Topographic Land Surveys: A Guide

The land survey that many individuals are acquainted with is that which involves setting boundaries of a section of real estate, but this is just one of the very many types of land survey. A topographic land survey works extremely well for homeowners or those within the construction industry or environmental industry. The aim of a topographic land study will be to note the natural and human-made physical feature inside a land. These can sometimes include slopes, ravines, avenues, woods, walls, structures, as well as other developments within the natural condition of the property. A survey like this reveals the location, measurement, and height of these types of features, as well as progressive changes in level. Topographic surveys are sometimes called contour studies and may be conducted before the land changes ownership during sales, or because the landowner is getting ready to start some major develops on the ground.

Unlike land surveys involving the boundaries, topographical land surveys concentrate on altitude and elevation than on horizontal dimensions. In this survey, most measurements are carried out using a surveying quality GPS unit or an electronic EDM device. The outcomes of the study are not designated with stakes or some other landmarks as with almost other types of land survey. Instead, they are introduced as contour lines on the maps of an area to show altitude. Today, sophisticated computer packages enable electronic designs of these maps, as well as interactive elevation view of the land. The data may be used in AutoCAD programs, where it could be controlled by designers or engineers to show the way the topography will transform through the planned changes.

There are many uses of a topographical land survey. In some cases, they are a requirement by the government. Many engineers and architects use these surveys to come up with buildings and further modifications on an existing property because the current features on a land influence style and decisions on where to build a structure on land. All construction jobs begin with this kind of topographic property study, which explains the start off point of the land.

Topographic surveys may also be used when deciding the proper policy for drainage ditches, grading, or other features, utilizing the natural topology as the basis of such changes. The study will also report any gradients on the land, which is significant if you are considering building on the land, as an 8-degree angle adequate for construction while any gradient that is above eight which have serious financial implications with regards to physical requirements for construction. Having a topographic survey done ahead of buying the land could make sure that the land has typical features.

Aside from undeveloped land or land with structures, this kind of land study can also be beneficial to a place which had been used and now needs to undergo redevelopment. For instance, topographic surveys might be done on land which had a structure, and it has been demolished, or of a quarry, landfill, or other places with changing topographic data. In these cases, this survey gives critical information regarding how land topology has changed over time, and this allows for appropriate planning.
