Surveying Methods

Methods of Surveying - Land Surveying Information

To a large degree, the extent of urbanization and relative worth of the land determine the method of surveying most appropriate. The equipment used varies with the need and nature of survey.

Compass and Chain Surveying Method

Surveying with a magnetic compass and surveyor's chain was the method employed in most of the original subdivisions of the Commonwealth. Today the method is primarily used for reconnaissance surveys of large tracts.

Electronic Measuring Surveying Method

Electronic distance measuring equipment using light beams coupled with theodolites, enable the surveyor to measure precise angles and distances with greater ease and accuracy.

GPS - Global Satellite Positioning Surveying Method

Sophisticated electronic equipment using orbiting satellites to determine both horizontal and vertical placement on the face of the earth is a relatively new innovation.

Photogrammetric Mapping Surveying Method

Photogrammetric mapping may be developed from aerial photographs and is particularly useful for showing land contours, site conditions and details for large areas.
