PZH wms sld test

This example demonstrates how a Provincie Zuid-Holland Web Map Service (WMS) can style distinct layers for preferred solar-energy locations, including suitable building blocks, parking lots, former and active landfills, and agricultural sites. The Styled Layer Descriptor (SLD) defines polygon fills in a categorical color scheme for each land-use type, while points representing agricultural businesses render as circles of varying colors based on policy attributes. The code uses the OGC SLD 1.0.0 XML schema with GeoServer-compatible filters and symbolizers, applying rules through `sld:PolygonSymbolizer` and `sld:PointSymbolizer` elements to control the map’s appearance.

A basic map with MapboxGL.js

This example displays an interactive map centered on Amsterdam, featuring a tilted and rotated view of the city with MapboxGL.js. The map uses the Mapbox streets style, with zoom, pitch, and bearing set to create a perspective view. The code loads the mapbox-gl.js library and its associated CSS, then initializes a `mapboxgl.Map` instance on a container div, adding a navigation control. It relies on a hardcoded Mapbox access token to fetch tile data from the Mapbox service, showing how to embed a basic map with custom camera settings.

A basic map with MapboxGL.js

This example shows a basic interactive map of the Netherlands, displaying earthquake data as colored circles and extruded 3D buffers. The map uses MapboxGL.js v0.44.0 to render vector tiles from the PDOK topotiles service and GeoJSON point and buffer data from GitHub. Circle radius and fill-extrusion heights are interpolated based on zoom level, while colors are assigned categorically by earthquake type. The code defines a full Mapbox style object inline, including sources, layers, and paint properties.

This visualization displays earthquake data for the Netherlands in June 2017, plotted as circles on an SVG canvas using D3 v4. The code includes two commented-out approaches: one mapping quake locations by latitude and longitude with `d3.scaleLinear` and `d3.scaleSqrt` for magnitude, and another plotting events over time using `d3.scaleTime` for date, linear scaling for magnitude, and `d3.scaleOrdinal` with `d3.schemeCategory10` for quake type. The data is loaded from a tab-separated text file via `d3.tsv`, with parsing and formatting handled manually. Currently, the render function runs but displays nothing because both rendering paths are commented out.

A basic map with MapboxGL.js

This basic map example uses MapboxGL.js to visualize earthquake data in the Netherlands. It displays points colored categorically by quake type (induced vs. tectonic) with extruded buffer heights based on depth, overlaid on a base map of provinces and urban areas from the PDOK topotiles service. The map initializes with specific zoom, pitch, and bearing settings. An interactive hover effect on provinces displays the region’s name in a side panel, implemented through map event listeners and a dynamic layer filter. Depth labels appear at higher zoom levels.

A basic map with MapboxGL.js

A point and extrusion map of earthquakes in the Netherlands, styled with a custom MapboxGL style. It layers Dutch administrative boundaries and urban areas from PDOK vector tiles, then plots each earthquake as a circle colored by type (induced or tectonic) and radius scaled by zoom. A 3D fill-extrusion of each quake’s buffer visualizes depth, with labels showing recorded depth at higher zoom levels. The map runs in MapboxGL.js v0.44 using a JSON style with categorical color stops and zoom-dependent height interpolation.

A basic map with MapboxGL.js

This interactive web map visualizes earthquake locations in the Netherlands, distinguishing between induced and tectonic events through color-coded circles whose size scales with zoom level. Built with MapboxGL.js, the map overlays GeoJSON point data onto vector tiles from PDOK, incorporating Dutch administrative boundaries, urban areas, and place labels from the same source. The custom style file defines categorical circle colors, zoom-dependent radius stops, and three label priority layers, while the HTML page sets initial camera position, pitch, and bearing.

A basic map with MapboxGL.js

This example visualizes earthquake data in the Netherlands on a Mapbox GL JS map. It renders point locations colored by earthquake type, with extruded buffers showing depth through varying heights, and labels displaying depth values. The style uses a vector tile source from PDOK for administrative boundaries and urban areas, while earthquake data comes from GeoJSON files hosted on GitHub. The map starts with a tilted perspective, and includes navigation controls for zoom and rotation.
