RECORDER

• Duty is to keep a record of all sketches, drawings, measurements and observations taken or needed for a field work operation • Keeps table of schedules of all phases of work and the employment of the members of the survey party

FLAGMAN

• Duty is to hold the flagpole or range pole at selected points as directed by the instrument man • Helps the tapeman in making measurements and assists the axeman in clearing other obstructions to line of sight • Responsible for setting up reflectors, targets, prisms

HEAD AND REAR TAPEMAN

• Responsible for the accuracy and speed of all linear measurements with tape • Determines and directs the marking of stations to be occupied by the surveying instrument and directs the clearing out of obstructions along the line of sight • Inspects and compares tapes of standard length prior to their use in taping operation and is responsible for eliminating or reducing possible errors and mistakes in taping

RODMAN

FLEXIBLE

When organizing a survey party, be __________

FIXED

Duties and responsibilities of members should always be ________

Make modifications to suit:

❑ Work requirements and conditions

❑ Problems in field operations

❑ Availability of instruments

Field Notes

❑Constitute the only reliable and permanent record of actual work done in the field

❑If notes are incorrect or incompletely done time, money and effort in data gathering are wasted

❑Field notes become the official record of the survey

Types of Field Notes

Sketches

Tabulations

Explanatory Notes

Calculations

Information Found in Field Notes

Title of Project/Fieldwork

Date and Time

Weather Condition

Survey Party Designations

List of Equipment and Accessories Used

Guide Points in Note-keeping

Follow a consistent simple style of writing

Record directly in the field book immediately following a measurement, rather than on a sheet of scratch paper for copying

Use sharp pencil Do not erase recorded data.

For an erroneous entry, a line is run through it and the correct value is written above the mistake

Guide Points in Note-keeping

If entire page is to be deleted, diagonal lines are drawn from opposite corners and “VOID” is lettered prominently

Avoid crowding observed data in the field notebook

Always bring along a straight edge for ruling lines, and a small protractor for laying off angles in the field book

To avoid misinterpretation of data, use sketches other than tabulations.

Use also explanatory notes.

Guide Points in Note-keeping

Indicate north at the top of the page of the field notebook for all sketches shown in plan and draw a meridian arrow

Tabulated values should be kept inside the column rulings, with the decimal point and digits aligned vertically.

Check the computations while on the field to know if there are necessary observations that should be repeated

Number every page of the field notebook

RADIOS (TWO-WAY RADIO)

used extensively, because they are relatively inexpensive, and provide an efficient means of communication within a survey party.

HAND SIGNALS

more efficient means of communication than is possible by word of mouth.

Any code of signals mutually understood by the persons handling the instrument and the rod is good if it works

TRANSIT

“Universal Surveying Instrument”

❑ primarily used for measurement or layout of horizontal and vertical angles

❑ also used to determine vertical and horizontal distance by stadia and low order leveling

THEODOLITE

❑ a precision instrument used for measuring angles both horizontally and vertically

❑ angular measurements are more accurate than transits

TOTAL STATION

an electronic transit and an Electronic Distance Measurement (EDM) device combined into one instrument

LEVEL

an instrument used to measure elevations of points and differences in elevation between points based on a reference benchmark

Care and Handling of Instruments

Know how to use the instrument

Always place them in stable grounds when in use

Place them properly in their container

Do not use them if weather does not permit

Check their functionality before and after field work

Care and Handling of Instruments

If wet, dry them by carefully wiping excess water and do not put them immediately in their storage/container

Carry the instrument properly

Be mindful of the surroundings when transporting any equipment

Avoid playing with the instrument

Always make sure that the equipment is secure
