3. The Geomatic Process

4. Geo-data/information Geometry (where?) Thematic (what?) Topology Time

5. Expansion Technology –New Sensors GPS, Ikonos, LiDAR, digital cameras, InSAR –High resolution –From 2D to 3D –Computer technology –Virtual Reality –Telecommunication (Internet) Society –World population –Mobility –Local conflicts –Communication –Food production –Energy consumption –Exploration of natural resources and sea areas –Intensified land use

7. Landsat MSSIKONOS

8. Radar on Ice

9. Digital Cameras of IGN Airborne Digital Frame Camera of IGN Double Swath Colour Camera

10. From 2D to 3D 1. Start from scratch 2. Use existing 2D digital maps

11. 3D = 2D + 1D 2D Digital Map Add Third Dimension Add Texture

12. Laser-Altimetry GPS INS Laser Pulses (80,000/sec)

13. Computer-technology Map -> Files Lines -> Objects Queries –compute fastest route A -> B –find varanasi university –determination of land owner when planning a new road –to monitor transportation –projection of a design on the existing (map) situation

15. Virtual Reality

16. Virtual Reality Functionality

17. GII: geo-information at the source

18. Conclusions Without information people are living in blindness Any geo-science needs geo-data and geo-information to achieve its goals and to tackle today’s complexity of earth- related problems, increasing geo-information is required Geomatics is the science concerned with the developing of technologies and methodologies for collecting, storing, processing and dissemination of geo-data and geo- information The processing of the mass of geo-data emerging from new sensor technologies requires automation
