What is a Topographic Survey?

Topographic surveys are trigonometrically calculated, map-based representations of the earth. The calculations are done by a surveyor to give an approximation of the earth's surface. These surveys provide basic information for land planning, development, and infrastructure construction.

The surveyor calculates the elevations in relation to a selected datum or datums (mean sea level) and their position on the earth's surface. The topographic survey is a three-dimensional graphical representation of the features and elevations of a parcel of land.

I own 34 acres in West Virginia with a very steep hillside.
I am looking for a pretty accurate topography map that I can use to build logging (and later ATV use) from the bottom to the top.
What type of survey would be best because the property is 99% forested?
I also need all 4 corners and then staked every 200' or so on the line between corners.
Thanks
