This equipment has been tested and found to comply with the limits for a
Class B personal computer and peripherals, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of
the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.

WARNING - This equipment has been certified to comply with
the limits for a Class B personal computer and peripherals,
pursuant to Subpart B of Part 15 of FCC Rules. Only peripherals

to comply with the Class B limits may be attached to this
equipment. Operation with non-certified personal computer
and/or peripherals is likely to result in interference to radio and TV
reception. The connection of a non-shielded equipment interface
cable to this equipment will invalidate the FCC Certification of
this device and may cause interference levels which exceed the
limits established by the FCC for this equipment.
You are cautioned that changes or modifications not expressly
approved by the party responsible for compliance could void your
authority to operate the equipment.

Overview of the Trimble M3 Total Station
Maintenance
Before using the instrument, read and follow the following maintenance instructions:
14
•
Do not leave the instrument in direct sunlight or in a closed vehicle for
prolonged periods. Overheating the instrument may reduce its efficiency.
•
If the Trimble M3 total station has been used in wet conditions, immediately
wipe off any moisture and dry the instrument completely before returning the
instrument to the carrying case. The instrument contains sensitive electronic
assemblies which have been well protected against dust and moisture. However,
if dust or moisture gets into the instrument, severe damage could result.
•
Sudden changes in temperature may cloud the lenses and drastically reduce the
measurable distance, or cause an electrical system failure. If there has been a
sudden change in temperature, leave the instrument in a closed carrying case in
a warm location until the temperature of the instrument returns to room
temperature.
•
Do not store the Trimble M3 total station in hot or humid locations. In
particular, you must store the battery pack in a dry location at a temperature of
less than 30 °C (86 °F). High temperature or excessive humidity can cause mold
to grow on the lenses. It can also cause the electronic assemblies to deteriorate,
and so lead to instrument failure.
•
Store the battery pack with the battery discharged.
•
When storing the instrument in areas subject to extremely low temperatures,
leave the carrying case open.
•
Do not overtighten any of the clamp screws.
•
When adjusting the vertical tangent screws, upper plate tangent screws, or
leveling screws, stay as close as possible to the center of each screw's range. The
center is indicated by a line on the screw. For final adjustment of tangent screws,
rotate the screw clockwise.
•
If the tribrach will not be used for an extended period, lock down the tribrach
clamp knob and tighten its safety screw.
•
Do not use organic solvents (such as ether or paint thinner) to clean the nonmetallic parts of the instrument (such as the keyboard) or the painted or printed
surfaces. Doing so could result in discoloration of the surface, or in peeling of
printed characters. Clean these parts only with a soft cloth or a tissue, lightly
moistened with water or a mild detergent.
•
To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue
that is moistened with alcohol.
Trimble M3 Total Station User Guide

•
The reticle plate cover has been correctly mounted. Do
not release it or subject it to excessive force to make it
watertight.
•
Before attaching the battery pack, check that the contact
surfaces on the battery and instrument are clean. Press
the battery pack into place until the battery mounting
button rises up to the battery pack top surface. If the
battery pack is not attached securely, the instrument is
not watertight.
2
Reticle plate cover
•
Press the cap that covers the data output/external power input connector
terminal until it clicks into place. The instrument is not watertight if the cap is
not attached securely, or when the data output/external power input connector
is used.
•
The carrying case is designed to be watertight, but you should not leave it
exposed to rain for an extended period.
•
The BC-65 battery pack contains a NiMH battery. When disposing of the battery
pack, follow the laws or rules of your municipal waste system. See also
Recycling, page ii.
•
The instrument can be damaged by static electricity from the human body
discharged through the data output/external power input connector. Before
handling the instrument, touch any other conductive material once to remove
static electricity.

Before Going to the Field
Unpacking and packing the instrument
Note – Handle the Trimble M3 total station carefully to protect it from shocks and
excessive vibration.
31.1
Unpacking the instrument
To unpack the instrument, grip the carrying handle and
carefully remove the instrument from the carrying case.
31.2
Packing the instrument
Note – Store the instrument with the battery pack
attached.
To pack the instrument back into the carrying case:
1.
Set the telescope in the horizontal face-1
position.
2.
Align the ∇ storage mark on the bottom of the
face-1 keyboard with the ∇ mark on the tribrach
clamp knob.
3.
Lightly fasten the clamp knobs.
4.
Place the instrument in the carrying case.
Note – When packing the charger (Q-75U/E) in the
plastic carrying case, make sure that you store it as
shown on the sticker inside the case. Make sure that the
battery charger cable is not pinched when you close the
case cover.
3.1
Charging and discharging the battery pack
31.1
Safety notices
Before charging the battery pack, read the following warnings, cautions and notes.
28
C
WARNING – Use only the specified battery charger (part number Q-75U/E) to charge the
battery pack (part number BC-65). Using other chargers, such as a charger with part
number Q-7U/E or Q7C, may cause the battery pack to catch fire or rupture.
C
WARNING – Do not cover the battery charger while the battery pack is being recharged.
The charger must be able to dissipate heat adequately. Coverings such as blankets or
clothing can cause the charger to overheat.
Trimble M3 Total Station User Guide
Before Going to the Field
3
C
WARNING – Avoid recharging the battery pack in humid or dusty places, in direct
sunlight, or near heat sources. Do not recharge the battery pack when it is wet. If you do,
you may receive electric shocks or burns, or the battery pack may overheat or catch fire.
C
WARNING – Although the battery pack (part number BC-65) has an auto-reset circuit
breaker, you should take care not to short circuit the contacts. Short circuits can cause the
battery pack to catch fire or burn you.
C
C
WARNING – Never burn or heat the battery. Doing so may cause the battery to leak or
rupture. A leaking or ruptured battery can cause serious injury.
C
WARNING – The battery BC-65 is not waterproof on its own. Do not get the battery wet
when it is removed from the instrument. If water seeps into the battery, it may cause a
fire or burns.
C
CAUTION – Before charging the battery pack, read the instruction manual for the quick
charger (part number Q-75U/E).
WARNING – Before storing the battery pack or battery charger, cover the contact points
with insulation tape. If you do not cover the contact points, the battery pack or charger
may short circuit, causing fire, burns, or damage to the instrument.
Note – Charge the battery pack indoors where the ambient temperature is between 0 °C
and 40 °C (between 32 °F and 104 °F). If you try to charge the battery when the ambient
temperature is outside this range, the protective circuit will work and prevent it from being
charged normally.
Note – To prevent malfunction, keep the charging plug clean.
Note – If the CHARGE indicator blinks repeatedly after charging starts, there is a problem
with the battery pack. Do not use or charge the battery pack any further, and contact your
dealer.
Note – If the ambient temperature drops below 0 °C (32 °F) while the battery pack is
charging, the charger stops charging the battery pack. When the ambient temperature rises
above 0 °C (32 °F), charging resumes. Charging will be completed after restarting.
Note – If the CHARGE indicator remains lit for more than four hours, and the ambient
temperature during charging was within the specified operational range (0 °C through
40 °C or 32 °F through 104 °F), there is a problem with the battery pack. Do not use or
charge the battery pack any further, and contact your dealer.
Note – During charging or discharging, the battery pack and quick charger will become
warm. This is normal.
Note – After charging the battery pack, do not recharge it until it has been fully discharged.
Recharging a fully charged battery pack lowers its performance.
Note – If the battery pack is used at low temperatures (below -20 °C or -4 °F), its capacity is
reduced, and it will allow less operation time than a battery pack used at normal (room)
temperature.
Trimble M3 Total Station User Guide

Before Going to the Field
Note – If a battery pack is not used for a long period, it cannot be charged to its full
capacity again. To improve the battery pack's capacity, charge and discharge it several
times. See Discharging the battery pack, page 30.
Note – You can use a battery charger with part number Q-70U/E or Q-70C to partially
charge a battery pack with part number BC-65. However, these chargers cannot fully
charge the BC-65 battery pack.
31.2
Charging the battery pack
1.
Connect the power plug on the charger to an AC power outlet.
To AC outlet
Charge indicator
Discharge indicator
Discharge button

Discharging the battery pack
1.
Connect the power plug on the charger to an AC power outlet.
2.
Connect the charging plug on the charger cable to the charging connector on
the battery pack.
3.
Press the Discharge button on the battery charger.
The discharge indicator lights up, and the charger starts to discharge the
battery. When discharging is completed, the discharge indicator turns off. Then
the charge indicator lights up, and charging starts automatically.
4.
To stop discharging the battery pack, press the discharge button again.
Note – The battery pack can be recharged repeatedly. If you recharge the battery pack
while it still has enough power to operate the instrument, however, it will last for a shorter
period. This is called the memory effect. If you experience the memory effect, discharge the
battery pack as described above and then recharge it. This returns the battery pack to its
full capacity. Trimble recommends that you discharge the battery pack in this way at least
once every ten charges.

Setting up the tripod
C
CAUTION – The tops of the tripod ferrules are very sharp. When handling or carrying the
tripod, take care to avoid injuring yourself on the ferrules.
Note – Do not carry the instrument while it is attached to a tripod.
4.1
1.
Open the tripod legs far enough for the instrument to be stable.
2.
Locate the tripod directly over the station point. To check the tripod's position,
look through the center hole in the tripod head.
3.
Firmly press the tripod ferrules into the ground.
4.
Level the top surface of the tripod head.
5.
Securely fasten the thumb screws on the tripod legs.
6.
Place the instrument on the tripod head.
7.
Insert the tripod mounting screw into the center hole of the base plate of the
instrument.
8.
Tighten the tripod mounting screw.
Centering
When you center the instrument, you align its central axis precisely over the station
point. To center the instrument, you can either use the optical plummet or a plumb
bob. The plumb bob is sold separately.
41.1
Centering with optical plummet
Note – If you require high accuracy, check and adjust the optical plummet before you
center the instrument. For detailed instructions, see Checking and adjusting the optical
plummet, page 117.
48
1.
After setting up the instrument on the tripod, look
through the optical plummet and align the reticle with
the station point. To do this, turn the leveling screws
until the center mark of the reticle is directly over the
image of the station point.
2.
While supporting the tripod head with one hand, loosen
the tripod leg clamps and adjust the lengths of the legs
until the air bubble is in the center of the circular level.
3.
Tighten the tripod leg clamps.
4.
Use the plate level to level the instrument. See Leveling, page 49. Look through
the optical plummet to check that the image of the station point is still in the
center of the reticle mark.
Trimble M3 Total Station User Guide
Getting Started in the Field
5.

If the station point is off center, do one of the following:
–
If the station point is slightly off center, loosen the tripod mounting screw
and then center the instrument on the tripod. Use only direct movement to
center the instrument. Do not rotate it.
When the instrument is centered, tighten the mounting screw.
–
4.1
If the displacement of the station point is major, repeat this procedure from
Step 2.
Leveling
When you level the instrument, you make the vertical
axis of the instrument exactly vertical.
To level the instrument, use the plate level.
1.
Loosen the upper plate clamp.
2.
Rotate the alidade until the plate level is parallel
with any two of the leveling screws (B and C).
3.
Use leveling screws B and C to move the bubble
into the center of the level.
4.
Rotate the alidade approximately 90°.
5.
Use leveling screw A to move the bubble into the
center of the level.
6.
Repeat Step 1 through Step 5 to center the bubble
in both positions.
7.
Rotate the alidade 180°.
8.
If the bubble in the plate level remains centered, the instrument is level. If the
bubble moves off center, adjust the plate level. For detailed instructions, see
Checking and adjusting the plate level, page 116.

Focusing the telescope
C
WARNING – Never look at the sun through the telescope. If you do, you may damage or
lose your eyesight.
When you sight the instrument, you aim the telescope at
the target, bring the target image into focus, and align the
image with the center crosshairs of the reticle.
Note – In DR-mode, the center circle of the crosshair is the
beam passing area. The diameter is about 15 cm at 100 m
distance from the instrument.
To sight the instrument:
1.
2.
Adjust the diopter:
a.
Aim the telescope at a blank area, such as the
sky or a piece of paper.
b.
Looking through the eyepiece, rotate the
diopter ring until the reticle crosshairs are in
sharp focus.
Eliminate parallax:
Diopter ring Telescope
focusing ring
a.
Aim the telescope at the target image.
b.
Rotate the focusing ring until the target image is in sharp focus on the
reticle crosshairs.
c.
Move your eye vertically and laterally to check whether the target image
moves relative to the reticle crosshairs.
If the target image does not move, there is no parallax.
d.
3.
50
If the target image does move, rotate the telescope focusing ring. Then
repeat from Step c.
Rotate the tangent screw. The final turn of the tangent screw should be in a
clockwise direction, to align the target accurately on the center crosshairs.

WARNING – The Trimble M3 3” and 5” DR total stations are Class 1 laser instruments. The
laser beam is hazardous to the eyes and the body. Do not sight the instrument on the face
or body of a person. If you suspect an injury caused by exposure to the laser beam, seek
medical advice immediately. If the instrument housing is open and the instrument is
turned on, the laser emits a beam stronger than the Class 1 safety level.
C
WARNING – Observe all other warnings and cautions. See Safety and Warnings, page iii.
The Trimble M3 total station has two measurement modes: Prism mode (Prism) and
Direct Reflex mode (DR). To change the mode at any time from any observation screen,
press
and then press [2]. See also Changing target mode (DR or Prism), page 40.
Table 4.4 describes how to set the measurement mode depending on the target you
want to measure.

Measurement with a prism
As the Trimble M3 total station is extremely sensitive, multiple reflections on the prism
surface can sometimes cause a significant loss in accuracy.
To maintain the accuracy of your measurements:
•
Do not use a prism with scratches, a dirty surface, or a chipped center. Trimble
recommends that you use prisms with thin edges as shown below.
✕
✕
✓
Thin edges
Chipped center
Thick edges
•
When using a reflector sheet, take measurements longer than 5 meters.
•
When using a mini or standard prism, take measurements longer than
10 meters.
Trimble M3 Total Station User Guide
51
4
Getting Started in the Field
•
When measuring a short distance, incline the prism slightly so that the EDM
can ignore unnecessary reflections on the prism surface, as shown below.
Not completely square to
the sighting axis
Completely square to
the sighting axis
Hold the prism securely in place and do not move while taking measurements.
In Prism mode, in order to avoid false measurements on objects other than the prism
or reflector-sheet, targets that are less reflective than the prism or reflector sheet are
not measured. Even if you start a measurement, measured values are not displayed. To
measure less reflective objects, use the Direct-Reflex mode.
41.2
Measurement in Direct-Reflex mode
The intensity of the reflection from the target determines the distance the Trimble M3
total station can measure in this mode. The color and condition of the target surface
also affect the measurable distance, even if the targeted objects are the same. Some
less-reflective targets may not be measured.
Table 4.5 describes some examples of targets and approximate measurable distances.
Table 4.5
Targets and measurement distances
Target
You can measure approximately...
Traffic signs, reflectors
500 meters (1640 feet)
Paper (white), veneer (new)
200 meters (660 feet)
Wall (brightly painted), brick
50 to 100 meters (160 to 330 feet)
Measurable distances may be shorter or measurement intervals may be longer in the
following cases:
•
the angle of the laser against the target is small
•
the surface of the target is wet
In direct sunlight, the measurable distance may be shorter. In this case, try to throw a
shadow on the target.
Targets with completely flat surfaces, such as mirrors, cannot be measured unless the
beam and the target are perpendicular to each other.
52
Trimble M3 Total Station User Guide
Getting Started in the Field

Sighting a prism in Direct-Reflex mode may cause an
excessive signal error. In this case, change the prism
mode to PR - press
and then press [2].
In the Direct-Reflex mode, the beam passing area is
shown by a circle in crosshairs on the telescope reticle.
Beam passing area
If the target is smaller than the circle and there is
something highly reflective in the background, the
measured data may be affected by these adverse
conditions.
When an obstacle momentarily passes through the
beam between the instrument and the target ( for
example, passing cars on the road), the false data (short
distance) is deleted automatically. However, if the amount of reflection is almost the
same and the difference in distances between the correct and the false data is less than
two meters, it may cause an error in measurements.
Make sure there are no obstacles between the instrument and the target when taking
measurements. When you need to take measurements across a road or a place where
vehicles or other objects are frequently moving, take several measurements to a target
for the best result.

Job Manager
The Trimble M3 total station is equipped with an intelligent data management system
called Job Manager. You can record survey data into a folder (a job) and categorize data
by day, by site, or zone-independent.
Up to 32 jobs can be created in the internal memory.
Use the Job Manager to open, create, delete, and manage jobs.
Note – The Trimble M3 total station can also operate without creating a job. In this case,
the system automatically creates a job called NONAME using the current instrument
settings.
To open the Job Manager, select MENU [1].

Setting the Control Point job
Especially for stakeout or station setup work, a Control Point job can be used as an
independent coordinate file when you have a list of coordinate data on your office
computer.
Before you go to the field, upload or input the list of coordinate data to a Control Point
job. See also Uploading data from an office computer to the internal memory, page 113.
In the field, create a working job and set the Control Point job by the process described
below.
If you search for a point when the Control PT job is specified, and the system cannot
find the point in the current job, the Control PT job is also searched. If the point is
found in the Control PT job, it is copied to the current job.
A control job has the same format as a standard job. You can open and modify it like
any other job, and you can use it to record any measured data when you open it as a
current job.
To identify the Control Point file, do the following:
1.

Resection
A resection sets up the station using angle/distance measurements to known points.
If it is not possible to occupy a point with a known position in order to sight the points
to be surveyed or set out, you can carry out a free stationing (or resection). If all
backsight points have a known height, the Z coordinate can be determined
simultaneously.

A maximum of 10 points can be measured. Measurements can be distance and angle,
or angle only. Calculations starts automatically when enough measurements are taken.
At least two sets of distance and angle measurement are required to determine the
station coordinate. After at least two measurements are taken, approximate
coordinates are calculated and residuals are displayed.
You can delete poor observations and recalculate if necessary. You can also select the
backsight (BS) point.
To go to the 3D station setup, press [F1] with. To go to the 2D station setup, press [F3]

Checking and adjusting the optical plummet
The optical axis of the plummet must be aligned with
the vertical axis of the instrument.
To check and adjust the optical plummet:
1.
Place the instrument on the tripod. You do not
have to level the instrument.
2.
Place a thick sheet of paper marked with an X on the ground
below the instrument.
While you are looking through the optical plummet, adjust
the leveling screws until the image of the X is in the center of
the reticle mark.
3.
Rotate the alidade 180°.
P
If the marked image is in the same position in the
center of the reticle mark, no adjustment is required.
4.
If the image is not in the same position,
adjust the optical plummet: Use the supplied
hexagonal wrench to turn the adjustment
screws until the image of the X is in Position
P. Position P is the center point of the line
connecting the X and the center of the reticle
mark.
5.
Repeat from Step 2.

Checking and Adjustment
Checking the instrument constant
The instrument constant is a numerical value used to automatically correct for the
displacement between the mechanical and electrical centers when measuring
distances. The instrument constant is set by the manufacturer before the instrument is
shipped. However, to ensure the highest operational accuracy, we recommend that you
check the instrument constant several times a year.
To check the instrument constant, you can either compare a correctly measured base
line with the distance measured by the EDM, or follow the procedure below.
To check the instrument constant:
1.
Set up the instrument at Point P, in as flat an area as possible.
2.
Set up a reflector prism at Point Q, 100 m away from Point P. Make sure that you
take the prism constant into account.
3.
Measure the distance between Point P and Point Q (PQ).
4.
Install a reflector prism on the tripod at Point P.
5.
Set up another tripod at Point R, on the line between Point P and Point Q.
6.
Transfer the Trimble M3 total station to the tripod at Point R.
7.
Measure the distance from Point R to Point P (RP), and from Point R to Point Q
(RQ).
8.
Compare the value of PQ to the value RP + RQ. The difference should be within
the specified range of error for the instrument (±23 mm + 2 ppm × distance).
At 100 m distance, the error range is ±23.2 mm. If the error is out of range,
contact your dealer.
9.
Move the Trimble M3 total station to other points on the line between Point P
and Point Q.
10. Repeat Step 5 through Step 9 several times.

11. Calculate the average of all the values of RP, and the average of all the values of
RQ.
12. Compare the value of PQ to averaged RP + averaged RQ. The difference should
be within the specified range of error for the instrument (±23 mm + 2 ppm ×
distance).
At 100 m distance, the error range is ±23.2 mm. If the error is out of range,
contact your dealer.

Data Formats
The Trimble M3 total station supports two data formats for downloaded recorded
internal memory data: M5 format and Nikon raw format.
There is also a simple text file format for point number/name list and point code list.
The data output from the Trimble M3 total station can be used with the Trimble Total
Control™ software (TTC), Trimble Geomatics Office™ software (TGO), the
TerraModel® (TM) software, and the Trimble Data Transfer utility.
Trimble surveying instruments are used for measurement functions with different data
processing requirements.
The Trimble M3 total station allows densely packed internal measurement and result
data lines to be output in various formats.
This chapter describes the structure of data format and the type identifier of measured
and calculated values.

B.8
Tip – All instruments have a serial interface which ensures the data exchange.
M5 data format
The point identification in the M5 data format is 27-digit, of which 12 digits are used as
point numbers and 5 digits are used as the point code in the Trimble M3 total station.
The original Zeiss M5 data format is the common standard for the current TTrimble
M3 total stations, the Trimble 3300, and all former Elta® surveying systems.
All five data blocks are preceded by a type identifier. The three numerical data blocks
have a standard layout comprising 14 digits. In addition to the decimal point and sign,
they accept numeric values with the specified number of decimal places.
The information block is defined by 27 characters. It is used for point identification (PI)
and text information ( for example TI).
The address block is comprised of five digits ( from address 1 to 99999).
B8.1
The M5 data line
The data line of the M5 format consists of 121 characters (bytes). The multiplication of
this figure by the number of addresses (lines) stored shows the size of the project file in
bytes.
Blanks are significant characters in the M5 file and must not be deleted.
The example describes an M5 data line at address 176 with coordinates (YXZ)
recorded in unit m. The point identification of marking 1 is DDKS S402 4201. Column
119 includes a blank (no error code).

(columns 18, 19, 20), can be designated to the PI (depending on the instrument).
The type identifier in the M5 Format
Data format requirements have changed and increased over the years. For backwards
compatibility, the M5 Format carries most of the type identifiers of all available
formats, always based on the preceding format (Rec500).
Type identifiers are defined by two characters (except for Adr). If only one character is
necessary, the second character is a blank.
In the M5 Format there are five type identifiers (TK) defined:
•
TK1: Adr Identifier address (Value1)
•
TK2: T2 Identifier information (Value2)
•
TK3: T3 Identifier 3. Value field (Value3)
•
TK4: T4 Identifier 4. Value field (Value4)
•
TK5: T5 Identifier 5. Value field (Value5)
Example: PI for point identification or TI for text information can be used for T2. For
T3, T4, T5, D, Hz, V or Y, X, Z can be used.
The Special characters, page 130 are analogous to the M5 format.
B8.3
Marking in the M5 format
The Trimble M3 total station uses a mark which is saved internally in the instrument.
This mark consists of three blocks with clearly defined block lengths. The user can
change the order of the point number and point code blocks as well as the position of
the information block.

All value blocks are preceded by a type identifier which specifies the function of the
succeeding value.
In the M5 format for the value block there is a unit (dim), which follows the 4-digit
(divided by blanks) value block.
The values are typed right-aligned in the blocks. Decimal point, digits after the comma
and definitions of preceding characters correspond to the internal instrument
specifications.

delta X, delta Y, delta Z
Coordinate differences expressed in the earth-centered Cartesian coordinate
system.
direct reflex (DR)

direction
The angle between a line and an arbitrarily chosen reference line. When the
reference line is north or south and the angle is measured east or west, the

clockwise, the direction is called an azimuth
distance
The (changing) amount of separation between any two points. For example, as
someone moves toward a point, the distance changes.
eccentric measurement
When the target point cannot be measured directly from the station point, you can
use some functions in the "eccentric measurement" program to find a way to
calculate the target point based on the result from alternative measurements.
EDM
Electronic Distance Measurement (telescope part of the instrument).
elevation
The vertical distance from a datum, generally mean sea level, to a point or object
on the earth’s surface. The terms “elevation” and “altitude” have sometimes been
used synonymously, but in modern surveying practice the term “elevation” is
preferred to indicate heights on the earth’s surface whereas “altitude” is used to
indicate the heights of points in space above the earth’s surface.
error
The difference between the measured value of a quantity and its true value.
Surveying errors are generally divided into three categories: blunders, systematic
errors, and random errors. Least squares analysis is used to detect and eliminate
blunders and systematic errors, and least squares adjustment is used to measure
and properly distribute random error.
h
