Need for topographical survey and its benefits

Topography surveys are used to map and identify all features on the surface of the ground for which the topography survey is being done . It is used to identify the objects and existing features on the ground . All features such a trees, street poles , manholes , walls , wells, utility poles , any structure or nature or made made structure are mapped and noted down . The topography survey will show the size , distance and height of these structures and their elevation level . The topography survey focuses more on the elevation than on the horizontal measurements .

Generally, the purpose of the land survey or topographical survey is to know the land for construction of a vertical structure . The boundaries of the particular land are also marked on the map . The maps are then used by engineers, geologists , architectures , and real estate builders. The fundamental aim of topographical survey is to plan the stages of building or project . It helps to design the layout and know the location of buildings , roads , pipelines , dams , fire control routes , trails , landscapes etc . The results of the survey are not marked as landmark or using stakes , they are marked by using lines on the map of the land , these lines are called contour lines and sometimes , the topographical surveys are called contour surveys.

Today engineers and planner can see the digital version of the map and show to the client the nature of the land and the changes it will go through during design and construction stages .

The Topographical Survey is the first step that is performed before the construction of any vertical buildings . The clear picture of the land used for the construction and the adjacent land is necessary for designing and construction to avoid any legal issue . The survey is also important to know the topography of the land and beneath the structure to change the structure and build a new one .

The topographical surveys are also used when creating the way for drainage , ditches , making walls or for grading , the using the natural landscape for improvement .

The Land Survey Companies come with necessary technology to give the accurate topographical survey report to the client . The land survey is different from soil survey , which is done to know the composition of the soil and creating better construction strategies to ensure the safety and reliability of a building .
