LiteMapper 6800

LiteMapper 6800 provides full waveform analysis for an unlimited number of target echoes. Multiple-time-around processing allows the utilization of target echo signals which have been detected out of the unambiguity range between two successive laser pulses. The scanning mechanism is based on a fast rotating polygonal mirror, which provides fully linear, unidirectional and parallel scan lines.

 

LiteMapper laser scanners sample the surface in parallel lines with regular point spacing both in and across flight direction to provide the most accurate surface representation. The scan speed can be varied in a range to provide very dense point spacing within each scan.

 

The continuously rotating scanner used for beam deflexion is resistant to temperature variations and accelerations which typically occur under airborne operating conditions.

 

LM 6800-240 & LM 6800-400

There are two different type of laser scanners which offer different laser pulse repetition rates. LiteMapper 6800-240 has a laser pulse repetition rate of up to 240,000 Hz, LiteMapper 6800-400 has a laser pulse repetition rate of up to 400,000 Hz. Please look at the specifications tab for further information regarding the two models.

 

Easy to use:

Automated data acquisition with LiteMapper is achieved by tight integration with the CCNS4 precise guidance system. The CCNS4 system guides the pilot and controls the data registration during flight, a dedicated LiDAR operator is not mandatory.

 

Both LiDAR and optional digital image data are directly geo-referenced through the AEROcontrol GPS/IMU system that continuously registers sensor position and attitude in flight.

 

Digital Waveform Recording:

LiteMapper is a revolutionary LiDAR system for airborne LiDAR mapping. It is the world's first available commercial system to feature high-resolution waveform digitization and recording. Its ability of waveform analysis for each individual laser beam offers the opportunity of a detailed view into the vertical structure of the surface to the user. Different height classifications become available. For instance, the vertical density at different height levels or the roughness and slope of the surface.

 

Complete Solution:

With a fully digital process chain from primary data acquisition through all processing stages to the final product, LiteMapper provides the basis for efficient production with a return on investment within one year. LiteMapper is a complete solution containing all hardware and software components necessary to create a DTM and a DSM.

  • Complete Solution for DTM and DSM creation consisting of:
  • Optional DigiCAM & DigiTHERM for georeferenced images and thermal images

 

DigiCAM & DigiTHERM option:

Completing the LiteMapper LiDAR system IGI offers its DigiCAM and DigiTHERM systems as option. DigiCAM is a medium-format airborne digital camera system. DigiTHERM is IGI's solution for digital aerial thermography. Both DigiCAM & DigiTHERM are fully integrated in CCNS4 & AEROcontrol for direct georeferencing and automated operations.
