BruTile is a .NET Standard library

Demo

Getting Started

1) Create an app and add the BruTile NuGet package

PM> install-package BruTile

2) Create a tile source

// This is an example that creates the OpenStreetMap tile source:vartileSource=newHttpTileSource(newGlobalSphericalMercator(0,18),"http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",new[]{"a","b","c"},"OSM");

3) Calculate which tiles you need

// the extent of the visible map changes but lets start with the whole worldvarextent=newExtent(-20037508,-20037508,20037508,20037508);varscreenWidthInPixels=400;// The width of the map on screen in pixelsvarresolution=extent.Width/screenWidthInPixels;vartileInfos=tileSource.Schema.GetTileInfos(extent,resolution);

4) Fetch the tiles from the service

Console.WriteLine("Show tile info");foreach(vartileInfointileInfos){vartile=awaittileSource.GetTileAsync(tileInfo);Console.WriteLine($"tile col:{tileInfo.Index.Col}, "+$"tile row:{tileInfo.Index.Row}, "+$"tile level:{tileInfo.Index.Level} , "+$"tile size{tile.Length}");}

    tile col: 0, tile row: 0, tile level: 1 , tile size 11276    tile col: 0, tile row: 1, tile level: 1 , tile size 3260    tile col: 1, tile row: 0, tile level: 1 , tile size 10679    tile col: 1, tile row: 1, tile level: 1 , tile size 4009

5) Try some of the known tile sources

// You can easily create an ITileSource for a number of predefined tile servers// with single line statements like:vartileSource1=KnownTileSources.Create();// The default is OpenStreetMapvartileSource2=KnownTileSources.Create(KnownTileSource.BingAerial);vartileSource3=KnownTileSources.Create(KnownTileSource.BingHybrid);vartileSource4=KnownTileSources.Create(KnownTileSource.StamenTonerLite);vartileSource5=KnownTileSources.Create(KnownTileSource.EsriWorldShadedRelief);

6) Use MBTiles, the sqlite format for tile data, to work with tiles stored on your device.

varmbtilesTilesource=newMbTilesTileSource(newSQLiteConnectionString("Resources/world.mbtiles",false));varmbTilesTile=awaitmbtilesTilesource.GetTileAsync(newTileInfo{Index=newTileIndex(0,0,0)});Console.WriteLine($"This is a byte array of an image file loaded from MBTiles with size:{mbTilesTile.Length}");

This is a byte array of an image file loaded from MBTiles with size: 27412
