Go ahead and enter at the very least longitude and latitude data for your site you have an interest in.

And when it will get seriously big, it can be most cost efficient to utilize satellite imagery and remote sensing technology.
Measuring a series of positions in this manner is referred to as "operating a traverse." A traverse that starts and finishes at unique areas is known as an open traverse.
The satellites broadcast indicators employed by GPS receivers on the bottom to measure positions. The satellites are arrayed these that at the least 4 are "in see" all over the place on or near the Earth's floor all the time, with ordinarily around eight and probably twelve "in view" at any offered time.
