Are there 120 UTM zones?
UTM zones are six degrees wide. Each zone exists in a North and South variant. Universal Transverse Mercator Zone n (N) – The Northern Hemisphere projections for the infamous UTM system consisting of 120 zones (60 different zones with North and South variants of each).
What UTM zone is California in?
The UTM coordinate system breaks the world up into various blocks called UTM zones. A set of northing and easting values describe a position with respect to where it falls within a particular zone. Most of Northern California is in Zone 10, while most of Southern California is in Zone 11.
Which UTM zones cover the United States?
The UTM projection divides the world into 60 zones that begin at longitude 180º, the International Date Line. Zone 1 is from 180° to the 174° W longitude. The conterminous United States is within UTM zones 10 to 19.
How do I find my UTM grid reference?
To find the UTM coordinate of a point, “read right up”. The numbers designating the vertical gridlines (at the bottom or the top of map) are the easting values. The numbers to the sides of the map labeling horizontal lines are the northing values. In the map example below, grid lines are 1000m apart.
How many UTM zones cover the contiguous United States?
The Universal Transverse Mercator grid that covers the conterminous 48 United States comprises 10 zones—from Zone 10 on the west coast through Zone 19 in New England. In each zone,coordinates are measured north and east in meters.
How do I read my UTM coordinates?
When reading a UTM coordinate, your reading should state latitude and then longitude (eastings first, then northings). A useful mnemonic to help you remember this is “along the corridor, then up the stairs.”
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 does the term UTM mean?
The Universal Transverse Mercator (UTM) is a system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth as a perfect ellipsoid. However, it differs from global latitude/longitude in that it divides earth into 60 zones and projects each to the plane as a basis for its coordinates.
What is an UTM coordinate?
UTM is a planar coordinate system which provides a constant distance relationship anywhere on the map. In angular coordinate systems like latitude and longitude, the distance covered by a degree of longitude differs as you move towards the poles.
What is UTM in GIS?
UTM in gis means that:projected coordinate system in gis. universal transverse Mercator (UTM). This system divides the world up into60zones of longitude, each of width6°.
