photomod uasPHOTOMOD UAS allows the user to process UAS data and acquire all types of value added photogrammetric products: DEM, 2D and 3D-vectors, orthomosaics. The main techniques of UAS data processing in the PHOTOMOD system are rigorous photogrammetric processing of images with accuracy comparable with ground sample distance (GSD), and simplified method with absolute accuracies of about tens of meters. 

Functionality, high performance, simplified user-friendly interface and automation of photogrammetric operations are key benefits, allowing the user to consider PHOTOMOD as the optimal solution for UAV/UAS data processing. The system allows the user to improve processing performance due to distributed processing approach, and uses most effectively the computational capabilities available. Block layout creation, cutlines building, tie points search and measurement, as well as DEM building and filtering are available in the system in fully automatic mode.

While there are many advantages of an unmanned survey, the features of the UAV data pose serious problems for photogrammetric processing. The low quality of images, the low accuracy of the on-board GPS / IMU data, the use of uncalibrated consumer cameras and bugs related to the instability of the flight — all this required adding to the PHOTOMOD system special tools to neutralize these disadvantages and to obtain high-quality deliverables.
