CONTRACT NO.: W912P7-06-D-0001

TASK ORDER: TBD

CONTRACTOR: Towill, Inc

PROJECT: ARRA Funded Historic Aerial Photography

TITLE: Orthophotos for the Santa Rosa Plain and Russian River Areas

2. BACKGROUND

In January 2000, Towill, Inc. was tasked to conduct aerial surveillance photography of

the Santa Rosa Plain and the Russian River for the USACE San Francisco District. In

March 2000, about 300 exposures of color infrared photography were taken for both

areas. For the Santa Rosa Plain, nine (9) flight lines and 243 exposures were taken at a

scale of 1:12000 (1" = 1000') with 60% overlap and 26% sidelap. For the Russian river,

strip photography of ten (10) flight lines and 59 exposures were taken at a scale of

1:24,000 (1" = 2000') with 20% overlap. No aerial survey targets were placed or

surveyed as a part of this project. Towill, Inc. delivered one (1) set of contact prints, one

(1) set of flight index maps, and two rolls of aerial film to the USACE San Francisco

District.

The San Francisco District has a need to produce orthophoto imagery from the aerial

photographs flown in March 2000. A photo control field survey was not performed as

part of the March 2000 project and the Russian River project has limited stereo-overlap

(20%). A modified approach for producing the orthophoto imagery is required as a result

of these two conditions: 1) survey control points required to geo-reference the aerial

photos will be transferred from other existing map sources as a substitute for field survey

and 2) the National Elevation Dataset (NED) will be utilized as a substitute for stereodigitized

terrain data. The map accuracy resulting from this approach will be equal to or

better than standard USGS 1"-1000' digital orthophoto quads (DOQs).

3. OBLIGATION OF CONTRACTOR:

The Contractor will provide the services and

submittals as detailed in the following sections.

4. OBLIGATION OF THE GOVERNMENT:

Government personnel will be available

for advice, guidance, and comments on all work under this contract. Any comment,

advice and/or guidance given by the Government personnel will be to assist the

Contractor in performing the work and will not change the scope of work or release the

Contractor from performing all work required herein unless written notification of such,

signed by the Contracting Officer (CO) is received by the Contractor. Should the

Contractor require assistance from the Government in regards to this scope, they shall

contact one of the Government's points of contacts given in section 1 of this scope of

work. The Government's point of contact will then either assist the Contractor directly,

or provide an appropriate point of contact to answer the Contractor's questions.

5. DESCRIPTION OF WORK:

 

a. The AE shall request historical aerial film for Santa Rosa Plain and Russian River

from the District photo archives.

b. The AE shall scan the photography at a resolution of 12.5 microns (approx. 2000

dpi.)

3

c. The AE shall locate photo identifiable features on the scanned photo images and

use the best available existing maps to provide real-world coordinates for each

photo ID point. Acceptable reference data for the Santa Rosa Plain Area include

USGS Digital Ortho Quarter Quads (DOQQs), Color Ortho Quarter Quads

(COQQs) or other imagery and/or spatial data sources from State, County or

Local governments that have a known accuracy of 1" = 1000' or better.

Acceptable references data for the Russian River Area must have a known

accuracy of 1" = 2000' or better. No field work is to be performed under this task

order.

d. The AE shall obtain readily available terrain data, such as the National Elevation

Dataset, to be used in orthophoto production.

e. The AE shall create an ortho tiling system that shall result in file sizes that are

manageable for use by the District. A shapefile index of the tiles shall be created

and attributed with the image name. The tiling plan shall be submitted to the

District for review and approval.

f. All georeferenced imagery and shapefiles shall be delivered in Universal

Transverse Mercator (UTM), Zone 10N, National American Datum (NAD) 83

and a horizontal unit of Meters.

g. The AE shall produce orthophotography for the Santa Rosa Plain and the Russian

River areas (as shown on the map exhibit). The Santa Rosa Plain shall be

produced at a 0.25 meter resolution and the Russian river at a 0.5 meter

resolution. Orthophoto images shall be produced in both GeoTIFF and MrSid

formats.

h. The AE shall provide an index map showing the coverage and image name of

each orthophoto tile. The index map shall be in PDF format.

6. SUBMITTALS

The final delivery submittal shall consist of the following data:

(1) full frame image scans of aerial photography in MrSid format with no greater

than 1:10 compression;

(2) orthophoto index and tiling plan in PDF format;

(3) orthophoto tiles for each geographic area in both GeoTIFF and MrSid format;

(4) one mosaic-ed MrSid image for each geographic area

(5) an orthophoto index in shapefile format

(6) associated metadata files

All submittals shall be sent to Jane M. Hicks, at the address given in section 1 of this

scope of work. All submittals shall include a cover letter specifying the exact submittal

that is being delivered, the contract number, the task order number, and the date of

delivery. A copy of this cover letter shall also be sent to the addresses given in section 1

of this scope of work for the Contracting Officer (CO) and the Contracting Officer

Representative (COR). All electronic mail submittals should state in the subject line the

exact submittal that is being delivered, the contract number, the task order number, and

the date of delivery. The electronic mail shall also include an electronic carbon copy (cc)

to the Contracting Officer (CO) and the Contracting Officer Representative (COR).
