Do people prefer for pavements to be mapped or not when they do not impact navigation?
The vast majority of the UK urban maps I have looked at include all pavements. The notable exception to this was the WOC maps that excluded them.
The ISSOM specification has the following to say on the issue
"A step or an edge of a paved area. Steps of a stairway shall be represented in a
generalized manner. Edges within paved areas are generally not represented,
unless they serve navigation. The thickness of edge of paved areas shall be
enlarged to 0.14 mm in non-urban areas to improve legibility. The thickness of
step lines shall always be 0.07 mm."
