This example shows a Google Map of Newark, New Jersey, with a historical ground overlay—a 1922 map image sourced from the University of Texas libraries—that can be toggled on and off. Two UI buttons trigger the `removeOverlay()` and `addOverlay()` functions, which call `historicalOverlay.setMap(null)` and `historicalOverlay.setMap(map)` respectively. The map is initialized with the Google Maps JavaScript API, and the overlay is defined by explicit latitude and longitude bounds.

04: Custom Map Controls

This example demonstrates a map with two toggleable layers—hexbins and crash points—overlaid on a Mapbox GL base map. The hexbins are generated from a GeoJSON dataset of NYC crashes using Turf.js to create a hex grid and count incidents per cell, colored with a Jenks natural breaks classification. Custom UI buttons let users toggle each layer on and off, with active states highlighted. The code also shows how to filter invalid geometries and style layers dynamically.

Mapbox GL example of different zones with on off buttons

This Mapbox GL example displays multiple geographic zones around Houston, Texas, with interactive toggle buttons for layering school locations, school zones, zip code areas, and county boundaries on a single map. Using the Mapbox GL JavaScript API, the visualization loads vector tile sources from the author’s Mapbox account and toggles layer visibility through HTML menu links with CSS styling. The map also includes a popup and overlay for additional information, though these features are only partially implemented in the provided code.

Gist cd3b399ded90abed9e03930563398518

This example displays a Mapbox GL JS map centered on Houston, Texas, at zoom level 10, with a set of airfield-style symbol markers plotted over a custom vector tile source. The visualization uses `map.addSource` to load a hosted vector tileset containing school location data and `map.addLayer` to render those points as icons via the `symbol` layer type. A collapsible overlay panel and a menu for switching map views are included, though the menu’s active state and overlay content are not populated in the provided code. The map style is a custom Mapbox style URL.

Google Maps + D3

This example overlays a custom D3 visualization on an interactive Google Map, plotting California weather station data as brown circles with labeled markers. The map displays terrain tiles from the Google Maps API, while the overlay is drawn using D3’s `d3.json` to load station coordinates and attributes. Each marker is rendered as a separate inline SVG element, positioned via the Google Maps projection’s `fromLatLngToDivPixel` method when the overlay is added. The code combines the Google Maps JavaScript API with D3’s selection and data-binding capabilities to synchronize the dynamic overlay with the map’s pan and zoom.

Simple Leaflet Map

This example shows a Leaflet map centered on Wellington, New Zealand, with selectable base layers and an overlay of local landmarks. It uses Leaflet’s `L.map`, `L.tileLayer`, and `L.control.layers` to switch between OpenStreetMap and Thunderforest landscape tiles. An `L.LayerGroup` contains four markers with popups and a polyline connecting the points, which can be toggled as an overlay. The code also uses `L.marker` and `L.polyline` to add geographic features to the map.

A simple map

This example shows a basic interactive map centered on a view of New York City, with the Mapbox streets basemap displayed at zoom level 9. The map is rendered in a full-screen HTML page using the Mapbox.js library, which initializes the map object via `L.mapbox.map` and sets the geographic coordinates and zoom level with `.setView`. The map uses a public access token from the author Jn1532 to load the tiles.

Lots of points in Mapbox Basemap - Test

This example demonstrates a Mapbox GL map with a tilted and rotated view centered on the New York City area. It shows how the map’s basemap style can be dynamically switched via a custom control panel overlaid on the map. The page uses the Mapbox GL JS API to initialize the map with a specific style, pitch, bearing, and zoom level, while the `switchLayer` function updates the map’s style based on user input. A transparent title box with radio buttons allows selection among different style layers, and the Navigation control adds zoom and rotation controls.

Mapbox 1.X Reference Examples

This example showcases a collection of Mapbox GL JS code snippets, extracted from official documentation at version 1.12.0, demonstrating various interactive mapping techniques. It features an animated image overlay on a map, using the Mapbox GL JS API to handle tile rendering and camera controls. The snippets illustrate how to integrate custom vector tiles and geospatial data, with code for styling layers and managing user interactions. The project serves as a reference for common mapping tasks, such as adding markers, drawing polygons, and animating data over time.
