Electronic Distance Measurement

It is excellently suited as a text for undergraduate and graduate students and an invaluable reference for practicing surveyors geodesists and other scientists using edm as a measuring tool.

Electronic distance measurement. More product details close. The digital bubble vial provides a visual reference when measuring horizontal distances. This text gives an up to date introduction into electronic distance measurement edm with a comprehensive review of modern equipment and procedures. And it fits in any pocket for easy access.

Normally these used to measure long distances within 100km with their frequency range. Electronic distance measurement edm is a method of determining the length between two points using electromagnetic waves. Edm is commonly carried out with digital instruments called theodolites. Edm instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers.

Electronic distance measurement edm is a method of determining the length between two points using phase changes that occur as electromagnetic energy waves travels from one end of the line to the other end. What is electronic distance measurement edm. It is accurate up to 1 16 in. Thanks to its laser precision technology and real time measurement mode it takes instant and reliable measurements up to 135 ft to size up the job in seconds.

Electronic distance measuring instrument is a surveying instrument for measuring distance electronically between two points through electromagnetic waves. It is an instrument that combines the angle measurements that could be obtained with a traditional theodolite with electronic distance measurements. Does everything a theodolite does but measures distance accurately using a laser beam reflected from a mirror. This gives great precision when surveying.

The main instrument for surveyors on site today is the total station which is an example of electronic distance measurement. 8 9 field procedure of electronic distance measurement 8 10 geometry of electronic distance measurements 8 11 edm without reflecting prisms reflector less measurements.
