Data collection technology of geographical names and addresses in geospatial framework
The existing unmanned aerial vehicle (UAV) tilt photography faces low collection efficiency during geospatial information collection due to the influence of a large number of the same geographical names and address data. Therefore,a data collection technology of geographical names and addresses in a geospatial framework was constructed. Firstly,a unified coordinate system was used to calculate the chord length accuracy of two adjacent collection points by designing the data collection process of the geospatial framework,and the unified processing was conducted on the address data. Then,according to the description rules of address elements,the collection and filling of geographical names and addresses were explained. Finally,the compilation of internal data and interest points was carried out to collect address data. The validation results show that compared with that of the traditional method,the collection efficiency of the data collection technology in the geospatial framework exceeds 95％,indicating a better collection effect. This collection technology can be vigorously promoted in subsequent similar geospatial information collection.
