GeOxygene: An Open 3D Framework for the Development of Geographic Applications

Some others authors also define 3D GIS by a list of functionalities expected. [Pouliot, 2006] said that a 3D GIS must own the same abilities as a 2D GIS extended to the third dimension. In [Pouliot, 2006] [Poupeau, 2008] and [Rahman, 2001], this list is detailed. A 3D GIS has to provide: • Creation and edition of geometric primitives in 3D (point, line, polygon and polyhedron), • Navigation and visualization in a 3D universe, • Loading and exporting different kinds of data, • Geometric and semantic querying, • Geometrical operators : shape transformation (translation, rotation, 3D buffer) and operators between two geometries (Boolean operators, distance operators)
