## Goal

Review an area based on aerial imagery & Mapillary for:
- cycleways
- lit
- surface
- sidewalks

Choose an area: https://stm.hauke-stieler.de/project/961

## Tagging

### Cycleways

* Use `cycleway=lane` (on the road) or `cycleway=track` (separate from road) or `shared_lane` (just some paint)
* Add left/right if both sides are different, e.g. `cycleway:left=lane`, `cycleway:right=no`
* Add `cycleway:both=no` to indicate there are none
* If there are separate cyclepaths, make sure the main road has `bicycle=use_sidepath`

### Surface

* Add `surface=asphalt` or `concrete`, `dirt`, `paving_stones` `paved`/`unpaved` for the main road
* If the cycleway is different, add its `cycleway:surface` (or maybe `cycleway:left:surface`)

### Lit
Is the highway lit?

* Add `lit`=`yes` or `no`

### Sidewalks
Does the road have sidewalks?

* Add `sidewalk`=`yes`/`no`/`left`/`right`
