How the UTM coordinate system is designed?
The UTM system divides the Earth into 60 zones, each 6° of longitude in width. By using narrow zones of 6° of longitude (up to 668 km) in width, and reducing the scale factor along the central meridian to 0.9996 (a reduction of 1:2500), the amount of distortion is held below 1 part in 1,000 inside each zone.
How big is a UTM zone?
Each UTM zone spans 6° of longitude, from 84° North and 80° South. Zones taper from 666,000 meters in “width” at the Equator (where 1° of longitude is about 111 kilometers in length) to only about 70,000 meters at 84° North and about 116,000 meters at 80° South.
How are the 6 degree wide zones represented in UTM?
The layer symbolizes the 6 degree wide zones employed for UTM projection. This layer presents the Universal Transverse Mercator (UTM) Zones of the world. The layer symbolizes the 6 degree wide zones employed for UTM projection. World UTM Grid This layer presents the Universal Transverse Mercator (UTM) Zones of the world.
What does the world UTM grid symbolize?
World UTM Grid This layer presents the Universal Transverse Mercator (UTM) Zones of the world. The layer symbolizes the 6 degree wide zones employed for UTM projection. This layer presents the Universal Transverse Mercator (UTM) Zones of the world. The layer symbolizes the 6 degree wide zones employed for UTM projection.
What do the letters mean in UTM notation?
Universal Transverse Mercator (UTM) When working with a UTM notation, the zone plus a letter is specified. The letter usually represents a latitude band, as it does with MGRS/USNG. In some cases, N or S can be used to represent a North or South UTM zone.
What is the current coordinate system for ArcGIS?
Under Current XY, you can see that the current coordinate system for this map is WGS 1984 Web Mercator (auxiliary sphere). Web Mercator is a common projected coordinate system designed for web mapping applications.
