Overview

Some information contained within this appendix has been excerpted from the Coast and Geodetic Survey’s (C&GS) publication, Plane Coordinate Projection Tables: “Texas” (Lambert) Special Publication No. 252, and the National Geodetic Surveying (NGS) guidelines and specifications information for latitude and longitude, second term equations.

A very good approximate equation for the second term is:

second term (in seconds of arc) = 2.36 x X x Y x 10-10

where: in feet

in feet

or

second term (seconds of arc) 25.4 E x N x 10-10

where: in meters

in meters

For most surveys the coordinate values for the above equations can be rounded to the nearest 1000 feet or 500 meters.

The magnitude of the second term is small and can be neglected, except for high accuracy surveys with long lines. The table below, listing values for the second term, illustrates this magnitude.

Calculations

Example Problem:

Given: Geodetic Az AB = 110o 27' 32'' 5

= + 3o 01' 39'' 5o

Yo = 596,000 feet

XA = 3,105,000 feet

YA = 205,000 feet

XB = 3,124,000 feet

YB = 198,000 feet



Solution:

= + 19,000

= - 391,000

Anchor: #i1346707 

second term

= 2.36 x (+19,000) x (-391,000) x 10-10

 

= -1'' 8

Grid Az

= 110o 27' 32'' 5

 

= 107o 25' 51'' 2


The second term is usually considered to be an azimuth correction; however, for traverse work it is easier to apply second terms to geodetic angles converting them to grid angles. These grid angles are then used to compute grid azimuths using the normal traverse calculation procedures.
