摘　　要：提出不动产登记空间数据库轮廓体更新方法,针对不动产登记数据的管理要求,构建空间数据库模型,依托修剪空间定理和动态查询窗口,识别空间数据轮廓。根据轮廓体更新原理,结合Addpoint_Skycube算法和Deletepoint_Skycube算法,设计轮廓体数据更新技术,再通过临时数据库的过滤,完成不动产登记数据库的准确更新。实验结果显示:所提数据库更新方法的执行时间较短,分别缩短了74.2%与68.5%。完成不动产登记空间数据库更新后,可保证不动产登记过程的完整性。A real estate registration spatial database update method based on contour updating algorithm is proposed.According to the management requirements of real estate registration data,a spatial database model is constructed to identify the contour of spatial data based on pruning spatial theorem and dynamic query window.According to the contour update principle,combined with Addpoint_Skycube algorithm and Deletepoint_Skycube algorithm,design contour data update technology,and then complete the accurate update of real estate registration database through the filtering of temporary database.The experimental results show that the execution time of the proposed database update method is shorter,which is reduced by 74.2% and 68.5%.After updating the spatial database of real estate registration,ensure the integrity of the real estate registration process.
