The point is now ready to plot. Instead of just plotting a single dot, this time try marking the spot with an X.
现在可以画点了，但是这一次不是简单地画一个点，而是要用 X 来标记。
Results GPS could record and save the route which the investigators walked in the spot, the longitude and latitude of each dot position could be collected consciously at the same time.
结果手持GPS设备可以对现场行走的路线进行准确定位(自动保存为“航迹”)，同时可以手动采集每个航点的经纬度。
