Mapping rules

in case of a dispute, I will use following mapping rules:

30-Zone "highway"="residential" "maxspeed"="30" "source:maxspeed"="DE:zone30"
Hausdurchfahrt "tunnel=building_passage"
parkplatz Scheibe "parking:condition=disk" "stay:120" "condition:time_interval=Mo-Fr 09:00-13:00,15:00-19:00; Sa 08:00-13:00" THIS IS NOW QUESTIONABLE
parkplatz Schein "parking:condition=ticket" "fee=interval" "condition:time_interval=Mo-Fr 09:00-13:00,15:00-18:00"
Einbahn/Rad frei "oneway=yes" "oneway:bicycle=no" "cycleway=opposite"
Kirche "name=St. Remigius" "building=church" "amenity=place_of_worship" "religion=christian" "denomination=roman_catholic" "service_times=Su 11:00; Tu 9:00; We 15:00" "start_date=1450" "website=http://www.st-remigius-viersen.de"
Denkmalschutzliste "historic=heritage" "heritage=8" "heritage:ref=371" "heritage:operator=UntereDenkmalbehörde" "heritage:website=https://www.viersen.de/C125704A0030C552/html/51D55665050A2786C1257456003008B0?openDocument"

Landuse / Natural / Landcover

WORST CASE, found in Wikipedia .. do not do this!

Area Tag Remark
Dauergrünland landuse=meadow
Ackerbauflächen landuse=farmland
Baumplantage/Weinberg landuse=orchard/vineyard
Grünflaeche in der Stadt landuse=grass zumindest einmal im Jahr gemäht
Grünflaeche in der Stadt natural=scrub verbuscht, nie gemäht
xx xx

recreation_ground gibt es bei uns nicht! Damit sind keine Hundewiesen gemeint!! Bei uns wird das entweder ein Park oder ein pitch. Bestenfalls als Aussenfläche um Sportstätten (Hoher Busch).

my personal approach:

  • connect all landuse polygons
  • if possible, remove multi-polygon relations on landuse (split on kataster boundaries)
  • split landuse on highways:
    • always on secondary and tertiary
    • possible fill in landuse=highway (proposal was stopped by trolls, it's not optimal, but since landuse=railways is accepted, the optimal landuse=transportation can't be reached)
    • split on railway, fill in landuse=railway
  • connect landuse with areas tagged with natural=wood,scrub,etc.
  • maybe also landcover?

Historical Objects

for more details, please visit this subpage !

12-Aug-2014: the Kreis Viersen is "monument-free", see DE:CheckTheMonuments, beside the 2 real ones I know, Bismarkturm & Kreiskriegerdenkmal.

All the 'monuments' I found were wind/watermills, memorials, sculptures and one pillbox. Maybe we can find some more real monuments!

JOSM editing

WMS ALK vector offset

to compensate the offset, I averaged some positions in "Kreis Viersen" and got an average offset (east/north) of 2.13 -2.32. This works fine for my settings in JOSM (projection Mercator EPSG:3857).

Possible offset: 2.864 -2.101: not so good, but this would be the difference between 11709 and 11714. Let's hope I am wrong.
