Can I enter my own GPS coordinates to create a accurate map of my property...?

I have created a very simple "My Land Plan" map (not accurate, drawn simply by eye). However, I have a bunch of my own GPS coordinates that I would like to include to produce an accurate and usable map. Is there some way to input my coordinates? I don't see an input field. Thank you, Steve

I'm not quite sure how that can be done on the land plan site, but I do have ArcMap 10.2 and can create a map of your propoerty if you can send me a shapefile of the GPS waypoints. I charge $30/hour for this service.
