4.1 INTRODUCTION
Guides to components of surveying which are important for ascertaining cost estimates and
specifying scope of survey works in the planning of any Department of Irrigation and Drainage
project are currently guided by contents in the following references. Updates which are issued from
time to time should be applied where relevant in the future to these references.

4.2 POINT POSITIONING OF A FEATURE USING SATELLITE AND RTK (JADUAL
2001 ITEM 1.4).
The Global Positioning System (GPS) is currently the only fully functional Global Navigation Satellite
System (GNSS). Utilizing a constellation of at least 24 medium Earth Orbit Satellites that transmit
precise microwave radio signals, the system enables a GPS receiver to determine the Position of a
point or location on or above the surface of the earth. The GPS radio receiver has become a widely
used aid to navigation worldwide and a useful tool, among many others, map making and Land
Surveying. GPS equipment used by surveyors incorporates techniques and augmentation methods to
improve accuracy and error sources inherent to operation of GPS. Example of augmentation systems
includes Differential GPS or RTK (Real-Time Kinematic) surveying illustrated at Appendix 3A-1.
In Malaysia RTK survey service for a fee is provided by logging on to myRTKnet located at the
Geodesy Section of the Department of Survey and Mapping.
4.3 PLANIMETRIC (HORIZONTAL TRAVERSING) CONTROL AND CONNECTION
(JADUAL 2001 ITEM 1.5).
Planimetric cntrol and connection is a technique used for determining the relative horizontal positions
(x, y coordinates) of cultural, hydrographic or terrain features for mapping or points needed to plan
and subsequently locate positions or layout accurately bunds, canals, soil investigation boreholes,
roads, waterways and drainage structures, of all kinds. It comprises a series of points on features
surveyed. Hence it comprises:
