Understanding the GE Paper Structure
The GATE GE paper allows candidates to tailor the exam to their strengths. The paper is split into three compulsory parts and one elective section:
• General Aptitude (Compulsory): 15 Marks.
• Part A (Compulsory): 55 Marks. Covers Engineering Mathematics and Basic Geomatics (RS, GIS, GNSS).
• Part B (Elective): 30 Marks. Candidates choose either Section I or Section II during the exam.
Major Marks Distribution
Since Part A carries 55% of the technical marks, it is the most critical area for ensuring a qualifying score.

Part A: Core Technical Foundations
This section tests your baseline knowledge in geospatial technologies. High-priority topics include:
1. Remote Sensing: Electromagnetic spectrum, sensors (active vs passive), and spectral signatures.
2. GIS (Geographic Information Systems): Data models (vector/raster), spatial analysis (buffering, overlay), and DBMS.
3. GNSS: Principles of GPS, GLONASS, Galileo, and error sources in satellite positioning.
4. Engineering Mathematics: Linear algebra, calculus, and surveying error adjustments (Least Squares).
Part B: Surveying vs. Image Processing
During the 3-hour window, you must choose one of the following specializations based on your background:
Section I: Surveying and Mapping – Best for Civil Engineering students. Focuses on Land Surveying (Total Station, Theodolite), Aerial Photogrammetry (Stereoscopy, DEM), and Map Projections.
Section II: Image Processing and Analysis – Best for CS/IT/Electronics students. Focuses on Digital Image Processing (Histograms, Filters), Image Enhancement, and Transformations (PCA, NDVI).
Top Success Strategies
1. Zero-Error in Math Adjustments: Questions on "Most Probable Value" and error adjustments in Part A are scoring but require precise calculation.
2. Understand Resolutions: Spatial, Spectral, Radiometric, and Temporal resolutions are the backbone of Remote Sensing questions.
3. Virtual Calculator Practice: Use the official tool for Photogrammetry height determinations and Parallax calculations.
4. Choice Clarity: Decide whether you will attempt B1 or B2 before the exam based on previous year papers (2022-2025).
