There are many different kinds of surveys but three of the additionally used ones are topographical surveying, land surveying and underground utilities surveys. Exploring and understanding the different types or surveys and surveying is simple when you understand how.
Topographical Surveys or Topo surveying
Topographical Surveying is the study and measurement of the Earth's surface. This may reveal what natural or man-made geographical features exist within an area, large or small, the contours and shapes of the features themselves and also vegetation and the influence of human presence. The thing of all this is to make a three-dimensional map.
In order to provide this kind of accurate detail of the many levels and contours of the land, aerial surveys are conducted, and at ground level survey teams with portable surveying equipment establish vertical and horizontal control points to verify accuracy. In today's world the data is collected and generated electronically.
Fed with the data, computers combine distances, angles, and elevations and produce pictures, using contour lines, hypsometric tints and relief shading.
Land Surveys and surveying
Land Surveying may be the measurement and accurate determination of the 3d positions of varied points on a terrain. The objective of this is generally to find out boundaries. Surveyors produce land maps marking out regions of private, communal or government ownership limits. This is constantly being done whenever there are serious property rights disputes or changes are planned for the region, such as for example for sub-dividing properties, new residential or town-planning layouts, when roads or other engineering structures are planned, or for the determination of ancient boundaries for historical or archaeological purposes.
Underground Utilities Surveys (electricity, Gas, Water and Television)
Underground Utilities Surveying must be probably the most tricky and difficult forms of exploration. Surveyors need to determine what is underground and can't be seen. Before any development can take place it should be discovered what, if anything lies under the ground. These could be drains, electrical or gas cables, sinkholes, water pipes or water pockets or buried tanks.
The first level of exploration would be to collect every drawing, plan or little bit of electronic data designed for the area. This is often not totally accurate, but gives a concept of what installations were situated in the immediate area.
The next level involves picking out visible features, such as manholes, inspection hatch covers, meters, electrical poles, etc. Straight lines showing the shortest distance between them are drawn, which narrows down the search. However these lines cannot continually be totally relied on as rocks along with other underground barriers can cause deviations, and sometimes the pipes or cables don't run from the centre of every inspection element to the next, but slightly to one side or the other.
An indirect survey involves the most recent technology, such as for example radar that penetrates the ground, X-rays, and frequency resonance.
