Scanning lidar sensor is an effective and efficient technique for collecting elevation data across tens to thousands of square miles.
Differences in laser return times and wavelengths can then be used to make digital 3 d representations of the target.
Values range from 90 to 90.
For smaller areas or where higher density is needed lidar.
Valid values are between 1 and 65 535.
Sick ag based in waldkirch breisgau germany is a global manufacturer of sensors and sensor solutions for industrial applications.
It has terrestrial airborne and mobile applications.
Light detection and ranging lidar is a technology similar to radar that can be used to create high resolution digital elevation models dems with vertical accuracy as good as 10 cm.
Color lidar by scan angle lidar points will be colorized using the scan angle attribute.
The company offers 3d lidar sensors 3d laser scanners as well detect environment nearly gap free regardless of whether the objects move or not.
Lidar data are available through the national map download client.
Color lidar by point source id this value will indicate the file from which the point originated.
The color of the points will be determined by the shader option chosen in the workspace.
Sensors can also be deployed on helicopters and ground based or water based stationary and.
