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.

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 being the production of 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.

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

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

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?"

"This view is featuring the southeastern Mediterranean and the borders of the region between Egypt, Sinai Peninsula and Israel. In 2003 On February 1, 2003, the seven crew members of the Space Shuttle Columbia STS-107 were lost over North Texas. An STS-107 crew member on board the Space Shuttle Columbia took this picture. The roll of unprocessed film was later discovered by searchers in the are from the Space Ship debris.
