API:Geosearch

This page is a translated version of the page API:Geosearch and the translation is 53% complete.
Languages:

GET request to search for wiki pages near a location with geographic coordinates or page name.

This module is supported through the Extension:GeoData currently not installed on MediaWiki but Wikipedia. So, in this document, we will use the URL en.wikipedia.org in all API endpoints.

Example 3: Search for pages nearby with images

GET request

As an enhancement to Example 2, here we use the Generator module to get search results for pages near Wikimedia Foundation headquarters with images. Parameters passed along with a generator must be prefixed with a g. Note that in the query below, we've changed gs coord to ggs coord.

บันทึกเพิ่มเติม

  • This module is supported through the Extension:GeoData , currently installed on Wikimedia Commons, all Wikipedias, all Wikivoyage sites, and some other wikis. You can use Special:Version of a wiki to check if the extension is listed there.
  • In addition to using the API as to ask for a page coordinates (as explained in Example 1), here are a few more ways to obtaining them:
    • If you want your user's current location, it's available through many OS-specific APIs. Recent browsers have an opt-in navigator.geolocation object. See MDN docs.
    • If you want the user to provide coordinates, there are various services that let the user pick from a map. See w:Wikipedia:Obtaining geographic coordinates.
