These are commonly referred to as “floating” branches. A branch may be assigned to an isolated area of an incident or another smaller incident within the main response area. The symbols used at the break between adjacent branches are point features and should be perpendicular (rotated if needed) to the fire perimeter.īranch break symbol may serve as both the break between branches and the break between adjacent divisions (i.e., replace a division break symbol).īranch breaks might not occur on the fire perimeter. and Bold (for 8.5x11 or 11x17 IAP map, scale accordingly for larger layouts/different maps).īranch labels are placed a good distance away from the fire edge, between the branch breaks symbols, and should not obstruct key features on the map. Map label example: Branch IV, font 18-24 pt. Typically consist of two or more divisions.īranches are identified by Roman numeral labels (or by functional name).įunctional branches oversee a specific function on the incident: Fire Suppression, Air Operations, Law Enforcement, HAZMAT, Structure Protections, etc.įire Suppression and Air Operations Branches are the most common found on wildland fire incidents. Division labels for divisions that are not on the fire perimeter are placed outside of the imaginary line between the division breaks. These are commonly referred to as “floating” divisions. The symbols used at the break between adjacent divisions are point features and should be perpendicular (rotated if needed) to the fire perimeter.ĭivision breaks might not occur on the fire perimeter. and Bold (for 8.5x11 or 11x17 IAP map, scale accordingly for larger layouts/different maps).ĭivision labels are placed away from the fire edge, between the break symbols, and should not obstruct key features on the map.Īs an incident winds down, adjacent divisions may merge into a single division or be combined (e.g., Div M/N/O), usually temporarily. It’s common to skip some division letters to allow for expansion of the incident (e.g., Div A, Div B, Div Y, Div Z).ĭivision map label example: Div A, font 18-24 pt. Usually start with “A” at the fire origin and progress in a clockwise order around the incident. Operations Branch Director ( OPBD) supervises DIVS on large incidents which contain branches.ĭivisions are identified by letters of the alphabet. Divisions exist within specific branches. A branch is the organizational level having functional or geographical responsibility for major parts of incident operations such as divisions. A Division Supervisor ( DIVS) supervises the resources assigned to a division. Use of Latitude and Longitude in wildland fire - USFS Information Bulletin 2010-02 Latitude Longitude.Ĭurrent layer files are in the GeoOps Incident Directory Structure.ĭivisions and branches divide an incident into geographical areas for the purpose of work assignments and delineating areas of operation.
Removal of Medivac symbol Memo and Interagency Aviation Accident Prevention Bulletin. Repair status symbols updated to follow the color wheel and allow better differentiation in colorblind individuals. The hazard point symbol has been revised. Planned Line symbols are now pink with dashed or broken symbols to better differentiate them from completed lines when printed in black and white. Latitude/Longitude information is displayed in degrees, decimal minutes, WGS 84 datum.ĭivision and branch break locations, event point attribution, and labeling should follow the guidelines in the references section below. See references below.Ĭhoice of symbol size is at the discretion of the Geographic Information System Specialist ( GISS) and the Situation Unit Leader ( SITL). National symbology standards should be used where appropriate. Symbols should be identifiable and clearly distinguishable from other Incident Command System (ICS) symbols, whether displayed in color or black and white.Ĭommon map conventions (e.g., blue for hydrologic features) should be observed, if possible, to ensure clear communication.
In the interest of encouraging safety, consistency, and readability, GeoOps describes the symbols that everyone should use when creating maps. 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.
