Title

S3XTANTE, A JAVA 3D GIS FRAMEWORK

Abstract

During the last years the usage of 3D applications in GIS is becoming more popular. Since the appearance of Google Earth, users are familiarized with 3D environments. On the other hand, nowadays computers with 3D acceleration are common, broadband access is widespread and the public information that can be used in GIS clients that are able to use data from the Internet is constantly increasing. There are currently several libraries suitable for this kind of applications.

Based on these facts, and using libraries that are already developed and connected to our own developments, we are working on the implementation of a real 3D GIS with analysis capabilities. In order to get it, we will use:

• Nasa World Wind: 3D Visualization.

• Euclid: 3D geometric framework.

• SEXTANTE: Analysis library.

• Proj4.

• Gdal-OGR.

 

 

Since a 3D GIS such as this can be very interesting for tasks like LiDAR or Laser Scanner point clouds rendering and analysis, special attention is given to get an optimal handling of very large data sets. S3XTANTE will be a multidimensional GIS in which 3D point clouds could be explored and analyzed, even if they are consist of several million points.

We will show additional examples of the applications programmed using this libraries and the possibilities that this kind of developments might have in the future.
