Easycogo Survey Program for the HP 33s
The Easycogo Survey Program contains simple,
complete descriptions of all individual programs and easy stepbystep RPN mode instructions to enter all of the
programs, which you won't need to do if you purchase the preprogrammed calculator. The
entire Easycogo Survey Program is configured to display simple, obvious, survey
English text messages for each piece of data before the appropriate data input
prompt or output display, so you don't need to remember any obscure codes or
values, as you can see in any of the program demo
videos. Possibilities for application of the included programs are
endless, though a brief summary of the program functionality is as follows:

Menu of all included programs, listed in alphabetical order and
automatically linked to the appropriate program. No more trying to remember
which letter runs the program you need.

Complete
Triangle Solutions for known AngleAngleAngleArea; AngleSideAngle;
SideAngleAngle; SideAngleSide; SideSideAngle; and SideSideSide. All
Triangle sides and angles are displayed, along with the triangle area in
square feet and acres. View Demo

Complete Intersection Solutions including
intersections from two known coordinates by AzimuthAzimuth; AzimuthDistance; and DistanceDistance.
If using bearings, simple bearing to azimuth conversions can be done during
the program with a few extra keystrokes. Coordinates of the intersection
point or points are displayed.

Area By Coordinates for
displaying the area within any coordinated figure bounded by lines. The
perimeter of the figure (or length of traverse) is displayed, along with
the area in square feet and acres. Also useful for determining areas of
figures with curved sides when used with included horizontal curve
calculator, or for finding the top and bottom areas of an odd shaped pond
for easy volume calculation by average end area (a pond volume equation is
available in the Easycogo Survey Equations).

Grades and stations or distances can be used to
determine unknown elevations at any station or distance. Also useful for determining
elevations from crosssection information or interpolating elevations along
any grade from a known elevation.

Horizontal Curve calculator displays
virtually every aspect of the horizontal curve from only a known radius and
either the length of arc or internal angle (delta). Displayed results include the length of arc,
internal angle, tangent,
long chord, PC to PT deflection angle from tangent, mid ordinate, and external ordinate, along with the degree of
curvature (arc definition) and the areas within the sector, fillet and
segment. View Demo

Inverse between known coordinates to display
the bearing, distance and azimuth in the same direction the points are entered.
The included option to "stay" or "move up" also enables easy
traversetype inversing or sideshot type stakeout of any
number of coordinates by inversing a backsight for a
reference azimuth, then inversing desired coordinates for forward azimuth and
distance. Use with included Slope Traverse program for easy inclusion
of elevation
staking.

Leveling tables can be easily completed
by entering the reference mark elevation and successive back and fore rod readings,
having the instrument height and turning point elevations successively
displayed, along with the totals of + and  columns and the elevation
difference from the original reference mark being displayed at each turn for
easy error analysis.

Traverse and Sideshot Horizontally by known bearing or
turned angle (right or left), displaying forward azimuth and coordinates and, if
desired, carry trig levels with the included and integrated Slope Traverse program.
The included option to "stay" or "move up" easily enables
traverse or sideshot type entries.

Traverse Vertically within or without horizontal traverse with the
optionally integrated Slope Traverse program for trig
leveling, including input for reference elevation and instrument and rod height if desired, along with slope
distance and zenith angle, displaying the horizontal distance and foresight point elevation.

Vertical Curve information is easily displayed following input of
basic curve parameters of curve beginning station and elevation, in and out
vertical tangent grades and length of curve. Information displayed includes
the PVT station, PVI station and elevation, K value, high point station if a crest
curve or low point station if a sag curve, followed by a repetitive prompt for
input of any station for display of its oncurve elevation, the initial
default being the high or low point station, as applicable.
View Demo

Volume of cut or fill by roadway station or distance, with the
ability to enter multiple consecutive cross sections for more complex
solutions. The length and volume (cubic feet and cubic yards) of each section
is displayed, along with the accumulated length and volume (also in cubic feet
and cubic yards). (uses average end area formula)
AS IF THAT WASN'T ENOUGH: Much
of the input and resultant data from most of the individual programs will be
automatically saved and displayed for optional use in following appropriate
input prompts within that program and other subsequently executed programs (until revised by
another similar input or calculation), or for easy recall by the displayed
alphabetical storage label, even if the calculator was turned off.
Realworld
example: You used Inverse to determine the azimuth from point 1 to
point 2 before being interrupted by a client. Now you are finally able to
continue the job and decide to begin traversing from point 2 to point 3. Since
point 3 was located by zenith and slope distance, you select the slope traverse
option and enter the appropriate vertical data. You then select the
Traverse Horizontal option, in which the prompt for a backsight reference azimuth will automatically
display the azimuth from yesterday's inverse for optional acceptance and the
prompt for coordinates to traverse from will automatically show the coordinates
of yesterday's input coordinates for point 2. Additionally, the prompt for the
horizontal distance to point 3 will be automatically carried over from Slope
Traverse and displayed for optional acceptance. Continuing the traverse to point
4 will have much of the appropriate information "moved up" for easy acceptance
and continued traversing.

**Since the Easycogo Survey Program requires most (HP35) or all (HP33) of the entire program stack, you will
need to clear it of any program lines, or execute the 'ClearAll' function to
restore it to factory settings. Note that using the 'ClearAll' function will
also clear the equation stack.
***I understand that the programming process is a manual input process that can
be stopped and resumed at any point. I also understand that, not including the
time spent learning to program, it will take at least 4 to 8 hours to completely
input the Easycogo Survey Program, 1 to 2
hours to completely input the Easycogo Survey Equations, and 1 to 2 hours to
completely input the Easycogo HydrologyHydraulics Equations, and though portions of
each will function before completion of the input process, they will not function
completely as indicated until their input process is finished.
