imagico (2017-01-09 16:38:48+00:00): Hello Elliott,

please be aware that such large movement of the coastline interrupts coastline processing for the main map on osm.org.  It would be advisable to perform such changes in a single edit after discussion in the local community.

To also consider here:

ElliottPlack (2017-01-09 20:23:13+00:00): Hi Imagico, thanks for the message. Despite the somewhat open-ended sounding changeset comment, I do believe these edits were faithful to the coastline continuity rules but let me know if I made an error. I have been doing the coastline work along the bay in manageable chunks. Looking at z5, I didn't think that it would affect the look on OSM.org strongly.

I have discussed these changes with some local editors but if you take a look at the coastline along here, you'll see that it doesn't get much attention. Separating it out as a water polygon would make it a bit easier to manage.

However, I will refrain from future coastline updates for now and speak to the community in more detail before resuming. We did have one talk-us thread about this which then (I thought) gave me approval to separate the smaller rivers.

Best,

Elliott
imagico (2017-01-09 21:05:13+00:00): My main reason for messaging you here is to let you know that this size of change affects the coastline processing and you plan future changes accordingly.

Independent of that I cannot really recognize the idea behind the current position of the coastline, i.e. why it is there and not further upstream or downstream.  The lowest parts of all these 'rivers' seem part of Chesapeake Bay, in particular what is mapped as Miles River here:

https://www.openstreetmap.org/relation/6840770

seems to be a side bay (Eastern Bay) with separate connections to the main bay in three directions (north, west and southwest) and likely dominated by tidal currents rather than river currents.  But i am no expert in this area so this is up to you to assess.

I remember there was a discussion on talk-us some time ago if to take Chesapeake Bay out of the coastline.  Removing all side bays makes less sense since you end up with a meaningless residual bay that mostly consists of vitual geometries (i.e. coastlines that do not actually represent the edge of a waterbody).

czubi (2017-01-15 16:03:07+00:00): Du hast in Neudietendorf 5 fixme's auf die Signale gesetzt.
Möchtest Du Bilder von den Signalen ?
Ich kann sie leider nicht unterscheiden.
bigbug21 (2017-01-15 17:49:52+00:00): Ja, das würde helfen, soweit die Bilder nach Anfang September 2016 entstanden sind (die Signale hatten sich dann verändert).
czubi (2017-01-17 16:22:56+00:00): Sind alle Signale mit 3 Leuchten 
Ks-Mehrabschnittssignal, dann schaffe ich es auch alleine ;-)
bigbug21 (2017-01-17 18:58:07+00:00): Wunderbar! Ks-Mehrabschnittssignale sind eindeutig an ihren dem gelben, nach unten gerichteten Pfeil zu erkennen.
czubi (2017-01-18 16:58:51+00:00): So der Anfang ist gemacht, am NÖ Ausgang in Neudietendorf stehen nur Mehrabschnittssignale. Mache ich jetzt nur das fixme weg oder muss ich nochwas ergänzen? Welcher Taggingeintrag kennzeichnet denn jetzt den Unterschied zw. z.B. einem KS-Hauptsignal und einem KS-Mehrabschnittssignal. KS ist doch nur das Signalsystem !?. Und warum steht an 13P3 funktion=exit und an 13P5 nicht? Sind das nicht beides Ausfahrsignale? Bin verwirrt ...
bigbug21 (2017-01-18 18:55:58+00:00): Du solltest schon die passenden Tags ergänzen. Mit JOSM und der entsprechenden Vorlage (https://wiki.openstreetmap.org/wiki/DE:OpenRailwayMap/Tutorial#Einbindung_der_Vorlage_in_JOSM) geht das auch relativ einfach. Und bei 13P5 habe ich wohl vergessen, das Funktions-Tag zu ergänzen.
czubi (2017-01-19 13:50:55+00:00): ... sorry, auch mit Vorlage erschließt sich mir der Unterschied im tagging zwischen einem z:b. KS-Hauptsignal und einem KS-Mehrabschnittssignal nicht. Habe einfach zuwenig Ahnung. Ich werde dir einfach in die Descriptions eine entsprechende Bemerkung machen. Vielleicht hilft es Dir oder anderen später weiter. Die fixme's löschen ich.
bigbug21 (2017-01-19 19:55:31+00:00): In der Vorlage kannst du Ks-Haupt und -Mehrabschnittssignale einfach auswählen und die entsprechenden Daten eintragen. Bitte ergänze doch wenigstens FIXMEs, dass das übrige Tagging fehlt.
czubi (2017-01-19 22:19:36+00:00): ... ja, hab ich mir angeschaut aber die taggings von Hauptsignal und Mehrabschnittssignal unterscheiden sich in der Vorlage für mich nicht. (Oder ich bin zu blöd es zu erkennen). Daher nochmal meine Frage, Wie unterscheiden sie sich?. Die Vorlage bringt mich nicht signifikant weiter. Die descriptions habe ich ergänzt, die fixmes gelöscht, da die Frage "ob Mehrabschnittssignal" dank deiner Hilfestellung (gelber Pfeil) da beantwortet ist.
bigbug21 (2017-01-20 07:02:15+00:00): Ks-Haupt- und Mehrabschnittssignale verwenden tatsächlich viele Tags gemeinsam, viele unterscheiden sich jedoch auch. Das elementare Tag ist einmal railway:signal:main=DE-ESO:ks und railway:signal:combined=DE-ESO:ks. Details: https://wiki.openstreetmap.org/wiki/DE:OpenRailwayMap/Tagging_in_Germany#Ks-Signale

Auch in der JOSM-Vorlage gibt es für die beiden zwei verschiedene Eingabemasken unterhalb von "Ks-Signale" auf der zweiten Ebene. Du musst eigentlich nur die Vorlage in JOSM einbinden, der Rest erklärt sich von selbst.
czubi (2017-01-20 13:18:37+00:00): ... sorry, Tomaten auf den Augen gehabt ;-)
Die nordöstlichen habe ich so gut ich es wusste gemacht, die Anderen folgen.
bigbug21 (2017-01-20 22:41:18+00:00): Alles klar. Danke!

But, I wanted to check with you to see whether that was the case or not--that way we don't potentially lose valuable data from a real user. So do you mind confirming whether this data was collected by you or if it was from another database/copyrighted geocoder? Thanks! user_5359

highflyer74 (2017-01-04 08:53:44+00:00): Hi!

Danke für die schnelle Rückmeldung. Du kannst ja nachforschen und es anpassen. Gruss aus HB!

PS Wenn Du Häuser zeichnest, denke daran, sie danach rechtwinklig zu machen. Das geht auch in iD. Ansonsten kann ich Dir JOSM (https://josm.openstreetmap.de/wiki/De%3AWikiStart) empfehlen. Der Editor ist komfortabler zu bedienen und warnt auch vor vielen potentiellen Fehlern.
