This wiki page is still under construction. Information on this page will change throughout the day. Please wait for the official announcement for when the MMR raid wikis are ready

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

Please be sure to explore the Wiki page. Also, check back regularly in case of added materials.

Welcome to Baltimore!

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

Raid Areas

add google maps link to groups and location of raid map

Raid Groups

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 {Username|nzahn1}}. 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.

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.

Special case: Do not alter the ETL (Electronic Toll Lanes) on I-95 North/South


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.




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.
