Great to see that! Just have a look at
osm.wiki/New_and_Changed_Ways#United_States
where we have collected ways that have been mapped in OSM first

One Year of OpenStreetMap

Congratulations! Your power lines in Maryland have been a good starting point for the Northeastern transmission grid!

US power lines are still incomplete

This map is intended to attract new mappers for some neglected areas. Since October 2010, this power network has grown remarkably, and each additional line may be considered as success.

This map is neither a proof that black areas are perfectly mapped (Chicago has still some gaps which need to be added) nor a proof that white areas are completely unmapped. Toolserver's powermap has almost as many white spots as my simple map which I have made with Kosmos, so there must be some untouched areas.

Anybody who wants to fill the white areas is welcome. Anybody who wants to leave the map as it is will be ignored.

It would be great if all streets looked like this one.

New contributors to OSM in Cleveland !

Two years ago, Detroit was a TIGER desert. Good examples like Cincinnati are spreading like a seed as they encourage other mappers to do the same.

Road Classifications

Functional road classification is a good starting point for reclassification of OSM roads:

US power lines are still incomplete

Update: there is also another powermap which covers the United States:

http://toolserver.org/~osm/styles/?zoom=12&lat=40.81767&lon=-74.21297&layers=B000F0FF0000F0FFF0000T

US power lines are still incomplete

This map tries to visualize mapped and unmapped areas so that interested mappers can improve unmapped areas. For technical reasons, it does not focus on special features like power stations which are visualized in the following very detailed map:

http://energy.freelayer.net/?zoom=8&lat=52.56802&lon=9.33476&layers=B00000

Rendering such a detailed map requires very good data (which is available for Northern Germany) and very much processing power.

The map above is a very rough sketch in order to start a discussion about power mapping quality.

US power lines are still incomplete

Each black dot represents a pylon, each yellow dot represents a substation.

Pylons prove that a human mapper has mapped there because TIGER lines do not include pylons.

Wie lange kann es dauern bis ein bestimmter Teil gerendert ist?

Der See war nicht als Fläche, sondern als unvollständiger Weg eingezeichnet!

Benennung von Wegen

path = begehbarer Weg (Vorschlag der deutschen OSM-Mapper)
cycleway = gut ausgebauter Radweg
footway = gut ausgebauter Fußweg
track = befahrbarer Weg
+tracktype=grade1 -> asphaltierter Feldweg
+tracktype=grade2 -> gut geschotterter Feldweg
+tracktype=grade3 -> stellenweise unebener Feldweg
+tracktype=grade4 -> schwer passierbarer Feldweg
+tracktype=grade5 -> kaum erkennbarer Feldweg
service = Privatstraße
unclassified = öffentliche Straße

OSM - Tensions?

Disagreements? Oh yes, especially in the German community! Try to ask the German forum for our disputed issues!

Accepting ODbL - yes or no?

City threshold - 50000, 80000 or 100000 inhabitants?

Displaying brothels - yes or no?
osm.org/?lat=53.548271&lon=9.961561&zoom=18

Mapping county roads (Kreisstraßen) as primary or secondary roads?
osm.org/?lat=48.97549&lon=8.47213&zoom=15

Mapping cycleways separately - yes or no?
osm.org/?lat=53.259106&lon=8.955942&zoom=18

Mapping footpaths as footway or path?
osm.org/?lat=53.229406&lon=8.777049&zoom=18
Cycleway/footway vs. path

Mapping motorroads as trunk or primary?
osm.org/?lat=53.5154&lon=8.4902&zoom=14

Using GPX or aerial photos?

The OSM community is usually tolerant and hardly anybody has quit our project due to a disagreement. One user was banned because he refused to read his mails.

Yours, FK270673

Spam bedeutet "unerwünschte Werbung"!

Das Tagebuch ist in erster Linie für Mitteilungen über neue Karteneinträge gedacht. Werbung ist hier eigentlich nicht erwünscht. Mitteilungen, die das eigene Hotel oder Restaurant betreffen (z.B. Inhaberwechsel oder geänderte Öffnungszeiten), sind ein Grenzfall, der in der Regel geduldet wird, weil es auch Auswirkungen auf die Karte hat.

Gruß FK270673

Willkommen in unserem Projekt!

Bei uns darf jeder sein eigenes Hotel / Restaurant / Theater eintragen, das ist sogar ausdrücklich erwünscht. Zumindest den Namen des Theaters (name=XYZ) hättest Du aber noch eintragen können!

More Newbie Road Madness

The highway tag for access roads depends on object importance:
- service for a single farm or single house or single shop
- unclassified for a bigger factory, entertainment park, hospital, mall, prison, school or small military base
- tertiary for a very big industrial complex or a university or a very big military base or a very big mall

There is no official guideline that distinguishes between big and small objects, but a tagging practice that looks good on the map. Tertiary roads are usually identified by their official route numbers (e.g. ref=CR 12 or ref=CR 179). The prefix (C, CH, CR or CTH) is depending on local usage.

County routes are usually a very disputed issue:
osm.wiki/United_States_roads_tagging#County_Highways
It is usual to tag county roads as tertiary as long as they have a reference number, e.g. CR 12. However, there are also good reasons to tag dirt country roads as unclassified if you have local knowledge about road condition.

We also collect a lot of other information like churches, parking lots, railroad crossings, restaurants, supermarkets, traffic signals and turning circles. Unfortunately, not every amenity is available in each editor, but JOSM offers many options. Feel free to ask whenever you find some missing or outdated features in the map.

Kartenexport

Hallo!

Der Export von Kartenausschnitten funktioniert um so besser, je kleiner das ausgewählte Gebiet ist. Ein einzelnes Dorf kann man relativ leicht exportieren, ein Export der gesamten Weltkarte in einer Datei ist zwar (noch) nicht ausdrücklich verboten, zwingt aber jeden Server zwangsläufig in die Knie! Ganze Bundesländer bzw. Staaten bzw. Kontinente müssen von einem speziellen Download-Server, z.B. http://download.geofabrik.de heruntergeladen werden, weil die Export-Funktion für solche Aufgaben nicht gedacht ist. Irgendjemand missbraucht diese Exportfunktion (mit seinem Programm?) durch massenweises (automatisches) Herunterladen großer Datenmengen und erschwert damit allen anderen die Nutzung!

Es gibt vier Möglichkeiten zum Export:
- OSM-Daten, die man nur mit speziellen Programmen (z.B. JOSM oder Kosmos weiterverwenden kann)
- Mapnik-Bild (die Karte als jederzeit verwendbare Grafikdatei)
- Osmarender-Bild (die Karte als Grafikdatei mit anderem Hintergrund)
- HTML zum Einbinden (nur Weblink)

OSM-Daten sollte man nur herunterladen, wenn man sich mit JOSM oder Kosmos etwas auskennt oder breit ist, sich dort hineinzuarbeiten! Für blutige Laien ist eine einfache Grafikdatei weitaus besser geeignet!

Started Editing Today, and Road Confusion.

Welcome to our project!

When TIGER data was imported in 2007, all other roads (tiger:cfcc = A41) have been automatically converted to "residential" which is definitively wrong.

The OSM classification of streets is roughly (!) following functional highway classification:
http://www.dot.state.ga.us/maps/Documents/rural/Telfair_FC.pdf
motorway = fast road with no at-grade intersections
trunk = fast road with some (!) at-grade intersections
primary = principal arterial roads (often equal to US roads)
secondary = arterial roads (often equal to state roads)
tertiary = collector roads (often equal to country roads)
unclassified = public roads (access to more than one house)
residential = urban roads
service = access roads (for one house, e.g. a single farm)
track = dirt roads (4WD only), usually not accessible for cars
+tracktype = grade1 (paved), grade2 (gravel), grade3 (dirt), grade4 (earth), grade5 (invisible)

Paved tracks may be used e.g. on a golf course or in a national park.

OSM EMPOWERING?

- Mappers of commercial companies are working in order to earn their crust (basic and safety needs)
- OSM members are mapping in order to map what they regard as sensible (self-actualisation needs)
(Abraham Maslow: The Hierarchy of Human Needs)

OSM EMPOWERING?

Contracts, prices and money:
- OSM is distributed for free, but not in vain.
- Mappers don't get money, but appreciation
- Rules cannot be enforced by contract, but by consent

OSM EMPOWERING?

Competition:
- Competition is not between companies, but between projects (e.g. between JOSM and Potlatch or between Mapnik and Osmarender)
