Transportation Map – GISS Introductory Class

Transportation Map – GISS Introductory Class

– [Instructor] The transportation map is one of the five primary maps that a GISS creates on an indecent. Specifications for the transportation map can be found on page 65 of GSTOP. The transportation map shows
access routes to the incident and is included in the
Incident Action Plan. Lesson Objectives. Explain the purpose and use
of the transportation map and describe the standard elements associated with the transportation map. Give examples of optional elements that could be included in the map and describe how the transportation map differs from other incident maps. Purpose. The purpose of the transportation map is to provide incident staff guidance on getting to and from the
incident in a safe manner. The main feature of the map is the surface transportation system, highways, streets, roads. It is important that each of these is legibly marked on the map. The transportation map shows the location of incident infrastructure,
the incident command post, camps, drop points, water
sources, evacuation sites, and other incident
features reached by road. This map is used to find directions for a ground-based delivery
of equipment, supplies, and personnel to, and the
removal from, the incident. It is prepared for operational briefings and included in the Incident Action Plan. It is also used by dispatch to assist incident resources traveling to the fire. Guidelines for producing
the transportation map are: standard ICS GSTOP symbology, generally produced as
letter size, 8.5 by 11, or tabloid, 11 by 17. Use black-and-white as the background to provide for clear
photocopying and faxing. Standard cartographic
elements include STANDL: scale bar, title, author, north arrow, date and time, and legend. SGD: source, graticule/grid, and map datum are recommended, but not required. If latitude/longitude graticule is used, map datum must be specified, so coordinates can be used properly for navigation, communication,
and other operations. The Situation Unit Leader will confirm which format of lat/long
to use and which map datum. Care must be exercised to not cover map features with legends or insets that might cover
transportation information. Standard data elements include: the incident perimeter, usually
with a shaded background, labeled division and branch breaks to help the user locate their destination and select appropriate travel routes, ICS point features, including
ICP, drop points, and camps, major roads, road names, and type. For instance, four-by-four only should be clearly shown and labeled. When needed, highlight
the main travel routes used to access divisions and drop points. Route restrictions, such
as bridge, weight limits, or one-way traffic are
essential safety components. Add arrows and text boxes to show this. Key landmarks help the user
orient to the incident area. Optional elements of the
transportation map might include: landmarks, to help the user
orient to known features, like prominent mountains. Distance labels and
mile markers aid drivers in estimating the time it will
take to reach a destination. Road blocks are often used on
incidents for public safety and are staffed by
security unit personnel. Administrative boundaries
provide reference to city, county, private, and
public land boundaries. Showing or highlighting rivers and lakes is another way to reference landmarks. When the incident is near
or within communities, it is important to show street names. Incident line features, especially containing an uncontain line, can help drivers recognize the environment they are traveling in. And a vicinity map can
be used to help staff get from the airport or towns to the ICP. Consider making a separate
map for this purpose, if the primary transportation
map becomes too cluttered. Early in the incident, the Situation Unit Leader
will prioritize the production of the IAP and the briefing
maps above all other products. A scanned copy of a road atlas
or a map from the internet can be quickly turned into a
serviceable transportation map with the adoption of fire perimeter, STANDL elements, and symbology. Production of the transportation map ideally lies with ground support unit, but they frequently do not have all the time or skill to produce it. Inform the Situation Unit
Leader if you do not have time to meet all the assigned work priorities. A topographic background is not necessary. In fact, the additional lines will often detract from the map’s readability. Remember, this map will be produced in black-and-white for
printing and faxing. Now, let’s take a look at a few examples. Here’s an example of a transportation map. This fire was near Klamath Falls, Oregon. It has the detail needed for someone to travel from the city to ICP and from there to the incident. Fire line features and topography may be less important on this map, but road names, travel
routes, and drop points are what this map is all about. All STANDL components are used
on this transportation map. It is not always necessary
to have a vicinity map, logos, or section lines on the map. When adding driving directions, use cardinal directions for turns. There may be a need for more than one type of transportation map for an incident. One for getting to ICP from
an airport or dispatch office and another for incident travel. This transportation
map from the Cedar Fire provides the user with
basic information needed to travel around the fire. Note the QR code that allows the user to download the map to a phone or tablet. Can you read the forest road
system in the background? This could have been a more useful map had these roads been legible. This transportation map
from the Pioneer Fire is unreadable in this view. When printed at 11 by 17,
size is not much better. A less-detailed version
of the transportation map was produced for the Incident Action Plan. The map was produced at this scale so that it could be used
as an E size briefing map and as a downloadable map
for smartphones and tablets, using the QR code on the IAP cover. When zoomed in, a large
amount of detail may be seen. The yellow highlight on
the forest road system provides the user with
clear identification of primary routes used
within the incident area. The location of hazard sites, the television repeater, weather station, and other features
accessed by road are shown. A pale gray-green was used
to show the fire perimeter. When used with the IAP map, the user will know which
portions of the fire are still actively burning,
so no perimeter line was used. Lesson Review. I explained the purpose and the use of the transportation map and described the standard elements associated with the transportation map. I gave examples of optional elements that could be included in the map and described how the transportation map differs from other fire incident maps.
