Metes and Bounds 4.6.0 was released a few days ago. Metes and Bounds is a long-time application that allows you to work with geographic data, including creating deed plot maps. It also calculates the area of those plots (including square feet, acreage, and hectares), and can support measurement in rods, chains, meters, yards, inches, fathoms, hands, spans, or furlongs.
It can be handy if you are doing a lot of research into plots and working with surveys, and have measurements or other data available. It does support GPS waypoints. It’s $29.95 for the basic version, $69.95 for the pro version. For more information, see the website.
