GPS Evolution to Digital Mapping Capabilities
Whether you’re using your Garmin to navigate roads and highways, off road, on the trail, or even blazing and bushwhacking, tracking your location on your GPS screen is a priority. Garmin handheld GPS maps are the digital representation of the lay of the land which can be very basic or highly specialized. Different Garmin maps can include icons for Points of Interest (POIs), trails, detailed descriptions, contours (to know the exact vertical constitution of a hill or mountain), and symbols for man-made objects which can help you avoid falling into something like an abandoned mine shaft.
Although it can be enriching to get lost once in a while by seeing your position from the perspective of the old adage “you have to lose yourself to find yourself" or by the other and less known definition of lost; “seeking alternative destinations"; if you own a GPS you probably want to know exactly where you are. The older GPS models and the inexpensive models give you only the coordinates of latitude and longitude and then you’d have to study and transfer those coordinates to an old fashioned paper map. Without that map, those numbers were basically meaningless to you in terms of orienteering.
