Rangefinder

A rangefinder is a device that measures distance from the observer to a target, in a process called ranging. Active methods use passive reflection. Active rangefinding methods include laser, radar and ultrasonic rangefinding. Other devices measure distance using trigonometry are stadiametric and stereoscopic rangefinders. Older methodologies that use a set of known information to make the measurement, have been in regular use since the 18th century. Special ranging makes use of synchronized transmission and travel time measurements; the time difference between several received signals is used to determine exact distances. This principle is used in satellite navigation. In conjunction with a standardized model of the Earth's surface, a location on that surface may be determined with high accuracy. Ranging methods without accurate time synchronization of the receiver are called pseudorange, for example, in GPS positioning. With other systems ranging is obtained from passive radiation measurements only: the noise or radiation signature of the object generates the signal, used to determine range.

This asynchronous method requires multiple measurements to obtain a range by taking multiple bearings instead of appropriate scaling of active pings, otherwise the system is just capable of providing a simple bearing from any single measurement. Ranging is the term applied to distance measurement with moving objects. Combining several measurements in a time sequence leads to tracking and tracing. A used term for residing terrestrial objects is surveying. Applications include surveying, navigation, to assist focusing in photography, choosing a golf club according to distance, correcting aim of a projectile weapon for distance. Laser rangefinders are used for many things today, including golf. People can use this technology not only to measure the yardage of a particular shot but to gauge slope and wind as well; the technology makes it simple to obtain yardage. In a typical rangefinder, one aims the reticle at the flagstick and presses a button to get the yardage. There has been debate over. While their use is banned on the professional level, they are becoming used on the amateur level.

Rangefinders may be used by users of firearms over long distances, to measure the distance to a target to allow for projectile drop. The laser rangefinder displays; until the development of electronic means of measuring range during the Second World War, warships used large optical rangefinders—with a baseline of many meters—to measure range for naval gunnery. Rangefinders are used for surveying in forestry. Special devices with anti-leaf filters are used. Since the 1990s, rangefinders have been used in virtual reality systems to detect operator movements and locate objects. Bradley A.

Doña Juana

Doña Juana is a stratovolcano, located within the Doña Juana-Cascabel Volcanic Complex National Natural Park in Nariño, Colombia. With a previous eruption of VEI 4, Doña Juana is rated as a "large" volcano of "cataclysmic" destructive power. During its last eruption, in 1906, more than 100 people were killed and many houses were destroyed, its largest known historical eruption was on November 13, 1899. In its prehistory, it is known to have erupted in the 23rd century BC in a caldera-forming eruption of unknown magnitude; the name of the volcano originated from a legend of the Chincha Indians, within whose native lands it is located: Mama Juana, a beautiful Quiteña, fell in love with Pedro, a commoner, but with the parents opposed to the marriage, they fled, becoming the victims of a curse that turned them into volcanoes. The volcano can be ascended from a slope, part of the so-called Valley of Orchids, it is surrounded by an area of extraordinary biodiversity, which includes 471 species of birds, bears and pumas.

The summit of Dona Juana consists of a number of peaks, which afford a number of views, including of Laguna del Silencio, one of 42 lakes in the national park. The Petacas is located to the northeast of Doña Juana. Both volcanoes are located between the El Tablón Fault in the west and the San Jerónimo Fault in the east.
