Remote Sensing of Roads and Highways in Colorado

Large-Area Road-Surface Quality and Land-Cover Classification Using Very-High Spatial Resolution Aerial and Satellite Data

The project aims to combine the image analysis and classification expertise of the University of Colorado with the large data observational and analysis capabilities of DigitalGlobe Inc. to develop two products:

 (a) large-area very-high spatial resolution classification map of widely applicable land-cover classes and

 (b) satellite- based estimates of paved surface quality using the International Roughness Index (IRI).

This will provide our partner transportation organizations the ability to leverage this information for planning and monitoring activities. The relationship of surface quality metrics to remote sensing data will first be established through the correlation of in-situ IRI measurements with aerial data. This relationship will then be extended to a large-area using very-high resolution satellite data. This data will also form the foundation of the classification maps, providing the eight-band multispectral and panchromatic resolution necessary to develop urban scale (on the order of a meter) resolution information.


  1. Create the Advisory Board (AB) and conduct Kick-off team meeting and other subsequent meetings with advisory board
  2. Develop satellite/aerial surface quality metrics and correlate with in-situ measurements
  3. Carry out satellite image model portability development
  4. Creation and maintenance of a project web site for the duration of the project
  5. Quarterly reports to DOT and local MPOs
  6. Develop foundation land-cover classification
  7. Semi-annual collaboration meetings
  8. Assess the ability of the classification scheme to identify and locate roads
  9. Optimization of the classification scheme for high-performance computing
  10. Perform the paved/unpaved surface condition assessments
