A London Network Analysis using City Engine Monday 15th April 2013 at 13:07:00 by en-topia I thought i might try a very quick network analysis of central London using the new City Engine Graph analysis tool and the OS road network. In City Engine, Graph networks can be analyzed by computing global integration, local integration and inbetween centrality. Global integration refers to the sum of shortests paths between each road segment and all other selected segments Continue reading
Invisible fields Tuesday 19th February 2013 at 18:46:00 by en-topia The Washington Post recently released a front-page article claiming that "The federal government wants to create super WiFi networks across the nation...Cities support the idea because the networks would lower costs for schools and businesses or help vacationers easily find tourist spots. Consumer advocates note the benefits to the poor, who often cannot afford high cellphone and Internet bills."I will not comment on whether this is a true or false statement, however I am at the CASA office in Tottenham court road and right now i am probably within the range of more than 100 sending and receiving signals. From mobile phones, to wireless networks, to the Geige Continue reading

City portraits by Victor Enrich Wednesday 4th April 2012 at 13:36:00 by en-topia There is something fascinating in visualizing sentences. "Don’t talk about it, picture it". Spanish artist Victor Enrich creates surreal city portraits. Images that resemble virtual landscapes, but with a touch of criticism that derives from capturing extremely intimate urban surroundings and manipulating them as he would do in a virtual environment. There is a little bit of magic in combining everyday architectural pictures with virtual ideas. Continue reading

Visualising Structured Data on Geographic Maps: Evaluating a Hexagonal Map Visualisation Monday 30th January 2012 at 17:06:53 by COVSPC An important aspect of spatial analysis is the choice of appropriate forms of representation. Choropleth maps are an appropriate, widely-used representation for univariate spatial data sets; but how can data distributions be visualised on geographic maps? I.e., how can one visualise data that has spatial, categorical, and quantitative aspects? We developed a map-based histogram based [...] Continue reading

Interactive AR urban planning - Attractive City Generator Thursday 19th January 2012 at 15:20:00 by en-topia Attractive City Generator, is a part of a research program in Zyrich, created by Sofia Georgakopoulou, Edyta Augustynowicz, Stefanie Sixt and Dimitri Demin. " The idea behind it, is to explore urban design methodologies, based on object oriented programming." It is very interesting how this project brings closer the idea of public participation in urban design , since it communicates very successfully basic urban planning principles. The idea of using augmented reality for interactive urban planing models seams very promising for the designers as well. Real time location suitability and many other types of analysis, can be performed in 3d, helping decision making and evaluation. It is certainty a step in making 3d virtual reality something more than iconic modelling. Continue reading
