  1. Geoinformatics The start for solving any geo-related problem Mathias Lemmens Department of Geodesy, Section GIS Technology Delft University of Technology, The Netherlands GIMA Module 1 08/09/09

  2. Delft University of TechnologyDepartment of Geodesy

  3. The Geomatic Process

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

  5. 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 Expansion

  6. Landsat MSS IKONOS

  7. Radar on Ice

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

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

  10. 3D = 2D + 1D 2D Digital Map Add Texture Add Third Dimension

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

  12. 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

  13. Computertechnologie Dual architecture Layered architecture Integrated architecture

  14. Virtual Reality

  15. Virtual Reality Functionality

  16. GII: geo-information at the source

  17. 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
