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.
