Diese Seite auf Deutsch: Wikipedia:WikiProjekt Georeferenzierung/Wikipedia-World

Thanks to the free availability of the collected data and thanks to the innumerable helpers who attach geo information to the articles, it is possible to describe the position of locations with the degrees of longitude and latitude in all languages by using maps. This shows the international aspects of Wikipedia.

We are looking for users that are active on the German Wikipedia and in Wikipedia in other languages in order to promote this project.

Project description

Bearbeiten

This is the international co-ordination page for the multilingual usage and analysis of the geographical data collected in the projects Georeferenzierung, en:Wikipedia:WikiProject Geographical coordinates and others.

We use the links to geohack which are in the database in the external link table, actually we use the daily updated extract on toolserver from user:dispenser. We were looking for categories in the languages pl, ja, it, zh, sv, etc. that include all geotags (see interwiki links in the category Kategorie:Vorlage:mit Koordinate) in order to be able to include more languages.

Via the interwiki links all language variants are analyzed and recorded in a common database. In order to achieve this, a co-ordination on the used geographical coordinates templates is necessary.

At the time being, there are the following applications that are all based on the central PostGIS-database on the Toolserver (ptolemy). The maps can also be accessed via geohack:

Simple maps

Bearbeiten

With the help of simple HTML and CSS code simple maps without background can be comfortably produced using the following links for a limited number of languages or by modifying the URL: For example use http://toolserver.org/~kolossos/wp-world/umkreis.php?la=af&submit=v&lon=13&lat=52&rang=1462.5&map=2&limit=80 for Afrikaans.

English, German, Spanish, French, Italian, Japanese, Dutch, Polish, Portuguese, Russian, Swedish. Turkish, Chinese, Icelandic, Catalan, ... >270 languages.

The map view is also available via a world map, in which you have to click only on the desired region.

Dynamic layer

Bearbeiten

The data used for this are in a database and are filtered according to the articles length and the focus of the user. The corresponding articles are then put over the map using a layer. The database access occurs after a one second stand still of the user's viewpoint.

A click on one of the symbols and a further click on the Wikipedia link enables the user to comfortably access and read the wikipedia articles.

You can select the desired language using the links below or via the URL http://toolserver.org/~kolossos/world-link.php?long=13.3783&lat=52.5163&lang=LANGUAGE replacing LANGUAGE with the ISO code of the requested language.

English,

Czech, Danish, Dutch, Esperanto, Finnish, French, German, Italian, Japanese, Norwegian, Polish, Portuguese, Russian, Slovak, Spanish, Swedish. Turkish, Chinese, Icelandic, Catalan, ... >270 languages.

Expert mode
Bearbeiten

This view can be configured in multiple ways. If you click on the networklink in Google Earth with the right mouse button in order to edit the link, the URL (http://toolserver.org/~kolossos/geoworld/marks.php?LANG=de) is displayed, which can be appended with additional parameters:

thumbs
URL&thumbs=yes So you can see little thumbnail pictures. We are using the first jpeg-image of each article, see Screenshot, so we use over 37.000 images. Direct Link
style
URL&style=world_cultur shows only the world cultural heritage sites. A full list of all styles can be found in the file info.php listed above. Because objects are only assigned to one object type, this is only reliable in a limited way.
photo
URL&photo=no shows only articles, that do not feature an image. Ideal to plan a photosafari in a certain region. Direct Link
URL&photo=yes shows only articles, that have already an image. However, this also includes images like COAs or location maps, etc..
source
URL&source=de shows only sites, that come from the German Wikipedia. All input languages are supported.
notsource
URL&notregion=de does the contrary of the parameter "source".

World map with a representation of the concentration of wikipoints

Bearbeiten
 
Image: concentration of entries in logarithmic scale. Click on it to see an up-to-date image.

The image shown above can be generated online from the database. There are three parameters, which can be passed with the URL:

    • Parameter "so" for "source" limits the display of articles orginating from a certain Wikipedia language source. Only these coordinates are shown that have not already been read from another language.
    • Parameter "la" uses all available coordinates of a language.
    • Parameter "fa" is a zoom factor, which can be 0.5, 1, 2, 4 or 8. Zoom fa=1 equals one pixel per degree. The time need for the generation of the image increases with the increase of the zoom factor.

Example: http://toolserver.org/~kolossos/wp-world/imageworld-art-new.php?so=en&fa=2 shows the articles from the english Wikipedia.

For the AR app Layar a content layer with the data of this project is available. Content layer is called WikipediaWorld and developed by user:Arch2all. Layar can be used on Android smartphones and iPhone 3GS and is freely available in the Android market/App store.

To-do list

Bearbeiten
  1. Merging this data with data of OpenStreetmap (http://wiki.openstreetmap.org/wiki/Key:wikipedia) in an half-automatic way. Automatically isn't possible because we want to connect our point objects with OSM points, lines and areas. Benefit for both projects because OSM could e.g. use Wikipedia Interwikilinks and Wikipedia could use the types of OSM and the exact position an geographical representation.
  2. Using bots like fr:user:Geobot to copy geocoordinates to other languages
  3. more and better icons in the map using styles and categories
  4. testing mapnik-rendering with click areas
  5. further development of the CSV service
