Google Earth London – Level of Detail/Network Links

By Google Earth, Movies 10-20

Loading large city models requires intelligent data management and loading structures, especially in the case of Virtual London where the model now extends to over 2000 Km in extent. To manage the data, Richard Milton here at CASA has written a KML file to use the Network Link function of KML and Level of Detail to intelligently load in Google Earth files depending on the users’ viewpoint. The movie below demonstrates this tile loading ability:

All of London’s 33 Boroughs are included in the file structure allowing a seamless flythough of the 3D data. Due to ongoing licensing issues this will only currently be available on computer systems run internally within the Boroughs – but it provides an insight into how the work is progressing…

Google Earth Paper Models

By 3D Modelling, Google Earth

Google Earth is about data, to construct 3D models of cities you need data on heights and textures. In our post on Canary Wharf we point to how the model was constructed using Emporis as a reference. Another route however is to look at paper models and Skyscrapermodels.us by John Townsend is an excellent resource. The site provides full plans of a number of notable skyscrapers which are designed to be printed out onto card or paper and folded to construct the geometry.

Pictured above are the plans designed by John for the Bank of China in Hong Kong. Our cutting and glueing skills are quite frankly limited but by placing the texture in SketchUp you can cut and fold digitally. Combine this with the ability of Google Earth Beta 4 to import textures and you can quickly create a 3D model which can be exported and viewed in context.

Our model of the Bank of China was made by simply tracing the outline in Google SketchUp for each section and rotating (folding) along the lines as indicated in the drawing. We would be interested in any other models made this way as there are a numerous paper model folding sites on the web.

You can download the model of the Bank of China here (168K)

London MonoMetro 2012 Visualising the City

By Posts

Just out on YouTube is a link to MonoMetro a proposal for a new rapid transit system in London. The info on MonoMetro makes its clear that its not a Mono Rail system but a narrow gauge mono-path railway…

To be honest we cant see it working but the movie displays a good use of a real world video and digital overlays to visualise the proposed impact of the MonoMetro system. It also illustrates how much of a visual impact the system would have on London and for that reason alone its probably a non-starter..
