Aerial Triangulation

For most of our photogrammetric applications we use Inpho’s software suite. Aerotriangulatoin is performed with Inpho’s MATCH-AT.

 

This software is a worldwide leading product for automated digital aerial triangulation incorporating fully automated tie point selection, precise multi-ray point matching along with integrated robust bundle adjustment.

 

Further, there is rigorous support for GPS and IMU data, including calibration of bore-sight misalignment, as well as shift and drift corrections.

 

Thanks to its high throughput, unsurpassed accuracy as well as GPS/IMU support, MATCH-AT provides an efficient and highly economic geo-referencing procedure with minimum amount of ground control. Instead of using direct geo-referencing alone, it makes sense to apply MATCH-AT in all photogrammetric projects for processing the image observations together with auxiliary GPS/IMU data. This practise proven method guarantees best achievable and most reliable geo-referencing for all subsequent processing phases; much better quality is available almost without extra costs

 

Photogrammetry

All our photogrammetric data capture is done on Summit Evolution softcopy workstations. The Summit Evolution from DAT/EM Systems International is a user-friendly digital photogrammetric stereo workstation and allows a 3D feature collection directly into ArcGIS, AutoCAD or MicroStation.

 

Since our production workflow is fully digital, the stereo-models captured with our Microsoft Vexcel UltraCam cameras are set-up automatically and rapidly in the workstation.

 

Our operators are trained to follow photogrammetric capture procedures with quality control in place. While a lot of routine work has been taken over by computer power, skilled human intervention is still required to ensure that accuracy is met in accordance with the client’s project specifications.

 

Feature capture

Vector mapping is done with great attention to detail and a rigorous implementation of data capture procedures for obtaining the highest positional accuracy of features measured in the stereo-model.

 

Large scale mapping is essential for engineering projects. It is also a key component in GIS where it is a source containing rich geospatial information necessary for the management of relational databases.

 

Most common features captured are buildings, roads, utilities, vegetation and rivers. We have a long experience in this field, providing numerous organisations with various types of quality vector digital maps.

 

3D Modelling

We can create realistic 3D models particularly over cities: with the mix of photogrammetric data capture and the extraction of imagery taken from various angles over the subject, it is possible to recreate the real world with high fidelity.

 

 Not only is the 3D modelling visually appealing but it is also possible to measure in it: position, dimensions, area can be determined.

 

AEROmetrex has provided high resolution digital aerial imagery and terrain models for various 3D simulation application including scenary pack extentions for Microsoft Flight Simulator.
