Laser Survey
Lidar (, also LIDAR, or LiDAR; sometimes LADAR) is a method for determining ranging, ranges (variable distance) by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It can also be used to make digital 3D modeling, 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has terrestrial, airborne, and mobile applications. ''Lidar'' is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and Mars Orbiter Laser Altimeter, laser altimetry.

Effigy Mounds Lidar
An effigy is an often life-size sculptural representation of a specific person, or a prototypical figure. The term is mostly used for the makeshift dummies used for symbolic punishment in political protests and for the figures burned in certain traditions around New Year, Carnival and Easter. In European cultures, effigies were in the past also used for punishment in formal justice, when the perpetrator could not be apprehended, and in popular justice practices of social shaming and exclusion. Additionally, "effigy" is used for certain traditional forms of sculpture, namely tomb effigies, funeral effigies and coin effigies. There is a large overlap and exchange between the ephemeral forms of effigies. Traditional holiday effigies are often politically charged, for instance, when the generalised figures Año Viejo (the Old Year) or Judas in Latin America are substituted by the effigy of a despised politician. Traditional forms are also borrowed for political protests. In India, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
