VexTile Mapbox VectorTiles

This project is part of the VexTile vector tile suite. While it is technically a drop in replacement for the original codebase, the namespaces have been sightly changed to avoid confusion.

This project is based on the last version of https://github.com/mapbox/vector-tile-cs. That project has not been moved to modern dotnet and therefore is hard to consume now. We have taken that version and updated the code to be compatible with .Net Standard, 8 and onwards.

C# library for decoding Mapbox Vector Tiles @ v2.x (vector tile specification).

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

#Example

byte[] data = //raw unzipped vectortile
VectorTileData vt = new VectorTileData(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<int>()) {
 //iterate through coordinates of the part
 foreach(var geom in part) {
 Debug.WriteLine("geom.X:{0} geom.Y:{1}", geom.X, geom.Y);
 }
 }
 }
