This directory contains Ge161 computer programs for summing rotations and rotating data points.

Please copy these executable files to your own directory and run them there.
 Use the ones from the Linux32 directory if you are on 32-bit Linux, and the ones from the Unix directory if you are on Unix.  We do not have versions compiled for 64 bit Linux.

Once you have the files and you are  in your own directory, you need to change the permissions as follows:
chmod +x rotate
chmod +x sumrot
Note that depending on your computer system you may have to call these programs sumrot.exe, rotate.exe, or ./sumrot.exe and ./rotate.exe
So try all of these as needed.
Here are examples of the input and output:

***************

computer%  ./rotate

 This program rotates a point by a given rotation.
 Enter latitude,longitude, and angle of the rotation 
11., 105., 22.
 Enter latitude and longitude of the point to be rotated
44., 67.


 rotation entered                 point entered
 LAT          11.0000                44.0000
 LONG        105.0000                67.0000
 ANGLE        22.0000
 final position of point after rotation is at lat  29.3928,  long   59.1131
  
  
computer% ./sumrot
 This program sums two rotations to give the equivalent rotation.
 Enter latitude,longitude, and angle of rotation number  1
44., 66., 35.
 This program sums two rotations to give the equivalent rotation.
 Enter latitude,longitude, and angle of rotation number  2
12., 24., -9.


**rotations entered**     1          2
           LAT          44.0000      12.0000
           LONG         66.0000      24.0000
           ANGLE        35.0000      -9.0000


 RESULTING POLE            ANGLE


    45.0454    84.4453    29.7353


*****************

NOTE:  BE CAREFUL TO USE LONGITUDE VALUES BETWEEN -180 AND +180 (so
that a longitude of 240 E is entered as -120).

Save these instructions since you may want to use these programs
for future homework assignments.
