The Study Of The Development And Application Of Urban Greenland Spatial Database

The construction of ecotypic city is main target that cities develop in the 21 centuries. Urban Greenland as the main body of natural productivity in city structure is playing important role in the city ecosystem; therefore urban Greenland builds are catching governments of all countries attention in the world. That our country urban Greenland work has also got taking seriously of the governments at all levels, has made every urban Greenland construction getting development swift. But the number of urban Greenland data is very large, and alternate frequently, disperse in many units, it is very difficult to realize the integrating and unification manage of urban Greenland information. Under this background, structuring the urban Greenland information data model and building urban Greenland database become the very necessary but meaningful job.The paper takes the two projects"Urban Greenland information remote sensing survey and the urban Greenland information management system of Wenzhou city"and"Urban Greenland information system database survey of Shanghai". The author research on GIS space theory, database design and method, and Geodatabase data model and so on. According to detailed and systematical demand analysis, the urban Greenland spatial Geodatabase model is constructed, using with the UML technology. The system of the Urban Greenland Management database is designed and constructed based on the model. In light of the feature of urban Greenland database, some pivotal technique problem, such as loading of Geodatabase data, survey data, data processing and the demonstration of data information are discussed.
