概述

• 跨 UI 框架：WPF / WinUI / MAUI / Avalonia / Uno / Blazor / WinForms
• SkiaSharp 渲染，性能优于 GDI+
• 数据源：OSM / WMS / WMTS / TMS / XYZ / Shapefile / GeoJSON / MBTiles / PostGIS
• 几何基于 NetTopologySuite
• 投影：ProjNet / Mapsui.Projections
• 内置交互：拖动、缩放、旋转、捏合、命中

安装

dotnet add package Mapsui.Wpf            # 或 Mapsui.Maui / Mapsui.Avalonia / ...
dotnet add package Mapsui.Tiling
dotnet add package Mapsui.Nts

WPF 入门

<Window xmlns:mapsui="clr-namespace:Mapsui.UI.Wpf;assembly=Mapsui.UI.Wpf">
    <mapsui:MapControl x:Name="MapControl"/>
</Window>

using Mapsui;
using Mapsui.Tiling;
using Mapsui.Projections;

var map = new Map();
map.Layers.Add(OpenStreetMap.CreateTileLayer());

var pt = SphericalMercator.FromLonLat(116.397, 39.908).ToMPoint();
map.Navigator.CenterOnAndZoomTo(pt, map.Navigator.Resolutions[10]);

MapControl.Map = map;

核心概念

类型	说明
Map	地图
Layer / MemoryLayer / ImageLayer / TileLayer	图层
IProvider	数据提供者
IFeature / GeometryFeature	要素（NTS 几何）
IStyle / VectorStyle / LabelStyle / SymbolStyle	样式
Navigator	视图操作

矢量图层

using Mapsui.Nts;
using Mapsui.Styles;

var features = new List<IFeature>();
foreach (var f in geoJsonFeatures)
    features.Add(new GeometryFeature(f.Geometry) {
        Styles = { new VectorStyle {
            Fill = new Brush(Color.Red),
            Outline = new Pen(Color.Black, 1)
        }}
    });

map.Layers.Add(new MemoryLayer("Roads") { Features = features, Style = null });

---

Shapefile

using Mapsui.Nts.Providers.Shapefile;
var prov = new ShapeFile("china.shp", true);
map.Layers.Add(new Layer("China") { DataSource = prov });

---

瓦片图层

map.Layers.Add(OpenStreetMap.CreateTileLayer());

var src = new HttpTileSource(
    new GlobalSphericalMercator(0, 18),
    "https://webst02.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}",
    name: "AMap");
map.Layers.Add(new TileLayer(src) { Name = "AMap" });

// MBTiles
var mb = new MbTilesTileSource(new SQLiteConnectionString("city.mbtiles", false));
map.Layers.Add(new TileLayer(mb));
