Within how many meters can a 6-digit grid coordinate locate an object?

• A. 10 meters
• B. 100 meters
• C. 1 meter
• D. 50 meters

Answer: (B)

A 6-digit grid coordinate is designed to provide a specific location on a map with a precision of 100 meters. Each digit in the coordinate represents a specific division of the grid system. The first two digits indicate the distance east of the origin (the easting), and the next two digits show the distance north (the northing), both within a 1,000-meter square grid.

The last two digits further refine the location within that grid square, allowing for more precise positioning. However, the 6-digit format does not extend the precision beyond centimeter-level detail; therefore, it effectively locates an object within a larger area of 100 meters.

This level of precision is useful for many operational contexts, but if finer detail is required, a 8-digit grid coordinate would be necessary, which would localize an object to within 10 meters. Hence, the correct understanding of a 6-digit grid coordinate centers around its capability to provide locations with a precision of 100 meters.
