Natural & Man Made
A topographic survey is commissioned to define the natural and man-made objects situated on a parcel of land.  A topographic survey can be combined with a boundary survey to reflect property lines in addition to the physical features.



Elevations
Topographic surveys generally reflect the elevations of the land when measured at a specified interval.  The elevation data can be combined with the location of physical features to determine drainage patterns and spatial relationships for objects located on the land being surveyed.
