Visiontek MapMatrix multi-source geographic data comprehensive processing system MapMatrixGrid

Platform overview

MapMatrixGrid V2.0 is a powerful digital photogrammetry platform created by Visiontek for team project-level collaborative production. The platform uses a networked collaborative working mode to achieve project-level collaborative work for teams of about 50 people and introduces cloud stereo mapping technology. Eliminating the hardware dependence of traditional surveying and mapping on the stereo graphics card, and with a complete data management hub and project manager module, it can efficiently realize the efficient production of 4D products based on traditional aerial survey data such as drones, aviation, satellite remote sensing, etc., and comprehensively improve 20- 30% team's comprehensive production capacity.

Platform advantage

Team project-level networked collaborative work

The server centrally stores backup data, defines the production process, distributes tasks, and remotely inspects quality. The operating terminal roams the three-dimensional images online, performs DEM editing, DOM production, and DLG collection. At the same time, it refers to the neighboring results to connect the edges faster, effectively improving 20-30 % Team comprehensive production capacity.

The real integration of acquisition, compilation and storage

The platform has configured a professional real estate warehousing plan for users, opening up the boundaries between collection, editing, and warehousing. The same data format is used in all stages to achieve what you get is what you get, and the vector data inspection and editing functions are fully enhanced. , So that the data only needs to be edited once from storage to map output, realizing the integration of 2D and 3D vector acquisition and compilation in the real sense.

Advanced cloud stereo mapping technology

Super-fusion GPU cloud technology is used to construct cloud solid, and the use of cloud driven display of three-dimensional graphics can be realized, the superior display effect could be obtained without any graphics card, which can make the stereoscopic mapping work completely get rid of graphics card dependence, and the cost of 3D mapping hardwares reduced effectively.

Rich DEM editing functions

The platform has rich DEM editing functions and a comprehensive DEM tool set, which can realize the 2D and 3D view browsing, plane editing, three-dimensional editing, cropping, output, format conversion of DEM files with large data volume, and a series of intelligent auxiliary DEM editing operations such as automatic extraction of road, pond range line and house filtration and so on. Such can fully simplify the DEM editing process, and generate the large-scale high-precision DSM results through per-pixel intensive matching.

DSM generated by per-pixel intensive matching

Perfect project management operation 

• Task and data management: strictly manage task data, define the production process in detail, and assign tasks to operators according to map sheets.
• Job monitoring: the administrator can view the task progress and task completion status of the whole measurement area in real time.
• Evaluation of task load: Newly added statistical tools for working days/work area, combined with the number of features, task difficulty coefficient and other factors to effectively calculate the workload of operators.
• Data backup: back up project data regularly, automatically check the validity of the backup data, and support one-key recovery and restore backup.
• Authority management: The administrator specifies the operator's read, modify, and delete authority for project data in detail, effectively guaranteeing data security.

Comprehensive multi-data source support for geographic information

With good compatibility, the platform can not only realize the full process processing of multi-source geographic information data, such as frame image, spaceborne push and sweep image and airborne three-line array image, but also support a variety of image and data import formats, and realize seamless docking with common digital photogrammetry systems in the market.
