TinyTile.Core 0.0.1

TinyTile

Library for implementing or integrating tile services(TMS WMTS XYZ) in .NET application.

How to use

Intergrate xyz tile services to Asp.Net Core

Suppose Linq2db is the ORM.

[Table("points_of_interest", Schema = "public")]
public class Poi
{
    [Column("id"), PrimaryKey, NotNull]
    public int Id { get; set; }
    [Column("name")]
    public string Name { get; set; }
    [Column("kind")]
    public string Kind { get; set; }
    [Column("geom")]
    public Point Geometry { get; set; }
}

var source = new MbTile(path);
var layerMb = new Laye("points_mbtile_3857", source, gridSet:GridSet.Create(SRS.Epsg3857, schema:YAxisSchema.Xyz));

var pgSource = SqlSource.FromTable<TableAttribute,ColumnAttribute,Poi>(connstring,SRS.Epsg4326,t => t.Name,c => c.Name,new string[]{"0,4,0.2","4,8,0.4","8,16,0.5","16,21,1.0"});

var layerPg = new Layer("points_pg_4326",pgSource,gridSet:GridSet.Create(SRS.Epsg3857,schema:YAxisSchema.Xyz));

services
// AddMvc() 
// AddControllersWithViews()
.AddControllers()
.AddXyz(services,xyzBuilder => {
    xyzBuilder.Prefix = "geo/tiles/xyz";
    xyzBuilder.AddLayer(layerMb);
    xyzBuilder.AddLayer(layerPg);
});

See DemoApp for details.

Demo App

You should firstly create and init postgis database.

cd DemoApp
dotnet run

Visit mbtile xyz service,http://localhost:8088/mbtiles@3857@xyz.html Visit PostGIS xyz service, http://localhost:8088/postgis@4490@xyz.html

TO DO

• Support various mbtiles(1.3 and epsg3857 only now)

• Support render vector data source to raster tile(png,jpeg...) with styles(mapbox style,sld..)

• Support WMTS

• Support TMS

• Support raster data source

• Support various vector data source,eg PostGIS,Shapefile,GeoJson,Tile files,etc
