THE COMPANY

• Software company based in Barcelona funded in
  1990.
• 25 staff, mainly software engineers and
  geographers.
• Own 3D visualization software since 1997
• Large experience with hundreds of 3D
  cartographic projects
• Close to launch the ultimate technology, v3

THE PROBLEM
Experience on v2
Identification of needs
New technology v3
Optimization plan
OPTIMIZE DATA PROCESS FROM INPUT TO GRAPHIC CARD
CHOOSE ONLY THE RIGHT AMMOUNT OF INFORMATION
HOW TO SHOW HUGE 3D DATASETS SMOOTHLY ONLINE

• TO OPTIMIZE PERFORMANCE
• Powerful Engine
• Flexible architecture

5
THE TECHNOLOGY

• All the Earth in 3D at high resolution.
• Vector and raster layers and 3D elements in
  multiresolution.
• Online distributed datasets.
• Windows-Linux
• Fully customizable, SDK, ActiveX, easy scripting
  (Python based)
• Great interoperability, WMS, WFS, IWS
• Very easy to use.

6
THE ENGINE
Multi-resolution datasets
Distributed datasets
DATA STRUCTURE
Static 4D Datasets With time information
Independent Datasets (MDT, raster, vectors,
names, objects)
SQL databases
Dynamic 4D Datasets (GPS, Obj 3D)
Solar system
7
THE ENGINE
Core independent of UI
MultiPlataform Windows - Linux
SOFTWARE STRUCTURE
C programming Object oriented
Flexible input From outside soft
Open technology (sockets, SDK, ActiveX)
gsScript Own scripting language (Python)
Best software practices
Stereoscopic viewer
8
THE IMPORT MANAGER

• Data structure addressed to independent
  datasets.
• Fast data processing on grid systems.
• Flexible data input by block diagrams.
• Customizing processes by scripting.
• Distributed datasets in different servers.
• Standard formats OGC, WMS, WFS, IWS

9
THE SERVER

• Second generation servers Online-Intranet.
• Client-Server structure based in sockets.
• SSL encrypting security.
• Firewall through http tunneling
