moving map displays.<br />
• Frame file versioning.<br />
• Rely on specific data management needs.<br />
• MIL-PRF-32283<br />
• 24 bit<br />

<strong>NGA</strong> <strong>GeoPDF</strong> Support<br />
UNCLASSIFIED<br />
• The <strong>CADRG</strong>/<strong>ECRG</strong> program was a natural fit to support <strong>GeoPDF</strong> production.<br />
• We are currently integrating the <strong>GeoPDF</strong> output into the current ADRG<br />
production system.<br />
• <strong>NGA</strong> will be replicating the <strong>GeoPDF</strong> efforts we are currently used to from the<br />
AGC.<br />
• The <strong>GeoPDF</strong> program will be synchronized with the <strong>CADRG</strong>/<strong>ECRG</strong> program<br />
which stays current with new map and chart production.<br />
• <strong>NGA</strong> is fully committed to a standards based approach to <strong>GeoPDF</strong> production.<br />

Raster Data Warehouse<br />
UNCLASSIFIED<br />
Details<br />
• The Raster Data Warehouse is a repository of up-to-date/current edition <strong>NGA</strong><br />
charts stored in the ADRG format.<br />
• 60,500 current charts.<br />
• 6 TB of data.<br />
• Catalogued by Series<br />
• 300 charts are produced per month<br />
Feasibility<br />
• Receive newly printed charts directly from the printing press.<br />
• Check DLA holdings regularly for new or un-worked charts.<br />
• Use PMAA database to identify new or un-worked charts.<br />

<strong>GeoPDF</strong> Production<br />
UNCLASSIFIED<br />
Backlog<br />
• Review the edition/currency of the<br />
current. <strong>GeoPDF</strong> RDW received from the<br />
<strong>Army</strong> <strong>Geospatial</strong> <strong>Center</strong>.<br />
• Order new editions and process into<br />
<strong>GeoPDF</strong>s.<br />
• Determine gaps in country coverage,<br />
order new editions and process into<br />
<strong>GeoPDF</strong>s.<br />
Concurrent<br />
• Continue to produce ADRG as usual.<br />
• Output ADRG and <strong>GeoPDF</strong> from the<br />
same input.<br />
• Operator controls the chart one time and<br />
produces two output files.<br />
Mirrored RDW<br />
• At some point, both RDWs<br />
(ADRG/<strong>GeoPDF</strong>) will mirror each other.<br />
• The <strong>CADRG</strong>/<strong>ECRG</strong>/<strong>GeoPDF</strong> will be<br />
produced with their most current editions.<br />
• However, titles and distribution schedules<br />
will vary.<br />

Country Index<br />
UNCLASSIFIED<br />
• Developing new process to build the Country Index.<br />
• Rely on COTS as much as possible.<br />
• Greater flexibility to customize the product, update, and fix issues.<br />
• Improve the Cartographic look.<br />
• Country Index will be delivered with the same functionality as the AGC provided.<br />
• Distribution will be done by Country.<br />
• Hot areas will be the first to be completed.<br />
• The first release will be the AF Country ROM.<br />
• We added 829 TLM 50K, City Graphics, ICMs (almost 1000 new charts) to the AF disk as well as<br />
updating old editions.<br />
• The AGC noted some issues with the initial release, the issues will be corrected, therefore the first<br />
edition from DLA will be correct.<br />
• High interest countries will be stocked first at DLA, the distribution of lower priority areas is TBD and<br />
may be web based.<br />
