Research on 3D Visualization of Geographic Information Data in Big Data Environment

This paper introduces a system framework for rapid construction and rendering of 3D virtual environment using 2D GIS data. A large-scale GIS data 3D visualization system is designed and implemented. ArcSDE and SQL Server are used to store data. After extraction, processing and registration of multi-band images, the images are stored in the database in Shape form. SURF feature points were extracted and images were matched. DEM is combined with preprocessed multi-band remote sensing images. It was 3D visualized by AcrScene software. The system can well realize correlation analysis, two-dimensional and three-dimensional attribute correlation query, and big data rendering. After testing, this design has good smoothness, fast response and good picture quality. It has nice interactive features. The system can automatically load and splice terrain data.
