INTRODUCTION:
The U.S. Geological Survey contracted with Dighem, then a division of CGG Canada, Ltd. of Mississauga, Ontario, Canada, to fly a helicopter electromagnetic survey over parts of Everglades National Park and surrounding areas in south Florida. Survey covered 398 square miles (1031 sq. km) with total flight-lines totaling 1718 miles (2765 km). The data were collected towards the end of the wet season from 9 December through 14 December 1994. This report contains the contractor's original report and flight-line data set. In addition, a version of the data set that was corrected by the U.S. Geological Survey to remove errors associated with calibration and operational procedures is also included. A brief description of the procedures used to correct the data set is given. |
