Understanding map definition templates

The خطأ لوا في وحدة:Location_map على السطر 452: No value was provided for longitude. family of templates utilize any one of a set of map definitions. These are not forks but rather auxiliary pages and must have names following the pattern "Module:Location map/data/location" or "Template:Location map location", where location is the name of the area covered by the map. The template space is supported only for backward compatibility; all new map definitions should be created as modules. To create a simple map definition module using an image of a map with an إسقاط متساوي المستطيلات إسقاط مركاتور:

  1. Create a new map image and upload it to Wikimedia commons or find an existing map on the same site.
  2. Create a module named Module:Location map/data/location, copy the content below into it and substitute the appropriate values.
  3. Create a page named Module:Location map/data/location/doc and follow the instructions under #Documentation.

As an example of a map that uses an equirectangular projection, we use وحدة:Location map/data/Belgium. Please do not experiment using active templates.

return {
	name = 'Belgium',
	top = 51.8,
	bottom = 49.2,
	left = 2.2,
	right = 6.9,
	image = 'Belgium location map.svg',
	image1 = 'Belgium relief location map.jpg'
}
Parameter Description
name The name of the area covered
top The latitude of the top edge of the image using decimal degrees
bottom The latitude of the bottom edge of the image
left longitude of the left edges of the image
right longitude of the right edges of the image
image The name of the image file on Commons
image1 The name of an alternate image, usually a relief map, which can be accessed using the relief parameter.

Maps of this type work will for small to mid sized areas. وحدة:Location map/data/USA Alabama is another example of a map description that uses an equirectangular projection. Notice that the image of the country is not what most would expect.

Maps that use other projections, such as وحدة:Location map/data/USA, which uses an equidistant إسقاط الخرائط. require formulas which are used to calculate the x and y coordinates for the location mark. Understanding these formulas requires a familiarity with the subject and is currently beyond the scope of this discussion. Note that the formula for x evaluates to 0 for the left edge of the image and 100 for the right edge. Likewise, the formula for y evaluates to 0 for the top edge and 100 for the bottom edge.

Documentation

Here is an example of what a documentation page should look like:

The following parameters are taken by Module:Location map/data/doc:

Parameter Description
image An addtional image to display (other than the one the location map uses) on the right side of the documentation page. If not specified, no additional image is displayed.
projection The type of projection the location map uses. If not specified, "an [[إسقاط متساوي المستطيلات]]" is used.
name The name to display in the map's documentation. If not specified, the actual name of the location map is used.
examples A section containing examples of the location map's usage. A {{تحديد}} template is automatically placed at the end of the examples. If not specified, no examples are output.
see also Additional links to place in the "See also" section.

All information about the map will be automatically taken from the map's definition itself.
