Design And Development Of Drainage GIS In Dalian

With the high-speed development of the society and economy,urban drainpipe networks are being constructed so frequently and greatly that the traditional manual method can hardly meet the demands for management of urban drainpipe networks.As the computer technology development at a high speed,digitization is coming into the fields of our life and work,with digital globe and city gradually accepted by people.Thus the digitization of drainpipe networks information is becoming increasingly important.Be suit for the development of Dalian ,design and development drainpipe GIS .The system integrated with space on the basis of geographical information system(GIS),regarding facing the target and professional knowledge as the basic thought,and applying GIS hotspot technology of the present stage.The target it deals with is the figure and attribute data of drainage pipeline networks in a certain district of a city,and the developing platform is MapInfo 7.5 which is the most advanced desktop geographical information system in the world,using its powerful secondary development language MapX as the main developing instrument.It has actualized the design and software development of the mutual management of attribute and space data and systematic interface.The system can realize the drainpipe networks data of collection and record.At the same time,it will meet the need of the updating function,figure editor,the inquiry function of pipeline networks,the mutual enquiry of the entity and attribute,the conversion with the AutoCAD data,statistic function,the browse and modification of the data base,and the ability of the section protraction.We can obtain needed information of drainpipe networks accurately and rapidly through this system,while accelerating the updating cycle of data and enlarging the sharing extent of information.The establishment of this system has offered an effective managing tool for the development predict and plan decision in the city drainpipe networks.Besides,it has enriched the content of the digital city,and built a solid foundation for the sustainable development of the city.It's quite meaningful for the future.
