Lidar
LIDAR - airborne Lidar system for precision mapping
Ofek Aerial Photography owns a new Lidar system made by Optech. This cutting edge and sophisticated system performs mapping using highly advanced methods and has some of the best capabilities in the world.
The Lidar is installed on Ofek air crafts and rapidly scans very large areas within a very short period of time.
Sensor for producing a dense, DEM (digital elevation model) quickly and with high precision.
Every beam reflected from the ground is received containing the following data:
- Precise coordinates of beam hit location
- Precise elevation above sea level of beam hit location
Laser mapping outputs:
- DTM (digital terrain model) - 3D mapping of the terrain at a precision of at least 25cm.
- DSM (digital surface model) - 3D mapping of the ground surface at a precision of at least 25cm.
- Option to separate between mapping layers and create sub-layers
- User friendly interface with all existing mapping and GIS systems
* The system contains an APPLANIX IMU (inertial measurement unit) and advanced processing SW programs for various uses.
Possible uses of the Lidar:
- Precise mapping of large areas in a short time frame
- Special applications for mapping of road, water ways, train routes, and more...
- Quantity calculations such as filling and dredging and raw materials in quarries
- Vision line and ground section analyses
- Mapping and analyzing drainage basins
- Mapping and monitoring electric power transmission lines
- Accurate base layer for producing an updated orthophoto
- Detecting objects and phenomena under vegetation
Ofek has immense experience in executing varied projects with the Lidar system, among them projects for government offices, the Dead Sea Works, the Defense Ministry, and various municipal bodies.
Examples of Ofek projects with the LIDAR:
- Mapping high voltage and ultra high voltage transmission lines for the Israel Electric Corporation
- Mapping urban areas for a cellular company
- Mapping high density built up areas for vision line analysis
- Mapping large areas as a basis for creating orthophoto
