DP.Blazor.MapLibre.ProjPlugin

Any-projection plugin for DP.Blazor.MapLibre: render a map in any coordinate reference system via proj-wasm (PROJ 9 compiled to WebAssembly).

The plugin runs a self-contained, main-thread reprojection pipeline for GeoJSON and vector tiles — no Web Workers, no maplibre-proj/backproj. The runtime (about 28 MB of WebAssembly plus proj.db) ships inside the package under _content/ProjPlugin/vendor.

Install

dotnet add package DP.Blazor.MapLibre.ProjPlugin

The core DP.Blazor.MapLibre package is referenced automatically.

Requirements

  • The map must be created with RenderWorldCopies = false (the fake coordinate space does not tile).
  • Chromium-based hosts need no extra setup; Firefox/Safari hosts must add the import map from GetImportMapAsync() (see the guide).

Quick start

@using DP.Blazor.MapLibre.ProjPlugin

<MapLibre @ref="_map" Options="_options" OnLoad="OnMapLoad" />

@code {
    private MapLibre _map = new();
    private readonly ProjPlugin _proj = new();

    private readonly MapOptions _options = new() { RenderWorldCopies = false };

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
            await _map.RegisterPlugin(_proj);
    }

    private async Task OnMapLoad(EventArgs _) =>
        await _proj.ApplyReprojectionAsync(new ProjReprojectOptions
        {
            Style = styleJson,
            Crs = "ESRI:54030", // Robinson
        });
}
