button.
Each theme is composed of:
- The Live Maps available for the corresponding theme;
- The Layer Transparency for each theme;
- Metadata;
- Map Legend;
- Docked;
- Minimise ; and
- Close.
All themes work in a similar fashion and as such only a selected theme will be explained here. The Live Maps for the selected theme of 'Demographics' is shown below. Ensure the main layer title (Demographics) is ticked to ensure the theme layers are displayed. An individual map layer can be switched on and off by clicking the corresponding check box. Some layers may have been grouped and the group can be expanded to view the individual layers by clicking on the expand button (triangle) to the left of the map layer name.
The available Layer Transparency for selected themes is shown below. The scale of transparency
for each theme can be adjusted by moving the transparency scale bar for the corresponding layer.This icon will bring up a panel where the user may change the transparency of the various themes.
Changing transparency will only have an effect if the theme is visible, i.e. the check box next
to the theme's name is checked. Transparency is adjusted by moving the arrow along the transparency
toolbar, moving the arrow all the way to the right assigns a transparency of 100% to the theme;
moving the arrow all the way to the left assigns a transparency value of 0%.
The Chart Statistics provides a list of layers from which a dynamic graph may be
created and displayed. An option has been provided to only show the graph or show the graph
dynamically linked to the map.
Once a graph is selected from the list, the graph for the selected layer is then displayed and the name
of the selected layer is shown above the graph.
If only the graph option was selected (i.e. dynamically link graph to map is not selected), only a graph will be displayed. When moving the mouse over the data on the graph, the actual statistics and details of each region will be shown as a label.
If the graph dynamically linked to map option is selected, the region from where the data is extracted
for the graph will be outlined and coloured on the map. It may take a while to load the highlighted map.
When the user hovers over data on the graph the actual statistics and details of each region will be shown
as a label and in addition the corresponding region on the map will be highlighted. When one of the graph
feature is clicked, the map will zoom to the selected feature.
To remove the highlight dynamically linked map, close the theme widget, or select chart statistics again.
The user may also export the carted data to a CSV file. To do this he/she must simply click on the

This icon will open a panel where the user may view the metadata
of the various layers. All available data will have their metadata displayed here, independent of
