b) with more
white pixels. This could be confirmed in the southwestern Houston, such as
Gulfton, Sharpstown, and Bellaire, and southeastern Houston between Deer Park
and Pasadena. The incorrect predictions were always also found in the indus-
trial/commercial area in the Southern and Northeastern Houston, such as Missouri
City and Jersey village. It was easy to understand since the chosen socioeconomic
data, especially the population density and house density, were better to represent
the residential area instead of industrial/commercial area.
Further validation of models between the simulated one and predicted one
was analyzed through the confusion matrix (Table

). This table showed the
comparison results between the simulated result and empirical maps as the value of
