In grid coordinate notation, which sequence correctly maps digit length to distance?

• A. 6-digit equals 100 meters, 8-digit equals 10 meters, 10-digit equals 1 meter
• B. 6-digit equals 1 meter, 8-digit equals 10 meters, 10-digit equals 100 meters
• C. 6-digit equals 1000 meters, 8-digit equals 100 meters, 10-digit equals 10 meters
• D. 6-digit equals 100 meters, 8-digit equals 10 meters, 10-digit equals 1 meter

Answer: (D)

In grid coordinate notation, the number of digits tells you how precise the location is. Each additional pair of digits narrows the area by a factor of ten. So six digits pin you to a 100-meter square, eight digits to a 10-meter square, and ten digits to a 1-meter square. This means the six-digit reference places you within a 100 m by 100 m area, adding two more digits concentrates that to a 10 m by 10 m area, and two more digits further concentrates to a 1 m by 1 m area. It’s why the progression 6-digit → 100 meters, 8-digit → 10 meters, 10-digit → 1 meter makes sense: each step adds precision by an order of magnitude, letting you move from a broad area to a specific point as needed.
