A study may be conducted for exploring the compilation of some of the indicators of urban accounts using satellite data/geo spatial data. This may include checking of data availability, suggesting other indicators as per the spatial data availability, alternate data source related to following indicative components:

  • Disaggregation the entire urban area and categorizes larger patches with common characteristics. For example, a classification of urban sub- types could break down the variety of built-up and semi-natural types within the city into contiguous areas with common shared characteristics (e.g., compact high-rise, compact low-rise, open low-rise, sparsely built, paved, semi-natural area, natural area).
  • Identification & Data collection on individual asset types of urban area at as fine a scale as possible (e.g., lines of street trees, playgrounds, allotment gardens, green roofs, drainage and storage systems, etc.) based on available very high resolution (10 m or less) satellite imagery or other spatial data sets
  • Following the disaggregation of urban area, Identification and collection of information on condition characteristics of urban area (e.g., percentage of impervious/pervious surfaces, air quality, water quality, soil contaminant concentrations) as measures of landscape-level characteristics of these subclasses.
  • Quantifying ecosystem service in terms of volume and money value: Identification of urban ecosystem services and checking of availability of data for these ecosystem services, such as air purification, water regulation, carbon sequestration temperature moderation, and recreation, provided by urban ecosystems.
