The EVITA Interactive Map is used to dynamically display the EVITA datasets (Dangers areas and Forecast) selected by means of the EVITA Selector, along with selected Flights and Airspaces impacted (or not) by the selected Crisis.
Forecast is displayed as stacked layers, each flight level range getting a distinct color as defined by the affected areas settings.
Unaffected flights are plotted in Black - the impacted flights being plotted in Red for easier identification - and impacted airspaces are similarly plotted in red, to differentiate from the unaffected ones displayed in Blue:
As for the AIREP, they are also plotted on the map, according to the color code described in the Dossier Tray chapter, and with the Altitude as label:
Important: Simulated vs Real Crisis
When the map displays a simulated crisis, the letter "S" (for simulated) is repeated as watermark across all objects/layers:
When the map displays a real crisis, the watermark is removed:
This chapter is divided in four sections:
Map Layout and Tools
On top of the map itself, displaying the various layers of information,
- Access to the DOSSIER Tray,
- Access to the AIREP Tray,
- Access to the Info Tray,
- The Map Controls.
DOSSIER Tray
The Dossier is a container that can be created, saved to your user profile, retrieved and otherwise edited. The DOSSIER Tray is the management component allowing you to perform all actions linked to the usage of Map Dossier.
AIREP Tray
AIREPs (Air reports on volcanic ash) are a key part of EVITA.
Info Tray
The Info Tray is located in the top right corner of the Map.

Map Controls
A series of controls and indications are grouped at the bottom of the Map display:
They comprise the following features:
Coordinates: Indicates the coordinates of the point designated by the tip of the mouse pointer.
Scale: Indicates the scale of the map as set by the current zoom factor (ranges from 2 NM to 2000 NM).
LevelBand: EVITA objects are defined for a given altitude or range. Make use of this tool to get to see the object as defined at the desired flight level.
Timeline: Navigate back and forth in time and have the objects subject to specific timestamp and validities to visually reflect the changes in the course of the day, the week, the year, ...
Measuring tool: Allows you to measure distances on the map.
Vertical view: Displays the vertical definition for a given selected flight.
Area drawing tool: Used to draw polygons and export resulting coordinates.
Mouse controls
Several mouse actions are available to you to dictate how the content is to be displayed:
Zooming
Wheel controls
Roll up to zoom in - roll down to zoom out
Click controls
Left-Double-click to zoom in - Right-double-click to zoom out
About Zoom factor
(A zoom factor can be assimilated to a zoom "speed" - the higher the factor, the faster the zoom ...)
Zoom In / Out using a scale factor of 2 based on “+” / “-“ buttons of the navigation controller also with corresponding shortcuts on “+” / “-“ and numpad “+” / “-“ keyboard keys:
+ mouse wheel scroll on mouse pointer using a scale factor of 1.5
+ CTRL-mouse wheel scroll on mouse pointer using a scale factor of 1.1
Panning
Click and drag the map in any direction to have map follow the mouse movements.
Plotting on the Map
The objects plotted on the map are selected from the various detached views of the EVITA Portlet and result from actions on their respective Plot Evita / Plot Crisis buttons => please refer to the corresponding sections for more information.
Once imported in the Map, the available objects can be toggled "Showed"/"Hidden" - or removed from the Map - using the Map Dossier.
