Research And Implementation Of Cooperative Remote Sensing Image Interpreting System

This paper mainly studies on remote sensing image interpreting system. Beginning with analyzing serious limitation of resource isolation in conventional stand-alone interpretation, it searches efficient approach to improve remote sensing image interpreting efficiency. Based on organic combination of RS image interpreting, CSCW, and HCI technology, a cooperative remote sensing image interpreting system (CRSIIS) solution is presented. This system implements different location's resource share, and enhances instantaneity and objectivity of RS image interpretation.CRSIIS is a RS visual interpreting system, with synchronized operation mode for multi-user of different location. Its aim is to implement personnel share, data share, synchronized parallel work, and difficulty co-discuss, consequently to insure instantaneity and objectivity. Pivotal implementations of this system are cooperation-oriented design of RS image interpretation and designing cooperation supporter.According to optimal classification of image view and processing, special strategy algorithms for huge image are brought forward. After designing object model and container model of vector marking, carry out cooperation-oriented marking command management model. Symbol marking is provided by vector symbol volume, which has several data import method and manifold application approach.After forenamed cooperation-oriented design, cooperation handling interface, cooperative awareness interface, and concurrency control interface are defined. These universal compact interfaces ensure cooperation instantaneity using least data stream. Combined with cooperation handling mode and cooperative awareness mode,"advanced additive lock method" is constituted and offers concurrency control mechanism for RS image interpretation. Finally, cooperation supporter is carried out with these modules.Through analyzing big-screen interaction technique background, an untouched-sensitive interaction technique is come true and successfully tested, which makes up interaction vacancy in middle space to screen. It also can be integrated with CRSIIS in three different useful modes.As a typical application situation of CRSIIS, RS image cooperative co-discuss boardroom is proposed, which satisfies multi-user respectively using three different instruments in near, middle, and far space. In the end, many co-discuss boardrooms on different location achieve genuine synchronized RS image interpretation for multi-user.Studies and realizations of these key technologies prove this system solution's feasibility. RS image cooperative co-discuss boardroom proves this system's usability.
