Appendix

Spatial measurement module includes “point measurement,” “distance measurement,” and “area measurement.”
Click “point measurement” button, and then click on the geosphere interested target. The latitude and longitude coordinates can be obtained (Figure 2-22).

Figure 2‑22. Point measurement output

Click the “distance measurement” button, and draw lines on the geosphere to get the distance. The result is shown in Figure 2-23.

Click “area measurement” button, choose points on the geosphere in turn to draw a polygon, double-left-click to close the polygon. The system will measure the area of the region the polygon contains, and the result is shown in Figure 2-24.
