Summary
Abstract: ARC Digitized Raster Graphics (ADRG) is for use in any application
requiring display of a map image or manipulation of the image of a map
in raster form. Digitized Raster Graphics (ADRG) are digital raster
representations of MCE and NIMA's paper graphic products. The
information content of ADRG is the same as that of the base map or
chart. Standard paper maps/charts are converted into digital data by
raster scanning and transforming the map image into the ARC system
frame of reference. Data collected from a single chart/map series and
scale will be maintained as a worldwide seamless database of raster
graphic data with each pixel having a distinct geographic
location. For distribution ADRG data is divided into geographic data
sets called Distribution Rectangles (Drs). One or more Drs fit onto a
single CD-ROM. The defined boundary of a Dr is the minimum bounding
rectangle that encloses all the input source graphics contained in the
DR. Raster graphic data from adjacent DR's abuts exactly to provide
unbroken coverage. However, gaps in coverage may occur as a result of
datum transformations and incomplete source graphic coverage. Overlay
may occur with unique maps such as 50,000 topographic line maps where
coverage is country oriented. The information content is the same as
the hardcopy map. Data files contain scanned image data. Header
records for source definition as well as a reduced resolution image
overview file for the entire CD-ROM. ADRG has been produced from paper
maps in the following scales: 1:5,000,000 General Navigation Chart
(GNC), 1:2,000,000 Jet Navigation Charts (JNC), 1:1,000,000
Operational Navigational Charts (ONC), 1:500,000 Tactical Pilotage
Charts (TPC), and 1:50,000 Topographic Line Maps (TLM), City Graphics,
Combat Charts, and Nautical Charts. Stock numbers for existing CADRG
and ADRG are listed in the Aerospace Products Semiannual Bulletin
Digest (stock number CATP1UBD) and topographic Products Semiannual
Bulletin Digest (NIMA stock number CATP3V01UBD). In most cases, the
ADRG stock numbers directly correspond to the sheet number of the
paper map stored as ADRG on the CD-ROM. In the case of JOGs (normally
four are scanned into one CD-ROM), paper map stock numbers can be
cross referenced to ADRG stock numbers using listings in the
Aeronautical Products Semiannual bulletin Digest for JOGs and in the
Topographic Products Semiannual Bulletin Digest for TLMs. This
cataloging system is being replaced with a dedicated ADRG catalog. The
Coordinate Reference System is the ARC (equal Arc second Raster
chart/map) System (Rectangular Projection). In the ARC reference
system the world is divided into 18 latitude zones to obtain equal
spacing with minimal distortion. ADRG is releasable to DoD, its
contractors, and other Executive Agencies supporting DoD activities.


Purpose: Provide a general purpose data set of support data and computer
readable digital images of hardcopy graphic products for map displays
on command and control systems, mission planning systems, and aircraft
cockpits.
