•Allow to export to popular multimedia format such as video (.avior .mpeg) or VRML (.vrlor .vrml) that provide the following benefits:
•Do not need to know 3D GIS, simply use intuitive and easy to use interface to operate the 3D model.
•Inherent flexibility/adaptability –these multimedia are 3D cross-platform display and non-browser specific which enable expensive data to be used more widely
•Fast and slow time simulation –Ability to control timescale by incorporating a sequence of captured events into the keyframes(or snapshots) of the motion video
