Come ricavare le coordinate UTM?
For practical use, the Google Earth program can display coordinates in UTM and degrees format. To find the "View lat/long" panel, go to Tools and choose "Options". Additionally, you may ask: How can I find the length of a location? Measure. A simplified measure of longitude can be done using a sundial and a clock (or rather, a stopwatch). To determine longitude, you need to read the local time from the sundial and calculate the difference with the clock time, considering that each hour corresponds to 15°.
Finding Latitude of a Place
The magnitude of the angle between the meridian and point P can be used to determine the latitude of a location. This measurement corresponds to the variation of the angle at the center and can range from 0 to 90 degrees, respectively, if P is located on the equator or at a pole.
Calculating Longitude
To calculate longitude, simply find a point on the map and use the numbers to find its coordinates. Specifically, latitude and longitude numbers are positioned to the right and left, while longitude numbers are positioned at the top and bottom.
Using the Sun to Find Latitude
Calculating latitude using the sun goes as follows: You can calculate the sun’s altitude by subtracting or adding the declination of the day from the difference between 90 and the latitude. You can calculate the latitude of a location by measuring the sun’s altitude using the same formula: Latitude will be equal to 90 minus the sun’s altitude, with the daily declination increasing or decreasing.
Using a Stopwatch to Calculate Longitude
For example, if the clock in Greenwich shows 15 and the location is west of Greenwich, it means its longitude is 45° West (15°/hour x 3 hours = 45°).
Length of 1 Degree of Longitude
The modified answer is: The length of the equator is 111.1 km. The distance between the two poles and the equator is the maximum and minimum. One degree of longitude is zero at the pole.
Finding Parallels
Latitude, which is the measurement of the angle between a specific point (taken on its parallel) and the equator, can be defined using parallels. The longitude of a point is the angle between its meridian and the prime meridian of Greenwich. So, how do you calculate the hour angle? The hour angle is the angular displacement of the Sun east or west of the local meridian due to the rotation of the Earth on its axis at 15° per hour, with the morning being negative and the afternoon being positive. For example, at local time 10:30, the hour angle is -22.5°.
Declination of the Sun
Declination of sunlight: It is the angle that the Sun’s rays form with the Earth’s equatorial plane, positive if the Sun is above the plane (graph). The variation ranges from +23°27′ (summer solstice, June 21) to -23°27′ (winter solstice, December 21).
Determining Longitude and Latitude of a Place
Calculated using the map. Subsequently, simply identify the point of interest on the map and use the numbers to find its coordinates. In detail, longitude numbers are at the top and bottom, while latitude numbers are on the right and left.
Using the Sun to Find Latitude
The reassembled answer: The height of the sun can be measured to determine latitude using this formula: Latitude equals 90 minus the height of the sun plus or minus the declination of the day. To determine the height of the Sun, knowing the latitude of the place, you can use the same formula: The position of the sun is equal to 90 degrees with respect to its latitude, plus or minus the declination of the day.
Additionally, people ask: How does the path of the sun in the sky indicate latitude? The rays are at the equator at 90° latitude 0°, while at the North Pole they are tangent at 90° latitude 90° N. At the Arctic Circle, on the other hand, the rays are inclined by 23°27′, which is equal to 90° of the latitude of the place 66°33′ N. This also occurs during the autumn equinox.
