Research On GEOINT Service Architecture And Its Key Technologies

The traditional mapping equipments employ the analog technology to maintain the architecture of transactions and insurance, and the integrated service system of digital geography informatics including the GPS, RS, GIS and VR is gradually replace the traditional ones. At the background of the development of IT technology and other research work in related area, especially the concept of IOT, any place in the world will be intelligent and transparent. It brings the challenge and opportunity to the construction of geographic intelligence. At present, fundamental information of mapping supporting system are acquired from static to dynamic, from aviation to aerospace and the corresponded information processing technologies are also in the development of systematization, serialization, griddling and informatization. But how to achieve enormous mapping work, transact the production process into GEOINT service system, format self-independent, integrated, mature and assorted GEOINT service system are to be solved.Therefore, the thesis aims to construct the GEOINT service system in which region fundamental information acquisition, processing, distribution integration technology are involved to feed the requirements of sharing and allying operation from corresponding business industry world. The target is to make depth research on correlated integrated theory and realizing technology. The core problem is to apply the GEOINT information service and cross-disciplinary methods, and realizing technologies in management science and engineering, and to use mature web service technologies, turn mapping work (regional fundamental information acquisition, processing, distribution) into the GEOINT information services, to realize the web integration of distribution heterogeneous systems and resources conformity of correlated realm, establish foundation of realizing the co-work and intellectualization of Geographic intelligence data, to find and make an access to the resources of technology realizing information and sharing services. We also try to realize broad integration and compensative using and sharing resources by co-working with local industry world, departments and organizations.In this thesis, towards the equipment integration of fundamental information, processing and management, and online publish, we study the architecture of equipment, and analyze the geographic service of our country and abroad. By using the existing equipments and mapping technology, construct regional GEOINT service architecture. In the service architecture, the mapping equipments and fundamental data from multiple departments are integrated. The detailed information includes image of multiple resolution and multiple sensor, DEM vector data and multiple attributes from multiple sources. We concentrate on the following five core problems:(1) The construction of the GEOINT information service system has the problem of efficient acquisition of the Geographic fundamental information in the planning operational regions, so we design and realize the distributive IMINT database management system in according to the efficiency problem of the Geographic information in the planning region of the GEOINT information service, and improve the SUSAN corner detection algorism on the basis of TILE model in ROI. Therefore the efficiency of quick searching of targeting images from a large quantity of grid remote sensing images has improved.(2) On concerning of the question of error processing of vector DEM fundamental data, having realized the DEM gross error detection ways of median filter and extremism filter, put forward and realized "DEM Image Pyramid" quick searching and positioning strategy;(3) "Multi-mode" was achieved of visualization technology for Geographic intelligence information virtual reality. We design VR platform based on the IMINT and Vector DEM data. The research and implementation of the above technologies improved in a large degree the processing efficiency of the fundamental Geographic intelligence of the GEOINT service system.(4) The quick access of the action regional geographic fundamental information is a core problem of constructing such GEOINT information service architecture. In the thesis, we study the information transmitting function of action units'position and status, the remote-sensitive image and multi-resources DEM to improve the efficiency.(5) On the aspect of the GEOINT information management and on-line distribution services, we study a private network development framework on the basis of web, on the establishment of the TCP/IP protocol, have designed the data transmission protocol between mobile terminal and main monitor center, and have developed the corresponding software, which improved the transmission efficiency of the GEOINT intelligence and implemented the web distributive system of the information resources fusion between multi-source GEOINT and the correlated realm.Simulated applications have verified that the solution of these core problems and integration of the GEOINT service technology system improved the application efficiency of the multi-source GEOINT and have a strong influence on providing sharing and interoperation in the corresponding industry world, departments and organizations.
