Where should team members look to resolve disagreements about map orientations such as true north and magnetic north?

The correct answer is the Declination Diagram, which illustrates the relationship between true north, magnetic north, and grid north. This diagram typically appears on topographic maps and provides crucial information on how to convert between these orientations, which is essential for accurate navigation and understanding of the map's orientation.

When team members encounter disagreements about map orientations, the Declination Diagram serves as a reliable reference, allowing them to clarify any misunderstandings regarding these directional indicators. By consulting this diagram, they can ensure that they are all aligned in their understanding of where true north and magnetic north lie in relation to the map being used.

The other options may contribute to map reading and orientation but do not directly address the resolution of disagreements about the specific orientations of north. For instance, the Compass Overview provides information about how to use a compass but does not define the relationship between true and magnetic north. The Map Legend explains symbols used on the map, while the Grid Coordinate System assists in pinpointing locations but does not clarify the different north indicators. Thus, the Declination Diagram is uniquely suited for resolving such disagreements.
