El ma peo med ¡ante un escáner láser aerotransportado conocido como lidar (Light Detection and Ranging) ha cambiado drásticamente nuestra perspectiva en la organización espacial de los antiguos asentamientos mesoamericanos, especialmente las ciudades antiguas mayas que están cubiertas por la selva tropical. El mapeo con lidar ha revelado que varios asentamientos mayas fueron densamente ocupados con sistemas agrícolas intensivos como canales, terrazas y campos elevados. No obstante, el lidar no es un método conclusivo para revelartodo acerca de los asentamientos antiguos, por lo que se requiere una serie de procesamientos adicionales en el laboratorio para destacar los elementos arqueológicos. Debido a que la técnica puede producir falsos positivos, así como omisiones, es indispensable llevar a cabo la verificación de dichos elementos en campo. [ABSTRACT FROM AUTHOR]

This paper presents the design, implementation and validation of a laser system for 2D detection of obstacles, indoors and outdoors, using laser radar of Allen Bradley Company (Scanner Safe Zone Laser Multizone). A method for deduction of data frames between the laser radar equipment and proprietary software Safety Coniguration & Diagnostic is proposed. We communicate the laser radar with Player software, enabling its use for robotic applications. We design and implement a software system that lets you use the obstacles 2D coordinates scanned by the laser radar, both text and graphics form, allowing to use it in other applications without limitation. The system is validated tests to measure distances in indoor and outdoor, outdoor obtaining as results, between 94 cm and 5120 cm, an average error of 3.32 cm and interior, between 30 cm and 1500 cm, an error through 0.93 cm.

The article offers information on the use of remote sensing method Light Detection and Ranging (Lidar) for optimization of forest management. Topics discussed include advantages of Lidar, how it predicts forest attributes, first estimation phase of Lidar, spatial differences detected by Lidar and segmentation techniques used in it.
