Applications of GIS in Civil Engineering

  • Transportation
  • Watershed analysis
  • Remote sensing
  • Wastewater, stormwater and Solid Waste Management

Applications of Geographic Information System in Transportation Engineering

Location-Allocation

  • Finding a subset of locations from a set of potential or candidate locations that best serve some existing demand so as minimize some cost
  • Locate sites to best serve allocated demand
  • Application areas are warehouse location, fast food locations, fire stations, schools


Location-Allocation Inputs

  • Customer or demand locations
  • Potential site locations and/or existing facilities
  • Street network or Euclidean distance


The best sites

  • The optimal allocation of demand locations to those sites
  • Lots of statistical and summary information about that particular allocation

Synergy between spatial data and analysis

  • Imagine you are a national retailer
  • You need warehouses to supply your outlets
  • You do not wish the warehouses to be more than 1000 km from any outlet

Other Transportation Applications

Planning & locating new roadway corridors

  • Transportation – Emergency Operations
  • Transportation maps are critical
  • Disaster response plans can be developed
  • Outside computer models used for advance warnings
  • Land use maps enhance emergency operations

Watershed Characterization

  • Relate physical characteristics to water quality & quantity
  • Data – land use & land cover, geology, soils, hydrography & topography – related to hydrological properties

Applications

  • Estimate the magnitude of high-flow events, the probability of low-flow events
  • Determine flood zones
  • Identify high-potential erosion areas. For example, BASINS, HEC-RAS, MIKE11 models integrated with GIS


Slope Stability Analysis

  • Derive physical characteristics, area, perimeter, flow path length, maximum width, average closing angle, watershed topology, soil * data
  • Derive watershed characteristics, watershed boundaries, drainage network, slope & aspect maps

Remote Sensing

  • Image backdrop
  • Source of information on: land use/land cover, vegetation type, distribution, condition, surface waters, river networks
  • Geomorphology
  • Monitor change
