The concept of temporal GIS utilizes a space-time cube based on a three-dimensional Cartesian coordinate system to represent spatio-temporal and moving objects. For a space-time cube, the elevation of object is not represented. This paper proposes an approach to visualizing data of flying objects. The proposed approach is a four-dimensional cube (4D cube)(More)
The movement of a city bus is represented visually on a space-time cube by a space-time path connecting mathematical points associating the particular locations of bus stops with the times the bus visits them. In reality, most buses do not visit stops to drop down and pick up passengers on regulation time, thus the points indicating their visiting times on(More)
