Introduction of innovative surveying
systems such as GPS, EDM, digital levels and theodolites, Laser
scanners, digital sensors, high resolution satellite imageries
etc., has revolutionised the scope of spatial data collection.
However, on account of deficiencies in our system of Survey
Education and practices, many of these technologies have yet to
acquire the status of
Broadly, the ethos can be attributed
to two main reasons - the Survey Education, by itself, being not
popular as a discipline of science and there being no regularatory
standards to control the practices of collecting spatial data. A
lot of spatial data being generated by various institutions using
high-end technology by untrained manpower, being inconsistent in
accuracies and unrelated to any meta-data standards on account of
lack of professional supervision, cannot be put to universal use
in a multi-disciplinary environment.
Such efforts, although meeting a limited
requirement, do not contribute to the national need of a standardised
spatial data base and are often found wanting in accuracy when
integrated with a regional or national perspective. For deriving full
benefits and optimising the use of resources, knowledge of the
fundamentals of land surveying and various methodologies of
interfacing them with the new technologies has, therefore, become an
inescapable requirement for all technologists and planners engaged in
generation and manipulation of spatial information.
Survey Education deals with the concepts and methodologies of
gathering, processing and representing geo-spatial data in a defined
form and format. It encompasses education on theories and practices in
disciplines of geodesy, geo-physics, photogrammetry, land surveying,
cartography and reprography. With the introduction of computers and
change of emphasis from analogue to digital technology and high
expectations from GIS, computer sciences and various systems for
generation of spatial data bases have become an integral part of
To keep pace with the present
day requirement of spatial data, education on the modern tools of data
gathering such as
Photogrammetry, laser ranging, remote sensing etc., and associated
technologies in visualization of spatial data, has acquired a special
place in Survey Education. Despite the sophistication in technology,
need-based emphasis on accuracies, reliability and consistency in data
generation remain the cardinal principle in Survey Education.
