Iirs Remote sensing application in Urban Planning

  1. 1. REMOTE SENSING APPLICATIONS IN URBAN PLANNINGINTRODUCTION The modern technology of Remote Sensing which includes both aerial aswell as satellite based systems, allow us to collect lot of physical data easily,with speed and on repetitive basis, and together with GIS helps us toanalyze the data spatially, offering possibilities of generating various options(including modelling), thereby optimizing the whole planning process. Theseinformation systems also offer interpretation of physical (spatial) data withother socio-economic data, and thereby providing an important linkage inthe total planning process and making it more effective and meaningful.Generally, these Remote Sensing data products have following applicationsü in mappingü in interpretation / analysisü as map substitutes
  2. 2. REQUIREMENT OF URBAN AND REGIONAL PLANNERS Apart from topographical mapping, the planners also look forward to the Remote Sensing (data products) technology to provide them information on existing land use and their periodic updating and monitoring. In addition, with appropriate technique and methodology the same data products can be used to:Ø Study urban growth/sprawl and trend of growth.Ø Updating and monitoring using repetitive coverage.Ø Study of urban morphology, population estimation and other physical aspects of urban environment.Ø Space use surveys in city centers.Ø Slum detection, monitoring and updating.Ø Study of transportation system and important aspects both in static and dynamic mode.Ø Site suitability and catchment area analysis.Ø Study of open/vacant space.Ø -------------------

  26. 26. Conclusion•More and more sensors and sensor types are available•Number of available space images is growing permanently•More and more companies are entering the space market•Tendency to real private projects•Competition will reduce the cost•0.6m pixel size from space available – allowance up to 0.5m pixel sizeis useful for mapping up to map scale 1 : 5000 – 1 : 10 000•Stronger overlap of space and airborne applications
