All about Geomatics Engineering (GE)

1. What is GATE?

A national-level entrance examination of India is Graduate Aptitude Test in Engineering or GATE, that generally examine the comprehensive understanding of different undergraduate discipline in Engineering/ Technology/ Architecture/ Science/ Commerce/ Arts/ Humanities for admission to postgraduate programs. The GATE examination was first conducted on 26 February 1983, Saturday by five IITs and IISc Bengaluru with 44 exam centers in different cities in India. The time table of the first GATE 1983 was following-

Last date for issue of Application Forms- 24.12.1982 

Last date for receipt of completed Application Forms- 7.1.1983 

Last date for dispatch of Admit Cards by the respective IIT/IISc -10.2.1983 

G A T E 1983  Exam- 26.2.1983 

Publication of Results of GATE 1983- 15.4.1983

2. Who conduct the GATE?

The GATE is being organized by selected one of eight institutes from IISc Bengaluru and seven IITs (IIT Bombay, IIT Delhi, IIT Guwahati, IIT Kanpur, IIT Kharagpur, IIT Madras and IIT Roorkee), on behalf of the National Coordination Board - GATE, Department of Higher Education, Ministry of Education, Government of India. 

3. Graduate Aptitude Test in Engineering divided into two sections, one is General Aptitude (GA) and candidate selected subjects such as Civil Engineering (CE), Computer Science and Information Technology (CS), Electrical Engineering (EE), Electronics and Communication Engineering (EC), Mechanical Engineering (ME), Metallurgical  Engineering (MT), Mining Engineering (MN), Petroleum Engineering (PE) etc. out of 30 subjects. 

In the year of 2022 two new subject was introduce i.e. Geomatics Engineering (GE) and Naval Architecture and Marine Engineering (NM). 

4. What are the benefits through GATE?

There are several benefits of qualifying the GATE Examination in Geomatics Engineering (GE)-

• It provides secure admission to Masters program in Remote Sensing and GIS, Geoinformatics, Geomatics, Geospatial Science, Geoscience like M.Tech, M.E, M.Sc. and Ph.D. programs in different IITs, NITs and Universities. 
• It gives opportunities for employment in top most multi national companies in the field of Geoinformatics. 
• Also provides an excellent opportunity to apply for different scientific and technical positions in government organizations such as DRDO, BARC, ISRO, and others. 
• It offering Teaching Positions Following the GATE Exam in academic sector. 
• Higher chances of studying for a Master’s degree abroad.

5. General Aptitude (GA): General aptitude is a common and compulsory paper for all the candidates appear in this examination for all the subjects including Geomatics Engineering (GE).

6. Geomatics Engineering (GE):  In the year of 2022 first introduce Geomatics Engineering (GE) as a subject for appearing GATE examination conducted by IIT Kharagpur. In this year 4325 students registered for the examination and appeared 2977. In the year of 2023, 3058 students registered for the examination and appeared 2259. In the year of 2024, 3238 students registered for the examination and appeared 2492.

7. Eligibility Criteria: 

Candidates who are currently studying in the 3rd or higher years of any undergraduate degree program or who have completed any government approved degree program in Engineering/ Technology/ Architecture/ Science/ Commerce/ Arts/ Humanities are eligible to appear for GATE.
