Tennessee Specific Surveying (TS) Practice Exam

Soundings on the survey are shown in which color?

Red Black Blue Green

Correct Answer:

Black

Explanation:

Soundings, the measured depths or elevations shown on a survey plan, are traditionally drawn in black. Black ink provides the clearest contrast and remains legible when copies or scans are produced in grayscale, which is common in field reports andoffice workflows. Using black also helps the numerical elevation data stand out amid other color-coded features, reducing confusion with things like proposed features, utilities, or water features that might be colored differently. While some contexts may use blue for hydrographic data or other colors for specific categories, the established practice for soundings on standard survey drawings is black.
