Rapid visualization of global image and dem based on SDOG-ESSG
Due to the limit of the two-dimension and small scale issues, it's impossible for the conventional planar and spherical global spatial grid to provide a unified real three-dimensional (3D) data model for Earth System Science research. The surface of the Earth is an important interface between l...

| description | Due to the limit of the two-dimension and small scale issues, it's impossible for the conventional planar and spherical global spatial
grid to provide a unified real three-dimensional (3D) data model for Earth System Science research. The surface of the Earth is an
important interface between lithosphere and atmosphere. Usually, the terrain should be added into the model in global changes and
tectonic plates movement researches. However, both atmosphere and lithosphere are typical objects of three-dimension. Thus, it is
necessary to represent and visualize the terrain in a real 3D mode. Spheroid Degenerated Octree Grid based Earth System Spatial
Grid (SDOG-ESSG) not only solve the problem small-scale issues limited, but also solve the problem of two-dimension issues
oriented. It can be used as real 3D model to represent and visualize the global image and DEM. Owing to the complex spatial
structure of SDOG-ESSG, the visual efficiency of spatial data based on SDOG-ESSG is very low. Methods of layers and blocks data
organization, as well as data culling, Level of Detail (LOD), and asynchronous scheduling, were adopted in this article to improve
the efficiency of visualization. Finally, a prototype was developed for the quick visualization of global DEM and image based
SDOG-ESSG. |
