TOTAL STATION

The total station is mounted on a tripod and leveled before use. The other part of a total station, the electronic distance measuring device, measures the distance from the instrument to its target. The total station allows measurement of this type to be taken by simply targeting someone as they move down the avalanche chute (assuming it's safe to do so). The total station provides a quicker solution to this measurement by allowing a light beam to measure the distance instead of a tape measure.

LEVEL MACHINE

Surveyor's level, instrument used in surveying to measure the height of distant points in relation to a bench mark (a point for which the height above sea level is accurately known). It consists of a telescope fitted with a spirit level and, generally, mounted on a tripod. It is used in conjunction with a graduated rod placed at the point to be measured and sighted through the telescope.

GPS

The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites. GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.

RTK GNSS

A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location (longitude, latitude, and altitude/elevation) to high precision (within a few meters) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). The signals also allow the electronic receiver to calculate the current local time to high precision, which allows time synchronization. Satnav systems operate independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the positioning information generated.

3D SCANNER

3D scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colors). The collected data can then be used to construct digital three-dimensional models. Many different technologies can be used to build these 3D-scanning devices; each technology comes with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitized are still present, for example, optical technology, may encounter many difficulties with shiny, mirroring or transparent objects. For example, industrial computed tomography scanning and structured-light 3D scanners can be used to construct digital 3D models, without destructive testing.

SATELLITE IMAGERY

Satellite imagery consists of photographs of Earth or other planets made by means of artificial satellites.. The first images from space were taken on sub-orbital flights. The first satellite (orbital) photographs of Earth were made on August 14, 1959 by the U.S. All satellite images produced by NASA are published by Earth Observatory and are freely available to the public. Several other countries have satellite imaging programs, and a collaborative European effort launched the ERS and Invest satellites carrying various sensors.
