How do I represent wind direction on a UTM (Universal Transverse Mercator) map projection?

Asked by: Stacy Wilson

How do you read a Universal Transverse Mercator?

The UTM (Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide. UTM zones are numbered consecutively beginning with Zone 1, which includes the westernmost point of Alaska, and progress eastward to Zone 19, which includes Maine.

How do you present UTM coordinates?

In the case of UTM, I suggest writing “m E” for “meters East” after the Easting, and “m N” for “meters North” after the Northing. When communicating a coordinate by voice, say the words “meters East” after the Easting and “meters North” after the Northing.

How do you draw a UTM projection?

Quote from video: Within a UTM zone a coordinate is defined using easting and northing as opposed to latitude and longitude similarly latitude the northern majors position in the north-south.

What does transverse mean in UTM?

Universal Transverse Mercator (UTM) coordinate system is a standard set of map projections with a central meridian for each six-degree wide UTM zone. The transverse Mercator map projection is an adaptation of the standard Mercator projection which flips the cylinder 90 degrees (transverse).

How do you read UTM coordinates on a map?

These numbers can be found along the left and right sides of the quad map. Always “read RIGHT UP” – find the distance to the EAST, then the distance to the NORTH. Note: since we are in the Northern Hemisphere, we read UTM’s to the “North”. People in the Southern Hemisphere read UTM’s to the “South”.

How do you write UTM location?

For locations north of the equator, give the zone number, the letter “N”, and the distance from the central meridian in meters. For example, Port-au-Prince, Haiti, which is located at lat/long 18.5425*, – 72.3386*, has UTM coordinates of 18N 780950E 2052283N.

How do you write Eastings and Northings?

Quote from video: Point any particular square on the map is labeled by the easting and northing at its bottom left corner the label of the square is the bottom left corner.

What is UTM format?

UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.

How do you read map coordinates?

Latitude and longitude are broken into degrees, minutes, seconds and directions, starting with latitude. For instance, an area with coordinates marked 41° 56′ 54.3732” N, 87° 39′ 19.2024” W would be read as 41 degrees, 56 minutes, 54.3732 seconds north; 87 degrees, 39 minutes, 19.2024 seconds west.

What is Northing and Easting coordinates?

The terms easting and northing are geographic Cartesian coordinates for a point. Easting refers to the eastward-measured distance (or the -coordinate), while northing refers to the northward-measured distance (or the -coordinate). The orthogonal coordinate pair are commonly measured in meters from a horizontal datum.

What units are northing and easting in?

8 digits: the Easting and Northing are each in units of 10m; 10 digits: the Easting and Northing are each in units of 1m.

How do you convert Northing Easting coordinates to longitude and latitude?

Subtract the easting and northing by their respective offset values. (The values will be in meters.) Find the longitude of the given point by finding the destination point given the base point, the absolute value of the easting, and the bearing of 90 degrees if the easting is positive, or 270 degrees if it’s negative.

How do you pronounce UTM coordinates?

Quote from video: If you look here is 310 thousand meters east and basically all that means that is that this grid line is three hundred and ten thousand meters east of my zone twelve meridian.

Can UTM coordinates be negative?

Traditional Universal Transverse Mercator (UTM) convention distinguishes between the Northern and Southern Hemispheres. In the Northern Hemisphere, the UTM zone is a positive value or identified as UTM North. In the Southern Hemisphere, the UTM zone is a negative value or identified as UTM South.

What are the properties of UTM projection?

The UTM uses 60 zones that are 6 degrees wide, with standard central meridians. Within these zones the UTM projection has very little distortion. UTM coordinates can be extended into a neighboring zone for seamless operations, but the farther away from the 6 degree zone you move, the greater the distortion.

How is UTM measured?

In each UTM grid zone, coordinates are measured in meters as “northings” and “eastings”. Northing values are taken by measuring northward from zero (at the equator). Every zone also has a central meridian with an easting value of 500,000 meters.

What is the format of UTM?

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).

Are UTM coordinates projected?

Universal Transverse Mercator (UTM) is a map projection-based global coordinate system that provides location information using pairs of Cartesian coordinates in metric units (metres).

What is the significance of UTM projection?

The UTM projection is designed to create a rectangular cartesian grid. This allows distances and angles to be computed easily, and minimizes distortion. While the military popularized the UTM projection for ground operations, it is also ideal for many GIS operations.

Which are characteristics of the Universal Transverse Mercator UTM system?

The UTM system divides the Earth into 60 zones, each 6° of longitude in width. Zone 1 covers longitude 180° to 174° W; zone numbering increases eastward to zone 60, which covers longitude 174°E to 180°. The polar regions south of 80°S and north of 84°N are excluded.

How do you write Northing and Easting coordinates?

After transformation Latitude is denoted by Y (northing) and Longitude by X (Easting). The most common units of measure in projected coordinate systems are meters and feet. For example UTM is a common projection, a location is identified with easting and northing and the units are in meters.
