What is the extent of the UTM grid system?
UTM eastings range from 167,000 meters to 833,000 meters at the equator. These ranges narrow toward the poles. Northings range from 0 meters to nearly 9,400,000 in North zones and from just over 1,000,000 meters to 10,000,000 meters in South zones.

The UTM (Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide.
At what location in a UTM zone is there no distortion?
The narrow width (6° of longitude) of each zone ensures minimal scale distortion within a zone. Also a map derived from a secant cylinder has less overall distortion than a map from a tangent cylinder.
Do UTM zones overlap?
Overlapping grids Distortion of scale increases in each UTM zone as the boundaries between the UTM zones are approached. Around the boundaries of large scale maps (1:100,000 or larger) coordinates for both adjoining UTM zones are usually printed within a minimum distance of 40 km on either side of a zone boundary.
What is difference between UTM and TM?
As opposed to TM, in UTM the cylinder is secant to the surface; it intersects the globe creating two standard meridians 180km away of the central meridian. To more or less evenly distribute distortion across the zone, scale factor 0.9996 for the central meridian is used.
How do I find my UTM zone?
Calculate the eastern boundary of any UTM zone by multiplying the zone number by 6 and substract 180. Subtract 6 degrees to obtain the western boundary. Therefore to find the eastern boundary of UTM zone 11: Eastern boundary of zone 11 = (11 * 6) – 180 = -114 degrees.
What is UTM zone number?
The UTM system consists of 60 zones, each 6-degrees of longitude in width. The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the east. The military uses their own implementation of the UTM system, called the Military Grid Reference System (MGRS).
What UTM zone is BC in?
The UTM zones and grid Sequentially- numbered 1 through 60, from west to east, the starting point for the zones (and the common border between Zone 1 and Zone 60) is the 180-degree meridian of longitude, or International Date Line. British Columbia occupies 5 UTM zones: 7 through 11.
How to calculate the boundaries of an UTM zone?
Here’s How: UTM zones are all 6 degrees wide and increase from west to east starting at the -180 degree mark. Calculate the eastern boundary of any UTM zone by multiplying the zone number by 6 and substract 180. Subtract 6 degrees to obtain the western boundary.
What is the UTM zone?
How to Determine the UTM Zone. UTM, or Universal Transverse Mercator, is a geographic coordinate system that is used to project an area of the earth’s surface onto a flat two-dimensional map.
What coordinate system does Google Earth use for UTM?
Google Earth’s native coordinate system is geographic (latitude/longitude, WGS84). So if you have your coordinates in UTM (Universal Transverse Mercator), you need to convert them to geographic first before using them in Google Earth. There’s a small utility that makes using UTM coordinates in Google Earth a lot easier.
What does UTM mean?
Unified Threat Management (UTM) is a term first used by IDC to describe a category of security appliances which integrates a range of security features into a single appliance. UTM appliances combine firewall, gateway anti-virus, and intrusion detection and prevention capabilities into a single platform.
