What is a level survey?

plane survey is a common method of calculating the soil composition and topography, which includes the consideration of the specified area of ​​the soil as a flat plane. This kind of soil survey works best for small areas of land, largely because the Earth is not really flat. A plane survey on a huge area of ​​land is likely to be inaccurate because it is unable to charge the natural curvature of the country. In some circles, air surveys can also be soil, what is done by aircraft, also call the "survey of planes", although this use is less common.

engineers and citizens have many uses for professional land surveys. Soil surveys provide topography details and help builders estimate the distance, density and depth of soil with great accuracy. The level survey depends on visual markers and individual calculations.

In a flat survey, the soil evaluated is considered to be a flat flat. Inspectors use different tools to place the point on this level, known as JAKO flat table. Then they will use the principles of plane geometry, trigonometry and algebers to calculate the relative distance between points, density of certain topographic traits, such as mountains and depths of the ravine and other soil indentation. The level survey can also be known as the survey of the planes.

The calculations of the level of the planes table are very important for a wide range of projects of civic buildings and mapping. Inspectors use flat techniques to ensure that buildings, highways and other structures are built on a solid and logical way. An accurate survey is also one of the reasons why modern urban blocks are usually approximately about the same size and that the streets run so often parallel. Many GPS units are programmed with data collected also by aircraft inspectors.

Most of the time, the aircraft survives are only suitable for relatively small areas of soil. For example, the neighborhood canBeing scheduled to survey aircraft, but the whole city may not be - at least not all at once. For the most part, this is because the plane survey assumes that the Earth, as can be seen, is a flat plane.

Surrtantics who only deal with small areas of soil do not usually have to worry about the curvature of the Earth, because this curvature is very fine. Despite the larger orders of the soil, however, not to take into account the curved surface of the Earth can lead to results that are more than a little inaccurate. Extensive land research generally requires more specialized tools and more complex mathematics.

The term "plane survey" can sometimes refer to soil surveys carried out by air, plane. Most of the time, however, this kind of supervision is simply known as "air supervision". It is primarily used as a form of monitoring, not as a means of measurement and calculation of ground distances.
