PDOK: dutch webservice

• Providing location services as a Web API:
  • Search: “address”,return: coordinates, regional administrative info (>30).
  • deduplicating addresses (“town road” vs “town street” vs “town alley”)
• Providing geo tile layers.
  • restricts topographic details to NL.
  • style: “gray”, “brt”, “aerial” and “pastel”

• geocodes a list of addresses (location + 30 regional properties)
• modelled after ggmap::geocode same argument names.

• one location per address (with highest score).

  • for extra options use nl_free

• returns a sf object:

  • However: is POINT/ centroid, not the complete geometry.

• type: returned object should be: “address”, “street”, “postcode”, “town”, “municipality”, “neighborhood”, “province” etc.

wrap each pdok service faithfully:

• same argument names as the web service
• all options available

However:

• return value is also faithful, but complex, so more difficult to use

Utility function to provide pdok tiles in leaflet: maps for Dutch regions:

• brt: background (similar to OSM)
• gray: grayed-out background
• pastel: pastel tone background
• aerial: aerial/satelite background

library(leaflet)
leaflet() %>% 
  addPdokTiles() %>% 
 # do your mapping thing

library(nlgeocoder)
library(leaflet)
r <- nl_geocode("Henri Faasdreef 312") # uRos 2018 Conference!
leaflet() %>% addPdokTiles("gray") %>% 
  addMarkers(data = r, popup = "uRos2018!")
