Crate geojson_tile_renderer 

GeoJSON Tile Renderer

A high-performance Rust library for converting GeoJSON features to PNG tile images using Web Mercator projection (EPSG:3857).

Features

• Render GeoJSON features (Polygon, LineString, Point, and Multi* variants) to PNG tiles
• Web Mercator projection for standard web mapping compatibility
• Configurable tile size and styling
• Async/parallel tile generation support
• Zero-copy optimizations for performance

Example

use geojson_tile_renderer::{TileRenderer, TileCoordinate, Settings, BackgroundColor};

// Create a renderer with custom settings
let renderer = TileRenderer::builder()
    .settings(
        Settings::builder()
            .size(512)
            .background_color(BackgroundColor::white())
            .build()?
    )
    .build()?;

// Load GeoJSON data
let geojson_str = r#"{"type":"FeatureCollection","features":[]}"#;
let feature_collection: geojson::FeatureCollection = geojson_str.parse()?;

// Render a tile
let tile = TileCoordinate::new(10, 163, 395)?;
let png_data = renderer.render(&feature_collection, tile)?;

// Save the PNG data to a file
std::fs::write("tile.png", png_data)?;
