19. SURFACE AREA CALCULATION
You can calculate the area of land enclosed by three or more known points on a
line by inputting the coordinates of the points.
• Number of specified coordinate points: 3 or more, 30 or less
• Surface area is calculated by observing the points on a line enclosing an area
in order or reading in the previously registered coordinates in order.
%
• If two or less points are used to measure an area, an error will occur.
• Be sure to observe (or recall) points on an enclosed area in a clockwise or
counterclockwise direction. For example, the area specified by entering (or
recalling) point numbers 1, 2, 3, 4, 5 or 5, 4, 3, 2, 1 implies the same shape.
However, if points are not entered in numerical order, the surface area will not
be calculated correctly.
