In building the database of objects in digital city management ,survey results need to be converted to SHP format CAD drawings ,and increase further information of the objects ,such as the ownership ,grid coding of location ,object coding .This process involves a lot of data processing operations ,and the flow of data processing is stability and repeatabili-ty.Modeling the data processing of building the database of objects in digital city management using ModelBuilder ,data processing tools can be called in turn automatically by running the model .And this can reduce a lot of repetitive work .%城市部件数据建库是将城市部件外业普查成果CAD图形转换为SHP格式,并增加权属数据、网格编码和部件编码等属性信息的过程。该过程数据处理操作工作量大,并且处理流程稳定,重复性强。使用ModelBuilder 模型构建器制作城市部件数据处理模型,依次调用数据处理工具,可以自动完成数据处理工作,减少大量重复工作。
