Hyatt Mayor. of departure as latitude, latitude of destination as declination, and difference of longitude as LHA, the tabular altitude and azimuth angle may be extracted and converted to great circle distance and course. As in sight reduction, the tables are entered according to whether the name of the latitude of the point of departure is the same as or.

Demonstrated and illustrated in a plain and familiar manner, by a variety of examples. Together with the construction and use of the table of logarithms. The lines on the plain and Gunter's scales.

Figure shows the effects of the errors in distance and azimuth observations on the computed latitude and departure. In Figure , it can be seen that there is correlation between the latitude and departure; that is, if either distance or azimuth observation changes, it causes changes in both latitude and departure.

LATITUDES AND DEPARTURES: Background. The latitude of a line is its projection on the north-south meridian and is equal to the length of the line times the cosine of its bearing.; The departure of a line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing.; The latitude is the y component of the line (also known as.

Integrated Publishing, Inc. - A (SDVOSB) Service Disabled Veteran Owned Small Business. Computing Latitude and Departure using Azimuth Latitude = D cos Departure = D sin where, D = length of the line; = Azimuth Azimuth angle takes care of lat and dep algebraic sign.

(If we use Bearing for computing lat & dep, we have to pay attention to their signs). 3 Latitudes and Departures of a Closed Traverse For a closed traverse. Departure, and extract the value of D.

Long., or vice versa. The interpolation might be needed to get an accurate result. If the latitude is not the whole number, then repeat the procedure with the table 1° higher, then interpolate two results to get the final answers. Example 7. Long. is ´ and mean latitude is 37°. Find the Departure: 1.

To calculate the latitude and departure of the traverse lines, it is first essential to reduce the bearing in the quadrant system. The signs of latitude and departures will depend upon the reduced bearing of the line. The following table gives signs of latitudes and departures.

Traverse tables: or Tables of difference on latitude and departure: constructed to every quarter of a degree of the quadrant, and to answer for all distances from one tenth of a perch, or mile, to twelve hundred. Particularly suited for the purposes of land surveying.

Latitude and longitude, coordinate system by means of which the position or location of any place on Earth’s surface can be determined and described. Latitude is a measurement of location north or south of the Equator. Longitude is a similar measurement east.

In the latitude column under 15 1/2°, lookup the latitude for 70 feet. You read feet. If the latitude for 70 feet is feet, the latitude for feet is feet. Departure. Latitude. AB 45 45 0 0 Further, the Corrected Readings are calculated to be obtained as per the table.

Question: (b) Table Q3(b) Shows The Adjusted Latitude And Departure For Traverse Line Calculate The Bearing And Distance For All Lines And Plot The Orientation Of Traverse Without Scale. (10 Marks) TABLE Q3(b) Line Adjusted Latitude N S Adjusted Departure E W 1 2 3 4 5 Answer to For the following table determine the corrected latitude and departure.

Also calculate precision ratio. Station AB BC CD. Figure —Latitude and departure. The latitude of a traverse line means the length of the line as projected on the north-to-south meridian running through the point of origin.

The departure of a traverse line means the length of the line as projected on the east-to-west parallel running through the point of origin.

To understand this, you should examine figure Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time is a best-selling book by Dava Sobel about John Harrison, an 18th-century clockmaker who created the first clock (chronometer) sufficiently accurate to be used to determine longitude at sea—an important development in book was made into a television series .Latitudes and Departures from Bearings Latitude is course length times the cosine of the bearing.

Departure is the course length times the sine of the bearing. Append correct signs from the quadrant of the bearing.
