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.

Vector Tiles

This interactive map displays road networks from Mapzen vector tiles, rendered as SVG paths over OpenStreetMap basemap tiles. The visualization uses d3-tile to manage tile loading and d3.zoom for panning and scaling, with vector data fetched from Mapzen’s tile server. Roads are styled by class (highway, minor_road, rail) and sorted by sort_key for correct layering. The projection updates dynamically with zoom, and hovering shows coordinates using d3.geoMercator inversion.

Vector Tiles

This example displays a static vector-tile map of San Francisco’s roads, with major highways, minor roads, and rail lines rendered as stylized SVG strokes. Using D3 v3, it loads Mapzen’s OpenStreetMap “roads” tiles via `d3.json`, sorts features by `sort_key`, and draws each path with `d3.geo.path` and a Mercator projection. A custom `d3.geo.tile` helper computes the visible tile range and scale, while CSS classes like `.highway` and `.rail` assign distinct colors and widths.

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.

Vector Tiles

This example displays a static map of San Francisco’s roads, styled by road type, without panning or zooming. It uses Mapzen vector tiles served as GeoJSON, with the D3.js v3 library and a custom `d3.geo.tile` helper to compute tile coordinates. The SVG paths are rendered via `d3.geo.path` with a Mercator projection, and the code fetches tile data asynchronously using `d3.json`. Road classes like highways and rails are distinguished by CSS classes. Data comes from OpenStreetMap through Mapzen’s vector tile API.

Zoomable Map Tiles

This interactive map shows a zoomable view of OpenStreetMap tiles that smoothly pans and zooms across geographic regions. It uses the `d3.geo.tile` plugin to calculate which 256x256 tile images are visible in the viewport based on current scale and translate values, while `d3.behavior.zoom` handles user panning and zooming interactions. The tiles are rendered as `img` elements positioned absolutely, and a `d3.geo.mercator` projection inverts mouse coordinates to display the latitude and longitude at the cursor.

Raster & Vector II

A map of the United States uses a red outline to show state boundaries over OpenStreetMap raster tiles. The code combines d3-tile for tile loading, d3.geoMercator and d3.geoPath for reprojecting TopoJSON vectors, and d3-zoom for pan and zoom. On each interaction, the tile set and vector geometry are recomputed rather than relying on a transform, with tiles rendered as SVG images.

Raster & Vector I

This example displays geographic vector boundaries overlaid on a raster map of Detroit. Using d3-tile to fetch and position OpenStreetMap image tiles, it renders them as a base layer within an SVG canvas. The d3.geoPath and d3.geoMercator projections draw a TopoJSON mesh of Detroit’s streets on top, creating a composite view of vector data and raster imagery.

Raster & Vector III

This example shows how vector geographic features (U.S. counties) can be overlaid on raster map tiles from OpenStreetMap, with both layers staying aligned during pan and zoom interactions. The vector layer is rendered as a single SVG path using `d3.geoPath` and a `d3.geoMercator` projection, while raster tiles are fetched and positioned via `d3.tile` and `d3-zoom`. Instead of reprojecting, the code updates the SVG transform and stroke-width for efficiency, using `d3.zoomIdentity` and the `on("zoom")` event.
