The Need for Topographic Surveys Many people are aware of a land survey but the type of study they are familiar with is that which involves demarcation, and they do not know whether there are other forms of a land survey that exist. There is also the topographical survey which homeowners, those in construction sector or environmental sector can use. 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 hills, ravines, structures, woods, walls, buildings, and also other changes on the natural state of the land. 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 occasionally known as contour studies, and they are usually performed before land ownership changes or may be when the property owner wants to do some developments. Unlike border or residential area surveys, a topographic land survey focuses more on heights than on horizontal measurements. The instruments that most engineers use for this study are the surveying quality GPS device and the electronic EDM instrument. The outcomes of the study are not designated using levels or other attractions as in other ordinary surveys. Alternatively, they are displayed as contour lines on the map of the area. 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. Topographic land studies have several uses. In some cases, they might be required from 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. It is necessary to commence all construction works with a topographical survey so that you can determine the starting point and future improvements.
Smart Ideas: Experts Revisited
A topographic survey is also important when determining the alternative option for drainage channels, drainage or other properties with the natural landscape as the foundation 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. A topographic survey is, therefore, essential before the commencement of any building works.
8 Lessons Learned: Surveys
Besides undeveloped land or developed land, this kind of land survey is also beneficial if the place has been used, but there is intended redeveloped. 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 such cases, this survey will provide an accurate view of the way the land has been changing with its use, enabling greater planning and potential use.
