Isovists and Occlusion Maps
    Peter Edward Atwood

    Dunham’s project and its representation of the walkability in Dubai brings to my mind a paper written by Mike Christenson published in 2010. In his paper, Registering visual permeability in architecture: isovists and occlusion maps in AutoLISP, Christenson further investigates the use of isovist to quantify perception. The graphics associated with points along a path inside some environment, which Dunham has shown here is, I feel similar to the isovist illustrations provided by Christenson, however I feel the paper defamiliarizes Dunham’s work because it suggest that these isovist can be deployed in an environment and that this deployment has its own set of concerns worth considering. Where Dunham’s work has used the illustration to represent an existing set of conditions, Christenson appears to be suggesting that a systemized illustration and its application or deployment could manifest unknown potentials.

    2.01 Urban Walk-ability Premeditated through Population Densities from Transit Stations: Matthew Dunham
    Matthew Dunham

    Original Dubai Proposed Masterplan




    These are the calculated [computational] mappings I have done based on the chosen urban location [Dubai] and the assessment of the community(s) using AutoCAD. The chained cyan smaller circles are 1/2 mile in diameter representing the walk-ability, for that region of the world, around the metro stations. The hatched yellow circles represent the population of 80,000-100,000 people clustering the most population density near downtown (noted by the large circle). The closest idea of a calculation is the variable of walk-ability, basted on temperature (day vs. night) walk ability can increase.
