REMOTE SENSING
SYSTEMS FOR
URBAN AREAS
Part II (Ch. 2 - Ch. 6) reviews the latest developments in remote sensing systems that are particularly relevant to urban studies. It
covers a group of imaging systems that has been in use for quite a long period and another group of relatively new systems with
advanced capabilities. The first group focuses on the Landsat imaging systems that have acquired a scientifically valuable image archive
unmatched in quality, details, coverage, and length, which has been the primary source of data for urban studies at the regional, national
and global scales. Chapter 2 discusses the utilities of archival Landsat imagery for the observations and measurement of urban spatial
growth and landscape changes. The other group includes several advanced systems acquiring data with very-high resolutions over the
optical or microwave portion of the electromagnetic spectrum. Chapter 3 examines some major challenges, limitations, and possible
solutions when using the data from very-high-resolution optical satellite remote sensing systems for monitoring human settlements.
Chapter 4 discusses the development of an automated system for mapping urban surface materials from hyperspectral remote sensor
data. Chapter 5 discusses some new possibilities and challenges when using very-high-resolution space-borne radar data for urban
feature extraction. Finally, Chapter 6 details a comprehensive approach for automated creation of three-dimensional building models
from airborne lidar point cloud data fused with aerial imagery.
