Understanding Urban Environments from Satellite Imagery: Approaches, Data Extraction Methods and Applications
Abstract:
Studies
on urban environments/ on THE urban environment require comprehensive
understanding of the complex phenomena which shape and interact in
urban contexts. One of the most important aspects in understanding
urban environments is the use of the spatial approach, which can be
carried out with the help of remotely sensed imagery. Satellite
imagery can give a synoptic overview of an area, so that homogeneous
analytical units can be developed as a basis for stratified sampling.
Time series analysis using multitemporal images enables planners to
monitor and to predict land-use change as well as urban area
development. This presentation describes several approaches which can
be used to study urban environments, followed by an overview of
information extraction methods based on currently available satellite
data. Several applications which integrate remote sensing and
geographical information systems (GIS), related to land-use
classification, settlement pattern analysis, land-use change and
fragmentation, urban heat islands, vector-borne infectious diseases,
urban green spaces and a prediction model for urban area development
are briefly explained, including their advantages and limitations.
This presentation also highlights some research needs from the
geoinformation perspective.
