Step 1: Research the map data

2. Prepare the data for the upload

You can prepare the data in a spreadsheet. You need to process some of your original data to suit Wikimedia.

• title, description Wrap title and description in a language template {{en|Your title goes here}}
• wikidata title If the map exists as a Wikidata item (not usually likely) find the corresponding id. wikidata title = Q12345.
• author Wrap author in the Creator template. author = {{Creator:Name Surname}}. You can use this tool - Creator from Wikidata - to make the template from data about a known author in Wikidata.
• date, map date, print date Use ISO dates for dates. If you need more complex dates, use template {{other date}}. map date = {{other date|-|1890|1895}} for 1890–1895.
• source The source can be a link to the original file and/or the description page. For an institution, you might want to prepare a complex partnership template (ask a wikimedian), or just provide a credit line. For a scan from a book, provide a link (preferably an ISBN) and page number. source = {{Kartverket}} is a partnership template that sets relevant categories, displays the organization logo and a link to the organization.
• permission Licenses are declared using license templates. Here are some common license tags to be used:
  • {{PD-old-70}} to use for works whose creator died more than 70 years ago. Does not state the US copyright status
  • {{PD-old-70-1923}} or {{PD-old-70-1996}} to clarify the US copyright status
  • {{Licensed-PD-Art|PD-old-70|Cc-by-sa-4.0}} A public domain work, where the image is licensed openly. WMF does not recognize the need for licensing a faithful reproduction, but it may be handy in some jurisdictions.
  • {{PD-USGov}} if the map was prepared by an on-duty officer or employee of the United States Federal Government
  • {{Cc-zero}}, {{Cc-by-4.0}} or {{Cc-by-sa-4.0}} To license openly an otherwise copyright protected work
  • Maps are not always artistic creations. In those cases they will not have copyright protection.
• location For the location the map depicts, whenever possible link to data about the location at the time of the map. You can use one or more links to Wikidata items like location = [[d:Q13972|Tartu]]
• scale Map scale is declared with one number scale = 3000 refers to map scale 1:3 000
• latitude, longitude Latitude and longitude are defined with one, two or four coordinate values. The values are separated by ""/"":
  • 4 values: Latitude and longitude of four corners of the map. Corners have to be in the counter-clockwise order starting with lower left corner, so they are in lower left, lower right, upper right and upper left corner order.
  • 2 values: Latitude and longitude of each edge of the map. Parameter ""latitude"" will store South/North latitudes of lower/upper edge and parameter ""longitude"" will store West/East longitudes of left/right edge latitude=59.8918753/60.0069685 longitude=23.3099012/23.5377848
  • 1 value: Latitude and longitude of map center.
• warper status The value indicates if the map has been georeferenced in the Wikimaps Warper. Any non-empty value will create a link to the map in the Wikimaps Warper. Value 'help' is used to explicitly create a visible button. warper status = help
• set If several maps belong to the same series, set or atlas, they can be grouped in a category by writing the name of the category in plain text. set = Senate Atlas
• institution For the Institution, create an {{Institution}} template. institution = {{Institution:National Archives of Finland}}
• Include the link to the media file.
