Display maps and use locators to enable search and routing offline using a Mobile Map Package.
Use case
Mobile map packages make it easy to transmit and store the necessary components for an offline map experience including: transportation networks (for routing/navigation), locators (address search, forward and reverse geocoding), and maps.
A field worker might download a mobile map package to support their operations while working offline.
How to use the sample
A list of maps from a mobile map package will be displayed. If the map contains transportation networks, the list item will have a navigation icon. Click on a map in the list to open it. If a locator task is available, click on the map to reverse geocode the location's address. If transportation networks are available, a route will be calculated between geocode locations.
How it works
Create a MobileMapPackage using MobileMapPackage.OpenAsync(path).
Get a list of maps using the Maps property.
If the package has a locator, access it using the LocatorTask property.
To see if a map contains transportation networks, check each map's TransportationNetworks property.
