Mourão Moura - input2012

  1. 1. Geoprocessing, Multi-criteria Analysis, Conflict ofinterest and Simulation of Landscape Intervention:learning topics in Urban Planning, at UFMG – Brazil Prof. Ana Clara M. Moura Federal University of Minas Gerais - Brazil School of Architecture Department of Urban Planning
  2. 2. Recently, a new Architecture and Urbanism night coursewas created at the Architecture School at the Federal University ofMinas Gerais. Since it emphasizes urban planning, it differsfrom the daily course, which has a focus on building project. Thisnew emphasis makes fundamental that students familiarizethemselves with geoprocessing tools:present their planning in a georeferenced manner, usesatellite images, treat images with digital imagingprocessing for territorial and urban planning, exploreresources from Geographic Information Systems and,specially, develop analyses and representation models forurban spaces.
  3. 3. “Urban Planning Workshop: Local Planning Problems”,discussing issues to a district scale (neighborhoodplanning)120 h/aObjectives:- the construction of a conceptual base for studies on landscape,environment, planning,- spatial perception;- training on survey activities;- storage, treatment, and representation of spatial data;- tuition on spatial analyses methodology;- diagnostics, prognostics and propositions of spatial intervention,with the use of geoprocessing;- the study of public policies and legislations regimenting urbansettlements, regarding their contexts.
  4. 4. Vale do Sereno district, which is located in a frontier areabetween two municipalities: the Minas Gerais state capitalmunicipality, Belo Horizonte, and the Nova Lima municipality
  5. 5. Reasons for this growth reside in its being the mosteconomically interesting region for selling real estate within theMetropolitan Region (Região Metropolitana – RMBH) of BeloHorizonte, and since urban regulations (presented at thedevelopment plan of Nova Lima) authorize thisintense growth and transformation on the urbanlandscape.
  6. 6. Economic Interests – urban growth and mineral resources
  7. 7. Environmental interests – landscape value, water resources andvegetation cover
  8. 8. Risks of geology / geotechnical conditions
  9. 9. Methodology for Urban Planning, supported by geoprocessing– Multi-criteria Analyses and Decision Tree“Instead of simply describing elements and facts, models forspatial analyses using GIS can describe scenarios and simulatephenomena, basing on observed tendencies or considerationson pre-established conditions. GIS is used also to select analysesvariables and in the study of their combinations. These areattempts to represent reality in a simpler manner, selecting themost relevant aspects, and seeking information on correlationsand behavior expressed by environmental variables.” (Moura, 2007)

  17. 17. Studies on landscape perception as an assistance tool for imageplanningIn order to students benefit the most, we used field work,interviews with the community, and the making of expressive images,both by hand drawings and digitally altered photographs, capturingthe landscape’s place essence
  18. 18. Conclusions – Urban Zoning ProposalsThe drawing and landscape perception field step was important toslow down the time spent in observing and apprehending landscape,while the students understood their main characteristics and values,they could also mature their reflections on their urban zoningproposals.The project proposals again face them with geotechnologies, sincewe required from them that all processes were undertaken intridimensional representations, in a way they could have controlover their project proposals, develop more effective forms ofcommunication to locals, and simulate their results for predictionstudies.
