Map Accessibility Enhancer

Use this page to create more accessible versions of my maps. This will tweak some colours and add letters to identify a few building/shop types. If you have suggests for further tweaks, please let me know.
It's quite resource intensive and may take up to 10 seconds to complete, so please save a local copy for re-use.
An up-to-date accessible copy of a map will be used if it already exists - Thanks to Siilaan for the suggestion!
