Kavel 10 surveys thousands of kilometres of roads every year with our mobile surveying vehicles. These cars are equipped with mobile LiDAR scanners and can collect point clouds under high accuracy while driving allong traffic. In addition to this scanner, the system is also always equipped with a high-resolution panoramic camera that collects footage.
Obtaining accurate pointcloud from a mobile vehicle is very suitable for use in public spaces. Because the vehicle can drive along in other traffic, there is no inconvenience for the other road users. This technique is therefore widely used on roads and other public areas.
Based on this technique, our specialists can process all kinds of products such as DTM’s, drive-through profiles, edgings and other mappings. The technique is also extremely suitable for keeping basic registers of counties, provinces, regional water authorities or national governments.
The collection of the mobile pointcloud is done with our Riegl scanner combined with our 150 megapixel camera. This system that is made up of 6x a 25 megapixel camera makes high resolution images of the environment. Together with the high-quality scanner, this results in a high-accuracy point cloud. On board the cars are also high-quality IMU’s that ensure that the location is accurately recorded. In post-processing, these images and location data are combined into a panoramic image with location data.
The name says it all, we digitize the outdoor environment. These DTM’s are often used for civilian purposes. Based on the collected data, a model in AutoCAD is processed into vectorized line files in NLCS structure. DTM also often refers to a detailed height file of the ground level. In this case, it is used for calculating quantities and heights.
The Digital Topographic File is the digital management map of Rijkswaterstaat. This map shows objects such as signage, lighting, guide rail or marking on the national highways and national waterways. These objects are recorded as line, plane or point objects. Whenever there has been a change in the topography due to works, for example, the DTB needs to be updated. Updating the DTB starts with measuring the changed topography and objects. We can measure the objects with our surveyors, mobile surveying equipment or with our aircraft. The data from our aircraft meets the requirements set by Rijkswaterstaat. The big advantage of measuring with an airplane is that it is much faster than the other methods of data collection. We can take care of updating the DTB up to and including the KernGIS.
