The Map Areas tab is open by default when you enter a mission. The currently selected map area is always displayed at the top of the tab, under the Current Map heading. Intially, this is always the connected mission map, but an offline map area may be displayed there if a user has selected one. Below this, you have access to any downloadable map areas that may have been created for use in the mission.
The connected mission map is accessible to all mission members and is always the main map used for any mission. Most of the work done in a mission appears on the live map, and you can access all of the tools used during a mission from the map.
When you access the mission map, your status changes from inactive to active.
Downloadable maps areas are created to support offline use of ArcGIS Mission Responder. These are mission-critical map areas that are created in preparation for a mission in a disconnected environment. They contain a small section of the mission map that can be downloaded and used regardless of connection status, although tools and map functionality are limited by the lack of connection.
If offline map areas have been created for your mission, you may download them onto your device from the Map Areas tab in the mission overview. It is recommended that you do so when first connecting to a mission, as they are not available for download once in a disconnected environment.
