Universal Transverse Mercator

UTM

Similar to latitude and longitude…UTM

involves the intersection of lines of

reference…

Instead of the references latitude

and longitude…easting and northing

is used…

Planet earth is divided into 60 zones that are in concert with lines of longitude

Each of these zone lines are 6 degrees apart…and are designated zones 1 to 60…

these are easting values…

Within the United States, there are ten

zones…

The San Francisco Bay Area is in zone 10

There are also latitude bands that are 8 degrees apart and are designated C to X…I

and O are omitted…these are northing values

So San Francisco is in zone “10” and Band “S”..

Livermore is in the same zone and band…10S

The “10S” zone and band are further divided into 1000 meter squares that are used for navigation…

This is the easting coordinate

This is the northing coordinate

To find the position of the Wells use the zone and band designator 10S…

To find the wells coordinates…start with the easting value of 603000

Place the UTM guide at the bottom of the square in which the target is located…

Since this is a square that is 1000 meters square, 8 will represent 800 meters…add this to 603000 and the easting value is 603800…

The easting coordinate is 603800

To find the northing place the UTM guide along the right edge of the square in which the target is located

To find the northing coordinate start with 4171750

Since this is a square that is 1000 meters square, 7.5 will represent 750 meters…add this to 4171000 and the northing value is 4171750…

The northing coordinate is 4171750

So the complete UTM coordinate of Wells is

10S 603800 4171750!

10S 603800 4171750
