This page describes how to make various types of derivative maps from maps I have uploaded.

Locator maps

The blank maps have been designed specifically for potential conversion to locator maps highlighting one, or several, of the sub-divisions. The paths in the SVG files are all named after the region they describe. I may eventually, do a bulk upload of the full set of ~20,000 locator maps, but I've got enough on my plate at the moment without that project :)

To create a locator map yourself, all that is needed is a text editor. A program that can display SVGs, such as Firefox, is also helpful to verify the file.

The following are step-by-step instructions for converting File:East Riding of Yorkshire UK parish map (blank).svg to File:Anlaby with Anlaby Common UK parish locator map.svg

1. Download the blank map and open in your text editor
2. Find the path with id="Anlaby with Anlaby Common"
3. Change the style of this path from style="fill:#fefee9;.... to style="fill:#d40000;...
4. Save the file and upload to Commons. File:<place> UK <unit type> locator map.svg is suggested. If this is ambiguous, add county/district disambiguation as per Wikipedia (without commas).

Note there a few caveats:

• When there are multiple areas with the same name, these are disambiguated using district-level info.
• If there is an ambiguous name within the same district, the id should correspond to how they are disambiguated on en.wikipedia.
• If a unit, such as a parish, has a detached region, this may have its own path which will include the name and (DET). Both should be highlighted.
• In the case of the parish maps, unparished areas and land common to multiple parishes are also included. The id for each of these should be obvious - eg "Kingston upon Hull".

If a path does not match the correct region, please let me know immediately.
