This area is currently for the use of NASA researchers, and any data presented here should be considered a preliminary data product. The passive data is plotted as measured without equalizing the different passes. Partly cloudy conditions created large variations in sun illumination between successive passes over the map area. The developed area, beach, and breaking surf are easily discernible.
Some maps show details around the beach, inlet, and town.
The ATM2 laser altimeter is installed in the twin-otter . The scanner on the altimeter traces out an oval pattern on the ground below the airplane. In preparation for the mapping mission on the West Coast, a test flight was made over Calvert Cliffs , Maryland. The plots are in two parts, one for the first three weeks and another for the second three weeks.
