7141 - GEOMETRONICS ADMINISTRATION.
7141.04 - Responsibility.
3. National Forests. Forest Geometronic Coordinators. Each Forest
Supervisor shall designate, by name, a Geometronics Coordinator.
These coordinators shall serve as the Forest contact with the Regional
Geometronics Group Leader. The coordinators will also serve as the Regional
Advisory group for Geometronics products and services.
Orders for geometronics products (aerial photography, orthophotography, photo lab
orders, photogrammetric work, base series maps, special maps, digitizing, new
products, remote sensing, training) will be processed through the Forest/Area
coordinators. The products require adequate "lead time" for successful and timely
completion. It shall be the responsibility of each coordinator to see that Forest/Area
staffs are made aware of the amount of lead time needed and ensure that sufficient
lead time is provided when ordering these products.
Training/updating sessions will be held for the coordinators, as required, to review
geometronics processes, procedures, products, and services.
7142 - NATIONAL BASE SERIES. Region 10 base series map scales and their
intended uses are shown below.
7142.1 - Primary Base Series. (1:63,360 scale) Maps are derived from standard
United States Geological Survey quadrangles. They are revised/maintained on a 7year cycle, using the most current aerial photography. The maps are used for
detailed planning, layout, project level work, and as a base for generating other
geometronics products.
7142.2 - Secondary Base Series. (1:100,000 scale) These are planimetric maps
derived from Primary Base Series maps. This scale is intended for use in more
general planning, layout, and large project applications over a larger area.
7143 - CARTOGRAPHIC PRODUCTS. Region 10 special map scales and their
intended uses are shown below. Scales other than those listed can be used to
provide a wide range of user-oriented maps which will be derived from the base
series plates and layers. The Regional Office (RO) Geometronics Group shall
participate in developing additional scales and map standards.

7143.03 - Policy. Special maps will be derived from the base series when completed
maps are available covering the area of interest. When base series maps are not
available, an alternate selection of map source will be made depending on the scale,
format, and accuracy requirements of the assigned project.
1. Cost. Reference FSM 2336.
2. Approval for Publication of Maps. All maps and map products prepared in
Region 10 for distribution or sale to the public shall be edited and approved by the
RO Geometronics Group prior to publication. This includes maps derived from
digital data and maps produced by contractors for public use. The RO Geometronics
Group will perform a cartographic edit to ensure that each map or map product is
an effective graphic communication product that meets or exceeds Regional
publication standards for distribution to the public.
7143.11 - Forest Visitor Maps. (1:506,880 (1" = 8 miles) scale) This scale is
intended for use in providing National Forest visitors with detailed information on
National Forests and special interest areas. They are derived from the Secondary
Base Series and cover one complete Forest or Area.
7143.14 - Forest Visitor Guides. (1:250,000 scale) This scale is intended for use in
providing general information on National Forest recreation opportunities,
wildernesses, roads, trails, visitor information service developments, and public
awareness of resource management objectives. The format is an entire Ranger
District or other suitable subdivision of a Forest/Area, such as Prince of Wales
Island on the Ketchikan Area. They are derived from the Secondary Base Series.
7143.2 - National Special Purpose Maps. Scales for these maps will be developed,
as needed, for special purpose maps such as those needed to support Regional or
Forest planning. The RO Geometronics Group shall participate in developing
standards and shall support these mapping efforts.
7145 - REMOTE SENSING.
7145.11 - Recurrent Aerial Photography Plan.
1. Aerial Photography Specifications. A dual-camera installation consisting of
an 8.25-inch (209.6 mm) focal length metric camera and a 6-inch (152.4 mm) focal
length metric camera must be specified. Color infrared film processed to a negative
and panchromatic black/white film must be specified. Photography must be flown
1/4-quad centered at an altitude of 40,000 feet above sea level.
2. Funding. Procurement of recurrent high altitude aerial photography must
be funded by the RO Geometronics Group. Funding must be derived from
multiresource moneys and shall be included in the RO Geometronics Group's budget
for the scheduled year of procurement. Funds programmed for procurement of
aerial photography shall not be used for any other purpose without approval of the
Regional Engineer.

3. Procurement Administration. Flight plans and technical specifications
shall be prepared by the RO Geometronics Group. Procurement contracts shall be
administered by the Aerial Photography Field Office (APFO) in Salt Lake City,
Utah. A member of the RO Geometronics Group shall be designated Regional
Coordinator to work closely with the APFO to administer each contract.
Photography procurement must be supported by a ground change determination
analysis coordinated with each Forest by the RO Geometronics Group.
4. Coverage of Alienated Lands. Aerial photographic coverage of designated
wilderness, monument areas, and alienated lands (State and private lands,
municipal lands, reservations, and military installations) located within National
Forest boundaries shall not normally be acquired as part of this plan. However,
coverage of these exempted areas may be included in recurrent procurements, if
their exclusion would otherwise preclude efficient flight planning or if ground
changes are sufficient to warrant their inclusion for mapping purposes.
5. Prints to be Procured. Three completed sets of contact prints must be
procured. One set must be retained by the RO Geometronics Group
for use by the RO staff; one set must be distributed to each Forest Supervisor's
Office; one set must be distributed to each Ranger District. Additional prints shall
be furnished to provide duplicate stereo coverage along Ranger District boundaries
and, where applicable, along adjacent Forest boundaries. The RO Geometronics
Group must procure the required prints and make distribution to the Forest
Supervisor's Office. Any additional prints required by the RO staff or field units
must be ordered and paid for by the benefiting staff unit or benefiting Forest. Each
Forest shall also be provided one set of spot indexes (on mylar film for diazo
reproduction) showing the map position of each photo center.
7145.14 - Acquisition.
1. Procurement Responsibility. Forest Supervisors are responsible for the
procurement of large-scale aerial photography to meet their resource assessment
and inventory requirements.
2. Financing. The procurement of large-scale aerial photography shall be
funded by the benefiting Forest/Area from multifunctional funds.
3. Approvals. All large-scale aerial photography procurements must have the
approval of the Regional Engineer.
4. Procurement. Requests for procurement of large-scale aerial photography
shall be submitted to the RO Geometronics Group for review and coordination.

7148 - MISCELLANEOUS GEOMETRONICS SERVICES.
1. Electrostatic Plotters. The electrostatic plotters located in the RO
Geometronics Group are available to all Regional staff groups and all
Forest/District level units for the plotting of maps, charts, and miscellaneous
graphics.
The CalComp Model 5845 and Model 68444 electrostatic plotters are wide format,
high-resolution, raster plotting systems, and are capable of producing plots in over
1,000 colors. Each plotter is a nonimpact imagery device, utilizing electronic charge
deposition and image toning on specially treated dielectric media.
Each plotter accepts random vector format data, including ARC/INFO plot files. A
palette of 1024 colors is available for polygon fill plus a like number of color "pens"
in line widths from 0.004 to 0.0415 inch. Publication quality linework with very
precise registration of colors is produced at 400 dots-per-inch resolution while
plotting at a speed of 0.4 inch-per-second.
Plots up to 43-inches wide may be produced on paper, vellum, clear film, and matte
film; length is limited on the Model 68444 plotter to 32.8 feet; on the Model 5845
plotter, the length is limited to the length of the roll of plotting media. The output
plots may be modified by the plotter operator including plot scaling (change of
output size), plot rotation, plot position (positional change of plotted features within
media width limits), mirror image, and negative image. These plot modifications do
not affect the plot data but do change the appearance of the plot.
Payment for materials used to prepare plots shall be the responsibility of the
requester. Payment, via form FS-6500-46, is required prior to plotting. Current
costs for plots are:
R-10 SUPLEMENT 7100-93-2

a. Matte film..........$4.60/linear foot
b. Clear film..........$4.10/linear foot
c. Vellum..............$2.05/linear foot
d. Paper...............$1.10/linear foot
For purposes of calculating plotting costs, the plot length shall include the unused
areas between plots (called the plot header, which is 1.5 feet long), any unused
portion of the plotting media length, and the image area of the plot.
Plot data may be forwarded to the RO Geometronics Group on tape or via electronic
transmission. Tapes should be addressed to:
Dan Eldemar
USDA Forest Service
709 West 9th Street, Room 831D
Juneau, AK 99801
Concurrent notification via telephone at (907) 586-8736 that data tapes are being
mailed is requested.
