I am this OpenStreetMap wiki user

• https://wiki.openstreetmap.org/wiki/User:Bkil
• http://bkil.hu/

For data sources, I use the following

• fresh notes from surveys on foot or by bike via Vespucci and GPS Tracker
• mapping parties
• my personal knowledge from previous surveys or visits
• personal knowledge of locals I talk to
• personal knowledge of locals I ask to assist in a given editing session
• Mapillary
• orthophotos (Bing, FÖMI)

I prefer to add the following

Ways

• highway=path
• highway=footway in complicated cases around intersections, highway=traffic_lights
• small sections of barrier=fence when it interferes with a path

Areas

• leisure=
  • playground
  • pitch
• landuse=
  • commercial
  • industrial
  • farmland
  • grass
  • forest: very woody areas
  • village_green: mostly unmanaged, common use areas of mixed grass/woods/bushes mostly unsuitable for leisure, but still good as an optical and noise barrier and nice to look at, sometimes contains edible plants as well
• building=yes

Nodes

• natural=tree, scrub or shrub for edible plants
• tourism=viewpoint
• shop=convenience
• amenity=
  • drinking_water
  • bench
  • waste_basket
  • pub
  • restaurant
• public transport
• emergency=fire_hydrant (I omit the type for pillar)
• man_made=survey_point
• anything noteworthy and relevant that seems missing

Additional tags

• access=no for closed, private or forbidden routes
• house numbers mostly as seen on the entrance, rarely interpolated - if the corresponding building is not obvious, the gate/entrance is tagged with the house number
• for difficult routes
  • surface
  • tracktype
  • trail_visibility
• POI info
  • opening_hours
  • lunch:menu
  • contact:website
  • contact:email
  • contact:phone
  • internet_access:ssid
  • outdoor_seating
  • food=no
  • payment:*
