I'm using osm data to perform routes calculations with OTP. During one of my tests it fails to find a walking route. Looking at the osm data with the editor I get an idea of way why this could happen, but I would like confirmation and guidance to fix it if needed. The area is: https://www.openstreetmap.org/edit#map=21/40.53559/-3.64148 There one can see from left to rigth> An urban street 'Avenida de la industria' with a crossing That crossing leads to an area tagged as garden, but its actually paved That area limits with a main road which also has a crossing This leads to a small unmapped paved area (can be see in the bing layer) Then the other direction of the main road also with a crossing. The main road then connects to a roundabout which also connects to urban streets. Do a garden is considered walkable? Or is it needed to connect thoose crossings and urban roads with a footpath? Which is the recommended way to map this?
