contour is an outline of a mass of land. A contour or detailed survey is done by a surveyor and required before you can start on the design of your buildings.Equally spaced contour lines indicate uniform slope. Closed contour lines with higher elevation towards the centre indicate hills
Compiling Contour Survey Data
It typically depends on the level of expertise of the survey professional, but the gathered data is going to be useless unless it's translated into the standard contour map format. One answer to this quandary is to use specialist computer software, a digital terrain model (DTM). Here's a few rules and directives that govern the deciphering of a contour survey.
The closer the bands are, the greater the gradient of the land. The reverse also holds true Contours do not cross When the spacing is equal, this indicates a uniform section of land There are, of course, many other cues to become familiar with, and only a surveyor can properly provide these contoured survey outlines. Ensure your contour survey is professionally commissioned if you want to build on a complex section of topography. This way, you'll always be able to calculate the volume of soil to remove or add, and know the precise depth of services.
