The most precise and efficient method of remote sensing, it provides detailed and comprehensive data about underlying surface.
Simultaneously you receive both visible land surface (vegetation, power lines) and true ground relief.
DETECTION OF HIDDEN OBJECTS
High density of measurements allows to break through the uppermost layers (woods, greenery) and detect the objects, which are visually unnoticeable and exactly define their physical dimensions.
Laser scanner frequently sends the impulse and notes its reflections.The objects of different density reflect impulse with different intensity, that is why it is possible to define objects of different materials.
DETECTION OF OBJECTS DIMENSIONS
The accuracy is within 1 cm (both plain and vertical).
3D model of the ground surface, obtained after aerial laser scanning, allows to see the objects from different perspectives.The speed of data processing is less than 1 hour from the moment of aerial laser scanning.
Frequency – 500 measurements per second
Measurements density – 250 points per square meter.
Laser aerial scanning is especially effective for inspection of mines, power lines, detecting surface relief under heavy and dense vegetation.
For multi-level analysis of underlying surface simultaneously with laser scanner you can use video camera, photo camera, multispectral camera and thermal imaging camera.
