Maps are an important part of any encyclopedia. They are useful in presenting key facts within a geographical context and enabling a descriptive overview of a complex concept to be accessed easily and quickly. WikiProject Maps encourages the creation of free maps and their upload on Wikimedia Commons. On the project's pages can be found advice, tools, links to resources and map conventions.

The project suggests some web-friendly map conventions, which may help to make maps more readable. The suggested conventions are free for graphists to adapt to their specific needs. Graphists who are unsure of an appropriate style, colour, or style of labelling, may find these suggestions helpful.

Scope[edit]

The aim of WikiProject Maps is to improve the quality of maps across the Wikimedia Foundation.

  • The Map conventions page provides advice for creating and improving maps.
  • The Map workshop page can be used to add your map requests and your sources. A graphist will create the requested map. The page is forum-based, to enable cross-teaching conversations to take place.
  • The Resources page provides advice to both beginners (in the form of tutorials) and experienced map-makers.

Please feel free to ask questions on our talk page.

Recommended conventions[edit]

Citing sources[edit]

As maps can be politically charged, it is important to cite your sources and/or your methodology when editing or creating any map. This is particularly true for historical maps.

Exemplars[edit]

Map styles is a subject of on-going discussion at Wikipedia talk:WikiProject Maps. Please join in the conversation there. For general use, the following is a gallery of maps that have been approved by Wikiproject Maps as exemplars:

File formats to use[edit]

Demonstration of how to create a map using layers: 1.Valley ; 2.Plain ; 3.Hills ; 4.Rivers ; 5.Troops ; 6.Moves ; 7.Text ; 8.Thumbnail map ; 9.Legend.

The use of JPEG is discouraged, since it is a lossy compression format and so will result in a blurry map or diagram. The quality of GIF images is better than JPEG. GIF images allow for the creation of animations.

PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours. As a pixel based image, it is more difficult than an SVG image to edit. Some uploaders prefer to work with SVG and then upload a PNG version.

SVG is vector graphics format, which has three main advantages:

  • Images can be scaled without data loss, which allows large-sized and very high quality maps to be made;
  • It is a text-based XML language and so can be edited and shared quickly and easily.
  • It is a precisely-coded language which can be converted by script or CSS.

When drawing an SVG map, please name any objects, groups and layers you create, so as to assist anyone who wants to correct the map, look at how the map is set up, or learn how to make an image of their own. SVG image support has been retained as a Wikimedia Meta-wiki for historical interest.

Coordinate-referenced map templates[edit]

The process of supplying freely licensed maps for direct use in Wikipedia articles is important to make the articles complete, especially for offline versions. A complementary effort, however, is adding latitude and longitude coordinates to articles about geographically fixed entities. This enables readers to click through to find maps of the surrounding area on external web sites like Google Maps. to be automatically plotted on maps.

To learn how to add geographic coordinates to a page using templates, please see Wikipedia:WikiProject Geographical coordinates.

To paste a location map with a dot (using the city of Madrid as an example), copy and paste the following code:

{{Location map|Spain|label=Madrid|mark=Green_pog.svg
|lat=40.5|long=-3.7|width=230|float=center}}

This is the result:

Madrid is located in Spain
Madrid
Madrid
Madrid (Spain)

To paste multiple dots on one location map, use Template:Location map many or Template:Location map+. For instruction on creating a map template, see Template:Location map/Creating a new map template.
