Spatial Big Data Organization, Access and Visualization with Essg

There are hundreds of spatial reference frame (SRF) being applied, and the great difference among SRFs has blocked the share of global data on planet Earth. A conceptual spheroid of radius 12,800km and a spheroid degenerated octree grid method are applied to produce an earth system spatial grid (ESSG), which is of natural characteristics to be applied as a new common SRF. A triple CTA is design...

It is natural for such application to benefit from general geoscientific data already accumulated in standard GISs. However, these data are n...
