Compute station to station azimuth and distance

I N D I R :

This program can use the azimuth and distance from a known point to compute a new point (Geographic direct) or can use the geographic coordinates of two points to compute the azimuth and distance between them (Geographic inverse).

Other options allow the user to list coordinates, compute stations that are within a given radius and compute a station coordinate given observations of direction, distance and/or azimuth.

The user can list the output to the terminal and/or to a file.

The user can choose from a menu a number of available options.

First the user is asked to Choose an Ellipsoid.

Next the user is asked for a screen listing and or capture the output to a file

 Listed on the screen [CR][Y]

 Listed to a file [Y]

To get started the user has 3 options available.

The user can now choose to enter some coordinates, do a direct solution or do a station solution. When coordinates are input other options become available.

Input coordinates [I] <== User can enter coordinates from the terminal or from a file
Direct computation [D] <== User can use azimuth and distance to compute coordinates
Station solution [S] <== User can use combinations of angles, distances and azimuths to compute station coordinates
```
 Quit            [CR][Q] <== Exits the program   
```

After coordinates are input the program has an Expanded menu

[I] Input coordinates

  =================

Most of the program options require an initial set of coordinates. This menu allows the user to read GHOST coordinate records into the program.

Station coordinates

List station names [L]
Enter coordinates from terminal [T]
Enter coordinates from file [F]
Quit [CR][Q]

[T] Enter coordinates from the terminal

(the program will prompt for input)

Back

[F] Input coordinates from a file.

The program will prompt for a file name. It will then look for any Ghost coordinate records in the file and neglect anything else encountered.

[V] Compute inverse computations

The inverse computation is the azimuth and distance between two known coordinates

>p> The user can chooe to save the output to a file.

The inverse computations can be done as

Geodesic inverse [G]
Normal section inverse [N]
XYZ slope [X]

The Inverse computations can be done either as a complete set of inverse computations (N*N combinations) or as individual pairs of stations.

The first option is to do the inverses one at a time and allow the user to monitor each inverse.

If desired the monitoring can be vetoed by choosing the option [N]
