From Wikipedia, the free encyclopedia
This user page is a personal shareable research tool by a non-expert in cartography, a field that is constantly changing. Good maps improve Wikipedia articles and most of the really good maps are proprietorial and do not conform to Wikimedia or Wikipedia's policies regarding Creative Commons licensing.
There is a WikiProject Map page that offers "advice, tools, links to resources, and recommended conventions. If you are serious about making maps for Wikipedia these are the experts, not the writer of this page of notes.
This user page is about making layered maps based on open source online .jpg, .psd layers using a raster graphics editor—GIMP for example—to manipulate and layer images with the ultimate goal of producing a useful customized map for specific Wikipedia articles, that do not violate any of Wikimedia Commons or Wikipedia's copyright laws.
While the base map must be open source, other non-free maps can be used to gather localized data including changes to place names—those that changed over time and the use of indigenous languages.
Basically, the process involves finding useful base maps that are already open source with clear CC licensing, then adding layers with specific labels, icons, lines, colors, and/or shapes to produce a customized map to improve a Wikipedia article without violating any of Wikimedia Commons or Wikipedia's copyright laws.
Once a map is completed, uploading it can be challenging as the fields for ensuring no protocols have been abused, can be a bit overwhelming. There are some experienced editors whose files have very complete data that proved useful, such as Hwy43 and NordNordWest.

Basic Canadian locator map
This Canadian political map was drawn and adapted from Atlas of Canada by E Pluribus Anthony on 11 March 2006. See details here

This administrative map was made on 7 February 2007 by User:Styx. It has labels in French with labels in French, was created with Inkscape, a "free and open-source vector graphics editor used to create vector images, primarily in Scalable Vector Graphics (SVG) format. Other formats can be imported and exported." The 2008 locator map resized and removed all labels from this map pour la géolocation du Canada. Inkscape coordinates are est x=80px, y=166px, height=920, width=1084. This map was improved or created by the Wikigraphists of the Graphic Lab (fr). You can propose images to clean up, improve, create or translate as well.

This basic Canadian locator map made by User:Yug in July 2008 with this description "Version recadrée et épurée de Carte administrative du Canada

In 2011 Elektryk4 used Yug's map to create a High Arctic Relocation map. Inuit families were relocated in 1953 from Inukjuak, Québec 2000 km north to Resolute Bay (left arrow) and Grise Fiord (right arrow), both Nunavut.

Basic location map of Nunavut

This Nunavut location map was made by User:Flappiefh on August 6, 2012. It uses the Lambert conformal conic projection.

This pushpin location map is used in most articles on Nunavut. It was made on September 8, 2010 by User:Algkalv and User:Dr. Blofeld based on original by User:Yug with an inset map by User:EOZyo. The two maps were put together by Ruhrfisch.

This SVG location map of Nunavut is a derivative map by NordNordWest. It uses the Lambert conformal conic projection.
Data derived from
When uploading an image to Wikimedia Commons the sources of the data used to create the image can be listed, as in this example: "Data derived from NASA SRTM, Natural Resources Canada, US Geological Survey, and Natural Earth"
An excellent example of how to cite references for "data derived" can be found in Sémhur's description here and this one by Eric Gaba and this one locator map of nothern Canada
Natural Earth
Natural Earth is a "public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software."[1]

The Workshop Project recommends .svg and .png.

It is helpful to learn how to use coordinates, pushpin map, map size, and map captions properly with lots of opportunities for error.

Learning from mistakes

I added this image in September 2018 to the article I wrote on the IPCC. It is from NASA. User:Pierre cb told me that its license should be based on the template PD-USGov-NASA {{PD-USGov-NASA and its categories should only be Category:Atmospheric rivers Category:Satellite pictures of mid-latitude storms. User:Pierre cb added that he does not want to answer any more questions.
Learning from pros
NordNordWest has some very helpful suggestions. Apparently in a map project on India, Pakistan and Bangladesh is national maps "line up correctly with the coastlines in these regions in a way not done by any current location map for subnational divisions there, so I'm assuming they are accurate boundaries". User C1MM asked NordNordWest where their data come from. C1MM said "US national imagery data is very vague, I looked and it seems you have to have some special login in order to access it. Is that how you get the data?" NNW said "Data usually used for my country maps is en:Vector Map Level Zero. But this data is outdated or even incorrect so I often grab a satellite image and update/correct it. I think that's the main difference to other map contributors: most of them don't check their free data." NNW 13:51, 30 January 2021 (UTC) C1MM asks "Ah, that makes sense. What about information about administrative boundaries such as provinces, states etc?" NNW says, "I simplified layering for India location map (no nested layers inside groups like there is now) and merged all international provinces/subdivisions in the other countries layer into a single path and reduced the document size to ~1.3 MB. Is it best if I upload this now under a different name and then some administrator can grab it and update the actual file and delete the placeholder?"

Background and river course data from authored by Shannon. Shannon's description is "Map of the drainage basin of Finlay River, a tributary of the Peace River in Northern BC.
