What signifies the highest spot of elevation on a chart?

The highest spot of elevation on a chart is indicated by the largest dot next to the largest numbers. This is because topographical charts typically use symbols to represent various geographic features, including elevation points. The size of the dot often correlates to the importance or prominence of the location, with larger dots typically indicating higher or more significant elevations.

Additionally, the numbers associated with these dots represent the actual elevation in feet or meters, so when the largest dot is paired with the largest numbers, it clearly signifies the highest elevation point on that chart. This understanding of symbol and numerical representation is crucial for effectively interpreting topographic maps or charts in aviation and related fields.
