False color Landsat imagery can aid in urban detection with certain limitations. A population threshold of 10,000 appears to be a reliable level for detection in Ohio. At this level, 89% of Ohio urban places were detected. Below this threshold, chances are one in two of detecting an urban place. Accuracy of detection varied with urban size and seasonality of imagery. In general, as city size increased accuracy likewise increased. Area of the city and Central Business District were important factors in detection. Late winter scenes were best for detection while late summer scenes were least favorable.
