This example maps individual trees in a Brussels area by querying OpenStreetMap data through the Overpass API. The R script constructs an Overpass query for nodes tagged `natural=tree`, retrieves the JSON response, and uses `jsonlite` and `purrr` to extract the elements. It then converts the longitude and latitude coordinates into a simple features object with `st_as_sf`, projecting them to EPSG 4326 for spatial handling. The resulting data is ready for plotting as point geometries.

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.

Adapted the script by Yonhah: https://github.com/yonghah/esri2sf/blob/master/R/esri2sf.R

This example demonstrates how to fetch GIS feature data from an ArcGIS REST server and convert it into simple features for spatial analysis in R. It shows a workflow that queries a specified layer, retrieves object IDs, and then pulls the corresponding attributes and geometries as GeoJSON. The code relies on the `httr` package for HTTP requests, `jsonlite` for parsing JSON responses, and `sf` for handling spatial data. It also includes a helper function to generate authentication tokens when the server requires login. The implementation uses the ArcGIS REST API's `query` endpoint to request data in batches of 500 IDs, ensuring efficient retrieval of large datasets.

Gist 05f4cffac50217bd0c33a538cb013563

This example visualizes geographic routing and geocoding workflows in R, showing how spatial data can be processed and mapped. It installs and loads packages for text mining, word clouds, and interactive map viewing, including `ggplot2`, `tm`, `wordcloud`, and `RColorBrewer` for static and corpus-based visualizations. The code also integrates the `photon` and `osrm` packages via `devtools` to access geocoding and routing APIs, enabling point-and-route calculations. The visualization pipeline combines spatial operations with text analytics, demonstrating a multi-step data enrichment and mapping process.

Gist f3b3c7d224f1701a9d7f

This Shiny application lets a user upload a CSV file of XY coordinates, which are then read with the built-in `read.table` function and converted into a spatial points object using `SpatialPointsDataFrame` from the `sp` package. The app renders a basic scatterplot of these points via `plot()` and offers a download button that exports the coordinates as an ESRI Shapefile using `writeOGR` from `rgdal`, zipping the resulting files for delivery. The interface is built with `bootstrapPage` and `fileInput`, and it validates that data has been selected before plotting.

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.

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`.

Raster & Vector I

This example overlays vector street data from a TopoJSON file onto raster map tiles from OpenStreetMap. The visualization uses d3-tile to fetch and position the image tiles, while d3.geoPath renders a black mesh of road lines over them. The map is centered on Detroit using a Mercator projection configured with d3.geoMercator. Both the raster tiles and the vector streets are drawn as SVG elements, combining the two data types in a single static view. The code also loads the TopoJSON with d3.json and converts it to a mesh using the topojson library.

Convert Messy Spreadsheet of Berlin Street Names to GeoJSON

This visualization converts a messy CSV file of Berlin street names into a GeoJSON FeatureCollection. The XQuery script uses `csv:parse` and `map:merge` to clean the data, expanding abbreviations like "dr" to "doctor" and normalizing gender fields. It then calls the Mapbox Geocoding API via `http:send-request` to retrieve geometry for each street address, bounded to Berlin’s coordinates. The resulting features are assembled with `array` and output as JSON, ready for mapping.
