MAP-3D is a 3D virtual reality system by integrating some entities such as spatial data, building, road, road appendage (mark and traffic lights, etc.) and afforestation. This system, which is used in quick display of mass 3D data, adopts OpenGL database technology. Users can observe real scenes from different heights and angles at different locations by means of walking, vehicles and flying so as to achieve unparalleled real feelings. This system can be applied to urban planning and construction, road / highway planning and design, road traffic management, digital zone, highway information management and other fields. Besides, users can also use secondary development interface program (MAP-3D SDK) to embed this system into their own.
1)Observing angle can be rotated in any way in 3D scene according to different requirements, and observing location can be moved and changed.
2)Supporting 3D data conversion of “UC-win/Road”. Furthermore, 3DS format can be loaded into this system to provide various sources.
3)Introducing SQL SERVER 2000 in local area network (LAN) into 3D data centralized management so as to achieve the goal of data sharing.
SQL SERVER2000 Data Management
4)LAN users are entitled to two identities as "advanced user" or "general user". Advanced users are entitled to create / edit / delete data while general users are permitted to browse data, but cannot modify, edit and delete data.
User Registration and Permission
5)The location and extent of 3D data can be shown at the digital map, and 3D data can be downloaded by a mouse.

6) Allowing to Insert model or tree at any position, and furthermore this model or tree can be deleted, moved and rotated.
Inserting Model or Tree at any Position
7)Allowing to insert model or tree in groups along a road, and furthermore this model or tree can be deleted, moved and rotated in group.

8)Supporting various transportation means such as driving, walking and flying.
Driving Simulation (changing speed and lane by means of direction key)
9)Simulation can be conducted in rainy, snowy, foggy, windy day and other weather conditions.
10)Supporting scenic position saving so as to rapidly realize scenic conversion.
11)Be able to achieve the simulation of flashing/mobile variable signs along a road.
Setting and Simulation of Flashing Variable Signs (5 flashes at a maximum)
Definition and Simulation of Mobile Variable Signs
12)Be able to realize movable model simulation.
13)Supporting to add mark in terms of requirements.
