DAT/EM Systems International - Summit Evolution

The Summit Evolution 3D digitisers from DAT/EM are affordable, user-friendly, Windows-based, best-in-class digital photogrammetric systems. The tools are powerful, for viewing, analysing, manipulating, and processing 3D geodata. There are three levels of Summit Evolution: Professional, Feature Collection and Lite. Projects may be created from virtually any source of stereo imagery, including aerial digital and scanned film, close range terrestrial, digital sensors, orthophoto, synthetic aperture radar (SAR), LiDAR, and satellite sources. Projects from third-party systems may be imported and brought into production as Summit projects. Projects not already registered in three dimensions may use a pre-existing DTM in the Follow Terrain tool to direct movement of the Summit cursor. Similarly, the Elevate Layers tool can elevate 2D vectors to 3D. Terrain Visualizer gives real-time graphic feedback.

Project management: Summit Status Tracker and the Summit Project Viewer are two additional tools for managing data processing projects. Coordinate Conversion tools add capabilities for managing and transforming project coordinates. Drag-and-drop functionality makes building projects easy.

Image sources and orientations: In addition to manual and automatic interior and relative orientation support, it offers a set of tools for control measurement and processing pipelines for absolute orientations. It supports aero-triangulation results from all common orientation packages, such as Trimble/Inpho’s MATCH-AT. On-the-fly epipolar adjustments from non-frame sensors like Leica ADS40/80 Airborne sensor and earth-sensing satellites using rational polynomial coefficients make stereo project setup straightforward for modern non-standard sensors. Any type of optical imagery is supported, and more are added as new sensors come online: Visual Intelligence Iris camera, VisionMap A3, Microsoft UltraCam, satellites, even SAR and Radargrammetry, Close Range projects, etc. Recent developments include tools for bathymetric correction of imagery.

Imagery: Due to the sensitivity of the production environment to image sizes and complexity, the tool supports a wide variety of image formats, including GeoTIFF and BigTIFF, ECW and MrSID, and other popular types. 64-bit applications virtually eliminate file-size limitations. On-the-fly image adjustments, including epipolarisation and histogram adjustment, maximise usability of the information contained in the imagery.
