Points of Interest

1.	What is a POI?
	'POI' stands for 'Point of Interest' or 'Place of Interest'. It is a location on a map. Specifically, it is a named geographical coordinate that is an intersection between a latitude and longitude measure. POIs are used on GPS-enabled devices to create a relevant destination point on a map for an end-user.

2.	What is GPS?
	GPS is an acronym for 'Global Positioning System'. It is the underlying technology utilizing orbital satellites that allows a GPS-enabled receiving device to determine location, speed and direction.

3.	What are coordinates? What is latitude and longitude?
	Coordinates refer to a specific point on the earth – made up of an intersection between a latitude number and longitude number (typically measured in degrees but can also be represented numerically). Latitude provides the location of a place on earth north or south of the equator and runs 'horizontally' on the globe. Longitude provides the location of a place on earth east or west of a north-south line called the Prime Meridian. Combining latitude and longitude allow us to pinpoint a specific location on the earth.

4.	Don't GPS devices already come with POI data loaded on the unit?
	Yes this is true. However, most estimates and feedback from users state that up to 50% of the POI information is incorrect and out-of-date. This has resulted in a lot of frustration for users who expect to find something in a certain location – only to arrive and find that it doesn't exist. Having the ability to download Exxon, Mobil and Esso locations is purely a benefit that ExxonMobil wishes to provide to customers for added convenience.
