System Of Map And Document Management For Engineering Based On GIS

GIS(Geography Information System)is looked on as information system which can carry out many disposing work, such as obtaining, memorying, querying, dealing with, analyzing and displaying position data relating to earth surface. It has already been used to many fields, for example engineering construction, resource and environment, communication, traffic, military affairs, city planning and so on. Engineering document behave distinct position attribute, especially for city construction or layout designation units, they usually need query engineering item and document including engineering item, file, datum and electric scheme. Nowadays, it is not familiar to all that engineering map and document management makes use of GIS. "System of Map and Document Management for Engineering based on GIS" will discuss these question. GIS is used to engineering map and document management which will produce active action as well as city planning. By analyzing development actuality and trend of engineering document, the article put forward the title "System of Map and Document Management for Engineering based on GIS ".The article mostly study underside contents: (1) Technique character and requirement of "System of Map and Document Management for Engineering based on GIS"; (2) Settling method of the system; (3) Data structure of engineering document management system; (4) Function and interface of the system; (5) System realization method about ArcGIS; (6) Model of "System of Map and Document Management for Engineering based on GIS"; The article can realize some function such as classifying, borrowing, memory, searching and managing datum aimed at engineering electrical document and other form information. Of course, the system is established on the base of GIS. By designing right engineering's item and document management model. Practicing second empolder In ArcGIS, ArcCatalog manage engineering map and space data. Geodatabase is a new object_oriented data model of managing and organising data. Otherwise, making use of ArcCatalog's customization function, it can get a good system interface .Using COM technic, the system establish ActiveX dynamic link (DLL) under Visual Basic programme environment in order to realize specifical system function, finally. These system function is accomplished and realized in ArcCatalog.
