MapRaid SC Beachcomber Raid will be 21 June at 17:00 UTC (1:00 PM EDT) through 28 June 2015. The map raid will be divided into several groups, one for each section.

The raid hosts will be available across all areas for added support.

You will also be given a super region. Your goal as raiders should be to get your assigned area as complete and through as possible. Please don't edit outside your assign area unless directed to or with permission from a local host.

About this map raid

Please read the entire MapRaid wiki. If you are still uncertain what to do about something you see on the map, please ask your group leader Thank You for your help with the map.

What NOT to do

Mass Edit
DO NOT perform edits that affect large numbers of segments at once. We want to know who fixed what so we can understand how problems got resolved.
Add wayfinders
If you are 100% certain a wayfinder is needed, please ask HavanaDay, CrazyCaveman, or ialangford.

Group areas

You have editing access to a super region. Please stay within your assigned group area. If your group area is completely done, your group leader will assign you to one of the other groups for the remainder of the raid. Please use the mapraid overlay extension to keep track of your group area boundaries.

Mapraid UR Rules

We will follow the usual US UR etiquette with one exception: During the Map raid, the wait time is reduced to 4 days.

Do not close URs if the UR contains a tag such as [NOTE], [CLOSURE], or any other [MESSAGE]. Ask the editor who created the tag.

We use micro-doglegs to control turn- vs. stay/keep/exit instructions. Zoom in very close to see the closely-spaced geometry nodes. Preserve them.

Road Types, Names, and Functional Classification (FC)

In South Carolina , we follow the general US standards for road types based on the hybrid rule of FC and Route Type.

Some notes:

  • South Carolina Highways: SC-###.
  • State highway secondary system S-46-18 -- used as alternate name only.
    • The route number is a combination of county code (46) and road number (18)
    • If there is no other name on the sign, then the primary name should be Rd 18
    • If an interstate exit says County Rd 18, it is actually for a state secondary
  • County Road: CR-537, CR-4 are usually not signed. Only use this as the primary name if it appears on signs.
    • If it is called County Rd XXX it is NOT a county road -- it is usually a state secondary route (see above)
  • For SC and S numbers ONLY, use the SCDOT streetfinder
  • You can read more about road naming in South Carolina
  • If a road has more than one name follow the standard for Concurrent names on US roads.

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.

Watch here for results of promotions during and after the raid.
