Multi-source Geospatial Vector Data Fusion Technology and Software Design

Abstract

Firstly, according to the problem consisting with the uniformity of multi-source geospatial data model and the coding of elements, the method of unified design of geospatial data model and consistent expression of feature code is put forward, and the problem of factor layer conversion and coding in the process of coding is analyzed and resolved. Then, the digital map space vector data fusion system is designed with digital topographic map and digital chart, and the fusion of multi-source geospatial data is realized. Finally, the multi-source fusion geographic information demonstration software is designed; the human-computer interaction interfaces are abundantly put forward to meet the application requirements of multi-source geospatial data at all level.
