Remote Sensing of Urban Environments


Abstract Remotely sensed observations of built environments are controlled by the physical properties of the materials and the structural form of the objects used to construct the environment. When using remote sensing to map and monitor built environments, it is important to understand how different sensors respond to the objects and materials. We give a brief overview of some fundamental characteristics of built environments as imaged by optical, microwave, thermal, and night-light sensors. The focus is on the relationship between physical characteristics and sensor response in the context of uniqueness and fundamental questions of inference based on remote measurements.
