In general the easting values can not be larger than 834000m and smaller than 166000m. In contrast, in the geographic coordinate system the distance represented by one degree (or minute or second) of longitude varies with latitude, therefore the units of measure do not remain constant across the globe. There’s a few common misconceptions in this post that always need to be unlearned by students and practitioners. However, there are exemptions, where dimensions of some zones are adjusted.

In the southern hemisphere, the equator starts at 10,000,000 meters. Transverse Mercator would keep the horizontal cylinder but have earth poles oriented up & down, as in the diagram before that one.UTM system, because of the distortions in each zone, with movement away from the central merdian seems to be of limited use for cadastral and engineering surveying.It is already known that it is not intended for small-scale mapping.Why then is it being used by surveyors and allied specialists, while there are other projections -conical, orthogonal- and others.How can we minimize the distortion of shape, area, distance and direction in UTM???

This means that a distance of 100 meters on an ellipsoid would be 99.96 meters on a map.If you’re in the northern hemisphere, the equator has a northing value of 0 meters. UTM is not suitable for areas that span more than a few zones since distortion and error increases when moving farther from the zone for which the projection is defined. To find the easting of point A, value of the nearest grid line to the left (west) of the point is found. The distance between the above points is 500008 – 499650 = 358m.Longitude lines are furthest apart at the equator, where latitude is zero. The datum is printed on the margin of topographic maps, sometimes along with information for conversion of coordinates between two different datums by addition to or subtraction from northing and easting values; such as the example to the right.UTM gridlines are usually shown on the map, or ticks are marked on the margins of the map. Draw … In a conformal projection local angles are preserved and shapes are represented accurately and without distortion for small areas. Consequently, the distortion pattern created by each includes a swath of deflation between the standard circles, no distortion along the standard circles (scale factor = 1.0), and inflation beyond them.Download our lakes and rivers map of the United States. Letters A, B, Y and Z label polar regions in the UPS coordinate system. In the southern hemisphere the northing values range from 10,000,000m at the equator to approximately 1100000m at the 80th south parallel. Or select from any of the 50 states for detailed lakes and rivers. It is possible to define a location within 1000m, 100m, or 1m.

The data for this map comes from the U.N. Population Division, more information on how it was calculated at the bottom of the post.. Full screen version / Youtube video. Coordinates are always positive and there is no need for N, E, W, S designations. The complete UTM coordinate is: Zone 10U 5For a more accurate way of reading or plotting UTM coordinates on maps some tools such as UTM Therefore a point lying in the first quadrant, to the right of y-axis and above x-axis, has positive x and y coordinate values.In contrast to the projected coordinate system, the The vertical direction of grid lines is referred to as Designation of the central meridian as the reference y-axis (i.e. Within a zone, easting values increase towards east. A complete UTM coordinate including all the digits, such as 12S 565234mE 4325782mN, specifies the location of a point within a 1m by 1m square. Distortion is small near the central meridian, and as you move away it worsens. In the northern hemisphere the northing values stretch from 0m at the equator to around 9350000m at the 84th north parallel. The grid is labeled with UTM coordinate values. Letters I and O are omitted to prevent confusion with numbers one and zero. These suffice to find locations on the map. Satellite Map of USA – United States of America Therefore the maximum width of a UTM zone occurs on the equator. …

Thank youYes.

The datum or reference ellipsoid is WGS 84 (World Geodetic System 1984). So this makes it Just like every map projection, the Universal Transverse Mercator has its strength and weaknesses. The UTM projection flattens the sphere 60 times by shifting the cylinder central meridian …

1 billion. Look along the bottom edge of the map at the labels for the vertical grid lines. The easting of a point 350m west of central meridian would be 500000 – 350 = 499650mE.

The transverse Mercator map projection is an adaptation of the standard Mercator projection which flips the cylinder 90 degrees (transverse).The UTM projection flattens the sphere 60 times by shifting the cylinder central meridian 6° for each zone. On the other hand smaller scale Canadian NTS 1:250000 and USGS 1:100000 and 1:250000 scale maps show gridlines at 10000m (10 km) intervals. It’s the Universal Transverse Mercator (UTM) projection! Printed UTM Grid Lines. 120 zones means 120 map projections.Second, each instance of the transverse Mercator projection method used in this system is a secant type of projection (scale factor along the central meridian < 1.0) and not a tangent type (as illustrated above). The east-west distance between two points is obtained by the difference of their easting values.

A The intersection of the x and y axes in the rectangular coordinate system divides the space into four quadrants. The scale error within each UTM projection zone remains less than 0.1 percent, or in other words scale distortion is kept to less than 1 part in 1000. Sometimes in guidebooks UTM coordinates are provided in an abbreviated format. Note that there are a few exceptions to zone width in Northern Europe to … At places on map where the cylinder is outside the globe, features appear larger than in reality and scale factor is greater than 1. Then, peel it like an orange evenly into sixty segments called “zones”. Create stories and maps. If you’re not familiar with Godwin’s law, it is an old internet adage that states, “As an online discussion grows longer, the probability of a comparison involving Nazism or Hitler approaches 1.. …
