There are multiple types of land surveys. Many clients already have a simple land survey or a Title Survey from when they purchased a property. A topographic/tree survey is a detailed mapping of the existing conditions of a property. A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations.
