This example shows how to retrieve all Dutch address objects (verblijfsobjecten) in the town of Zuidhorn from the BAG Web Feature Service (WFS) using paging to handle large result sets. The code first queries the server’s maximum page size via GetCapabilities, then counts matching features, and finally fetches them page by page using `startindex` while sorting by identifier. It uses the `httr`, `xml2`, and `sf` R packages to parse the WFS responses and convert the resulting GeoJSON into simple features, which are then mapped with the `tmap` package. The data source is the national georegister’s BAG WFS endpoint.

Parse WFS response in R

This example demonstrates how to inspect a WFS service’s capabilities and identify its supported output formats and available feature types, along with the server’s maximum result limit. The R script uses the `XML` package to parse the `GetCapabilities` response from the Dutch national georegister’s CBS boundary service, applying XPath queries to extract `ows:Value` texts and `wfs:Name` entries. It also reads the `CountDefault` constraint to determine the per-request cap. The output shows the parsed metadata as character and integer vectors, revealing the service’s configuration without fetching any actual geographic data.

ArcGIS Online hosted feature service in lezen in R

This example demonstrates how to read and visualize the Dutch national heritage register (Rijksmonumenten) from an ArcGIS Online hosted feature service. It shows the full workflow of querying the service's metadata, counting features, and paginating through all 64,020 records, then maps them with `tmap` and `sf`. The code uses the `httr` and `jsonlite` packages to construct URL requests and parse JSON, while `sf::st_read()` reads the GeoJSON response. It explicitly checks pagination support via the service’s `advancedQueryCapabilities` and explains an anomaly where the initial page returns more records than `maxRecordCount` suggests. The final map is rendered with `qtm()`, and summary statistics (min/max OBJECTID) are computed via the service’s `outStatistics` parameter.

sf only supports request paging for ESRI’s hosted feature service, not for WFS

This example compares pagination behavior in R’s `sf` package for two web service types. It demonstrates that while `sf` automatically pages through ESRI hosted feature services, fetching all records, it does not for WFS endpoints, where only the first batch of records is retrieved despite the presence of a `next` URL in the response. The analysis uses live API queries to BAG WFS and ArcGIS services, with code in R and visualizations rendered via R Markdown. The title and author metadata are shown at the top.

R-script voor het downloaden en georefereren van een OpenStreetMap tile

This R script downloads a single OpenStreetMap tile centered on the Martinitoren in Groningen and georeferences it by generating a World file. It first converts latitude and longitude coordinates to tile coordinates using the slippy map tilenames algorithm, then fetches the PNG from the `tile.openstreetmap.org` server. The script calculates the tile’s bounding box from the zoom level and writes a six-line `.pgw` file with pixel-to-world transformation parameters, enabling the image to be overlaid with geographic data in GIS software. The code uses base R functions like `download.file`, `paste0`, and `writeLines` without external libraries.

Oefenen met scale

This example demonstrates how to load and display geographic boundary data from a Web Feature Service (WFS) endpoint using D3.js. It shows a map of Dutch arrondissementsgebieden (judicial districts) for 2019, projected with a Mercator projection. The code uses `d3.json` to fetch GeoJSON from the national georegister WFS, then renders it as SVG paths via `d3.geo.path` with a `d3.geo.mercator` projection. A simple alert greets viewers before the visualization loads, and the SVG canvas is sized to 960 by 500 pixels.

R-script voor het downloaden en converteren van een JSON-bestand met locaties van jachthavens converteren naar shape-bestand

This example demonstrates how to download JSON data containing marina locations from a Dutch tourism website and convert it into a shapefile. The script shows the process of fetching data via an HTTP POST request with a custom header, parsing the JSON response, extracting attributes like address and contact details from nested HTML, and then transforming geographic coordinates from WGS84 to the Dutch RD coordinate system using the `sp` and `rgdal` packages. It uses `httr` for the API request, `jsonlite` for JSON parsing, and `XML` for handling HTML content within the JSON. The final shapefile is written with `writeOGR`.

R-script dat aan de hand van de gegevens uit het objectenportaal van de provincie Groningen, de BAG en de Zonneatlas bepaald welke panden van de provincie Groningen wel/niet geschikt zijn voor het opwekken van zonne-energie

This R Markdown analysis determines which buildings in the province of Groningen are suitable for solar energy generation, based on open data from the provincial object portal, the BAG (Basisregistratie Adressen en Gebouwen), and the Zonatlas. It shows the workflow from downloading building and address data via WFS APIs to converting address objects into building polygons using the `httr`, `sp`, and `rgdal` packages. The script also integrates municipal boundaries to apply the correct Zonatlas layer, producing a reproducible geospatial assessment.

met wfs en geojson als output formaat

This example shows how to load and display GeoJSON data that has been retrieved from a WFS (Web Feature Service) and converted to TopoJSON format. The map renders the Dutch municipal boundaries as SVG paths using D3 v4. The data pipeline is notable: GeoJSON in EPSG:4326 is fetched from a WFS, the winding order of the polygons is reversed in FME, and the result is written to TopoJSON. The visualization displays the topology-encoded arcs, demonstrating the boundary polygons of Dutch municipalities with a minimal, functional style typical of D3 examples.
