Research on the Performance Testing of the New Spatial Information Network Access G/S Mode

G/S mode is a brand new spatial data access mode which is especially suitable for spatial information accessing through network. By introducing the software testing theory, a software performance testing on the spatial information network accessing was conducted between the Google Earth based on G/S mode and the Google Maps based on B/S mode. The advantages of G/S mode on the spatial information network accessing can be truly shown by comparing the testing results.
