Editing Incubator escapee wiki:WikiProject Geographical coordinates (section)

==Tools and applications based on coordinates from Wikipedia==
Articles (and coordinates) can be found through the pages using the templates in [[:Category:Coordinates templates]]

All coordinates are available for download in [[Wikipedia:Database download|Wikipedia database dumps]]. To get the coordinates from the [[XML]] format dump of all articles (enwiki-latest-pages-articles.xml.bz2, 4 GB), the dump needs to be [[Parsing|parsed]] for pages containing coordinates in the [[#Coordinate templates (currently used instead of geo tag)|entry formats listed above]]. Most articles in Wikipedia conform to these formats and coordinates are easy to parse from the [[wikitext]] with [[regular expression]]s for simple character sequences. As all coordinates link to [[Template:Coor URL|the same PHP tool]], they may also be found from the [[SQL]] format [[:mw:Externallinks table|table of external links]] (enwiki-latest-externallinks.sql.gz, 725MB). This second method will however not include all available information about the coordinates, such as their position between the article body and the title area.

There may exist some groups of articles that generate the coordinate data dynamically and are not in any of the standard entry formats, as some editors may have wished to facilitate entry of common coordinate related information, while only keeping the output similar with the existing templates. To get all such coordinates, all the articles in the database dump need to be run through a wikitext parser (such as the [[PHP]] one in [[MediaWiki]]) to expand all the templates, and the result parsed for coordinates. Alternatively, it is also possible to download the HTML generated from all the article and expanded template content (wikipedia-en-html.tar.7z, 14 GB).

Note that mass downloading individual pages from the live Wikipedia site is strongly discouraged and [[Wikipedia:Technical FAQ#Is it possible to download the contents of Wikipedia?|may lead to discontinued access]].

=== [[NASA World Wind]] Samples ===
All examples use [[NASA World Wind]], with the Wikipedia overlay.  This is purely meant as an example of using a coordinated concept for geographical coordinates.

===View Wikipedia in Google Earth===
Project '''[[:de:Wikipedia:WikiProjekt Georeferenzierung/Wikipedia-World/en|Wikipedia-World]]''' scan 11 Dumps (ca,cs,de,en,eo,es,fi,fr,nl,pt,ru) and provides:
* dynamic Google-Earth layers in 21 languages. For instance: [http://toolserver.org/~kolossos/world-link.php?lang=en english Layer], [http://toolserver.org/~kolossos/world-link.php?lang=es español Layer]
* static Google-Earth layers in 10 language with different folders (Castles, Parks,...), Download at [http://www.webkuehn.de/hobbys/wikipedia/geokoordinaten/index_en.htm webkuehn.de]
* SQL-Data of all scanned coordinates

===Copernix.io - View and search Wikipedia Articles on a map===

Copernix.io is a geographical search engine allowing users to search places and information from Wikipedia on a map. Users can leave the search bar empty to see all pages within an area or type a query to get subject specific information.

Some useful examples can be found at:
* [http://copernix.io/about Copernix examples and about ]
The main search page is at:
* [http://copernix.io Copernix.io]

===Visualization of Wikipedia articles with Google Maps===
* [http://www.geonames.org/wikipedia.html www.geonames.org] over 800,000 Wikipedia articles in 230 languages on Google maps. The placemarks include short descriptions of the displayed items, extracted from the Wikipedia articles. Webservices for full text search and reverse geocoding of Wikipedia articles.

===WikiMiniAtlas JavaScript plugin===
[[File:WikiMiniAtlas_KML_screenshot.png|thumb|upright=1.15|WikiMiniAtlas displaying the KML data attached to the [[Bridgwater and Taunton Canal]] article (blue line) and the Coordinate points from the article (blue dots).]]
[[meta:WikiMiniAtlas|WikiMiniAtlas]] is a JavaScript to add to your [[Special:Mypage/monobook.js|monobook.js]]. It adds a draggable and zoomable (just like GoogleMaps) map to all geo-coded articles. Clickable labels with links to other geocoded articles are placed on the map to allow spatial browsing of Wikipedia. Map layers include [[:File:MiniWikiAtlas screenshot 2.png|satellite images]] (using Landsat7 data) with zoomlevels down to a resolution <100m, and [[:File:MiniWikiAtlas screenshot 3.png|daily updated]] MODIS satellite data.

WikiMiniAtlas is currently enabled on Wikipedia (by clicking on the globe ([[File:Erioll world.svg|18px| ]]) beside the coordinates).

===All geodata in SQL file format===
* Project '''[[:de:Wikipedia:WikiProjekt Georeferenzierung/Wikipedia-World/en|Wikipedia-World]]''', provides the complete database for download in [[SQL]]-file format.

=== Export multiple coordinates ===
[[tools:~para/cgi-bin/kmlexport|Kmlexport]] tool: Pages marked with multiple coordinates or categories of articles with coordinates can be exported as [[Keyhole Markup Language|KML]] (for use in Google Earth, for example). This tool and some alternatives can be found on clicking the coordinates or by applying the {{tl|GeoGroup}} template on a page.

The Kmlexport can be used directly or through Google Maps; see for example [http://maps.google.com/maps?q=http://toolserver.org/~para/cgi-bin/kmlexport?article=Colmar_Pocket Colmar Pocket] or [http://maps.google.com/maps?q=http://toolserver.org/~para/cgi-bin/kmlexport?article=Category:Capitals_in_Europe Category:Capitals in Europe]. Export from articles is real-time, export from categories is based on stored extractions (may be several weeks old).

KML may be converted in other formats, suitable as [[Point of interest|Points of Interest]] (POI) for [[Global Positioning System|GPS]] systems.

Other sources:
* [http://www.wikitude.org Wikitude] provides coordinates as KML or [[TomTom]] POI format.

====Coordinates search tool====
[[tools:~dispenser/cgi-bin/geosearch.py]] allows for regular expression searching on the GeoHack links in the external links table. This has the advantages of near real time information and powerful pattern matching. The following are some example queries created as a demonstration of the flexibility of the system.
