Study On Heterogeneous Landuse Planning Spatial Data Integration

GIS is a sort of technical system which can analyze the spatial data synthetically. It contains the parts of collection, storage, management and analysis of spatial data. Data is the most important part of GIS.Many kinds of GIS softwares have been put out to be using since latterly tewenty years, Because they come from many different data formats , it leads the coming of heterogeneous sapatial data. Sourceble spatial data can include these meanings such as different data source, different data formats, different kinds of spatio-temporal data , different kinds of scale (different kinds of definition) and different semantic meanings.With the development of GIS.It is necessary to put spatial data using by the way of sharing and integration. While there is a problem in integrating different formal spatial data.It needs to be raveled out if we want to resolve the problem.Landuse planning data information is the important part of stateland resource and geographic spatial information resource. As the result of landuse planning information by the branch management is held in using only in the department, there is no uniform standard and criterion to complied, .It have not enough information communication and communion that should be make.So it has many forks in semantic definition. Many Landuse planning data information have the characteritic of complicated data structure, more kinds of storage formates and far-ranging distributing. This makes it difficult to integrate the data which is in variant flats.And it comes into being a split which can be called "lone information island". Thereby, it is a important step to how to set up integrated mechanism of landuse planning data.At the same time, how to integrate heterogenous landuse planning data and how to realize the integration and communion of landuse planning data has become the key point of the construction of landsource information.The paper is based on the item of "Province Jiangsu landuse planning database setting". With the propuse of searching after the measure of integrating different spatialdata among the different planning datasource and according to certain data criteria, we analyz and clear up the differences of landuse planning data .Also we put the data into the database by the means of converseing, editting and loading.In the course of integration we converse the multi-datasource data with the means of semantic converse,and integrate the data by the model of Geodatabase.After putting data into the database we manage the data by the spatial data engine.
