2 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 2 GARS Overview Introduction History Stakeholders Functional requirements Implementation issues Examples Questions

3 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 3 Purpose Propose a response to the Service Chiefs request for a standardized area reference system SECDEF directed NGA to Take the lead in developing a global reference system that meets the requirements of the combatant commanders and Services

4 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 4 GARS History Common Geographic Reference System (CGRS) developed for CAOC use in OIF Dec 2003: ACC receives tasking to provide OPR to coordinate on Summit tasking form CSAF Define the requirement and include CGRS in NIMA chart production Mar 2004: CGRS Conference hosted by the Air Land and Sea Application Center Aug 2004: AWFC (98 RANW) CGRS Working Group Sep 2004: HAF/XO tasked ACC/DO for best way to implement CGRS into daily ops Nov 2004: Service Chiefs agree to implement existing ALSA model as training standard - request NGA develop global solution Dec 2004: The Service Chief letter is signed and at the CJCS Mar 2005: D/NGA receives tasking from SECDEF Mar-Aug 2005: Three working groups Nov-Dec 2005: Coordination of GARS proposal at AO & GO/FO levels via JS Jan 2006: D/NGA sends close-out memo to SECDEF

5 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 5 GARS Stakeholders Parties involved with local CGRS –ALSA & Air Warfare Center Interested parties for global implementation –Service GI+S Staffs – N096, A2/X, Army G2 & USMC –Doctrine developers ALSA – MTTP Developers Joint doctrine developers –Air Warfare Center –COCOM GI+S officers –NGA OMS, OGM, P, & E?

6 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 6 Global Area Reference System (GARS) - Functional Requirements - Scalable down to a minimum 5 x 5 min area Naming convention needs to be as intuitive as possible – entering argument either 1 deg or 30 min Areas coincident with map sheet coverage – 30 x 30 and 15 x 15 min areas Easy comparison between relative positions Based on Geographics (Latitude and Longitude) Must be on hard-copy charts – in some form No inherent operational security measures

7 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 7 Global Area Reference System - Functionality - Based on the expanded ALSA Common Geographic Reference System (CGRS) model w/a few changes Origin: 180 E/W & 90S World sub-divided into 30 min cells –East / West * –North / South * AA-QZ –Read OVER - then UP Quadrant Tiling –30 minute cells divided into 15 minute quadrants (numbered (1-4), left to right, top to bottom) –15 minute quadrants divided into 5 minute keypads (numbered (1-9), left to right, top to bottom) 6 Digits (EX: 419 LP 2) defines 15 x 15 min area

8 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 8 GARS Solution – Global Overview 30 minute cell identifier NOTE: 30 minute area divisions too small to show at this scale

9 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 9 Example: 134LV 30 minute cell identifier GARS Solution – Global Overview

10 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 10 AA AB AC AD AE AF AG AH AG39 006AG Origin Point 180 E/W & 90S 006 AG Cell to Quadrant to Keypad yields 5 min x 5 min cell; takes advantage of existing 1:100K and 1:50K charts Current 1:50,000 chart has symbology + to denote 5 x 5 keypads Each Quadrant Can Be Further Sub-divided Into Nine 5 min X 5 min Keypads Each Cell Is Sub-Divided Into Four 15 min X 15 min Quadrants 1:50,000 charts = 15 min x 15 min GARS Solution – Global Overview Each Cell Is 30 min x 30 min 1:100,000 charts = 30 min x 30 min

11 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 11 GARS – Implementation Roadmap Implementing GARS will require continued NGA- Service/COCOM interaction – work requirements Updates to Joint doctrine & NGA publications –CJCSI B: Position Reference Procedures –JP 2-03: JTTP for GI+S Support to Joint Operations –DMA TM : Datums, Ellipsoids, Grids, and Grid Reference Systems Standards activities –Inclusion in standard NGA production specifications –International standards – NATO STANAGs, etc Implementation on soft-copy/hard-copy products

12 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 12 GARS - Implementation Roadmap Plan of Attack: –Develop implementation plan with Services/COCOMs –Infuse into doctrine/policy –Service printing capabilities meet short-term need with CSAT producing GIS layer available on NGA Gateway –Effort level can be managed on a priority basis using chart series and geographic coverage area as discriminators –Will not obsolete any current NGA chart products –Implement as stocks deplete / product editions incremented –Limited chart series – 1:50K / 1:100K / 1:250K? / 1:500K? Chart body: graticule lines and text labels Neat-line: text labels along the chart edge Margin diagram of cells: depicting all cells for the chart Explanatory reference guidance diagram –Phased implementation

13 NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY Know the Earth…Show the Way UNCLASSIFIED 13 GARS - Implementation Phase 1 Phase 1 – DEMO GIS files currently available Represents 15 min and 30 min areas Hidden URL located at: –http://www.earth-info.nga.mil/GandG/coordsys/gars.htmlhttp://www.earth-info.nga.mil/GandG/coordsys/gars.html –Applications: Overlay for soft-copy products Within a GIS or mission planning system
