United States National Grid (USNG) National standard since 2001National standard since 2001 Adopted by federal agenciesAdopted by federal agencies –FEMA, DHS, NGA, USGS Adopted by several statesAdopted by several states –Florida, Missouri, North Carolina, others –Minnesota (March 25, 2009) Military Grid Referencing SystemMilitary Grid Referencing System –Metric system
Why? Multiple gridsMultiple grids –Needed one for everyone Need efficient location referencingNeed efficient location referencing Need interoperabilityNeed interoperability –Across jurisdictions –Local, state, federal, military
What about Lat / Long? Not intuitiveNot intuitive –Degrees, minutes, seconds Several formatsSeveral formats –DMS, DMS.sss, DM.mmm, D.ddd –Longitude + / - + / - West / eastWest / east Increases right to leftIncreases right to left
What about Lat / Long? How big is a degree?How big is a degree? –It varies 69 miles at the equator69 miles at the equator Longitude gets smaller toward polesLongitude gets smaller toward poles 50 miles in Dakota County50 miles in Dakota County Distance calculations are difficultDistance calculations are difficult
