Exploration Methods: LIDAR

Laser topography, LIDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging) allows determining the distance at which an object or area is located from a known reference point, by emitting a beam of light (laser) which is reflected at the point of interest. The distance is determined from the travel time it takes for the laser beam to travel from the emission point to the object and back to the receiver. This technology allows building clouds of topographical data when shooting hundreds of pulses in a second and survey an area ofland.

GEOX has strengths in the area of airborne services using LIDAR technology. Our staff has extensive experience through more than six years of expertise.

It is important to note that airborne topography with LIDAR has an unsurpassed number of advantages over conventional topography, with respect to runtimes and responsiveness, quality, information accuracy and especially with low costs when surveying large areas.

Similarly, this technology allow generating several products that would be impossible to create with traditional surveying, such as:

• LIDAR cloud points with coordinates X, Y, Z of the study area.
• Digital terrain models (DTM).
• Digital surface models (MDS).
• Contours high level of detail
• LIDAR Intensity image (IR). (True Orthoanchromatic photos)
• Color orthophotos (RGB)
• Orthophotomaps
• Topographic maps

• Cadastre and urbanism.
• Urban, rural and agricultural roads.
• Mass Transport: airports, railway stations, cable cars, underground and others.
• Electrical.
• Telecommunications.
• Drinking water and sanitation.
• Irrigation and drainage.
• Flood control.
• Forest.
• Threats and hazards.
• Oil facilities (plants, pipelines, oil and gas pipelines).
• Mining.
