EYE IN THE SKY: SATELLITE IMAGERY AIDS FLORIDA DOT

This article discusses the use of satellite imagery on the Jacksonville Outer Beltway Northern Loop project. The project was 30 miles long and the study area was 91,000 acres in a relatively undeveloped area of Duval County. Satellite imagery not only provided a visual image, it also provided a way to interpret the image to produce data in a digital format. The identification and location of environmentally sensitive areas was accomplished within 45 days, saving approximately 3 1/2 months time that would have been required if traditional methods had been utilized.
