Syntrophos is the Shared Service Center for the municipalities of Brielle, Hellevoetsluis, Nissewaard and Westvoorne and provides support services in the field of Advice, Finance, ICT and GEO information. Every year Syntrophos has a spring flight carried out that is used for all kinds of management tasks of the participating municipalities. Syntrophos uses the collected data in smart ways to carry out the management as efficiently as possible.
For Syntrophos, Kavel 10 performs the spring flight for several years. This spring flight is distinguished by the amount of data collected during this flight. Not only visual material but also LIDAR is collected simultaneously. This is flown under high requirements with 80/80% overlap.
Kavel 10 has provided us with high quality photos during the first Corona period. Only one person was allowed to fly whilst there weren’t a few windows available to fly. We manage a large area (>220km2) and wanted a simultaneous collection, i.e. LIDAR, Oblique and Nadir flown in 1x with minimal deviations in the different data’s. Despite these circumstances, Kavel 10 has been able to deliver beautiful products through good communication and knowledge.
The distinguishing feature of this assignment is the high data density of the collection. For this project, we fly at a low altitude. This in combination with a large overlap results in a LIDAR point cloud with 40 points per m2 and an orthophoto of 5 centimeters GSD.
Area-wide LiDAR is collected. The lidar data collected is processed by our data specialists into classified files. By means of specialized software, these classifications are assigned to the point cloud. A distinction is made between soil, vegetation, water and building. These classified point clouds are provided as . LAS files to the customer.
In addition to the LiDAR, nadir footage is collected simultaneously. After the input control of the images and the processing of the GNSS/INS trajectory, the images are loaded together with the orientation parameters, camera calibration and fitting points. After loading and processing this data, the final products will be reprocessed. The individual photos will be processed into an orthophoto and stereo photos with the help of the AT.
Oblique images are also collected simultaneously in four directions. These corner photos are ideal for use for the inspection of objects within the project area. The obliek images are processed in the software and then uploaded in our Vision10 viewer. This cloud based viewer gives online access to the images and can be linked to the GIS packages that the customer uses. This allows the customer to continue to work according to the workflow they are used to.
For the client, a 3D mesh has also been made of part of the project area. This photo realistic mesh file is very suitable for 3D management of the area. The 3D meshes can be viewed in various online packages.
