peri-urban landscape undergoing change. Of particular significance is the rela-
tionship between the spectral signatures and the ternary plot. It is of course the
spectral signatures, which define the classes.
Quantifying and mapping the V-I-S urban/peri-urban environmental com-
plex serves as a foundation for many physical models in science and engi-
neering, such as the two exhibited herein. Many others such as evaporation
rates, water uptake, air quality, and soil condition find a connection to and
from the V-I-S foundation and its changing patterns. Human factors such as
housing density, population, and income levels may also be related. Much
research lies ahead. Improving sensor resolution, interfaced sensor data
(VISNIR, SWIR, thermal, radar, lidar, etc.), and more robust information
extraction techniques provide continued opportunities for remote sensing
applications of the V-I-S model.
