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.

### Syllabus Overview

Broadly speaking, the Geomatics engineering paper consists of the following subjects.

• Engineering Mathematics

• Remote Sensing

• GNSS

• GIS

• Maps

• Land surveying

• Aerial Photogrammetry

• Data Quantization and Processing

• Digital Image Processing

• Image Enhancement

• Image Transformation

• Image Sensation and Classification

The aptitude syllabus is the same for every paper. It covers 15 marks out of the total 100 marks.

### Aptitude Syllabus

Verbal Aptitude

• Basic English grammar: tenses, articles, adjectives, prepositions, conjunctions, verb-noun agreement, and other parts of speech

• Basic vocabulary: words, idioms, and phrases in context Reading and comprehension Narrative sequencing

Quantitative Aptitude

• Data interpretation: data graphs (bar graphs, pie charts, and other graphs representing data), 2- and 3-dimensional plots, maps, and tables

• Numerical computation and estimation: ratios, percentages, powers, exponents and logarithms, permutations and combinations, and series Mensuration and geometry Elementary statistics and probability

Analytical Aptitude

• Logic: deduction and induction, Analogy, Numerical relations and reasoning

Spatial Aptitude

• Transformation of shapes: translation, rotation, scaling, mirroring, assembling, and grouping

• Paper folding, cutting, and patterns in 2 and 3 dimensions

### Detailed Syllabus

Overall syllabus just gives an idea about what are all the subjects present. But it is important to know topics and sub-topics within each subject to get a clear idea of the task at hand. And the same is provided below.

### Who can write GATE GE as the second paper?

GATE 2021 introduced the option to write two GATE papers in the same year and the same will be continued for all the upcoming GATE exams. But there are certain paper combinations to follow, which we have covered in our GATE 2023 blog. Here we provide the detail of which papers are eligible as the first paper for writing GE as the second paper.

• Agricultural Engineering (AG)

• Architecture and Planning (AR)

• Environmental Science and Engineering (ES)

• Civil Engineering (CE)

• Electronics and Communication Engineering (EC)

• Computer Science and Information Technology (CS)

• Naval Architecture and Marine Engineering (NM)

• Mathematics (MA)

• Mining Engineering (MN)

• Physics (PH)
