Ground control factors are 'those big square points' -? Right - but they're a lot more than that also. In this post, we'll cover what ground control points are, as well as why they are essential in an aerial mapping job.

They're virtually always black as well as white due to the fact that it's less complicated to recognize high comparison patterns. The points may be determined with conventional surveying approaches, or have actually used Li, DAR, or an existing map - also Google Planet. There are lots of means to make your own ground control factors and also theoretically, GCPs can be constructed out of anything.

We recommend making use of at the very least five ground control points. If you were checking a best square, it would certainly be very easy to respond to that inquiry: one ground control factor at each edge, and also one in the.
