== Duplicate City Name Error ==
==WMEBR Filter== <!--T:1-->
<p>WME will prevent you from adding a city name to a segment if
any segments in your state have the same city name, and they are more than a

few miles away. The error message <b>“The
highlighted road is too far from the city it was added to”</b> will be
displayed when you save. This is done to prevent elongated [[City_smudges | City Smudges]] in WME and the client.</p>
== Waze’s Original Solution ==
* [https://www.waze.com/forum/viewtopic.php?f=819&t=263628&hilit=wmebr+filter+script Forum page]
<p>Waze resolved duplicate city names when they launched the
* [https://greasyfork.org/fr/scripts/370855-wmebr-filter Greasy Fork page]
map three ways.
<br />
# When a small town was surrounded by a larger township of the same name, the smaller town was identified as <b>Foocity</b> and the larger municipality got the name <b>Greater Foocity Area</b>.  
#When the towns were separated by some distance, Waze appended a counting number behind the name. So you might see <b>Foocity (2)</b> and <b>Foocity (3)</b> on the map in addition to <b>Foocity</b>.
#Waze dumped the city name altogether, which is one reason you see gaps in the Cities layer and roads with no city name.</p>
<p>None of these are elegant solutions. Each state will need to
decide on a local solution if they want to clear duplicate names from their
state, as there are a wide variety of municipal configurations in the USA.</p>
== Better Schemes for Removing Duplication ==
<p>As long as the city name differs by one character, you will
not get the error message. But we don’t recommend kludgey fixes. The best way
to clear duplication is to find something unique, but accurate, that identifies
a municipality.
**If a borough and a township share the same name, rename the township segments to read <b>Foocity Twp</b>.
**In Pennsylvania, we have several instances of three or more townships sharing the same name. So we append the county name to the township name, <b>Foocity, Countyname</b>, since that is how they are uniquely identified to the state government.</p>
<p>The simplest scheme is to resolve conflicts in this order:</p>
<p>1. If a CDP (Census Designated Place as found on the [http://www.census.gov/geo/maps-data/maps/2010tract.html Census Tract Maps]) and a city conflict, append something
to the city name, since CDPs don’t have any other common appellation.</p>
<p>2. If a well-known city and a lesser-known city conflict the most well-known keeps the unadorned name.</p>
<p>3. If all else is equal, choose one to keep the original name, and add the minimum clear suffix to alter the others.</p>
== Changing an Entire City Name ==
<p>Using mass editing tools to change a city name on all segments
is strongly discouraged. The mass editing tools can lead to errors and loss of
data. The correct procedure is to contact your Region Coordinator with the old
city name, new city name and a permalink of the center of the area. The coordinator
will then ask Waze to make the correction in their database. A side benefit is any polygon with the old city name will be removed at the same time.</p>
== Cities Layer Purpose ==
<p>Currently, the cities layer in WME is only used to display
the city name and polygon on the client and provide a location for client
warnings. It is also believed to be used when you  search for a city in WME. Some users have speculated that this layer will be used for native address
search, but this has never been confirmed by Waze. </p>
== City Polygon Creation and Updating ==
<p>Many of the city polygons were created by Waze at the
original map import. They were not visible to editors in early versions of WME.
<p>Waze runs a server process regularly that looks for new
roads or road segments with changed city names. If the city name is new, a polygon
will be created to cover all the segments with the same name. If a polygon with
that name exists, Waze will sometimes expand or contract the polygon to match
the new road locations. Experience has shown that many of the older polygons resist
changes and remain the same shape, no matter what city name you apply to the roads.
Waze has never explained this.</p>
== City Polygon Removal ==
<p>Waze runs a server process periodically that removes city
polygons if there are no road segments with that name.  Experience has shown that many of the older polygons
are not removed by this process. Your Regional Coordinator can request that
Waze remove these polygons.</p>
