                                              Overview

*      Who does Standardisation in GI

*      Why Standardisation in GI

*      Examples (standards in practical use)

*      Applications

                                  Situation: Why standardisation?

*      Many GI data bases available, but distributed in different systems, different models ..

*      Searching for data is still difficult (Metadata!)

*      Access to data still not "fluent"

*      Usability of data can be improved

*      Integration of GI data into all kinds of applications required

*      ..

                                                Who?

                                Standardisation bodies (and others)!

                                       Standardisation bodies







                                              Examples





                                  Open Geospatial Consortium (OGC)



                                      OpenGIS Consortium (OGC)

                                                OGC

                                  Scenario: Distributed Data Bases

                                               Remark

*      Not mentioned: CEN:

  --   european Standardisation body

  --   Stopped GI work to wait for ISO results

*      It is very important because CEN members like GE (I think also CZ?) have to adopt CEN
standards! (but not ISO standards)

                                  Why do we need standardisation?

                                   Heterogenous Models / Systems

                                             Modelling





























                                          Interoperability







                                                How?

                                     Examples of specifications

                                             WMS / WFS























                                               Remark

*      Scenario has changed (distributed processing)

*      Conventionally all the data had to be transferred to a GIS!

                                            How to use?

                                              Examples



















                                       Situation in Practise?

                                  Hundreds of WMS implementations

                                          WFS just starts

                                GML becomes more and more important
