How big are the tiles on a map?

Tiled image overview. Map services such as Nokia Maps and Bing Maps cut maps into square tiles for quick retrieval and display. These tiles are 256 pixels by 256 pixels in size, and are pre-rendered at multiple levels of detail. Many third-party services also provide map-based data that’s cut into tiles.

How to calculate the number of tiles in Bing Maps?

As the number of pixels differs at each level of detail, so does the number of tiles: map width = map height = 2 level tiles Each tile is given XY coordinates ranging from (0, 0) in the upper left to (2 level –1, 2 level –1) in the lower right. For example, at level 3 the tile coordinates range from (0, 0) to (7, 7) as follows:

What do you need to know about the tiling scheme?

The tiling scheme includes the scale levels, tile dimensions, and tile origin for the cache. These properties define where tile boundaries will exist and are important to match when overlaying caches in some clients.

How to overlay tiled images on a map?

That is, you insert replaceable parameters in the base Uri or filename to indicate where to pass the X and Y coordinates and the zoom level for each tile. Here’s an example of the UriFormatString property for an HttpMapTileDataSource that shows the replaceable parameters for the X and Y coordinates and the zoom level.

How to load tiled images from local storage?

You can use the following protocols and locations to load tiles from local storage: Points to the root of the app’s installation folder. This is the location referenced by the Package.InstalledLocation property. Points to the root of the app’s local storage. This is the location referenced by the ApplicationData.LocalFolder property.

What’s the difference between an array and a map?

An Array is a collection of elements of the same data type. The map is a hashed structure of key and value pairs. The indices of the list are integers starting from 0. The keys of the Map can be of any data type. The elements are accessed via indices.

How to overlay custom tiles on a map?

Overlay custom tiles by using the CustomMapTileDataSource. Create tiles programmatically in memory on the fly, or write your own code to load existing tiles from another source. To create or load custom tiles, provide a custom handler for the BitmapRequested event. The BitmapRequested event is raised for each individual tile.

How to display tiles on a map-UWP application?

Display tiles only at certain levels of detail by providing a value for the ZoomLevelRange property. Optionally, configure other properties of the MapTileSource that affect the loading or the display of the tiles, such as Layer, AllowOverstretch, IsRetryEnabled, and IsTransparencyEnabled.

Where do I find custom tiles in maptilebitmaprequest?

Return the custom tile in the PixelData property of the MapTileBitmapRequest, which is contained in the Request property of the MapTileBitmapRequestedEventArgs. The PixelData property is of type IRandomAccessStreamReference. The following example shows how to provide custom tiles by creating a custom handler for the BitmapRequested event.
