| Summary: | There is a growing need for municipal councils to map and to monitor the
extent and condition of urban green spaces, as one measure of the overall
sustainability of a city. In this study, we identify the information about urban
green spaces that can be obtained from satellite imagery. This research
which is based in the city of Kuala Lumpur tests the ability of IKONOS
higher resolution satellite imagery in identifying the different types and the
different functions provided by green spaces using both automated methods
and manual methods of visual interpretation. Both these methods were found
to produce a map of green space for the entire city area that was 70%
accurate when validated against ground surveys. In cases where higher
resolution satellite imagery exists, we show how it can produce a variety of
enhanced information which may enable city planners to monitor green
space more regularly and to evaluate consistently which areas of green
space within the city ought to be protected in order to maintain its benefits
for the city population |
