INTRODUCTION

4. 1.1 DEFINITIONS What is Geomatics? Derived from two words: Geo- Matics
Geo- earth
Matics – mathematical
There are many definitions of Geomatics:

5. 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

6. Cont’d 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. en.wikipedia.org/wiki/Geomatics

7. 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 well-defined accuracy characteristics.

8. 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.

9. 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)

10. Cont’d
Geomatics is a scientific discipline which deals with the measurement, storage, manipulation, analysis and presentation of geo-spatial data.
