  13. United States National Grid(USNG) • National standard since 2001 • Adopted by federal agencies • FEMA, DHS, NGA, USGS • Adopted by several states • Florida, Missouri, North Carolina, others • Minnesota (March 25, 2009) • Military Grid Referencing System • Metric system

  14. Why? • Multiple grids • Needed one for everyone • Need efficient location referencing • Need interoperability • Across jurisdictions • Local, state, federal, military

  15. What about Lat / Long? • Not intuitive • Degrees, minutes, seconds • Several formats • DMS, DMS.sss, DM.mmm, D.ddd • Longitude • + / - • West / east • Increases right to left

  16. What about Lat / Long? • How big is a degree? • It varies • 69 miles at the equator • Longitude gets smaller toward poles • 50 miles in Dakota County • Distance calculations are difficult

  17. Grid Zone Designation (GZD) 6 x 8 Degrees

  18. 100 Km Squares

  19. 10 Km Squares USNG:15T VK 75

  20. 1 Km Squares

  25. Scalable National Regional Local

  26. Precision and Truncation • 18SUJ2337106519 • 18S UJ 23371 06519 • 1 meter precision, full USNG designation • UJ2306 • Assume GZD (18S) • UJ – 100,000 m precision (100 km square) • 23 06 – 1000 m precision (1 km square) • 2337 0651 • 10 m precision • Assume GZD and 100 km square

  27. Truncating GZD • USNG:15T VK (100Km square) • VK is unique for 800 miles in any direction

  28. Critical Infrastructure Key Resources Vulnerable Population

  29. Deployment • Standard map products • Seamless across jurisdictions • Common Operating Picture • Critical infrastructure • Key Resources • Vulnerable population • Training • Use the USNG
