2.0 Consultancy and its products
The most and fundamental question arise in our mind is “what is Survey?”
Survey is the Science of measurement of spatial positions of the features on the
surface of the earth. The purpose of conduction a land survey is to locate the positions of
selected points on or near the surface of the earth.
In simple word, land surveying is the process of demarcating the boundaries, area or
elevations of land or structures on the earth’s surface via taking angle and distance
measurements.
Each of the various kinds of surveys described below is some form of variation of the
above description. We pride ourselves on providing a complete solution to your surveying
needs.
 CADASTRAL SURVEY
Cadastral surveys are used to document land ownership, by the production of
documents, diagrams, sketches, plans, charts, and
maps. They are the surveys that create, mark, define,
retrace, or reestablish the boundaries and
subdivisions of the public lands. Cadastral surveying
is the discipline of land surveying that relates to the
laws of land ownership and the definition of property
boundaries. It involves interpreting and advising on
boundary locations, on the status of land ownership and on the rights, restrictions and
interests in property, as well as the recording of such information for use on plans, maps, etc.

 TOPOGRAPHIC SURVEYS
The purpose of a Topographic Surveys is to gather survey data about the
natural and man-made features of the land, as well as its elevations. From this
information a three- dimensional map may be prepared.
The work usually consists of the following:
 Establishing horizontal and vertical control that will serve as the framework of
the survey
 Determining enough horizontal location
and elevation (usually called side shots) of
ground points to provide enough data for
plotting when the map is prepared
 Locating natural and man-made features that
may be required by the purpose of the survey
Topographical Survey  Computing distances, angles, and
elevations
 Drawing the topographic map Topographic surveys are commonly identified with
horizontal and/or vertical control of third- and lower-order accuracies.
 CONTOUR SURVEY
Contours are an imaginary line connecting the equal height.
Most contour and detail surveys are done by ground survey methods
using electronic total stations and data recorders in much the same
way as the preparation of a topographic map. Commencing from
some known starting points in both horizontal and vertical
dimension, the location of all points which define the terrain and the Contours
structures are recorded. The terrain is often measured using a grid pattern of spot heights.
Most surveyors who have a field capacity undertake contour and detail surveys, either as part
of an overall development project or as a discreet project.

 MINING SURVEY
There are two types of mining (i) Open
Cast Mining and (ii) Underground Mining.
Our experience in Open Cast Mining, we did
survey in mining for pillar marking, contour
marking, detailed survey etc. Mining surveys
may be horizontal, vertical or both and for the
most part (except for possible control surveys)
are plane surveys.

 ROUTE SURVEY
Route surveys establish the location of transportation routes such as:
 Highways and roads
 Railways
 Rapid transit
 Canals
 Pipelines and Transmission lines.
Surveys are required for all types of route alignment, planning, design and construction work.

 LEVEL SURVEY
Drainage systems, both above and below ground, work by creating a slope and relying
on gravity to cause the water (or other liquids) to flow from the high point to the low point.
Unless you have a pumped system the flow of
drainage through the pipeline work will be
dictated by the gradient at which the pipeline
work has been laid. This is known as the fall
and is generally expressed using a ratio i.e.
1:100, which indicates that over a length of
100mm, the pipe will fall 1mm from the high
point to the low point.
Current regulations require standard 100 mm diameter foul drainage pipeline work to
be laid at a minimum fall of 1:80. If the pipeline work is laid below these falls, i.e. at a too flat a
gradient, then disruptions to the flow of drainage are likely to occur which will often cause
blockages within the pipeline. Insufficient falls will often manifest themselves with manholes
or toilets backing up with foul waste.
 CROSS-SECTION SURVEY
Definition:
Cross-sectional research is a research method often used in developmental psychology,
but also utilized in many other areas including social science and education. This type of study
utilizes different groups of people who differ in the variable of interest, but share other
characteristics such as socioeconomic status, educational background, and ethnicity.
For example, researchers studying developmental psychology might select groups of
people who are remarkably similar in most areas, but differ only in age. By doing this, any
differences between groups can presumably be attributed to age differences rather than to
other variables.

Types of Surveys
Data are usually collected through the use of questionnaires, although sometimes
researchers directly interview subjects. Surveys can use qualitative (e.g. ask open-ended
questions) or quantitative (e.g. use forced-choice questions) measures. There are two basic
types of surveys: cross-sectional surveys and longitudinal surveys. Much of the following
information was taken from an excellent book on the subject, called Survey Research Methods.
Cross-Sectional Surveys
Cross-sectional surveys are used to gather information on a population at a single point
in time. An example of a cross sectional survey would be a questionnaire that collects data on
how parents feel about Internet filtering, as of March of 1999. A different cross-sectional
survey questionnaire might try to determine the relationship between two factors, like
religiousness of parents and views on Internet filtering.
Longitudinal Surveys
Longitudinal surveys gather data over a period of time. The researcher may then analyze
changes in the population and attempt to describe and/or explain them. The three main types of
longitudinal surveys are trend studies, cohort studies, and panel studies.
