data/mods/alt_map_key/README.md
This mod replaces most of the symbols used for ASCII overmap keys. This has no effect on the large overmap screen when using overmap tiles (tiles enabled by default). It will still replace the symbols used in the overmap in your sidebar.
Land features are symbols. They're in big chunks so you don't really need a letter to tell you what each space is. For the same reason, houses are left as they were.
Buildings will be represented by the first letter of their English name. P for Pizza not Parlor. All letters are upper case.
Land feature tiles with less than full visibility are lighter shades of the full visbility tiles.
Building tiles with less than full visibility are lower case letters with the same colors of their relevant category.
Colors mark the (loose) thematic category
Blue - Service and Entertainment
Brown - Farming, Nature, and Outdoors
Cyan - Magical (This is primarily modded tiles)
Green - Food, Booze, and Restaurants
Light Blue - Vehicles, Repair, and Fuel
Light Cyan - Hardware, Tools, and Construction
Light Gray - Workplaces and Abandoned
Light Green - Housing and Residential
Light Red - Medical, Drugs, and Cybernetics
Magenta - Retail and Supplies
Pink - Science, Radiation, Monsters, and Weirdness
Red - Guns and Military
White - Tourism, Culture, Education and Public Spaces
Yellow - Government and Public Services
