GATE 2023 Geomatics Engineering Syllabus | Download PDF

Updated: Jul 4

In this blog, we have provided the detailed syllabus for the GATE 2023 Geomatics Engineering paper. GATE GE is a new paper being introduced only in 2022. The main topics of this paper include remote sensing, GNSS, GIS and so on as we will see further in this blog. You can also download the syllabus PDF in this blog, so stay till the end.

The GATE exam in general is useful for admissions to post-graduate courses in premium institutes and PSU recruitments. GATE 2023 exam will be conducted by IIT Kanpur probably in the first and second week of February. All details regarding GATE 2023 is already covered in our previous blog.
