2. There are many different types of surveys but three of the more commonly used ones are topographical surveying, land surveying and underground utilities surveys. Exploring and understanding the different types or surveys and surveying is easy when you know how.

4. Topographical Surveys or Topo surveying
5.  
6. Topographical Surveying may be the study and measurement of the Earth's surface. This can reveal what natural or man-made geographical features exist within an area, large or small, the contours and shapes of the features themselves and even vegetation and the influence of human presence. The thing of all this is to produce a three-dimensional map.

8. To be able to provide this type of accurate detail of the many levels and contours of the land, aerial surveys are conducted, and at walk out 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.

10. Fed with the data, computers combine distances, angles, and elevations and produce pictures, using contour lines, hypsometric tints and relief shading.

12. Land Surveys and surveying
13.  
14. Land Surveying may be the measurement and accurate determination of the 3d positions of various points on a terrain. The purpose of this is generally to find out boundaries. Surveyors produce land maps marking out areas of private, communal or government ownership limits. That is constantly being done when there are serious property rights disputes or changes are planned for the region, such as 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.

16. Underground Utilities Surveys (electricity, Gas, Water and Television)
17.  
18. Underground Utilities Surveying should be probably the most tricky and difficult forms of exploration. Surveyors have to know what is underground and cannot be seen. Before Home Surveys Rishton may take place it has to 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.
19.  
20. The first degree of exploration is 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.
21. The next level involves picking out visible features, such as for example 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 could cause deviations, and sometimes the pipes or cables don't run from the centre of every inspection element to another, but slightly to one side or another.
22.  
23. An indirect survey involves the most recent technology, such as radar that penetrates the ground, X-rays, and frequency resonance. If uncertainty still persists, the final step is drilling or digging potholes at regular intervals to confirm any of the data collected by the aforementioned methods.
