The second action button of the Toolbar is the Static Layers menu, which provides access to all the time-independent data to the user. Once the user clicks on the menu, two different views are offered: the Tag and Folder mode.
The Tag mode shows the static data as organized by thematic criteria, i.e. the following categories:
- Utilities/Governmental Services
- Administrative Units
- Risk-prone areas
- Hydrography
- Infrastructures
- Exposures
- Land Use
- Topography
In the table below the layers of this category are shown according to the assigned tags.
The Folder mode groups the available data with respect to the categories defined by the Directive 2007/2/CE "INSPIRE":
- Infrastructures
- Health
- Administrative Borders
- Planning
In the table below the static data are displayed coherently with the aforementioned mode:
Every time a layer is pulled on, the application uploads it in the Control Map and the Layer List (top left of the screen). If the cursor is left on the name of the layer in the Layer List, the user enables the tooltip function to open two windows:
- the first one at the top right of the screen which shows the metadata of the layers, such as:
- - name of the layer
- - layer description
- - layer type
In the given example, the tooltip displays the available information about the basin authorities.
- the second one is placed immediately to the right of the Layer List and shows the layer type.
In the following example, a tooltip appears to the right of the Layer List for the basin authorities.
On the left to the name of the layer listed in the Layer List users find the trash-can icon by means of which the previously loaded layer can be deleted. On the right to the layer's name the system offers to the user a set of buttons:
- Turn on / Turn off visualizes / deletes a previously loaded layer
- Zoom to Layer allows the user to bring the zoom back to the default level for that layer
- Legend displays the pop-up window showing the legend for the selected layer
- Scroll offers the user the option to display a set of successive time steps of a given variable within the time range set in the Display)
- Expand allows to display the buttons that activate some additional functions such as:
- - the slider adjusts the transparency / opacity of each layer
