Nine flight lines of data (shown as lines 1 through 9 on the left column) were collected from our model LC130. Each
line shows 20 measurements of elevation for the land surface below the ice sheet. Think of the plane flying 9 separate survey
lines across the ice sheet and recording elevation measurements of the land surface below as it flies. Elevations are recorded in
meters.
Each flight line 1 through 9 contains numerous data points but
the plane was set to report at intervals, posting only a total of 20
points per line. The program was set up to collect each reading as a
distance from the plane to the land surface, it then inverted
900 (reversed) the reading so the that the number at each point in the
800 chart above is actually showing land surface elevation. The larger
700 the number reported in the box, the higher the elevation. Line 2 is
Line 2 600 drawn for you to demonstrate that data point #12, shown as 860
500 meters of elevation on the chart, is the highest point on the graph.
