Just as a reference ... the geographic coordinates come from dividing the globe into segments as we would an apple, vertical cuts made by meridians (called longitudes) and horizontal cuts made by parallels (called latitudes).

To enumerate the latitudes is part of the equator, north or south from zero to 90 degrees at the poles and these two halves are called hemispheres.

In the case of the lengths, they begin to be enumerated from the meridian of Greenwich called meridian zero towards the east, are enumerated until arriving at 180 degrees, where this same meridian divides the earth (called antemeridiano), to this half it is called " East". Then the other half is called West, generally represented by the W (west), just as the meridians start from Greenwich but in the opposite direction from zero to 180 degrees.

Thus a coordinate in Spain can be Latitude 39 N and length 3 W, a coordinate in Peru would be Latitude 10 S and length 74 W.

This way of determining the coordinates that does not have to do with an altitude above sea level, since it is a vector that starts from the center of the earth towards the surface, this is the projection used by Google Earth, and this is the way of coordinates that use kml files, additionally a reference spheroid is added which is the way to approximate the surface of the earth for measurement purposes. Google uses WGS84 as the reference spheroid (although there are tools that allow UTM coordinates to be entered into Google Earth). The greatest advantage of this projection is that the coordinate is unique on the surface of the earth, although the handling of operations to calculate distances or directions is not practical for "non-geographers".

The UTM coordinates

The UTM coordinates are based on the idea of ​​considering a reference spheroid from the cylindrical projection Traverso de Mercator. The earth is always divided by meridians, in segments of six degrees forming a total of 60, these are called zones. The numbering of these zones is starting from the antemeridian, from zero to 60 from west to east.

The segments that generate the parallels go from the 84 S to the 80 N, and they are enumerated with letters that go from the C to the X (the "I" and the "O" are excluded), each segment has 8 degrees of latitude , except the X that has 12 degrees.

The A, B, Y, Z are used especially for the polar ends; Google does not include this segment because it requires an infinitesimal calculation in an area of ​​interest only for polar bears :).

1 geographic utmIn total 60 zones are 6 degrees each, as well

  • Mexico falls between 11 and 16 zones
  • Honduras in the 16 and part in the 17
  • Peru between 17 and 19
  • Spain between 29 and 31.

The approximation of the reference spheroid at sea level, makes the arc that these lines form have measurements quite similar to the reality of a local measurement. This reference spheroid, previously (popularized in Latin America) was the NAD27, currently the NAD83 is widely used, known by many as WGS84. Having different horizontal reference, the grids of both spheroids are different.

16 zone utmSo an area has an x ​​coordinate, and starting, in the case of Central America, the boundary between the 15 and 16 zones has an approximate coordinate of 178,000 and reaches up to more or less 820,000. This coordinate range is the same for each zone, at the same latitude but we clarify, it is not an orthogonal grid but for purposes of local measurement, it is quite similar. The boundaries between zones are closing, but all part of a central axis, where there is a fully vertical meridian whose length is 300,000 known as "this false", for purposes that both on the left and right of this meridian there are no units negative
The latitude (Y coordinate) starts from 0.00 at the equator and climbs to the north pole with coordinates near 9,300,000.

The maps that we know for cadastral purposes, with scales 1: 10,000 or 1: 1,000 arise from the partition of this zone, in a post next explain how this partition comes.

A geographical coordinate, such as 16N 35W is unique, however a UTM coordinate such as X = 664,235 Y = 1,234,432 equals a point that is repeated in 60 zones at that same latitude, both in the northern hemisphere and in the south; Requires an area and hemisphere to define where it belongs.

  1. Is there any way to calculate the spindle having UTM coordinates?

  2. I have been reading topics on your blog for 4 for some years now. The fact is that I downloaded the UTM zones in GEarth. I have the grid of topographic maps of Nicaragua (those sheets that "measure" 10 ′ of latitude x 15 ′ of longitude. The idea is to take them to GEarth in a similar way to UTM areas. I am not skilled with AutoCAD but rather something with Excel. I tried to solve it like this: In Excel I have the coordinates of the corners of each sheet (obviously not repeated in the neighboring sheets), I made a .txt and with Geotrans I converted them into UTM WGS84 with the idea of ​​taking them to AutoCAD, moving to DXF and then at .kml but my problem is my ability with AutoCAD. Maybe I am taking a great turn, the fact is that I could never draw lines or polygons in GEarth. I would be grateful if you would indicate me any publication of your blog that can help me. Thank you very much from Managua.

  3. Very interesting, later I will need some tutorials, thanks for the information, byee

  4. you're wrong wey that application is already on the google earth

  5. Nothing is downloaded. The link leads to another article. Geofumadas ????
