History and Surveying
History has placed an importance on boundaries, hence theinvolvement of the Surveyor. Whether it be Biblical, Egyptianrope-stretchers, early colonial (U.S.) parcels of land or the
marvel of the foresight of the Public Land Survey System.
On our site, we offer you some details of Ancient LandSurveying, Biblical Quotes about Land and Boundaries,some short examples of Land Surveying in the U.S.(highlighting the Public Land Survey), and assorted links tohelp you on your way of appreciating the rich History of LandSurveying.
Land Surveyors will commonly admit to being History "buffs",due to the nature of their work, which often is termed:
"following in the steps of the original Surveyor". The words"retracement", re-survey and restoration of corners all pointto the nature of the "detective work" of the Land Surveyor,which is always an important factor of the investigation ofboundary issues
History of
Land
Surveying
Ever since ancient man decided that one piece of land would belong to one tribe and another piece of land to
another, theres been a need for land surveys. While the technology and means of mediation have definitely become
more sophisticated over the years, the basic need to define our boundaries remains. Every major civilization in the
history of the world utilized land surveying, some with more sophisticated and accurate results than others.
One of the first examples of surveying by mathematical means was by the Egyptians. The Great Pyramid at Giza,
build around 2700 BC, demonstrates their prowess and knowledge of surveying techniques. When the Nile
overflowed its banks and flooded the plains, the ancient Egyptians redrew boundary lines by using basic geometry.
Also, an Egyptian Land register existed as early as 3000 BC. Though miles ahead of other civilizations of their time in
regards to their surveying and irrigation techniques, nowadays we prefer a much more scientific method of marking
boundaries rather than declaring I swear by the great god that is in heaven that the right boundary stone has been
set up, when the boundary stones were replaced after the flooding waters of the Nile had receded.

Building upon the example of the Egyptians, the Romans went one step further and established Land Surveyor as an
official position within the Roman Empire. They were called agrimensores, collectively known as Corpus
Agrimensorum Romanorum and they performed various tasks throughout the Empire. They were remarkably
thorough and precise in their methodology; they would create straight lines and right angles using simple tools. Once
the lines were measured, they would create a furrow or a shallow ditch to represent the lines. Texts have been found
which date as far back as the first century AD, and some furrows created by them still exist today.
In England in 1086, William the Conqueror wrote the Domesday Book, which covered all of England and contained
the names of the land owners, the amount of land they owned, the quality of said land, and specific information about
each areas resources and peoples. While the breadth of information was impressive for the time, the technical
surveying skills were lacking. The maps were not made to scale and did not accurately show locations.
It should not surprise anyone to learn that Napoleon Bonaparte was enthusiastic about proper surveying. When
youre trying to conquer the known world, it helps to have accurate maps. In 1808 he founded the cadastre, a
comprehensive register of the property of a county, which included ownership details, location as precisely as
possible, and as much information about the value and usage of the land. It also included maps drawn to scale both
at 1:2500 and 1:1250. The usage of the cadastre spread quickly, but ran into problems in the more sparsely
populated and disputed areas, as it needed to be updated every time anything changed. Napoleon felt that the
establishment of the cadastre would be his greatest accomplishment in civil law.
Land surveying has even more applications today than in those of our predecessors. As our means of recording and
preserving our history becomes more sophisticated, so do the means by which we measure and record our
boundaries and land.

Surveying or land surveying is the technique and science of accurately determining theterrestrial or three-dimensional position of points and the distances and angles between them.
These points are usually on the surface of the Earth, and they are often used to establish land
maps and boundaries forownership or governmental purposes.
To accomplish their objective, surveyors use elements ofgeometry, engineering, trigonometry,mathematics,physics, and law.
An alternative definition, per the American Congress on Surveying and Mapping (ACSM), is the
science and art of making all essential measurements to determine the relative position of pointsand/or physical and cultural details above, on, or beneath the surface of the Earth, and to depict
them in a usable form, or to establish the position of points and/or details.
Furthermore, as alluded to above, a particular type of surveying known as "land surveying" (also
per ACSM) is the detailed study or inspection, as by gathering information through observations,measurements in the field, questionnaires, or research of legal instruments, and data analysis inthe support of planning, designing, and establishing of property boundaries. It involves the re-
establishment ofcadastral surveys and land boundaries based on documents of record andhistorical evidence, as well as certifying surveys (as required by statute or local ordinance) of
subdivision plats/maps, registered land surveys, judicial surveys, and space delineation. Landsurveying can include associated services such as mapping and related data accumulation,
construction layout surveys, precision measurements of length, angle, elevation, area, and

volume, as well as horizontal and vertical control surveys, and the analysis and utilization of landsurvey data.
Surveying has been an essential element in the development of the human environment since the
beginning of recorded history (about 5,000 years ago). It is required in the planning and
execution of nearly every form ofconstruction. Its most familiar modern uses are in the fields oftransport,building and construction, communications, mapping, and the definition of legalboundaries for land ownership.

Surveying techniques have existed throughout much of recorded history. In ancient Egypt, whentheNile Riveroverflowed its banks and washed out farm boundaries, boundaries were re-
established by a rope stretcher, or surveyor, through the application of simple geometry. The

nearly perfect squareness and north-south orientation of the Great Pyramid of Giza, built c. 2700BC, affirm the Egyptians' command of surveying.
y The Egyptian land register (3000 BC).
y A recent reassessment ofStonehenge (c.2500 BC) suggests that the monument was set out by
prehistoric surveyors using peg and rope geometry.[1]
y The Groma surveying instrument originated in Mesopotamia (early 1st millennium BC).[2]
y Under the Romans, land surveyors were established as a profession, and they established the
basic measurements under which the Roman Empire was divided, such as a tax register of
conquered lands (300AD).
y The rise of the Caliphate led to extensive surveying throughout theArab Empire.Arabic
surveyors invented a variety of specialized instruments for surveying, including:[3]
o Instruments for accurate leveling: A wooden board with a plumb line and two hooks, an
equilateral triangle with a plumb line and two hooks, and a reed level.
o A rotating alhidade, used for accurate alignment.
o A surveying astrolabe, used for alignment, measuring angles, triangulation, finding the
width of a river, and the distance between two points separated by an impassable
obstruction.y In England, The Domesday Book by William the Conqueror (1086)
o covered all England
o contained names of the land owners, area, land quality, and specific information of the
area's content and inhabitants.
o did not include maps showing exact locations
In the 18th century in Europe triangulation was used to build a hierarchy of networks to allowpoint positioning within a country. Highest in the hierarchy were triangulation networks. These
were densified into networks oftraverses (polygons), into which local mapping surveyingmeasurements, usually with measuring tape, corner prism and the familiar red and white poles,
are tied. For example, in the late 1780s, a team from the Ordnance Survey of Great Britain,originally under General William Roy began the Principal Triangulation of Britain using the
specially built Ramsden theodolite. Large scale surveys are known as geodetic surveys.
y Continental Europe's Cadastre was created in 1808
o founded by Napoleon I (Bonaparte)
o contained numbers of the parcels of land (or just land), land usage, names etc., and
value of the land
o 100 million parcels of land, triangle survey, measurable survey, map scale: 1:2500 and
1:1250
o spread fast around Europe, but faced problems especially in Mediterranean countries,
Balkan, and Eastern Europe due to cadastre upkeep costs and troubles.
A cadastre loses its value if register and maps are not constantly updated. Because of the
fundamental value of land and real estate to the local and global economy, land surveying wasone of the first professions to require Professional Licensure. In many jurisdictions, the land
surveyors license was the first Professional Licensure issued by the state, province, or federalgovernment.

[edit] Surveying techniques
A standard Brunton Geo compass, still used commonly today by geologists and surveyors for field-based
measurements.
Example of modern hardware for surveying (Field-Map technology): GPS, laser rangefinder and field
computer allows surveying as well as cartography (creation of map in real-time) and field data
collection.
Historically, distances were measured using a variety of means, such as with chains having linksof a known length, for instance a Gunter's chain, or measuring tapes made ofsteel orinvar. To
measure horizontal distances, these chains or tapes were pulled taut according to temperature, to
reduce sagging and slack. Additionally, attempts to hold the measuring instrument level wouldbe made. In instances of measuring up a slope, the surveyor might have to "break" (break chain)the measurement- use an increment less than the total length of the chain.
Historically, horizontal angles were measured using a compass, which would provide a magnetic
bearing, from which deflections could be measured. This type of instrument was later improved,with more carefully scribed discs providing better angular resolution, as well as through
mounting telescopes with reticles for more-precise sighting atop the disc (see theodolite).

Additionally, levels and calibrated circles allowing measurement of vertical angles were added,along with verniers for measurement to a fraction of a degreesuch as with a turn-of-the-
century transit.
The simplest method for measuring height is with an altimeter basically abarometer using
air pressure as an indication of height. But surveying requires greater precision. A variety ofmeans, such as precise levels (also known as differential leveling), have been developed to dothis. With precise leveling, a series of measurements between two points are taken using an
instrument and a measuring rod. Differentials in height between the measurements are added andsubtracted in a series to derive the net difference in elevation between the two endpoints of the
series. With the advent of the Global Positioning System (GPS), elevation can also be derivedwith sophisticated satellite receivers, but usually with somewhat less accuracy than with
traditional precise leveling. However, the accuracies may be similar if the traditional levelingwould have to be run over a long distance.
Triangulation is another method of horizontal location made almost obsolete by GPS. With the
triangulation method, distances, elevations and directions between objects at great distance fromone another can be determined. Since the early days of surveying, this was the primary method
of determining accurate positions of objects fortopographic maps of large areas. A surveyor firstneeds to know the horizontal distance between two of the objects. Then the height, distances and
angular position of other objects can be derived, as long as they are visible from one of theoriginal objects. High-accuracy transits or theodolites were used for this work, and angles
between objects were measured repeatedly for increased accuracy.
[edit] Surveying equipment

As late as the 1990s, the basic tools used in planar surveying were a tape measure fordetermining shorter distances, a level to determine height or elevation differences, and atheodolite, set on a tripod, to measure angles (horizontal and vertical), combined with the process
oftriangulation. Starting from a position with known location and elevation, the distance andangles to the unknown point are measured.
A more modern instrument is a total station, which is a theodolite with an electronic distancemeasurement device (EDM). A total station can also be used for leveling when set to the
-
8/6/2019 History and Surveying

horizontal plane. Since their introduction, total stations have made the technological shift frombeing optical-mechanical devices to being fully electronic with an onship computer and software
as well as humans.
Modern top-of-the-line total stations no longer require a reflector or prism (used to return the
light pulses used for distancing) to return distance measurements, are fully robotic, and can evene-mail point data to the office computer and connect to satellite positioning systems, such as aGlobal Positioning System (GPS). Though real-time kinematic GPS systems have increased the
speed of surveying, they are still horizontally accurate to only about 20 mm and verticallyaccurate to about 3040 mm.[4]
Total stations are still used widely, along with other types of surveying instruments. However,
GPS systems do not work well in areas with dense tree cover or constructions. One-personrobotic-guided total stations allow surveyors to gather precise measurements without extra
workers to look through and turn the telescope or record data. A faster but expensive way tomeasure large areas (not details, and no obstacles) is with a helicopter, equipped with a laser
scanner, combined with a GPS to determine the position and elevation of the helicopter. Toincrease precision,beacons are placed on the ground (about 20 km (12 mi) apart). This method
reaches precisions between 540 cm (depending on flight height).[5]
[edit] Types of surveys and applicability
y ALTA/ACSM Survey: a surveying standard jointly proposed by the American Land Title
Association and the American Congress on Surveying and Mapping that incorporates elements
of the boundary survey, mortgage survey, and topographic survey.
y Archaeological survey: used to accurately assess the relationship of archaeological sites in a
landscape or to accurately record finds on an archaeological site.
y
As-built survey: a survey carried out during or immediately after a construction project forrecord, completion evaluation and payment purposes.An as-built survey also known as a 'works
as executed survey' documents the location of the recently constructed elements that are
subject to completion evaluation.As built surveys are typically presented in red or redline and
overlayed over existing design plans for direct comparison with design information.
y Bathymetric survey: a survey carried out to map the topography and features of the bed of an
ocean, lake, river or other body of water.
y Boundary survey: a survey that establishes boundaries of a parcel using its legal description,
which typically involves the setting or restoration of monuments or markers at the corners or
along the lines of the parcel, often in the form ofironrods, pipes, or concrete monuments in the
ground, or nails set in concrete or asphalt.
y Deformation survey: a survey to determine if a structure or object is changing shape or moving.
The three-dimensional positions of specific points on an object are determined, a period of time
is allowed to pass, these positions are then re-measured and calculated, and a comparison
between the two sets of positions is made.
y Engineering surveys: those surveys associated with the engineering design (topographic, layout
and as-built) often requiring geodetic computations beyond normal civil engineering practise.
y Foundation survey: a survey done to collect the positional data on a foundation that has been
poured and is cured. This is done to ensure that the foundation was constructed in the location,
and at the elevation, authorized in theplot plan, site plan, or subdivision plan.

y Geological survey: generic term for a survey conducted for the purpose of recording the
geologically significant features of the area under investigation..
y Hydrographic survey: a survey conducted with the purpose of mapping the coastline and seabed
for navigation, engineering, or resource management purposes.
y Measured survey: a building survey to produce plans of the building. such a survey may be
conducted before renovation works, for commercial purpose, or at end of the construction
process "as built survey"
y Mortgage survey or physical survey: a simple survey that delineates land boundaries and
building locations.In many places a mortgage survey is required by lending institutions as a
precondition for a mortgage loan.
y Soil survey, or soil mapping, is the process of determining the soil types or other properties of
the soil cover over a landscape, and mapping them for others to understand and use.
y Structural survey: a detailed inspection to report upon the physical condition and structural
stability of a building or other structure and to highlight any work needed to maintain it in good
repair.
y Tape survey: this type of survey is the most basic and inexpensive type of land survey. Popular in
the middle part of the 20th century, tape surveys while being accurate for distance lack
substantially in their accuracy of measuring angle and bearing. Standards that are practiced byprofessional land surveyors.
y Topographic survey: a survey that measures the elevation of points on a particular piece of land,
and presents them as contour lines on a plot.

The basic principles of surveying have changed little over the ages, but the tools used bysurveyors have evolved tremendously. Engineering, especially civil engineering, depends heavily
on surveyors.
Whenever there are roads, railways, reservoir, dams, retaining walls,bridges or residential areas
to be built, surveyors are involved. They establish the boundaries of legal descriptions and theboundaries of various lines of political divisions. They also provide advice and data forgeographical information systems (GIS), computer databases that contain data on land features
and boundaries.
Surveyors must have a thorough knowledge ofalgebra, basic calculus, geometry, andtrigonometry. They must also know the laws that deal with surveys,property, and contracts.
In addition, they must be able to use delicate instruments with accuracy and precision. In theUnited States, surveyors and civil engineers use units of feet wherein a survey foot is broken
down into 10ths and 100ths. Many deed descriptions requiring distance calls are often expressed
using these units (125.25 ft). On the subject of accuracy, surveyors are often held to a standard ofone one-hundredth of a foot; about 1/8 inch. Calculation and mapping tolerances are muchsmaller wherein achieving near-perfect closures are desired. Though tolerances such as this will
vary from project to project, in the field and day to day usage beyond a 100th of a foot is oftenimpractical.
In most of the United States, surveying is recognized as a distinct profession apart from
engineering. Licensing requirements vary by state, but they generally have components ofeducation, experience and examinations. In the past, experience gained through an
apprenticeship, together with passing a series of state-administered examinations, was requiredto attain licensure. Now, most states insist upon basic qualification of a degree in surveying, plus
experience and examination requirements.
The licensing process typically follows two phases. First, upon graduation, the candidate may beeligible to take the Fundamentals of Land Surveying exam, to be certified upon passing and
meeting all other requirements as a surveyor in training (SIT). Upon being certified as an SIT,the candidate then needs to gain additional experience to become eligible for the second phase.
That typically consists of the Principles and Practice of Land Surveying exam along with a state-specific examination.

Licensed surveyors usually denote themselves with the letters P.S. (professional surveyor), L.S.(land surveyor), P.L.S. (professional land surveyor), R.L.S. (registered land surveyor), R.P.L.S.
(Registered Professional Land Surveyor), or P.S.M. (professional surveyor and mapper)
following their names, depending upon the dictates of their particular state of registration.
In Canada, land Surveyors are registered to work in their respective province. The designationfor a land surveyor breaks down by province, but follows the rule whereby the first letter
indicates the province, followed by L.S. There is also a designation as a C.L.S. or Canada landssurveyor, who has the authority to work on Canada Lands, which include Indian Reserves,
National Parks, the three territories and offshore lands.
In many Commonwealth countries, the term Chartered Land Surveyor is used for someoneholding a professional license to conduct surveys.
A licensed land surveyor is typically required to sign and seal all plans, the format of which isdictated by their state jurisdiction, which shows their name and registration number. In manystates, when setting boundary corners land surveyors are also required to place survey
monuments bearing their registration numbers, typically in the form of capped iron rods,concrete monuments, or nails with washers.
[edit] Building surveying
Building surveying emerged in the 1970s as a profession in the United Kingdom by a group of
technically minded General Practice Surveyors.[6]
Building surveying is a recognised profession
in Britain, Ireland, Australia and Hong Kong. In Australia in particular, due to risk mitigation
and limitation factors, the employment of surveyors at all levels of the construction industry iswidespread. There are still many countries where it is not widely recognized as a profession.
Building Surveyors are trained to some extent in all aspects of property but with specific training
in Building Pathology, as such they have a wide understanding of the end implications ofdecisions taken by more specific professions and trades during the realisation process, thus
making them ideal Project and Property Managers on the client side.
Services that building surveyors undertake are broad but can include:
y Construction design and building works
y
Project management and monitoringy Property Legislation advice
y Insurance assessment and claims assistance
y Defect investigation and maintenance advice
y Building surveys and measured surveys
y Handling planning applications
y Building inspection to ensure compliance with building regulations
y Pre-acquisition surveys
-

y Negotiating dilapidations claims[7]
Building surveyors also advise on many aspects of construction including:
y design
y
costy maintenance
y sustainability
y repair
y refurbishment
y restoration and preservation of buildings and monuments[8]
Clients of a building surveyor can be the government agencies, businesses and individuals.
Surveyors work closely with architects, planners, quantity surveyors, engineers, homeowners andtenants groups. Building surveyors may also be called to act as an expert witnesses. It is usual for
building surveyors to earn a college degree before undertaking structured training to become amember of a professional organisation.
With the enlargement of the European community, the profession of the building surveyor isbecoming more widely known in other European states, particularly France,
[9]where many
English-speaking people buy second homes.
Lidar Surveying - Three-dimensional laser scanning provides high definition surveying forarchitectural, as-built, and engineering surveys. Recent technological advances make it the most
cost-effective and time-sensitive solution for providing the highest level of detail available forinterior and exterior building work.

The job of the land surveyor is to retrace legal description(s) from the deed belonging to the
subject property by locating actual reference monumentation and verifying its correct position.Over time, development, vandalism and acts of nature often wreak havoc on monuments, so the
land surveyor is often forced to consider other evidence such as fence locations, woodlines,monuments on neighboring property, parole evidence and other evidence.
Reference monumentation refers to actual physical points on the ground that define location ofboundary lines that divide neighboring parcels as well as their respective corners. Also calledsurvey control, they are most often 1/2" or 5/8" iron rebar rods or pipes placed at 18" minimum
depth. These rods and/or pipes usually have an affixed plastic cap over the top bearing theresponsible surveyors' name and license number In addition to rods/pipes, 4x4" concrete posts
are often used at corners of large parcels or anywhere that would require more stability ( ex.beach sand). They are placed at a depth of 3 feet. In places where there is asphalt or concrete, it
is common to place nails or aluminum alloy caps to re-establish boundary corners. Marks should
-

be durable, stable, and as "permanent" as possible. The aim is to provide sufficient marks sosome marks will remain for future re-establishment of boundaries. The material and marking
used on monuments placed to mark boundary corners are often subject to state laws.
F.V. Hayden's map ofYellowstone National Park, 1871. His surveys were a significant factor toward
establishing the park in 1872.
Cadastral land surveyors are licensed by state governments. In the United States, cadastral
surveys are typically conducted by the federal government, specifically through the CadastralSurveys branch of the Bureau of Land Management (BLM), formerly the General Land Office
(GLO).[10]
This includes consultation and boundary determination expertise for USFS, ParkService, Corps of Engineers, BIA, Fish and Wildlife Service, Bureau of Reclamation, etc. In
states that have been subdivided as per the Public Land Survey System (PLSS), the BLMCadastral Surveys are carried out in accordance with that system. This information is required todefine ownership and rights in real property (such as land, water, mineral, easements, rights-of-
way), to resolve boundary disputes between neighbours, and for any subdivision of land,building development, road boundary realignment, etc.
The aim ofcadastral surveys is normally to re-establish and mark the corners of original land
boundaries. The first stage is to research relevant records such as land titles (deeds), easements,survey monumentation (marks on the ground) and any public or private records that provide
relevant data.
In order to properly establish accurate position of survey markers, it is then necessary formeasurements to be taken. This is achieved by placing a [total station] over the points and
recording distances taken with the [EDM].
The data is analysed and comparisons made with existing records to determine evidence that can
be used to establish boundary positions. The bearing and distance of lines between the boundary
-
8/6/2019 History and Surveying
13/24
corners and total station positions are calculated and used to set out and mark the corners in thefield. Checks are made by measuring directly between pegs places using a flexible tape.
Subdivision of land generally requires that the external boundary is re-established and markedusing pegs, and the new internal boundaries are then marked.
[edit] The art of surveying
Many properties have considerable problems with regards to improper bounding, miscalculationsin past surveys, titles, easements, and wildlife crossings. Also many properties are created from
multiple divisions of a larger piece over the course of years, and with every additional divisionthe risk of miscalculation increases. The result can be abutting properties not coinciding with
adjacent parcels, resulting in hiatuses (gaps) and overlaps. The art plays a role when a surveyormust solve a puzzle using pieces that do not exactly fit together. In these cases, the solution is
based upon the surveyor's research and interpretation, along with established procedures forresolving discrepancies.

The Purpose of Land Surveyors in Quantity
Surveys
Quantity surveys determine the volume of soil to be moved.
Quantity surveys are performed most frequently with regard to grading projects. Whether the projectis a new roadway, business development or neighborhood, calculation of the volume of earth to bemoved is instrumental in determining the cost and schedule of a project.
1. Gathering Data
o Quantity surveys begin with a land surveyor gathering topographical data on the tract of landto be developed. The surveyor then plots the gathered data, typically with the use of CADsoftware.
Design Phase
o Once the topographical map is produced, or topo for short, surveyors use this information tocreate a grading plan for the land. Efforts are made during this process to balance the soil asmuch as possible so developers need not bring in extra earth or remove excess from thesite.
Earthwork Quantities
o In the final phase of a quantity survey, the surveyor calculates the final volume of earthexcess or shortage. Even though developers will not need to purchase extra fill soil if anexcess is present, costs are still associated with removal and must be planned foraccordingly

Land and construction surveyors use information differently.
A land surveyor determines distances and angles between points. Construction surveyors setstaking points for the construction of roads and buildings. Land surveying and construction surveyingare two of several surveyor professions.
1. Land Survey
o Land survey is map preparation by working from known points to establish new points. Thistype of survey determines property boundaries to establish ownership. It also definesboundaries and points on public areas. Land surveyors also locate features such as hills,mountains and rivers and use them in their work.
Construction Survey
o
Construction surveyors do a preliminary topographic survey to lay out the general location ofhighway and building construction. After the general positioning, surveyors establish exactlocation points for the construction. They use wooden stakes to guide the construction crews.
General Survey
o Land and construction surveyors use the same instruments and procedures to make theirmaps. The functions of both are to use existing points to establish new points. Each hassimilar goals to establish points, but the final use of this information is different.
