A topographic survey may be defined as one that determines ground relief and location of natural and man-made features thereon. Performing a topographic survey requires taking shots of the natural terrain at:
• grade breaks
• along channels
• along corners and alignments of fixed works
• at brush boundaries
• other details of the natural terrain
• other man made objects
The location of trees might also involve shots at the drip line and measurements at the top of the crown.
Measurements for utility structures (poles or towers) might also involve shots at various points on the wire.
A construction survey may be defined as one that locates points prior to, during, or after construction of a fixed work on a site. That fixed work may be a road, structure, or may involve excavation or fill of materials. Also called stake-out.
Often, a survey to check the final position of a structure is called an “as-built” survey.
