Icône de l'outil pédagogique Seam:PRES

Seam:PRES is the part of the SEAMLESS-IF software that provides the functionality to create and view visualisations. A visualisation is a table, chart or map that shows the calculation results of the models included in SEAMLESS-IF. Before Seam:PRES can be used a project has to be created, experiments (scenarios) defined and calculated on the server so that the results are readily available in the SEAMLESS database.

At that point Seam:PRES can be used to retrieve the data from the database and use it to create charts. Depending on the user role, charts can be added and modified (by Integrative Modellers) or reviewed only (for Policy Evaluators).

With the current version of the software (April 2008) a limited number of types of charts and tables is supported by Seam:PRES. However this will be extended for future versions, based on requirements and user requests. Included at the moment are: data tables, column charts, bar charts, line charts, pie charts and spider diagrams. There is also a member states map and a NUTS2 regions map, but these are highly experimental. Additionally Seam:PRES can normalise data for a visualisation or calculate relative values based on a selectable reference.

Visualisations created with Seam:PRES are stored in the project. To start an existing one can be opened or a new one created. Next, a first selection has to be made of the experiments and type of indicators to be used for the visualisation. Seam:PRES will then retrieve the data from the SEAMLESS server and store it locally in a three-dimensional data cube.

The content of the data cube can then be further selected from to create the initial visualisation, followed by adjusting the chart type, the selection, the reference point, and so on, until the desired output has been achieved. At which point it can be saved for future use.
