Traverse v1.0        Azimuth v2.0        LatDep v1.1
                        By: David Shafer

Welcome to my latest programs for the HP 48 series calculators.  All of these programs accept
angles in DMS and return angular values in DMS. 

Traverse.  This program is a an easy to use user RPL program that computes a closed traverse by
Latitudes and Departures, it then is capable of adjusting the Latitudes and Departures by the
Compass rule.  The program will also compute the area of your parcel in acres and give
coordinates for your traverse points. (Size needed 4 kbytes for the program + 80 bytes per leg in
the traverse)

Azimuth.  This program removes need for need of tedious calculations when making
calculations of the sun's azimuth by the altitude method.  (Size needed 1.5 kbytes + 200 bytes of
temporary storage space)  

LatDep.  This program calculates the Latitudes and Departures of a single line. (I used this
program's code in Traverse)  (Size 600 bytes)

What to do:
     Install the program to your calculator either from a friends calculator or from your PC
with an uplink cable.  If you are looking for a good HP - PC program get a freeware copy of
HPSHELL v3.0 from ftp.cis.com/pub/hp48/uploads/HPS300a.zip.  Because my programs are
written in user RPL (which means they are a little slower)  the calculator performs the error
checking and therefore your shouldn't need to worry about backing up your calculators RAM,
but it is always a good idea.

Using TRAVERSE:
     Needed data: Point NUMBERS (letters or Alpha-Numeric won't work) Angle of the lines
     in Bearing or Azimuth form and the distance of the line and the total number of legs in   the traverse.
     1.  Press the softkey that says TRAVE
     2.  Press ENTER after the message box comes up.
     3.  Enter the number of legs in your traverse.
     4.  Follow the on screen prompts, it is very self explanatory
     5.  After you enter all of your traverse data the program will begin to show information       on the screen, after you have seen this information press enter to goto the next screen 
     6.  NOTE: before finding area or viewing the coordinates and balanced lats & deps you          need to adjust your traverse.
     7.  NOTE: This program is set up not to erase its data file named TDAT after use, which        means if your want to see what you entered you can bring up the matrix TDAT and           place it in the HP matrix viewer.

Using LATDEP:
     Needed data:  Angle of line in Bearing or Azimuth and the distance of the line
     1.  Press the softkey that says LATDE
     2.  Follow the on screen instructions
     
Using AZIMUTH:
     Needed data: Declination on the date of and the date after the observation at 0 hr GMT,   the GMT of the observation, The latitude of the place of observation, the size and type of
     angle Vertical or Zenith, The temperature and pressure or elevation (only if you are      correcting for refraction)
     1.  Press the softkey that says AZIMU
     2.  Follow the screen prompts 
     NOTE: This program will give you the correct value for the azimuth in DMS, but  remember is your observations were in the afternoon / evening then you need to subtract   that value from 360 degrees

What do they cost:
     Nothing - it is shareware, but If you want to send $5 then I will send you the latest
versions, be more responsive to your problems, and maybe even write a program that you need
for a little more $.
