GPS Plotting Protractor enables accurate map plotting

摘要

While the Global Positioning System (GPS) enables an individual to obtain position information to an accuracy of ten metres, it has not been easy for this information to be transferred to plot a position on a map to the same level of accuracy.Andrew Dahl, a partner in Military Template Technology, claims to have invented the first GPS Plotting Protractor. He says that its release makes it possible to quickly and easily measure and plot position data on g geographic map to an accuracy of ten metres.
