This wiki page is complete.Editing Group assignments are complete, and the MapRaid is in full swing! Check this page and the MegaMapRaid page for changes at least once per day, as we will post updates regularly. Stay in touch in your assigned slack channel (not the general channel if you can avoid it)

Map Raid Baltimore is will run for approximately 4 days from Saturday, March 7, 2015 15:00 UTC through Wednesday, March 11. It is part of a wide-scale MapRaid known as MegaMapRaid.

Welcome to Baltimore!

Sign on MD-295 NB

Baltimore is the largest city in Maryland. Baltimore City is the largest independent city in the United States, meaning it is not included or merged with any other County. However, nearby Baltimore County borders the City on most sides.

Charm City has a unique culture, to say the least. If you want to experience some more of the 'eccentric' features of Baltimore as you edit follow these steps:

  • Rent/buy/stream Hairspray (1988) or Cry-Baby (1990) or the Wire (2002-2008). They are all fiction but have some truth to them.
  • Get some Old-Bay seasoning, and ignore the packaging. Put it on everything: seafood, french fries, chips, sandwiches, etc. Try using it on the rim of your bloody-mary too.
  • Speaking of booze, try some baltimore flavor (or lack there of): National Bohemian (Natty Boh) is the default beer for Baltimorons, but if you are looking for more flavor try Union Craft Brews, Brewers Art, or Heavy Seas.
  • Finally, complain about the weather. Right now its 20°F and snowing or icing, but in 6 months it will be 95°F and 100% humidity, so we really can't win.

Baltimore's history spans back to the british colonial times, as the Port of Baltimore. During the War of 1812, the City set the stage for Francis Scott Key to pen the National Anthem, the "Star-Spangled Banner". Through the 1800s-1950s, Charm City experienced growth as a result of trade and industry. In the 1950s to 1980s, Baltimore experienced drastic decline as the result of drugs, school issues, suburbanization, white-flight, and the loss of jobs associated with historic industrial operations. The History of Baltimore Wikipedia page has lots more information.

Today Baltimore is fighting to reclaim jobs and revitalize its downtown area. Popular Inner Harbor attractions such as the National Aquarium and events such as the Grand Prix and Star Spangled Spectacular have shifted the cities attention to downtown tourism opportunities. However, communities further from the downtown core, especially to the west and south, have struggled as blight and crime continue to weigh on the city.

Baltimore City Roads

Baltimore City is unique in Maryland as the City's Department of Transportation assumes responsibility for all roads, from surface streets to interstate highways. Only the tolled tunnel facilities are operated and maintained by the State's Department of Transportation. However, Baltimore County roads are constructed and maintained through either the County or the State depending on the size and importance.

Raid Areas

add google maps link to groups and location of raid map

Raid Groups

add group size and location, and what the editors will focus on

PUR Areas


Our primary mission will be to handle the URs, and PURs, followed by Place validation, and general map verification.

Functional Classification (FC) has been fully implemented for the Baltimore area. Some road types deviate intentionally from the state DOTs classifications. If you find a road which you feel is not classified correctly or set to the right type, please contact a local champ or State Manager (SM) before making changes.

Local Hosts

CBenson (PM) - Mid Atlantic Regional Coordinator - generally available during daytime hours

kodi75 (PM) - State Manager - generally available on weekends, evening hours during the work week.

JasonN899 (PM) - Area Manager - flexible hours, change daily, mostly evenings

nzahn1 (PM) - Area Manager - generally available during weekends, and weekday evening hours

Bugladen (PM) - Area Manager - generally available during ???? hours

jr1982jr (PM) - Local Editor - generally available during daytime hours


Please do not alter any of the following road types without first consulting a Local Host: Freeway, Ramp, Major Highway, minor Highway, Primary Street.

Please do not mass-edit Do not perform edits which will affect large numbers of segments at once. The edit history of segments is highly valuable in the process of solving URs. Mass editing effectively mass erases this history, permanently. We ask that all necessary processes which might affect large portions of the map, or long stretches of roads, be reserved until near the end of the MapRaid. This includes the “Select entire street” function.

Anything locked at 5 or 6? Please check with a local editor before making changes. Rank 5 and 6 editors - consider keeping highlights active for locks 5 and 6.

Close nodes We make extensive use of the "micro-dogleg" technique, where a geometry node is carefully placed, at full zoom, directly next to a junction node, in order to set the angle to create a desired Turn/Stay/Exit prompt. Please watch for these if you move any junction node, and be sure to recreate the same angle at the new location.

Local Guidance

Functional Classification

In the United States, we set our road types using a national standard called Functional Classification (FC). You can read a detailed explanation in our Road Type Wiki

The Functional Classification has been completed in the Greater Baltimore Metro Area. Occasionally, we find short segments that were missed in the selection process for conversion, and it is important that these be corrected for routing continuity. In general, however, we ask that Road Types not be changed without consulting one of the Local Hosts. In isolated cases, we have chosen to deviate from official classifications, due to errors or outdated information in the MdTA FC maps, or to better accommodate real-life situations and Waze quirks. It is important that these remain intact. Sometimes dirt roads may appear higher on FC maps but shouldn't be used by Waze for routing.

If you find an area that doesn't seem to be complete please bring it to the attention of a Local Host for review.

FC Maps

We have .KML maps available, compiled by nzahn1 (PM). Please contact him directly if you have any questions about the maps.
FC Maps

Locking Rank

In MegaMapRaid we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.

MegaMapRaid Minimum Locking Rank Standard
Segment Type Urban  Rural
 Freeway  5 4
 Ramp  5 4
 Major Highway  3 2
 Minor Highway  2
 Primary Street  2
 Street  1
 |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-|  2
 • • • • Ferry • • • •   5

Note that these are minimums and, for protection, certain segments may be at higher lock levels. If you find a road locked to a higher level than its minimum, please leave it locked no lower than that level when you have finished editing.

Place Editing

Not only were our URs and PURs out of control, places from both editors and trusted users have become a major issue. Misspelled names, wrong categories, missing addresses (EVERY business place should have an address!!) poor location and incorrectly assigned photos are all over the map. Use the powerful Place Browser (link below) and the information on the Place editing page to get these places corrected.

Gas Stations
Gas Stations should be locked to level 3 but, only after all data fields in the gas station have been filled. At least ensure that Brand, Name and Address have information. Remember to ask a hosting local if you need help identifying gas station information. Please read the Gas Station page for details about how to maintain gas station Places.

For editors below rank 3, once you have completely filled out a gas station with the min required information, please ask for a lock request.

Toll Roads / HOV / HOT / Truck Lanes

It is our custom to mark the Toll checkbox only on the entrance segments to Toll Roads. HOV and HOT road types have already been set correctly according to our local practices. If you have a question about one of these lanes, please contact a Local Host.

To learn more about HOV lanes read more in the Editing Manual

Special case: Do not alter the ETL (Electronic Toll Lanes) on I-95 North/South. Yes they are highlighted by validator as being a 2-way freeway, but no, its not an issue.


There are a number of major construction projects in process within the overall MapRaid area. These construction projects can cause frequent intermittent road closures. Many closures change daily and cause great numbers of URs to appear. When handling URs in one of these areas, be aware that reports of "Turn not allowed", "Missing road", "Wrong driving direction" are common, but may not indicate a map problem that can be fixed, because the physical road situation will change before our edits can take effect.

Baltimore City DOT closures are only intermittently reported on its Traffic Advisory webpage.

Baltimore County closures are frequently posted on the the County's Road Closure webpage, but some details are often missing.

Maryland Highway Administration posts its closures for state roads, highways, and interstates to the CHART website.

Local Hosts will attempt to keep editors informed of closures as they are discovered. The sheet below will serve as a database of closures, especially those not listed in the Official Waze Closure sheets:



DO NOT map NEW alleys without FIRST gaining approval from a Local Host (Area manager or higher).

If alleys are mapped (e.g. Baltimore City, Metro area), the road type should be set as Parking Lot Road; the other attributes (Name, city, direction, turn restrictions) should be set according to best practices like any other drivable road.

Please ensure use of GIS data and/or Street View to confirm the name of the alley.

Waze will route to the closest segment for a set of destination coordinates which may result in the destination being along the alley way.

To try to prevent this issue, please check the House Number and ensure it is closer to the "Named Street" and not the alley.

Refer to the FAQ for additional information.

UR & MP Guidance

Also, always leave a closing comment; no UR should be closed without one.

Mapraid edit lists

Spreadsheets and forms are being used to streamline management of various group efforts and track important edits. Below you can find links to use these these forms, sheets, and see the lists.

Scheduled Edits

These are edits which need to be completed but must be postponed in order to retain history for UR Solving. These edits are designated to specific editors to complete, once they get the green light from the MapRaid! leaders.

Boots on the ground

We need local boots on the ground to check things. Please add requests for locals to go and scout things in person, as in on the road. Some examples when this would be used include to check and see if:

  • The street view is accurate,
  • A road is really closed,
  • A turn really allowed/prohibited, etc.

To make a new request, or respond to an existing request, please use this form.

MapRaid Promotions

Some editors really let their bright side out, and let their community skills shine. This is even more evident in a concerted group effort with high-density editing like a MapRaid!. Editors of all ranks working closely with each other and the Champs, really lets us everyone get to know each other, and allows certain editors to be recognized for their skills and effort.

When the Champs see someone consistently editing well, interacting well with the community, and knowledgeable of the various details from the Wiki, they can issue promotions. This can be anything from the size of a managed area, to a rank increase, or even a new role.

The following editors have all earned our respect, and gratitude for a job well done. Not all received a promotion, but all were noticed and appreciated.
