3D Geographic Information System - realized by the year 2001 from DESS AIST (Paris University, ENSG

Project realized by the year 2001 - DESS AIST ( Paris VI - ENSG) - France

"Computing applied to the Earth Sciences"

Why this Web site ?

The display of spatial in 3D and the GIS - Geographic Information System - are in full rise.

This site is aiming to highlight the 'savoir-faire' of the actors-students, having developed this project.

It comprises the Geomatic and GIS principle taught at the DESS "computing applied to the earth Sciences", du Laboratoire d'Informatique des Sciences de la Terre (L.I.S.T.),University Pierre and Marie Curie, Paris VI, France - National School of Geography.

Project Description

This project comprises the development of 3D Geographic information System core.

It has been realized in 5 weeks full time, with 24 teams composed of 2 to 4 students, so 72 peoples all linked on the same project.

The Digital Terrain Model (DTM) characteristics are as follow :
resolution = 25 m

dimensions = 15 km by 20 km.

21 themes were displayed using the same interface.

It has been developed using JAVA and the library JAVA3D.

Project organization

1 team to coordinates the overall project, GUI and the 3D :

This Team was responsible for the 3D engine development, the main GUI and the interfacing between all the team.

1 team to optimize the project :

This team is in charged of developing an optimizer capable of increasing, controlling the access to the data. They also develop a tool box used by the other module.

1 team for the exchange format :

This team controls the format standard used to store and manage the use of data between the various modules.

21 team responsible for the 3D display of 21 themes :

Bitmap wrapping

2D graph wrapping

Toponymy in 3D

Oriented 3D relief model

Furtive flight at sight

Fluid network
