Summary
Small-area
population estimates are essential for understanding and responding to many
social, political, economic, and environmental problems. Population estimates
are critical in decisions concerning resource allocation, market area
delineation, new facility/transportation development, as well as generating
diagnostic indicators for environmental and socioeconomic assessments.
Despite its significance and the update frequency needed, detailed and
accurate population and socioeconomic information is only available for one
date per decade through the national census. The recent advancements in
remote sensing technology coalesced with existing knowledge in the field of
applied demography can lead to developing an effective method to project
population more accurately in different applications. For example, the launch
of IKONOS in 1999 provided new opportunities to investigate urban physical configurations
at a fine spatial scale from very high resolution (VHR) optical images.
Likewise, the advent of Airborne Light detection and Ranging (LiDAR) sensors
for measuring the vertical information has complemented the information
provided by optical VHR imagery in many urban studies. The overall objective
of this project is to develop detailed (census block level) and accurate
population estimates through integrating the traditional housing unit methods
and remote sensing technologies. |
