Remote
sensing is an essential tool of land change science because it facilitates
observations across larger extents of Earth’s surface than is possible by
ground based observations. This is accomplished by use of cameras,
multispectral scanners, RADAR and LiDAR sensors mounted on air and space borne
platforms, yielding aerial photographs, satellite imagery, RADAR and LiDAR
datasets. (http://ecotope.org/people/ellis/papers/ellis_eoe_lulcc_2007.pdf)
Remote sensing
• Helps connect local resources
with global perspective
• Can address immediate needs
for information or graphics
• Shows change over time
• Provides unique views of natural
disasters
• Helps interpreters support
management decisions
• Helps spark interest among
visitors
• Connects today’s exploration
with themes of historical sites
• Are great sources of information
Remotely sensed imagery is an
effective data source for urban environment analysis that is inherently suited
to provide information on urban land cover characteristics and their changes over
time at various spatial and temporal scales [2–6]. In the past decades, remote
sensing has been widely used in various applications, such as urban structure
extraction, urbanization monitoring, change detection, and so on [5,7–13]. With
the development and innovations in data, technologies, and theories in the
wider arena of earth observation, urban remote sensing has rapidly gained
popularity among a wide variety of communities from many aspects such as Land
Use/Land Cover (LULC mapping, Urban Heat Islands (UHIs) analysis, impervious
surface area estimation and urban ecological security assessment (Du, P. et al,
p.6)
