NAME

- -geod - direct geodesic computations -
- -invgeod - inverse geodesic computations - -

SYNOPSIS

- -geod - -+ellps=<ellipse> - -[ --afFIlptwW - -[ -args - -] ] [ -+args - -] -file[s] -
- -invgeod - -+ellps=<ellipse> - -[ --afFIlptwW - -[ -args - -] ] [ -+args - -] -file[s] - -

DESCRIPTION

- -Geod - -(direct) and -invgeod - -(inverse) -perform geodesic (``Great Circle'') computations for determining -latitude, longitude and back azimuth of a terminus point -given a initial point latitude, longitude, azimuth and distance (direct) or -the forward and back azimuths and distance between an initial and -terminus point latitudes and longitudes (inverse). -

- -The following runline control parameters can appear in any order: -

-I - -: -Specifies that the inverse geodesic computation is to be performed. -May be used with execution of -goed - -as an alternative to -invgeod - -execution. -
-a - -: -Latitude and longitudes of the initial and terminal points, -forward and back azimuths and distance are output. -
-ta - -: -A - -specifies a character employed as the first character to denote -a control line to be passed through without processing. -
-le - -: -Gives a listing of all the ellipsoids that may be selected with the -+ellps= - -option. -
-lu - -: -Gives a listing of all the units that may be selected with the -+units= - -option. -
-[f|F] format - -: -Format - -is a -printf - -format string to control the output form of the geographic coordinate values -(f) or distance value (F). -The default mode is DMS for geographic coordinates and "%.3f" for distance. -
-[w|W]n - -: -N - -is the number of significant fractional digits to employ for -seconds output (when the option is not specified, --w3 - -is assumed). -When --W - -is employed the fields will be constant width with leading zeroes. -
-p - -: -This option causes the azimuthal values to be output as unsigned -DMS numbers between 0 and 360 degrees. Also note -f. -

- -The -+args - -run-line arguments are associated with geodetic parameters -for specifying the ellipsoidal or sphere to use. -See -proj - -documentation for full list of these parameters and contrl. -The options are processed in left to right order -from the run line. -Reentry of an option is ignored with the first occurrence assumed to -be the desired value. -

- -One or more -files - -(processed in left to right order) -specify the source of data to be transformed. -A - will specify the location of processing standard input. -If no files are specified, the input is assumed to be from -stdin. - -

- -For direct determinations input data must be in latitude, -longitude, azimuth and distance order and output will be -latitude, longitude and back azimuth of the terminus point. -Latitude, longitude of the initial and terminus point are -input for the inverse mode and respective forward and back -azimuth from the initial and terminus points are output along -with the distance between the points. -

- -Input geographic coordinates -(latitude and longitude) and azimuthal data must be in DMS format and input -distance data must be in units consistent with the ellipsoid -major axis or sphere radius units. -Output geographic coordinates will be in DMS -(if the --f - -switch is not employed) to 0.001" -with trailing, zero-valued minute-second fields deleted. -Output distance data will be in the same units as the ellipsoid or -sphere radius. -

- -The Earth's ellipsoidal figure may be selected in the same -manner as program -proj - -by using -+ellps=, +a=, +es=, - -etc. -

- -Geod - -may also be used to determine intermediate points along either -a geodesic line between two points or along an arc of specified distance -from a geographic point. -In both cases an initial point must be specified with -+lat_1=lat - -and -+lon_1=lon - -parameters and either a terminus point -+lat_2=lat - -and -+lon_2=lon - -or a distance and azimuth from the initial point with -+S=distance - -and -+A=azimuth - -must be specified. -

- -If points along a geodesic are to be determined then either -+n_S=integer - -specifying the number of intermediate points and/or -+del_S=distance - -specifying the incremental distance between points must be specified. -

- -To determine points along an arc equidistant from the initial point both -+del_A=angle - -and -+n_A=integer - -must be specified which determine the respective angular increments -and number of points to be determined. - - -

EXAMPLE

- -The following script determines the geodesic azimuths and distance in -U.S. stature miles from Boston, MA, to Portland, OR: -

: -
geod +ellps=clrk66 <<EOF -I +units=us-mi - 42d15'N 71d07'W 45d31'N 123d41'W - EOF -

- -which gives the results: -

: -
-66d31'50.141" 75d39'13.083" 2587.504 -

- -where the first two values are the -azimuth from Boston to Portland, the back azimuth from Portland to -Boston followed by the distance. - - -An example of forward geodesic use is to use the Boston location and determine -Portland's location by azimuth and distance: -

: - geod +ellps=clrk66 <<EOF +units=us-mi - 42d15'N 71d07'W -66d31'50.141" 2587.504 - EOF -

- -which gives: -

: -
45d31'0.003"N 123d40'59.985"W 75d39'13.094" -

- -Note: lack of precision in the distance value compromises -the precision of the Portland location. - -
