Mapbox provides maps in 23 zoom levels, with 0 being the lowest zoom level fully zoomed out and 22 being the highest fully zoomed in.

At low zoom levels, a small set of map tiles covers a large geographical area. At higher zoom levels, a larger number of tiles cover a smaller geographical area. Map tiles are stored in a quadtree data structure. At zoom level 0, you can see a map of the whole Earth, and this image is contained in a single tile. At zoom level 1, the single tile you saw at zoom level 0 splits into exactly four tiles so the whole world fits in a 2x2 tile square.

Each zoom level quadtree divides the tiles of the one before it, which creates a grid of 2 zoom x2 zoom. The highest zoom level, 22, is a 2 22 x2 22 grid. Libraries based on Mapbox GL display x pixel tiles by default, while many other mapping libraries use x pixel tiles.

If you're working with Mapbox GL JS but would like to display x pixel tiles, you can also specify that individual Mapbox sources are x pixel tiles in your map's source definition or by ensuring the source's TileJSON is correct.

While a x tile and a x tile cover the same geographic area at any given zoom level, they will appear a bit differently when displayed by Mapbox GL JS versus Mapbox. This means that when a Mapbox GL JS map is zoomed to zoom level 2, it will display the same geographic area as a Mapbox.

Because of this zoom offsetthe appearance of a Mapbox GL JS map at zoom level 1 is the same as the appearance of a Mapbox.

Determining the geographical distance covered by an individual pixel in a map depends on the latitude you are looking at. This table lists the approximate geographical distance in meters per pixel for each zoom level, at different latitudes.

Many modern devices have displays with a pixel density that is much higher than the images they display, and they apply special transformations to make images look good.

For this reason, it is important to note that the values below apply to the pixels in the map tile rather than the pixels on your screen. These numbers are based on x pixel tiles, which are displayed in Mapbox GL-based map clients. The per-pixel value will be different for tiles served by the Mapbox Raster Tiles APIwhich are x pixels by default.

To determine the per-pixel value for x tiles, take the zoom level you're interested in and look at the row above it.

Due to the rapid changes being made in the React Native ecosystem, we are not officially going to support this module on anything but the latest version of React Native.

If you are using an older version of React Native with this module though, some features may be buggy.

Since react-native 0. React Native versions from 0. This MapView component is built so that features on the map such as Markers, Polygons, etc.

This provides an intuitive and react-like API for declaratively controlling features on the map. Tiles can be stored locally within device using xyz tiling scheme and displayed as tile overlay as well.

This is usefull especially for offline map usage when tiles are available for selected map region within device storage. For Android: LocalTile is still just overlay over original map tiles. It means that if device is online, underlying tiles will be still downloaded.

For example:. See OSM Wiki for how to download tiles for offline usage. Place components you that wish to overlay MapView underneath the MapView closing tag. Absolutely position these elements. Create the json object, or download a generated one from the google style generator.

This example displays some of them in a log as a demonstration. One can change the mapview's position using refs and component methods, or by passing in an updated region prop. The component methods will allow one to animate to a given position like the native API could.

This allows one to animate the zoom and position of the MapView along with other gestures, giving a nice feel.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Once all the markers are added to the map, I want to make all the markers visible on the map. How can I set zoom level automatically to make all markers visible on the map all the time, regardless of the distance between markers and no. Could be a race condition where this.

The Spherical Mercator projection stretches the map at the poles to create a square map. This projection significantly distorts the scale and area of the map but has two important properties that outweigh this distortion:. To optimize the performance of map retrieval and display, the map is divided into square tiles.

The Azure Maps SDK's use tiles that have a size of x pixels for road maps, and smaller x pixels for satellite imagery.

Azure Maps provides raster and vector tiles for 23 zoom levels, numbered 0 through At zoom level 0, the entire world fits on a single tile:. Zoom level 1 uses four tiles to render the world: a 2 x 2 square. Each additional zoom level quad-divides the tiles of the previous one, creating a grid of 2 zoom x 2 zoom.

Zoom level 22 is a grid 2 22 x 2 22or 4, x 4, tiles 17, tiles in total. The Azure Maps interactive map controls for web and Android support 25 zoom levels, numbered 0 through Although road data will only be available at the zoom levels in when the tiles are available. The following table provides the full list of values for zoom levels where the tile size is pixels square:. Having chosen the projection and scale to use at each zoom level, we can convert geographic coordinates into pixel coordinates.

The full pixel width and height of a map image of the world for a particular zoom level is calculated as:. Since the map width and height is different at each zoom level, so are the pixel coordinates. The pixel at the upper-left corner of the map always has pixel coordinates 0, 0. For example, when using square tiles at level 2, the pixel coordinates range from 0, 0 to, like this:. Given latitude and longitude in degrees, and the level of detail, the pixel XY coordinates is calculated as follows:.

The latitude and longitude values are assumed to be on the WGS 84 datum.

Even though Azure Maps uses a spherical projection, it's important to convert all geographic coordinates into a common datum. WGS 84 is the selected datum. Adhering to these values avoids a singularity at the poles, and it ensures that the projected map is a squared shape. To optimize the performance of map retrieval and display, the rendered map is cut into tiles. The number of pixels and the number of tiles differ at each zoom level:. Each tile is given XY coordinates ranging from 0, 0 in the upper left to 2 zoom —1, 2 zoom —1 in the lower right.

For example, at zoom level 2, the tile coordinates range from 0, 0 to 7, 7 as follows:. Given a pair of pixel XY coordinates, you can easily determine the tile XY coordinates of the tile containing that pixel:. Tiles are called by zoom level. The x and y coordinates correspond to the tile's position on the grid for that zoom level.

When determining which zoom level to use, remember each location is in a fixed position on its tile. As a result, the number of tiles needed to display a given expanse of territory is dependent on the specific placement of zoom grid on the world map. For instance, if there are two points meters apart, it may only take three tiles to display a route between them at zoom level However, if the western point is on the right of its tile, and the eastern point on the left of its tile, it may take four tiles:.

Once the zoom level is determined, the x and y values can be calculated.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
