $$$ level

Geodemographics, Visualisation, and Social Networks in Applied Geography

This review begins by acknowledging the success of geodemographics as an important area of activity in applied geography. However, it then develops a critique of the conceptual and computational underpinnings of the approach, and argues that changes in data supply and online communication have rendered current practices obsolete. It presents elements of a new perspective, entailing: changes in the specification, estimation and testing of online geodemographic systems; adoption of consultative practices from online folksonomies; automated generation of pen portraits; and

SpatialKey looks a promising new GIS based start up built around geovisualisation. Of particular note are the heat map visualisation demos which link both time and place.

It appears to be built in the new Flex framework which I think w…

I have always struggled to find a nice easy way to create cartograms. That was until I found a relatively new tool called ScapeToad ( Within minutes I had generated a very appealing cartogram of London at Output …

Web Mapping 2.0: The Neogeography of the GeoWeb

Haklay, M., Singleton, A.D., Parker, C. (2008) Web Mapping 2.0: The Neogeography of the GeoWeb. Geography Compass.


The landscape of Internet mapping technologies has changed dramatically since 2005. New techniques are being used and new terms have been invented and entered the lexicon such as: mash-ups, crowdsourcing, neogeography and geostack. A whole range of websites and communities from the commercial Google Maps to the grassroots OpenStreetMap, and applications such as Platial, also have emerged. In their totality, these new applications represent a step change in the evolution of the area of Internet geographic applications (which some have termed the GeoWeb). The nature of this change warrants an explanation and an overview, as it has implications both for geographers and the public notion of Geography. This article provides a critical review of this newly emerging landscape, starting with an introduction to the concepts, technologies and structures that have emerged over the short period of intense innovation. It introduces the non-technical reader to them, suggests reasons for the neologism, explains the terminology, and provides a perspective on the current trends. Case studies are used to demonstrate this Web Mapping 2.0 era, and differentiate it from the previous generation of Internet mapping. Finally, the implications of these new techniques and the challenges they pose to geographic information science, geography and society at large are considered.

I think you’re correct in identifying the problem that people would think that air above the 3D construction is ‘safe’. Personally (and as usual 🙂 ) I think a 2d color map layer would work just fine. I’d bet you could find users who look at your map and think that the areas between the roads are ‘safe’, I assume they are just unsampled?<br/><br/>A possible improvement would be to produce a set of tubes over each road which are colored. This would give the advantage of making the roads stand out, give the impression that only the roads are sampled and get over the issue of ‘high air being clear’.<br/><br/>Do keep experimenting though!<br/><br/>Rich
