I've had a few requests over the years to do someone else's maps. While I wasn't in charge of the measurement, I make sure my name goes on the maps I make. I honestly love doing the paperwork end of the process. So, should anyone download the certificate map, my name is on the document as the one who created the maps.
If I am in charge of the measurement, and I did all of the brain-work, I want to be listed as the measurer. But since I measure as a team of two most times, I add my second rider on the map. Usually it is just a name and credentials if they have any, but I may start putting contact information on it as well.
I did my years of measuring as a second rider and received no recognition. It's just a part of training and doing the time. My name eventually got top billing when I started doing the planning, coordinating, measuring and paperwork. I'll gladly ride second for anyone, and not take the credit. It's still money in my pocket.
