Topographic Land Surveys: A Guide

The land survey that almost all individuals are aware of, a survey marking the boundaries of a little piece land is just one of a variety of types of land surveys. There is also the topographical survey which homeowners, those in construction sector or environmental sector can use. The purpose of the topographic land survey is to identify all the natural and artificial features of the land. These can sometimes include slopes, ravines, avenues, woods, walls, structures, as well as other developments within the natural condition of the property. A study like this demonstrates the positioning, measurement, and height of those types of events, together with progressive changes in altitude. 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 border or residential area surveys, a topographic land survey focuses more on heights than on horizontal measurements. In this survey, most measurements are carried out using a surveying quality GPS unit or an electronic EDM device. The results of this survey are not marked with stakes and other landmarks like in other types of review. Alternatively, this survey makes use of contour lines on maps of a location. Today, advanced computer packages permit electronic presentation of those plans. This data may be employed in AutoCAD plans, where it may be manipulated by engineers or architects to exhibit how topography may adjust through the proposed developments.

Topographic land surveys have many uses. In some cases, they may be required 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 tasks start with this type of topographic land survey, which describes the starting place of the land before any changes begin.

Topographic studies may also be utilized when identifying the suitable policy and strategies for drainage ditches, grading, or other features, using the organic landscape while the schedule for such developments. From the survey, you will determine any slopes within the land which can influence any construction plans and usually 8-degree slope is suitable for construction while a slope that exceeds that will have high requires during construction thus being expensive. Having a topographic survey done ahead of buying the land could make sure that the land has typical features.
The Key Elements of Great Buildings

Apart from its importance in undeveloped land and areas with buildings, a topographic survey is essential for a land that had been used, but now the owner wants to redevelop it. For instance, a topographic survey is necessary where a building has been demolished, a quarry land, landfill or another place where activities on land may lead to topographical changes. A topographic survey provides a precise display of how the activities on the land have influenced the topography and help in the better planning of land use.
