OfflineMapPackage Class

Definition

Namespace:

Windows.Services.Maps.OfflineMaps

Represents the map data for a particular geographical region. The data can be downloaded and used offline.

Examples

The following example finds a map packages by using a geographical location. If the map package has not been previously downloaded to the local system, this code asynchronously downloads that map.

Note

The points near a border or large boxes and circles might return multiple map package matches.

private async Task getMapPackages()
{
    Geopoint myPoint = new Geopoint(new BasicGeoposition()
    {
        //Geopoint for Seattle
        Latitude = 47.604,
        Longitude = -122.329
    });

    var queryResult = await OfflineMapPackage.FindPackagesAsync(myPoint);

    if (queryResult.Status == OfflineMapPackageQueryStatus.Success)
    {
        foreach (OfflineMapPackage package in queryResult.Packages)
        {
            if (package.Status != OfflineMapPackageStatus.Downloaded)
            {
                var downloadRequestResult = await package.RequestStartDownloadAsync();

                if (downloadRequestResult.Status == OfflineMapPackageStartDownloadStatus.Success)
                {
                    // do something with the offline map package.
                }
            }
        }
    }
}

Remarks

Use this class to asynchronously find map packages that you are interested in using offline. You can check the status of packages to determine whether those packages exist on your local system. If they do not, you can asynchronously download them to your system.

You can then access that data in system controls such as the MapControl, and from other objects in the Windows.Services.Maps namespace.

Properties

DisplayName	Gets the display name of a geographic location for the offline map package.
EnclosingRegionName	Gets the surrounding or containing region of the offline map package (for example: USA).
EstimatedSizeInBytes	Gets the estimated size in bytes of the offline map package.
Status	Gets the status of a map package (For example, whether the package is downloaded to your local system or not).

Methods

FindPackagesAsync(Geopoint)	Starts an asynchronous operation to find a map package that contains map data for specified geographical location.
FindPackagesInBoundingBoxAsync(GeoboundingBox)	Starts an asynchronous operation to find a map package that contains map data for specified four-sided geographic area.
FindPackagesInGeocircleAsync(Geocircle)	Starts an asynchronous operation to find a map package that contains map data for specified geographic area.
RequestStartDownloadAsync()	Starts an asynchronous operation to request the download of a map package to your local system.

Events

StatusChanged

Occurs when the status of an OfflineMapPackageQueryResult changes.
