Details

Make a request to the spesific WFS API. The base url is https://kartta.hsy.fi/geoserver/wfs to which other components defined by the arguments are appended.

This is a low-level function intended to be used by other higher level functions in the package.

Note that GET requests are used using `httpcache` meaning that requests are cached. If you want clear cache, use [httpcache::clearCache()]. To turn the cache off completely, use [httpcache::cacheOff()]

Examples

  wfs_api(base.url = "https://kartta.hsy.fi/geoserver/wfs",

                list(request = "getFeature", 
                     layer = "tilastointialueet:kunta4500k_2017")))
