2. Introduction Special GI support system for military teams
Project has started in 2002
Supported by government of the China
Li Zhong

3. Scope of the system Map surounding area Analyse landscape
Find the best solution for military action
Li Zhong

4. Map surrounding area Create digital landscape model of the area
Including
Digital terrain model
Objects on the terrain
Object’s movement (dynamic items)
Li Zhong

5. Analyse landscape Evaluate landscape items Evaluate dynamic objects
Predict possible future situation (state of the landscape and dynamic items)
Li Zhong

6. Find the best solution for military action
Analyse input parameters of the action
Build the possible solutions based on prediction
Evaluate the solutions
Recommend the solution
Li Zhong

7. An action examples Destroy enemy base station Escape prisoners
Find a strategic point and build base station
Li Zhong

8. Components
Hardware (computers, robots, detectors, sensors, computer network, …)
Software (services, clients, adaptive cooperate and distributed components, …)
Data (knowledge base, neural networks, landscape model, …)
Framework (standards, metadata, …)
Li Zhong

9. Robot
Sensors (detectors) – movement, meteorology, radar, photography, video, GPS, EGNOSS, LPS
Move in difficult terrain
Li Zhong

10. Standalone sensors Sensors (detectors) – movement, meteorology, …
Distributed in the terrain by robots or soldiers
Connected by wireless computer network
CPU and memory with web services and clients inside
Li Zhong

11. Computer network
Wireless network
Covers 200 km2
Li Zhong

12. Services Web services SOAP, HTTPS, RTMPS, WS-Security
Cooperate services (service built on other services)
Adaptive services (automaticly generated services based on the situation, based on neural network analysis)
Li Zhong

13. Service examples / 1 Photogrammetry service Radar service
Creates 3D model from set of land photos from the robot’s camera or sensor’s camera
Radar service
Precises 3D model created by Photogrammetry service
Li Zhong

14. Service examples / 2 Movement service Map service
Returns set of information about moving objects in the landscape
Map service
Build interactive 3D scene from Photogrammetry, Movement and Radar services
Li Zhong

15. Service examples / 3 Services in the sensors and the robot
Return set of measured items
Return video sequence
Return image
Analyse situation and build parameters for a new service to develope …
Li Zhong

16. Clients Set of different clients For example:
Virtual Reality client – based on X3D or O2C technology
2D map client – based on Flash or Java applet technology
Video client – shows video from selected robot or sensor
Li Zhong

17. Knowledge base Base for expert system
Set of information how to make best solution for planned military action
Li Zhong

18. Neural networks Used for many purposes
Image analysis – classification, 3D analysis
Radar data analysis
Terrain analysis
Action analysis – support for expert system
Li Zhong

19. Standards OpenGIS, ISO, W3C, OASIS, SGC Interoperability Cooperation
