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.

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).

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.

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.

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.

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).

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.

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.
