Difference between PID and designation

Followers 0

Recommended Posts

The PID is the permanent identifier. It is a unique ID code for a station. It is the easiest way to look up a specific mark. The designation is what is on the mark or a description for the object. For benchmark discs, it is usually a letter and then a number. But for other things it can be different. For example, water towers will have a PID such as KB1034, but the designation would be something like Carbondale Municipal Water Tower East. (BTW, this is a made up example. I have no idea what KB1034 is.)


Hope this helps.
