The method of data presentation and interpolation is a basic issue in 3D GIS
which will affect the management of spatial data and spatial analysis. It's a key problem for many functions of 3D GIS. Comparing several spatial data presentations
on the base of others research
the authors propose the simple based geospatial data presentation
abstract geoobjects as point
line
surface
and body. Then their logical design and topological relation are given. For visiualization and rebuilding of geoobject
simple based interpolation methods are introduced.
