Over the past several yeas, the level of pollution has risen so much that it becomes imperative for us to take stringent action against the factors causing pollution.

Today you will see every other person is talking about pollution and global warming. However, we can't ignore the need for large scale infrastructure development that becomes the need of a developing nation. While focusing on this infrastructure development, we most commonly ignore the norms and necessary land surveys required before making a building.



Geophysical survey comes out as the best option at this stage. This is often also known as archaeological survey consisting of a customized type of land surveying conducted to accurately report the findings discovered in an archaeological site or to maintain the relation of the site to the landscape. This geophysical survey is usually done at the demand from archaeologists or government agencies Nike Air Max 90 Premium Sverige , and makes the use of GIS, GPS, aerial photography, and other related methods. Many times Nike Air Max 90 Leather Sverige , these surveys are carried out as remotely as possible to create any disturbance to the archeological site.

While considered primarily at the time of excavation, one important use of archaeological land surveying comes before any of the area has been excavated. Geophysical survey methods can be used to discover the sites prior to excavation. Earlier uses of the land can leave physical marks on the modern landscape, such as raised ridges where the walls of building once stood, however Nike Air Max 90 Ultra 2.0 Sverige , can create maps which show them from an aerial vantage point depicting elevation changes, which can make such features clear. This map then can be turned into a grid which helps in the archaeological excavation of the site.

The objective of geophysical survey is to be as non-intrusive as much as possible. Opposite to many land surveys, it may not be possible for the surveyor to cover the entire landscape on foot because of the sensitive nature of the archaeological finds. The type of survey carried out on archaeological sites is actually known as a 'geophysical survey,' and it may be conducted with LiDAR or other high-tech methods of surveying the area without setting foot on the actual terrain. In some situations Nike Air Max 90 Herr Sverige , specialized equipment can map not only the above-ground artifacts (at the current stage of excavation) but also possible archaeological features buried underground. In the same way as above-ground surveys are constructed, the readings taken from the equipment become a dataset, which can then be rendered as a visible map of the area.

The output of an archaeological survey is a high-resolution image of the terrain. This display can take various forms depending on the intended purpose of the survey. It may be two-dimensional, recording the location of the site and surrounding terrain.
