A video patrol and inspection system is an important part of the government's shipping channel information management. This system is mainly applied to video information gathering and processing as a patrol is carried out. The system described in this paper can preview,edit,and add essential explanation messages to the collected video data. It then transfers these data and messages to a video server for the leaders and engineering and technical personnel to re-trieve,play,chart,download or print. Each department of the government will use the system's functions according to that department's mission. The system can provide an effective means for managing the shipping enterprise. It also pro-vides a valuable reference for the modernizing of waterborne shipping.

To evaluate the project "Research in integrated management and services of urban development records, archives, and information" in progress, this paper analyzes "why", "what", and "how" issues of relevant integration research about integrated management and services of urban development records, archives, and information based on a survey of literature at home and abroad. By a comparative study of current integration research status and features, the author gives a critical analysis of the strengths and weakness of the project and provides recommendations for future *** disciplinary studies indicate that ideals of integration can add values to collaboration, innovation,and optimum in managing evidence, information, memory, and knowledge of built environment cross-culture, cross-discipline, cross-domain, and cross institution for enhancing competitiveness and productivity of business. Cross cultural studies indicate that integrated records, archives, and information management as a whole into capital construction project management process, organizational information resources management systems, and the construction of digital urban development archival repository through service-control, process-control, and product-control are fundamental to guarantee the characteristics and quality of records and records system to support evidence-based e-government,e-business, and the sustainability development of digital city. Present studies on integrated management and services of urban development records, archives, and information have limitations on too much emphasis on integration for collaboration and optimum but not enough studies on integration for innovation and broader use.
