Objectives

  1. Coordinate efforts towards the establishment of a global data infrastructure for urban data and products
    Develop the architecture, data management policy, data portals, software, and tools needed to improve global coverage and data accuracy of urban observing systems through integrating satellite data observed from multiple platforms/sensors and different resolutions, with in-situ data;
  2. Engage institutions, stakeholders and users in the development of a global initiative for urban observation
    Develop a global urban observing network under the umbrella of GEOSS, establishing regional alliances and encouraging the establishment of a Program Office;
  3. Define requirements for global urban observation and assessment in terms of data products and expectations for data validation, archiving, update and sharing.

Activities

  • Conduct global urban analyses, including time-series for assessing mega-cities development (e.g. urban sprawl) and a world-wide inventory of human settlements based on satellite data (5 groups in GEO)
    Conduct urban analyses linking Earth observation products with socio-economics and environmental quality data, to improve knowledge of urban ecosystems
  • Create a global urban morphological database for urban monitoring / assessment and climate modeling to better understand the impacts of global warming and climate change on urban areas.
  • Conduct surveys to assess the magnitude and dynamics of the urban “heat island” effect, particularly for cities in developing countries, and identify environmental impacts on “Megacities”

Related tasks: Climate Information; Health i.e., Air-borne Diseases, Air Quality and Aeroallergens; Investigation of the relationship between the thermal urban environment and heat-related morbidity and mortality,.. 
Assess vulnerability to extreme climate events and disasters. Makes cities more resilient.

Leads

Global Urban Supersites Initiative

  1. To provide globally distributed data (EO and derived products) to establish an urban data repository and to develop standards
  2. To estimate urban extent and associated changes
  3. To assess risks associated with natural hazards, air and water qualities, and health hazards
  4. To derive urban biophysical parameters for characterizing urban land surface-atmosphere interactions
  5. To enhance analysis techniques and methods those illustrate the causes and effects of urbanization at local, regional, and global scales
