== Duplicate City Name Error WMEBR Filter==<!--T:1-->
<p!--T:2-->WME will prevent you from adding a city name to a segment ifany segments in your state have the same city name, and they are more than afew miles away. The error message <bi>“Thehighlighted road is too far from the city it was added to”WMEBR Filter</bi> will bedisplayed when you save. This is done a [[Scripts|script]] to prevent elongated filter the [[City_smudges Place update request| City SmudgesPURs]] in WME and results on the client[ WMEBR website] to only show what we can handle.<br /p>
== Waze’s Original Solution == <p!--T:3-->Waze resolved duplicate city names when they launched themap three ways.# When a small town was surrounded by a larger township of the same name, the smaller town was identified as <b>Foocity<* [https:/b> and the larger municipality got the name <b>Greater Foocity Area</b>www. #When the towns were separated by some distance, Waze appended a counting number behind the namewaze. So you might see <b>Foocity (2)</b> and <b>Foocity (3)<com/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.<forum/p> <p>None of these are elegant solutionsviewtopic. Each state will need todecide on a local solution if they want to clear duplicate names from theirstate, as there are a wide variety of municipal configurations in the USA.</p> php?f=819&t= Better Schemes for Removing Duplication 263628&hilit== <p>As long as the city name differs by one character, you willnot get the error message. But we don’t recommend kludgey fixes. The best wayto clear duplication is to find something unique, but accurate, that identifiesa municipality. *Examples**If a borough and a township share the same name, rename the township segments to read <b>Foocity Twp</b>. wmebr+filter+script Forum page]**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 postal area or CDP (Census Designated Place as found on the [httphttps://www.censusgreasyfork.govorg/geofr/maps-datascripts/maps/2010tract.html Census Tract Maps]) and a city conflict, append something to the city name, since CDPs and Postal areas don’t have any other common appellation.</p> <p>2. If a well370855-known city and a lesserwmebr-known city conflict, the most well-known keeps the unadorned name.</p>filter Greasy Fork page]<p>3. If all else is equal, choose one to keep the original name, and add the minimum clear suffix to alter the others.<br /p> == Changing an Entire City Name == <p>Using mass editing tools to change a city name on all segmentsis strongly discouraged. The mass editing tools can lead to errors and loss ofdata. The correct procedure is to contact your Region Coordinator with the oldcity name, new city name and a permalink of the center of the area. The coordinatorwill 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. Merging two cities should also be handled the same way.</p> == Cities Layer Purpose == <ptranslate>Currently, the cities layer in WME is only used to displaythe city name and polygon on the client and provide a location for clientwarnings. 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__NOTOC__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 theoriginal map import. They were not visible to editors in early versions of WME.</p> <p>Waze runs a server process regularly that looks for newroads or road segments with changed city names. If the city name is new, a polygonwill be created to cover all the segments with the same name. If a polygon withthat name exists, Waze will sometimes expand or contract the polygon to matchthe new road locations. Experience has shown that many of the older polygons resistchanges 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 citypolygons if there are no road segments with that name.  Experience has shown that many of the older polygonsare not removed by this process. Your Regional Coordinator can request thatWaze remove these polygons.</p>{{Bottomline}}
