Coordinate Systems: UTM and Beyond

Question 1

What measurement does UTM use?

Answer 1

Meters

Question 2

Is UTM 2-D or 3-D?

Answer 2

UTM is 2-d planar! Long and lat is 3-D polar!

Question 3

What projection does the UTM use?

Answer 3

Transverse Mercator projection.

Question 4

What degree North and South does UTM cover?

Answer 4

84 degrees N and 80 degrees S

Question 5

Universal Transerve Mercator:

Answer 5

coordinates define 2 dimensional, horizontal positions.

Question 6

What degree wide is each UTM zone?

Answer 6

6 degrees wide

Question 7

What does each zone have?

Answer 7

A central Meridian!

Question 8

Whats the case with eastings?

Answer 8

eastings are measured from the central meridian eastwards. However eastings increase eastward from the central meridian which is given a false easting of 500 km so that only positive eastings are measured anywhere in the zone.

Question 9

Whats the case with northings?

Answer 9

Northings increase northward from the equator with the equators value differing in each hemisphere. In the northern hemisphere the equator has a value of 0. Four southern hemisphere locations the equator is given a false northing of 10,000km.

Question 10

degrees and measurements of a zone!

Answer 10

zone is 6 degrees wide! The distance between line of longtidue (width of a degree of latitude) at equator is 111km approximately so zone is never more than 666,000 meters wide.

Question 11

How many zones?

Answer 11

60!

Question 12

What zone does Saskatchewan use?

Answer 12

zone 13!

Question 13

UTM coordinates consist of 4 pieces of information.

Answer 13

1. ) The hemisphere, north or south.
2. ) The UTM zone, a number between one and 60
3. ) An easting, a positive number with 6 digits.
4. ) A northing, a positive number with 7 digits.

Question 14

For easting and northing it is always…..

Answer 14

Positive number!

Question 15

what geographic coordinate system does NATO use?

Answer 15

Military Grid Reference system

Question 16

Military Grid Reference system degrees.

Answer 16

6 degrees East-West and 8 degrees north-south

Question 17

Regional Reference systems:

Answer 17

1. ) Transverse Mercator
2. ) Universal Polar Stereographic (UPS)
3. ) State plane coordinate system (CLSS)
4. ) Canada Land Survey System (CLSS)
5. ) Public Land Rectangular Survey (USPLS)

Question 18

What regional reference system is used to identify public islands?

Answer 18

Public land rectangular survey

Question 19

Cartesian Coordinates:

Answer 19

Coordinates incidicating location in a space defined by 2 baselines intersecting one another at right angles. The intersection point is the origin for location defined by distances along the 2 intersecting axes.

Question 20

Geodesy;

Answer 20

The science of earths shape and size. Also related to measuring the various gravitational force excerted by earth.

Question 21

Geodetic Datum:

Answer 21

A definition of the size, shape and orientation of the earth; datums support the development of global reference and mapping systems.

Question 22

Geoid:

Answer 22

A model of the earths surface (shape) based on the variable gravitational force exerted by the earth as an object.
