COMMERCE BUSINESS DAILY ISSUE OF JANUARY 27,1995 PSA#1271Defense Mapping Agency, ATTN: AQWM MS D-5, 4600 Sangamore Road,
Bethesda, MD 20816-5003 76 -- CONTROLLED IMAGE BASE SOL DMA800-95-R-5001 DUE 040395 POC
Contact Vance Cathell, Contract Specialist, 301-227-1904, Phil
McConnell, Contracting Officer, 301-227-2334, FAX 301-227-4793 The
Defense Mapping Agency requires the production of an imagery database.
The requirement is for an unclassified broad area database of imagery
with sufficient resolution (5 to 10 meter) to serve as an image
backdrop for mission profile development and to provide geopositioning
and perspective view generation. The data base must be in a format
compatible with National Imagery Transmission Format Standards (NITFS)
and in a compressed form on CD-ROM or 8 mm Data Cartridge Tapes. This
database, or Controlled Image Base (CIB), will be developed from
available digital imagery, which could include Satellite Pour
l'Observation de la Terre (SPOT), LANDSAT, or other sources. SPOT
imagery will be Level 1A Panchromatic scenes with a pixel resolution of
10 meters. Each SPOT image or scene covers a minimum surface area of 60
km by 60 km and a maximum of 60 km by 81 km depending on the viewing or
incidence angle of the High Resolution Visible (HRV) push-broom
scanners which collect the imagery. LANDSAT has a pixel resolution of
30 meters and must be resampled to 10 meters. However, it covers nine
times the area covered by one SPOT Scene. Other sensors may also be
used when ephemeris data is available. Uncorrected imagery is used to
take advantage of a rigorous satellite model that is applied with
ground control and tie points in a block restitution over multiple
images, and an advanced resampling technique that preserves the
original radiometric and geometric fidelity of the acquired scene
radiance. Individual images are geometrically corrected and
orthorectified to the Equal Arc-second Raster Chart/Map (ARC) system
used by DMA's ARC Digitized Raster Graphic (ADRG) product. DMA Level I
Digital Terrain Elevation Data (DTED) must be used to correct image
displacement due to terrain relief. In general, CIB will not be done if
there is no DTED unless approved by DMA or in flat terrain areas.
Multiple images are mosaicked, radiometrically balanced, resampled and
Compressed, 8 to 1 using the Vector Quantization (VQ) Algorithm to
form frame files formatted in accordance with Raster Product Format
(RPF). Multiple CIB Frame Files are delivered on CD-ROM in an output
format directly compatible with National Imagery Transmission Format
(NITF) Standards. A second version of the data is required on 8
millimeter data cartridges (EXABYTE) for entering the CIB data to the
DMA Database. This version of CIB will be radiometrically balanced and
will be generated before the compression step. It is anticipated that
a benchmark must be successfully completed in order to be considered
for award. A requirements type contract is anticipated to include one
base year (the remainder of FY95) and four option years. It is
anticipated that the unit of procurement will be by the cell, with an
estimated 720 cells to be ordered during the duration of the contract
if all options are exercised, although crises support could effect that
estimate. The delivery schedule will be determined by delivery order.
Only written requests for the solicitation will be accepted. No verbal
requests will be accepted. This requirement is subject to the
availability of funds. (0025) Loren Data Corp. http://www.ld.com (SYN# 0439 19950126\76-0001.SOL)
