Final answer:
A six-digit PDG grid coordinate will locate a point within 100 meters. It uses six digits for 100-meter accuracy in MGRS mapping.
Step-by-step explanation:
A six-digit PDG (Precision Distance Grid) grid coordinate will locate a point within 100 meters. A PDG grid is commonly used in map reading and land navigation provided by Military Grid Reference System (MGRS). Each additional digit in a grid coordinate provides a more precise location by decreasing the area it references.
A four-digit grid will reference an area of 1 kilometer by 1 kilometer, while a six-digit grid refines this to a 100-meter by 100-meter area. Therefore, the location specified by a six-digit grid coordinate is accurate to within 100 meters.
The Precision Distance Grid (PDG) system, integral to the Military Grid Reference System (MGRS), employs six-digit grid coordinates to pinpoint locations within a 100-meter accuracy. As each additional digit is added, the precision increases, with a four-digit grid covering a 1 km² area and a six-digit grid narrowing it down to a 100-meter by 100-meter zone. This hierarchical grid system enhances map reading and land navigation accuracy, crucial in various military and civilian applications.
