Color of ink to plot the latitude and longitude of corner 1 on plan

Focusing on making critical reference points stand out is essential in plan plotting. The latitude and longitude of a corner are key georeferencing details that readers must locate quickly, especially when staking out or verifying positions. Red ink is traditionally used to emphasize control points and important annotations, giving high contrast against the usual black plan lines and notes. This makes corner 1’s coordinates immediately identifiable on the sheet. Other colors carry different usual meanings—blue often marks water or proposed features, black is the standard for main lines and text, and green denotes vegetation—so they don’t highlight the coordinate point as effectively.
