Research and practice on key technologies of geographical entity production
This paper took the practical work of the new basic surveying and mapping pilot project in Beijing as the starting point and introduced the key technical methods for the production of geographical entities in Beijing's pilot project from two aspects:the conversion of basic geographic information element data into the production of geographical entity data and the data collection of important geographical entities in mountainous areas.This paper focused on the methods of data collection for important geographical entities in mountainous areas,including three-dimensional(3D)stereo editing-based geographical entity data collection and aerial image stereo-based geographical entity data collection.On this basis,the accuracy of the geographic entities collected by the above methods was verified,and the characteristics and advantages of the methods used were analyzed,providing valuable experience and achievements for the construction of new basic surveying and mapping in China.
