58 ANGULAR SURVEYING 



EXAMPLE. Plat by latitudes and longitudes the field to 

 which the following notes refer; the reference meridian and 

 parallel pass through the corner A. 



Courses Latitude Ranges Longitude Ranges 



A B + 48.27 - 41.73 



B C + 17.66 - 37.18 



CD - 30.25 - 14.92 



DE -106.67 +121.17 



E F + 96.49 + 75.85 



FA - 25.50 -103.19 



SOLUTION. The operations and results are indicated by 

 the following arrangement, in which Lat. stands for latitude 

 and R. for range: 



Latitudes 



Lat. R. of AB= + 48.27 = Lat. of B 

 Lat. R. of BC= + 1 7.66 



+ 65.93 = Lat. of C 

 Lat. R. of CD= - 30.25 



+ 3 5.6 8 = Lat. of D 

 Lat. R. of DE 106.67 



- 7 0.9 9 = Lat. of E 

 Lat. R. of EF= + 96.49 



+ 2 5.5 = Lat. of F 

 Lat. R. of FA = - 25.50 



0.0 = Lat. of A 

 Longitudes 



Long. R. of A B = - 4 1.7 3 = Long, of B 

 Long. R. of BC = - 37.18 



- 7 8.9 1 = Long, of C 

 Long. R. of CD = - 14.92 



- 9 3.8 3 = Long, of D 

 Long. R. of DE = + 121.17 



+ 2 7.3 4 = Long, of E 

 Long. R. of EF = + 75.85 



+ 1 3.1 9 = Long, of F 

 Long. R. of FA - - 103.19 



0.0 = Long, of .4
