12 Nov Topographic Land Survey
The topographic land surveying service can be used by private owners, the construction industry, and the environmental-awareness sector. The objective of this type of survey is to create topographic plans of elevations of both natural characteristics and manmade structures. These may include hills, streams, rivers, trees, storm drains, structures, utilities, buildings and other improvements on the natural state of the land. A topographic survey shows the location, size, and height of these types of improvements as well as incremental changes in elevation. Topographical surveys are sometimes called level studies, and can be carried out before the land changes hands, or when the landowner is prepared to improve it.
Topographical surveying of a field is more focused on the horizontal elevation measurements. Most measurements are performed with either a GPS unit as topography, or an electronic instrument, EDM. The topographic maps are presented as contour lines on a map of the terrain. Today, sophisticated computer programs allow digital versions of these maps and interactive elevation view of the earth. The data may be used in CAD programs (like Terramodel, Microstation, AutoCad), and can be manipulated by engineers or architects to show how topography will change through the planned improvements.
Having a survey conducted prior to land acquisition can ensure that the characteristics of the land will be suitable for its intended use.
A survey provides an accurate view of how land use has changed, allowing better planning for future use.
