2. Traditional surveying and mapping manual tasks are replaced by software implementations New technology provide new possibilities based on the classical concepts Lack of specialists facilitating the use of the huge amounts of spatial data Geoinformatics study programs – mostly derived from land surveying, mapping and cartography

3.  Geoinformation technology professionals  In MS programmes: not only users of technologies to run applications, but developers both technologies and applications  Project-oriented approach to geomatics education

4. ACTIVITYDESCRIPTION 1. Applications development 2. Data acquisition 3. Data analysis and interpretation 4. Data management 5. Visualization 1. Identify and develop tools and instruments to satisfy user needs 2. Collect geospatial and related data 3. Process data to get information for decision-making 4. Catalogue, archive, retrieve, and distribute geospatial data 5. Render data and information into visual geospatial representations.

5. Two major problems creating „vicious circle“: – lack of true specialists in spatial data systems with overall understanding of GIS technology specialists understanding the new solutions are bound with commercial companies – difficulty to provide students with the ability to study the technologies with as little limitations as possible teachers are not able to address concepts of software implementations  production of users of the commercial systems rather than new specialists How to escape the circle ?

6. Should be used with care in teaching of basic GI concepts as it tends to  operate and interact with closed software products through different kinds of buttons and text fields  hide internals of the solution inclining them to be considered unimportant or even disturbing

7.  Should be preferred against GUI at university level programs in geoinformatics  play a vital role in informatics  required for four from all five activities  how to read and navigate through an code and use it in order to get the desired spatial information  A one mean: research software platform GRIFINOR  Used in new MS courses in geoinformatics at Aalborg University and at Charles‘ University in Prague

8. geographic, spherical and Cartesian geocentric coordinates inverse cartographic projections representation of geopotential based on spherical harmonics spatial subdivision used in indexing, which is a crucial concept for databases with huge amounts of data convenient data representation (simple data structures as well as advanced object-oriented representations) process of data analysis web-based mapping 3D visualisation

9. System of a “real” virtual reality Generalization of the task of providing geoinformation resulting in a geometric model of the reality, instantly visualized in an interactive geo-referenced 3D scene Linkage of the 3D model with – data stored in databases – analytical functions – resources available on the Web Interoperability: supports the most used data representations and processing functions Open source 3D virtual globe platform

13. GRIFINOR is provided over the Internet in form of source code in Java language With use of integrated development environment (Eclipse IDE), the source code can be explained and demonstrated visually Individual components are hierarchically organized

14. Examples of potential themes: 1. Coordination systems:  Georeferencing initiative available on the web  Improvement of the topo surface representation  More map projections to drape image on the surface 2. Application oriented data analysis 3. Visualisation  Rendering of video and sound data in 3D scene  Influence of rendering parameters (e.g. lighting, color)  Multi-resolution representation of lines  Path definition for motion through the 3D scene

15.  can be used freely by anybody interested  under Lesser General Public License  universities have a duty to use such kind of software for three reasons  direct students on the path to self reliance and NOT to end as a qualified user of icons  higher quality of education  can be cheaper

16. Everybody is invited to try GRIFINOR and point out its weaknesses and drawbacks for education in practice at www.grifinor.net www.grifinor.net THANK YOU FOR YOUR ATTENTION!
