# vector-tile-cs

C# library for decoding [`Mapbox Vector Tiles @ v2.x`](https://www.mapbox.com/vector-tiles/) ([vector tile specification](https://github.com/mapbox/vector-tile-spec)).

_**Decoding tiles created according to `Mapbox Vector Tile Specification @ v1.x` is not supported!**_

Available as nuget package: [![nuget.org](https://img.shields.io/nuget/v/Mapbox.VectorTile.svg)](https://www.nuget.org/packages/Mapbox.VectorTile)

# Depends

Native C# implementation - no dependencies.

`NUnit` and `NUnit3TestAdapter` for running tests - will get restored automatically when building the solution.

#Example

```c#

byte[] data = //raw unzipped vectortile

VectorTile vt = new VectorTile(data);

//get available layer names

foreach(var lyrName in vt.LayerNames()) {

    //get layer by name

    VectorTileLayer lyr = vt.GetLayer(lyrName);

    //iterate through all features

    for(int i = 0; i < lyr.FeatureCount(); i++) {

        Debug.WriteLine("{0} lyr:{1} feat:{2}", fileName, lyr.Name, i);

        //get the feature

        VectorTileFeature feat = lyr.GetFeature(i);

        //get feature properties

        var properties = feat.GetProperties();

        foreach(var prop in properties) {

            Debug.WriteLine("key:{0} value:{1}", prop.Key, prop.Value);

        }

        //or get property value if you already know the key

        //object value = feat.GetValue(prop.Key);

        //iterate through all geometry parts

        //requesting coordinates as ints

        foreach(var part in feat.Geometry()) {

            //iterate through coordinates of the part

            foreach(var geom in part) {

                Debug.WriteLine("geom.X:{0} geom.Y:{1}", geom.X, geom.Y);

            }

        }

    }

}
