Subject: Gis and Urban Design



Urban Design is an area of knowledge started to appear in practice recently, as a sub of the City planning field. Urban Design concerns with areas larger than a building, but less than a city. it become the concentration when we work in neighborhoods, city centers and streets of important, e.g. Water fronts and city squares.

Designing large spaces require working with a lot of data and information, these data are situated in different places and levels, and inherited from different sources, and its difficult to collect all of them in one place and at the same time, and then come the importance of the GIS, where all these information are merged together.

we observe city conditions by, collecting data, reports, taking pictures and videos, detect problems and recording patterns, like patterns of movements and traffic systems. then we assign these data to our map, we code them; it mean we give them location, and even time, in the case of the temporal data. the second stage come when we start to analyse these data, to extract information usable to our design,  we find places   with problems, streets with traffic jams, areas need connectivity, neighborhoods need to be regenerated etc, all these investigations are made using GIS analysis abilities, we use the spatial and numeric data to find relationships and points of interests, and we visualize their existence and measure their density, diversity of distribution and even the happening over different times, and then accordingly we can predict, and interact efficiently according to our design requirements.

Parametric Design allow us to do our analysis in a totally different way than ever, we can use the power of computing in finding all what were mentioned above, we can use shortest paths, we can find affected zones by specific affect-ors, for example, noise and hazards, we can also put our homes away from flooding areas using simulation and terrain analysis. all that and even we can link GIS data to our optimization tools to find the best solutions, we can use our environmental and other per-formative design engines to sort out better sustainable solutions.

in the maps above, I started to work with Khartoum map, I started to visualise data, soon I will show some of the processes I experimented in the mapping exercise
