Stakeholders Mapping Service

The “Stakeholders Mapping” service is a birds-eye map overview of the e·Infrastructures organisations currently established and active all over Europe.


Stakeholders Mapping service

The user can choose to display four different types of e·Infrastructures organisations: National Research & Education Networks (NRENs), National Grid Initiatives (NGI), Supercomputer Centres, and Pan-European Coordinating Entities.

Stakeholders Mapping Regions and Countries

Detailed information is available for each organisation in a tooltip which appears when clicking on each visual cue. It is possible to change the map’s zoom level as well as the map type (satellite view, terrain view, etc.). The tool supports visual cues that are distinguishable by users with colour vision deficiencies.


Pan-European Networks Service

The Pan-European Networks Service is a graphical application depicting, with coloured lines on a map, the interconnections of scientific communities. A playback option is available for the user to see how these relations change over time.

Indicators on Maps Service

The Indicators on Maps service allows to depicting indicators on a geographical map, as well as graphs allowing the user to examine interrelations between indicators. The service starts with a default indicator, and the set of all countries defined in [13]. The map is centred on Europe with the range of indicator values presented with a colour set as depicted in the next figure.


Indicators on Maps service (default indicator at start-up: NREN typical backbone capacity)

The service allows the user to view all available indicators in a drop-down list and to select one (indicators window). After the selection, the map is updated to display the selected information (see the next figure).


Indicators on Maps service (selection of another indicator, e.g. Number of Researchers)

The user can view a list (countries window) of all available countries and be able to select one or more. All countries are selected by default at start-up. A select all/none option is provided. The list of countries is a list of 43 European+ countries, which the e·nventory project addresses. In the next figure only the SE European countries are selected.

 
Indicators on Maps service (selection of countries)

The user can also select a specific year from the available range for each indicator. Most indicators are populated with data for the period 2001-2010. The selection is made on the time slider at the bottom of the map. Next to the time slider a ‘play’ button can be pushed to animate (playback motion) the changes over time of the selected indicator.


Indicators on Maps service (selection of a different year)

Moving the mouse over a country on the map brings up a popup containing information about that particular country for the selected indicator (as well as the bookmarked indicator, if there is one). The user can select a country by clicking on it in the map. This will highlight the country in the graph, and can also be used to define a custom region. In the next figure, the mouse is moved over Spain.


Indicators on Maps service (mouse over a country)

Clicking on any of the colours in the legend will bring up a colour selection panel. In this panel the user can change both the colours (either sequential or diverging (see the next 2 figures) colour schemes), as well as the number of colour classes (between 3 and 9). The colour schemes are from the Color Brewer website (http://colorbrewer2.org).

To adjust the data range of the map legend, the user can click on the top or bottom value and then on the popup the user can increment or decrement the value, or enter a whole new value. The intermediate values will be adjusted automatically (see the next figure).


Indicators on Maps service (adjustment of the data ranges of the legend)

image022To bookmark an indicator, the user may click the 'star' button in the indicators panel. The bookmarked indicator will stay even when the user switches to another indicator’s category. This allows to (i) create scatter plot graphs, (ii) compare the bookmarked indicator with indicators from other categories, and (iii) compare two indicators on the map (representing the selected indicator) and the proportional symbol map (representing the bookmarked indicator).

image023To get a data table of a selected indicator, the user may click the 'table' button in the bottom-left corner of the screen. If an indicator has been bookmarked, the data for both the bookmarked and the selected indicator will be displayed. The table also shows the mean, standard deviation and range.


Indicators on Maps service (Data in tabular form)

image025 With the save/export button in the bottom-left corner of the screen, the user can save the current map or graph as an image, or download the data as a CSV file.

image026Click the 'options' button in the bottom-left corner of the screen to open the options panel. A menu appears that allows configuring the map, the graphs, general options and export features.

image027To either switch to full screen mode, or go back to normal panel mode, the user can click on this button in the bottom-left of the screen.

image028 The map zoom controls are normally hidden from view. If the user moves the mouse towards the bottom-right of the screen they appear. To zoom in and out of the map, use the 'zoom in' and 'zoom out' buttons, or drag the zoom slider up or down. Click and drag the map with the mouse to move it to a new position. To restore the map position the button shown on the left restores the map to the original coordinates for the selected region.

image029To open or close the Graph panel, the user can click the 'graph' button in the bottom-left corner of the screen. The same graph button in the graph panel is used to switch between horizontal and vertical bar charts. Use the "sort" button to sort the graph from lowest to highest, highest to lowest, highest to lowest starting in the middle, or alphabetically.

image030 In the top left of the Graph panel the user may find the time series button. When you click on this button, a list of countries appears which you can add to the time series graph. Click on a country to add it to the graph, and click on it again if you wish to remove it. Use the "sort" button to sort the time series labels.

image031 In the top left of the Graph panel, the user may also find the scatter plot button. Clicking on the button will automatically use the selected indicator as the x-axis variable. The user needs to select a second indicator as the y-axis variable. The x-axis and y-axis variables can be selected in the Graph panel, or in the Indicators panel. The scatter plot graph should be better used within the Trends service.


Trends Service

This service displays, on a time series graphs, data for all countries over time. The user may select particular indicators and countries and observe trends on how their values are changing over time. The user can identify the countries that have improved or are still at an early stage in terms of e·Infrastructures over the past years.


Trends service (default indicator at start-up: NREN typical backbone capacity)

The service allows the user to view all available indicators in a drop-down list and be able to select one. After the selection, the graph is updated to display the selected information (see the next figure).


Trends service (selection of another indicator, e.g. Internet Users)

The user can view a list (countries window) of all available countries and may select one or more. This is especially useful whenever the user wants to focus on a specific geographical region of remove from the graph countries to be able to see details at specific value ranges. In the next figure the first 10 countries in the ranking have been removed to see details in the remaining countries.


Trends service (selection of countries)

The Trends service is also appropriate to generate horizontal or vertical bar charts. Animation is possible with the animation button in the time slide.


Trends service (horizontal bar chart)


Trends service (vertical bar chart)

Last but not least, the Trends service is suitable for scatter plots, a very useful graph to identify the correlation between two different indicators.

In the top left of the panel, the user may find the scatter plot button. Clicking on the button will automatically use the selected indicator as the x-axis variable. The user may select a second indicator as the y-axis variable. The next figure shows a strong correlation between two indicators.


Trends service (scatter plot)

The scatter plot can be also animated (see the next figure) to see changes over time, with each bubble (point) moving to the corresponding x and y positions (depending on whether data is available for each time interval). If the “show trails” is selected (next to the play button), each bubble will leave a trail to mark previous positions over time.


Trends service (scatter plot with trails)

A third indicator can be visualized through the bubble size parameter. This indicator can be selected through the drop-down above the scatter plot. The bubble size follows the formula: value/maximum value (see the next figure).


Trends service (scatter plot with a third indicator on the bubble size)

Clicking on a scatter plot bubble will display the associated label. They can also be repositioned through „drag and drop, by right-clicking and selecting 'move text labels or map points'.


Treemaps Service

This is a non-geographical spatial map service for displaying indicators that are hierarchically-structured as a set of nested rectangles. The service allows the user to view a list with all the available indicators and be able to select one. The next figure depicts the National Supercomputing Theoretical Pick Performance for European countries with supercomputers in the top500 list.

Build Your Own Index Service

“Build Your Own Index” is a service that allows the user to custom-build composite indices and create unique country comparisons and rankings by applying, with relative freedom, formulas and weights to the available primary indicators. The user may view a list with all the available indicators and may select two or more. For each indicator it is possible to set a weight (0-100%). Then specific years may be selected as well as a normalisation algorithm and a name for the composite index. The composite index is stored during the session (see the next figure). After the composite index is created, the same functionality of “Indicators on Maps” service is provided.
