Leaflet Tutorial 2.0

Loading UPW Point Data with Leaflet

This example visualizes point data on an interactive map using the Leaflet JavaScript library. It displays an OpenStreetMap tile layer and a Google Satellite tile layer, with a marker placed at coordinates corresponding to Lubbock, Texas, and a popup identifying the city. The map is initialized with a set view and zoom level, and both tile layers are added directly to the map instance. The code uses Leaflet’s `L.map`, `L.tileLayer`, `L.marker`, and `bindPopup` methods to load and present the geographic data.

Simple Leaflet Map

A simple interactive map centered on London demonstrates core Leaflet capabilities. The map displays OpenStreetMap tiles and includes a marker with a popup, a red circle, and a polygon, each bound to popups. Clicking anywhere on the map generates a popup showing the clicked latitude and longitude. The example uses the Leaflet JavaScript library and its `L.map`, `L.tileLayer`, `L.marker`, `L.circle`, `L.polygon`, and `L.popup` APIs to build the visualization.

Leaflet starter MM

This example demonstrates a minimal interactive map centered on coordinates [49, 50, 3], rendered with the Leaflet JavaScript library. It displays a Stamen Terrain tile layer with OpenStreetMap attribution, filling the entire viewport via a styled `#mapdiv` element. The code sets up the map instance using `L.map().setView()` and adds the tile layer with `L.tileLayer().addTo()`. The map supports standard pan and zoom interactions, relying on Leaflet’s core API rather than additional plugins or data sources.

adding geojson to leaflet map

This example demonstrates how to add multiple layers and an interactive marker to a Leaflet map. The map is initialized using the Leaflet JavaScript library and displays an OpenStreetMap tile layer alongside a Google satellite tile layer, both added to the map via the `tileLayer` and `addTo` functions. A marker is placed at the center coordinates (33.5846, -101.8456) with a popup bound to it. The data is rendered from the OpenStreetMap and Google tile servers, with the map view set using `.setView`.

Simple Leaflet Map

This example shows an interactive Leaflet map centered on Wellington, New Zealand, with a layer control that lets the user switch between two base tile layers: OpenStreetMap and OpenTopoMap. Using the Leaflet 1.6.0 JavaScript API, it defines two `L.tileLayer` instances—one pulling raster tiles from `tile.openstreetmap.org` and the other from `tile.opentopomap.org`—and adds them as selectable base layers via `L.control.layers`. The map itself is initialized with `L.map`, set to a zoom level of 14, and displays only the OSM layer initially.

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.

Full Screen Leaflet Map

This example displays an interactive map centered on Wellington, New Zealand, using Leaflet.js and OpenStreetMap tile layers. The map fills the entire browser viewport through CSS rules that set the html, body, and map container to 100% height and width. It initializes the map with a specific latitude, longitude, and zoom level, then attaches an OpenStreetMap tile layer with attribution and a maximum zoom of 18. The code relies on Leaflet’s `L.map`, `L.tileLayer`, and the `setView` method to render the full-screen interactive visualization.

Simple Leaflet Map

This example displays a simple interactive map with four settlement markers, each opening a popup with its label. The map is built with Leaflet 0.7, using an OpenStreetMap tile layer. The code initializes a map centered on the first settlement and adds markers from a hardcoded array of coordinates, demonstrating basic Leaflet map creation, tile loading, and marker popup functionality in a plain HTML page.
