Influence of new technologies on the work with Geo-spatial data

  1. 1. Siberian State Academy of Geodesy Influence of new technologies on the work with Geo-spatial data Associate prof. Katsko S.Yu. s.katsko@ssga.ru Novosibirsk, 2010
  2. 2. Today The number of tools to geo-analyze is growing To use it we need a good GIS-knowledge 2
  3. 3. E-geo-space GIS-training modern level technology c2c-geoinformation geospatial data 3
  4. 4. GIS-structure Hardware Software Data Technology 4
  5. 5. Hardware 1) smaller devices; 2) increase productivity; 3) in first time work only professionals. 5
  6. 6. Software database systems GUI for users-not-professionals complexity of GIS-programs 6
  7. 7. Spatial Data artwork of cartographers 7
  8. 8. Spatial Data Digital Eath 8
  9. 9. Technology concept «User-generated content» 9
  10. 10. New Trend All for users! 10
  11. 11. Geo- in Web 2.0 Web-site Ushahidi, mashup, crowdsourcing 11
  12. 12. Geoinformation Information Spatial information Geoinformation 12
  13. 13. Geoinformation Geoinformation is coordinate information on geospatial and its facilities. 13
  14. 14. Cartographic image cartography geoinformatics geoinformation cartography a new look at the meaning of “cartographic image” in regard to its displaying, perception and availability in new conditions 14
  15. 15. Cartographic image as a product 15
  16. 16. Electronic cartographic image Cartographic image visualize the quality of real objects and phenomena, as well as their forms, sizes, location, and semantics. A computer-visualized cartographic image is a pattern-based and can be generated, scaled, generalized, metrical in particular projection, oriented to visual perception of the person. 16
  17. 17. Traditional and electronic cartographic image Map + Mt, Me = cartographic image map legend The cartographic image of . traditional map consists of graphical elements points lines areas Electronic map consists of digital presentation of graphical primitives graphical elements: pixels and vectors 17
  18. 18. The interaction of man and cartographic image Traditional cartographic The person separates image the cartographic Map legend objects, comprehends Electronic its properties, and cartographic image composes the cartographic patterns hardware, software 18
  19. 19. Geocoded databases Geocoded databases The advent of geoinformatics has provided for data transferring of spatial objects and phenomena from the cartographic image to geocoded databases and generating the geoinformation (digital) terrain model (GTM) 19
  20. 20. Digital map The person “teaches” a computer to draw an analogy between database records and cartographic objects. As a result, the computer gets a possibility to perform those metrical and analytical operations on user’s request, which only the person was formerly able to perform them on a traditional map. Accordingly, digital map is appeared. A digital map is defined as a dynamical object. It is formed by software as complex of GTM and electronic cartographic image. 20
  21. 21. Terrain models 3 computer terrain models are made in geoinformation mapping:  geoinformation model (GTM);  electronic map (EM);  digital map (DM). 21
  22. 22. Features of Geoinformation 1) is information about a specific geographical area; 2) in the space-time coordinate system; 3) digital form. 22
  23. 23. Features of Geoinformation phenomenon objects processes geographical geometric features data 23
