存量数据更新生产地理实体方法
A method for updating stock data in geographic entity production
摘要
Abstract
This study addressed the problem of outdated stock data by proposing and implementing a method for terrain-level fundamental geographic entity production based on block update and entity software transformation.The method centered around the Geoway Entity software and began with preprocessing the existing segmented data(including coordinate transfor-mation,structural organization,merging,and segmentation),while referencing orthophotos to update features and collect geographic entity primitives(such as courtyards,intersections,etc.).Secondly,a data transformation mapping table was constructed.Finally,the geographic entity data was converted and generated using the Geoway Entity software.Addition-ally,an auxiliary tool based on Python was developed for preprocessing,quality inspection,and metadata creation.Practical applications show that this method significantly improves the efficiency of data update and effectively ensures the quality of geographic entity data.关键词
