摘　　要：基于模型构建器(ModelBuilder)进行模型的搭建,对地理国情数据的更新字段说明进行自动更新赋值,为地理国情监测数据处理提出一种简洁快速的方法。结合2020年地理国情房山区数据,通过使用ArcGIS ModelBulider实现对房山区地理国情数据中的更新字段说明进行自动赋值。结果表明,基于ModelBulider将ArcToolbox工具进行组合形成一个连续的模型,相较于人工赋值可以减少由于操作造成的随机误差,并且在一定程度上提高地理国情数据内业整理工作的效率。A model based on ModelBuilder was built to automatically update and aspoint the updated field description of the geographical national conditions data,which provided a simple and fast method for the processing of the monitoring data of the geographical national conditions.Combining with the data of Fangshan district,the geographical national conditions in 2020,ArcGIS ModelBulider was applied to realize the automatic assignment of the updated field description in the geographical national conditions data.The results showed that the combination of Arctoolbox tools based on ModelBulider to form a continuous model could reduce the random error caused by the operation compared with manual assignment,and improve the efficiency of the internal processing of geographic national data to a certain extent.
