However, I will be concentrating on Canada for now. Seeing as the old and new system are capable of creating Cadastres lets first look at what a Cadastre is. Every country in the world uses some form of cadastre mapping in order to identify parcels of land, and borders. There are three parts to a parcel of land; the owner or interested party of the land, the surveyor who marks the property with monuments, and the plans and maps of the property. (Ballantyne, Northern Lights: Defining Boundaries with Coordinates, 2008) It is a way for a country to control ownership of real estate whether that is public or private.

GPS, medical monitors and cell phones all contribute to the important skills diminishing. First, with GPS devices we no longer need to learn how to navigate or read a map.
