Final answer:
In engineering, centerline stakes are placed at less than 100-foot intervals in scenarios requiring greater precision for navigation or layout, such as in complex topographies or marine missions with homogenous bottoms.
Step-by-step explanation:
Centerline stakes should be placed at less than 100-foot intervals in conditions when more detailed guidance for navigation or construction layout is necessary. This may occur in areas where the topography is complex or changes rapidly, in environments with irregular and homogenous bottoms that lack natural points of reference, like the seabed areas with dispersed colonies of Caulerpa, or in situations that require precise measurements for safe navigation and work progression, such as setting up guide lines for divers in marine missions.
In zone missions with mobile guide lines, these stakes, or lines, are adjusted as the inspection moves from deep to shallow areas, ensuring accurate and safe construction or inspection pathways.
