This example demonstrates interactive masking of OpenStreetMap tiles over a stamen.com toner base map, controlled by user-drawn polygons. Using Leaflet’s draw control, users create shapes that act as SVG masks, revealing or hiding the underlying OSM tile layer. The visualization also applies SVG filters, such as grayscale, hue rotation, and sepia, to the map tiles, and offers a selection of hatch patterns for the mask fills. The code integrates D3.js (v3) for projecting GeoJSON geometries into Leaflet’s coordinate system and manipulates the SVG `defs` and mask elements directly.

AI-generated description

Dynamic tiles masking on Leaflet maps. There is no sync when zooming for now, but I hope to add it after Leafle 0.8 will be available. Works only in firefox. Patterns used for creating masks.

Dynamic tile clipping and more

This example demonstrates interactive map manipulation on a Leaflet map centered on Moscow. Users can draw polygons to dynamically clip OpenStreetMap tiles layered over a Stamen toner base map. The code uses D3.js to project drawn GeoJSON geometries via `d3.geo.path` and `d3.geo.transform`, applying the resulting path as an SVG `clipPath` to reveal the OSM overlay only within the drawn shapes. Additional SVG filters and patterns allow real-time effects like grayscale, hue rotation, and hatching on the map layers.

Dynamic pattern animation

This example demonstrates interactive map-based drawing with dynamically animated SVG patterns. Users draw polygons or rectangles on a Leaflet map, selecting between none, diagonalHatch, or diagonalHash pattern fills via a dropdown control. The D3.js library animates the selected patterns—diagonalHatch drops and diagonalHash spins—while a separate toggle applies a blur filter to reveal hardware acceleration differences across browsers. Rendering uses Leaflet’s SVG overlay pane, with controls built through Leaflet’s L.Control extension API.

Vector Tiles

This interactive map displays vector tiles of road networks from OpenStreetMap, rendered as SVG paths. It uses Mapzen’s vector tile API to load road data, and d3.geoMercator’s projection with a d3.tile-based tile system to fetch and display 256×256 tiles. The visualization supports pan and zoom via d3.zoom, with a matrix3d transform for scaling and translation. Mouse movement updates a location readout showing latitude and longitude, computed by inverting the projection.

Leaflet.js × D3.js × geojson-vt.js - Redraw Canvas Tiles Map

This example shows a slippy map interface using Leaflet.js alongside D3.js to render geographic boundaries from a GeoJSON dataset. Canvas tiles are generated in the frontend, converting vector data into raster tiles on demand. The core function `addCanvasTile` leverages the `geojson-vt.js` `tileIndex.getTile` API to extract features for a given zoom level and coordinate. Drawing occurs directly on HTML5 canvas elements, and the code uses Canvas `getImageData` to enable click detection on rendered polygons, with D3 selection handling mouse events for property feature identification.

Raster & Vector 4.0

This example shows an interactive map of the United States with OpenStreetMap raster tiles overlaid by a vector outline of US counties. It combines zooming and panning with a Mercator projection. The code uses D3 v4.0 alpha, the d3-tile library for tile loading, and d3.geoPath with TopoJSON to render county boundaries. As the user zooms, the vector path’s stroke-width adjusts to maintain a constant screen-space width, while the raster tiles dynamically load from OpenStreetMap servers.

d3-tile wrapping

This example displays an interactive SVG world map using tiled raster images from OpenStreetMap, with tile-wrapping toggled by a checkbox. The visualization relies on the `d3-tile` library’s `tile.wrap` method to generate tile coordinates, and `d3.geoMercator` with `d3.geoPath` for the projection. An HTML form checkbox controls the `wrap` flag, triggering a `loadTiles` function that rebuilds the image layer. Each tile is fetched from the `a.b.c.tile.openstreetmap.org` subdomains. The map’s scale and translation are computed and applied via SVG group transforms.

Vector Tiles

This example displays vector-tiled map data, rendering both road networks and building footprints over San Francisco. The visualization loads GeoJSON tiles from an external OpenStreetMap vector-datasource service and projects them using `d3.geo.mercator` and `d3.geo.path`. It employs the custom `d3.geo.tile` helper to compute visible tile coordinates at the current zoom level, then asynchronously fetches and draws each tile’s features as SVG paths. Road types are distinguished by stroke colors, while buildings appear as solid black polygons.

Map Tiles in D3

This interactive map demo, animated with D3, shows map tiles being loaded and positioned as users progressively zoom and pan. It provides a proof-of-concept for tile-based mapping using only D3, avoiding dedicated map libraries. The visualization fetches OpenStreetMap tiles from MapQuest’s tile server, addressing them by column, row, and zoom level. The animation uses D3's selection and transition methods, applying CSS 3D transforms via `matrixString` for smooth scaling, and manages a request queue for efficient image loading. The code demonstrates DOM manipulation and coordinate logic borrowed from Modest Maps, with a fallback to standard CSS transforms.
