Symbology

Purpose

Standard symbols in mapping wildland fires facilitates fast and consistent interpretation of mapping products and helps prevent ambiguous map interpretation, which can become a safety issue during an incident. In the interest of encouraging safety, consistency, and readability, GeoOps describes the symbols that should be used when creating maps.​

The following applies:

  • Symbols should be identifiable and clearly distinguishable from other Incident Command System (ICS) symbols, whether displayed in color or black and white.
  • Common map conventions (e.g., blue for hydrologic features) should be observed, if possible, to ensure clear communication.
  • National symbology standards should be used where appropriate. See references below.
  • Choice of symbol size is at the discretion of the Geographic Information System Specialist (GISS) and the Situation Unit Leader (SITL)​.
  • Latitude/Longitude information is displayed in degrees, decimal minutes, WGS 84 datum.
  • The Point Feature symbology specifications table should be referenced for label requirements.
  • The Label attribute is typically used to dynamically label all Point features, with the exception of Division, Branch, and Zone Breaks.  Dynamic labels can also be used for Line or Polygon features when needed (e.g., Management Action Points).  All labels, if turned on, will label on the Label field in the attribute table by default.
  • Division, Branch, and Zone labels should be placed between assignment breaks, using the Label Point Feature Layer.
  • Secondary symbols are derived from the same data as the primary symbols and used in conjunction with them.  For example, Repair Status is an attribute on Accountable Property, Event Point, and Event Line. The Repair Status Service is a view of the same data but symbolized on the Repair Status attributes. When displayed in conjunction with the primary layers, it visualizes the Feature Type and Repair Status to the end user.

Responsibilities

The SITL ensures that standard map symbology is used for mapping wildland fire incidents. The GISS uses the standard GIS map symbology and, if applicable, standard map symbol colors but may adapt (e.g., enlarge, use halo) the symbology for map readability while maintaining the essential design of the standard symbols.

6 Minutes for Safety Subcommittee

As we approach the 2025 Week of Remembrance (WOR), June 30–July 6, we dedicate this time to reflect on the past incidents from 2015 and honor the fallen through learning. Since its inception in 2014, WOR has honored wildland firefighters who made the ultimate sacrifice while encouraging critical discussions that reinforce lessons learned.

Throughout the week, we encourage thoughtful and generative conversations—whether in briefing rooms or at tailgates—that promote a culture of continuous learning and safety.

ETC Equipment Bulletin: 25-003 Flame-Resistant Shirt Survey

Date: June 12, 2025
Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.
