I don’t take the effort to map surface quality because it is not used for anything.
Just so you know. It can be invaluable to disabled people trying to get around.
Myself. With visual impairment. Where my vision can change drematically from day to day.
Knowing the surface quality can let me know if a route can be done with just a cane. Or if on a bad day I am better off just going a longer route. Or waiting till a better day.
Please remember what seems unimportant to you. Can be absolutely essential to others less able to answer the questions then yourself.
