1.1 DEFINITIONS
What is Geomatics?
Derived from two words:
Geo- Matics
Geo- earth
Matics – mathematical
There are many definitions of Geomatics:

Cont’d
• It has been said that geomatics is many
things to many people, but it is generally
accepted as the science and technology of
acquiring and managing information about
our world and its environment. The name
geomatics emerged several years ago in
Canada. The term represents the rapidly
changing and expanding world of land
information management

Definitions of Geomatics on the Web:
• The science and technology of gathering,
analyzing, interpreting, distributing and using
geographical information.

• Geomatics is the discipline of gathering, storing,
processing, and delivering of geographic
information, or spatially referenced information.

Cont’d
• The mathematics of the earth; the science of the
collection, analysis, and interpretation of data, especially
instrumental data, relating to the earth's surface. (Oxford
English Dictionary)
Geomatics Engineering is a modern discipline, which
integrates acquisition, modelling, analysis, and
management of spatially referenced data, i.e. data
identified according to their locations. Based on the
scientific framework of geodesy, it uses terrestrial,
marine, airborne, and satellite-based sensors to acquire
spatial and other data. It includes the process of
transforming spatially referenced data from different
sources into common information systems with welldefined accuracy characteristics.

Cont’d
• Geomatics is the science and technology
of gathering, analyzing, interpreting,
distributing and using geographic
information. Geomatics encompasses a
broad range of disciplines that can be
brought together to create a detailed but
understandable picture of the physical
world and our place in it.
8
Cont’d
• Geomatics is both an applied science and
a professional discipline and it refers to the
integrated approach of measurement,
analysis, management and display of
spatial data. (UCT)
• Geomatics is the science and technology
of land surveying, mapping and spatial
data handling (usually geographical data
about the earth). (UNC)
9
Cont’d
• Geomatics is a scientific discipline which
deals with the measurement, storage,
manipulation, analysis and presentation of
geo-spatial data.
