| Abstract:Geographic data have being used in many social fields which makes people deal with information in three dimensions. With the rapid development of Internet, it has been the important mark of information times that data' s management and application are based on the Internet. The emergence of Web GIS has provided an approach for multi-source data. At present, the Web GIS are mainly used to deal with spatial data, while it is seldom used to manage multi-source data.In this research, the characters and development of Web GIS, as well as its general structure system are introduced first. At the same time, GIS spatial data model and its structure are also described simply. The ArcIMS4 has many advantages such as strong function, easy development compared with other popular Web GIS software, it has became first selection in Web GIS application. In this research ArcIMS4 is chosen as development platform, and its structure and communication mechanism are analyzed to prepare for developing Chinese coast spatial data query web site in techniques. On the basis of the collecting literature, the China coast research document database is established. Using ASP and ArcIMS4 the China literature database query web site is constructed, and the spatial and attributive bi-direction query of literature is realized successfully.The success of this system provides a new approach for literature management, query and publishing through Internet, and extends Web GIS application fields. |
