Command DIST will not run unless the satellite image is navigated or a MAP command is run.
Each cursor location marked on the graphics frame is indicated by a period (default) or a symbol chosen with keyword SYM. A symbol is plotted on the graphics frame at the new cursor location each time you press the middle mouse button.
DIST runs interactively when specified with no parameters, or with the ROT, STE, E, I or T parameter.
Position the cursor at the point on a navigated frame that is the starting point of the calculation. Then,
The program replies:
Move the cursor to the starting point from which you want to measure one or more other points, then press the middle mouse button or Alt G. Next move the cursor to the first point you want to measure and press the middle mouse button or Alt G. Move the cursor to all subsequent points you want to measure, pressing the middle mouse button or Alt G at each point. Press the middle and right mouse buttons or Alt Q after measuring all the points.
Each time you measure a point, the SYM keyword symbol and the distance to the starting point are plotted on the graphics frame. Also, the latitude and longitude of the point and its angle and distance to the starting and previous points are listed on the text frame.
DIST CIR 45 30 100 SYM=*
This entry draws a circle of asterisks on the graphics frame 100 km away from the original cursor location beginning at angle 45. The circle contains 12 asterisks since the increment is 30°.
DIST ROT 90 15 200 UNIT=NMI SYM=* SIZE=20 COLOR=4
This entry draws an arc or circle of asterisks on the graphics frame 200 nautical miles away from the original cursor location, beginning at an angle of 90°. The asterisks are 20 pixels high in graphics color level 4.
