Notes

[edit]
Current translation effort (fr-en)

Some map-related tutorials in the process of translation from French into English at :

Drawing tutorials

[edit]

French team have the following set of tutorials: French graphic tutorials. Translations welcome !

Labeling tutorials

[edit]

How to do labeling with multiple translations, a mix of ltr and rtl languages and/or additional symbols, see here:

Multiple translations within one SVG file

[edit]

See:

More examples:

Multiple translations with symbols

[edit]
Example for Symbols and Labels

It becomes more complex, if you have not only a label but additionally one ore more symbols identifying an object.

You can see in an example on the right how to do this in a clear, concise and comprehensible manner:

Define the symbols in the <defs> section, insert them into the map using a <use> statement, and then place the label (in multiple languages) relative (sic!) to the symbol with a second <use> statement.

Multiple translations with a mix of ltr and rtl languages

Draft of a sample file (english)

It looks more authentic when the icon is placed before the text within a legend. This is a challenge, if you have to handle a mixture of left-to-right and right-to-left languages. It is a matter of using an additional switch construction to shift the icons to either the left or right position. This results in nested switch statements that are quite complex.

You can see in an example on the right how to do this in a clear, concise and comprehensible manner:

Define the symbols and the switches with the translations of the labels in the <defs> section. Then group each of them in a <g> element. Then insert them both into the legends section in another switch construction. Do this twice, once for 'rtl' languages, then for all others ('ltr' languages). Each time with an adjusted y="4711" parameter, so that the icons are placed on the right-hand side of the legend one time and on the left-hand side the other time.

See also a more complex example.

Text with Shadow

[edit]
Example for Text with Shadow

If there is a lot of information in maps or infographics, the background becomes very cluttered, which impairs the legibility of the labelling. This can be remedied by adding a border or shadow to the labelling, which increases the contrast with the background. The example on the right shows how this can be achieved.

Map tutorials

[edit]

There is a list of existing map tutorials; more are welcome. French users have provided some, and translations into English would be welcome.

The best places to obtain SVG map backgrounds are listed in SVG maps, particularly Location_maps (2008 standard) and their sub-pages. The Map conventions and toolbox also provide six helpful conventions, some strongly supported by specific teams. The tutorials below follow the training of a hypothetical new map maker: the deeper you go, the more complexity and beauty you find.

Demonstration of how an SVG map is built layer by layer:
1.Valley; 2.Plain; 3.Hill; 4.Rivers; 5.Troops; 6.Moves; 7.Text; 8.Locator map; 9.Legend.
