Publishing System Research And Development, Based On The Mapping Results Of The Network Information

The distribution service system of mapping production is one significant part of the construction of provincial geographic space infomation fundamental frame. For coming into being a national connected, continued, easy to expand and distributed maintenance system, we need the unified design and technical requirements to create this system in different areas of China.Based on the needs of the provincial mapping data distribution, this thesis designs the structures of the mapping metadata database and data sheets. According to the situation of existing data, we develop two ways for the data collection and conversion. Upon completion of the metadata database, we develop CSW interfaces for exchanging mapping data, so the State Bureau of Surveying and Mapping and other data nodes in this special network can call WebServices through these interfaces to update the data automatically. This system opens to public with a website running on the Internet for releasing the metadata index both in text and graphics ways, ordering the data on-line, approval with the automatic process. This website uses AJAX, the pyramid structure of the map, cache technology and workflow technology so that the efficiency of the graphical data presenting, searching and position obviously improved, and the order on-line function also strengthens the capability of data distribution.This thesis provides the necessary information and technical guidance, and defines the the design principles, system architecture for the establishment of the distribution service system of mapping production.
