The 3rd ISPRS Workshop on Dynamic and Multi-Dimensional GIS & the 10th Annual Conference of CPGIS on Geoinformatics
Chen, Jun

ISPRS, Vol.34, Part 2W2, “Dynamic and Multi-Dimensional GIS”, Bangkok, May 23-25, 2001
The difference between highway virtual landscape real-time
roaming system and 3DMAX is that virtual system represent
the landscape by the actual earth image obtained by
photogrammetry, have the function of random roam and
attribute inquiring, insert and inquire the illuminating document
somewhere you want.
Highway virtual landscape real-time roaming system uses 3D
entity data structure and manages sorts of complex data. It has
overcome the shortage that the spatial entity can not be
constructed by surface model, especially like the overpass
bridge, pole etc. The structure earmarks of route, bridge and its
appendicular are showed exquisitely.
4 Conclusion
The integrative technology of Photogrammetry and Remote
Sensing and highway CAD has been formed by collection,
management, modeling of mass data and landscape of road
design with high-technology. Highway engineers design
through vivid, realistic image of the earth surface. The quality of
design and the harmonization between design and
environment protecting can be ensured and evaluated by the
new measures and tools. Highway design has been on the
stage from 2D design to 3D design and from static design to
dynamic design with the combination of rich experience of
engineer and advanced technology. The automatization,
visualization and integration highway survey and design has
been achieved.
