Gauss uses contextual topographic measurement methods and state-of-the-art equipment using LIDAR (Light Detection And Ranging) technology for the measurements made. Our company has a state-of-the-art LIDAR Trimble MX2. The device is made up of two LASER units capable of recording 72,000 georeferenced / second, a LadyBug 5 panorama camera, which sums up six photo sensors of five MPixels each, very performant and two Trimble Zephyr GPS receivers 2. The device is mounted on a car permitting its use on a very wide range of reliefs. The protocols for using the device are as follows:
1. Identification of the objective from the office using cartographic material.
2. Establishment of an optimal route for scanning taking into account the particularities of the land such as vegetation areas, obstacles, etc.
3. Identification of the goal in the field and modification of the route.
4. Custom Scanning.
5. Download and process collected data.
6. Vectorization and elaboration of the situation-related plans.
The use of LIDAR solution versus conventional methods allows topographic elevations to be made in a much shorter time and with a lower human resources.
Also, stored LIDAR measurements can be used later for a purpose other than the initial one.
