BGGCT 133 Solved Question Paper June 2026 answers IGNOU's General Cartography paper, the core geography course of the Bachelor of Science (General) that teaches how maps are scaled, projected, sourced and drawn.
1. What the June 2026 Solved Paper Covers
We took the official June 2026 term-end paper and had our geography team write a full answer for every question printed in it, 24 in all, counting both choices of each Section C question. The answers follow the length and structure IGNOU examiners expect, with the sketches the paper asks for.
This June paper leans on old favourites. Map scale, Mercator's projection, Census of India series and contour drawings all came back, and there were two surprises: an opto-mechanical scanner question in place of the usual pushbroom one, and a hythergraph instead of the climograph or ergograph students had prepared.
On this page you can read two answers in full, see every other question exactly as printed, and check which blocks and topics each one comes from.
2. Two Answers Solved in Full, Twenty-Two Held Back
Two BGGCT 133 June 2026 answers are shown in full below, Q2(iv) on the electromagnetic spectrum and Q3 on map scale; the other 22 questions are listed as printed and answered only in the full file.
We picked one Section B answer and one Section C answer so you can judge both lengths. Question text is copied exactly from the official paper, including its own numbering.
The electromagnetic spectrum
Question 2 (iv): Describe in detail the electromagnetic spectrum with the help of a diagram. (6)
Meaning. The electromagnetic spectrum is the full, continuous range of electromagnetic radiation (EMR), arranged by wavelength or frequency, from very short gamma rays to very long radio waves. All EMR moves at the speed of light, about 3 × 108 m/s, and follows c = νλ. So a shorter wavelength means a higher frequency and, since energy Q = hν, more energy per photon.
Diagram to draw. A long horizontal bar divided into seven bands, left to right: gamma rays, X-rays, ultraviolet, visible, infrared, microwave, radio. Mark the boundaries 10 nm (UV start), 0.4 µm and 0.7 µm (visible), 1 mm (microwave start) and 1 m (radio start). Label the left end shorter wavelength, higher frequency and energy and the right end longer wavelength, lower energy. Below the bar, enlarge the visible band into blue (0.4 to 0.5 µm), green (0.5 to 0.6 µm) and red (0.6 to 0.7 µm) with two guide lines running up to the main bar. The full file carries this as a labelled figure.
- Gamma rays and X-rays (below about 10 nm): the atmosphere absorbs these almost completely, so they are not used to image the earth's surface.
- Ultraviolet (about 10 nm to 0.4 µm): ozone absorbs much of it and the rest scatters strongly, which limits its use in remote sensing.
- Visible (0.4 to 0.7 µm): the only band our eyes see, split into blue, green and red. Aerial photographs and true colour images work here.
- Infrared (0.7 µm to about 1 mm): near infrared (0.7 to 1.3 µm) is reflected strongly by healthy leaves, which is why vegetation looks red on a false colour composite. Thermal infrared, especially the 8 to 14 µm window, records heat given off by surfaces, even at night.
- Microwave (about 1 mm to 1 m): passes through cloud and haze, so active radar sensors, such as those on India's RISAT satellites, can image day and night in any season. Radio waves, longer than 1 m, serve communication rather than imaging.
Atmospheric windows. Only some wavelengths pass the atmosphere without heavy absorption by water vapour, carbon dioxide and ozone. These windows decide which bands a sensor records.
Conclusion. Water, soil and vegetation respond differently in each band, giving each surface a spectral signature, the basis of reading satellite images.
Map scale and the three ways of showing it
Question 3: What is a map scale? Describe the three ways of representing map scale. (10)
Meaning of map scale. A map scale is the ratio between a distance measured on a map and the matching distance on the ground. Every map is far smaller than the area it shows, so the scale tells the reader how much the ground has been reduced. Put simply, scale = map distance ÷ ground distance. Without it, nobody could measure distance, area or direction on the map with any confidence.
Scale also decides detail. A map at 1:10,000 is a large scale map that shows a small area in detail, while 1:1,000,000 is a small scale map covering a large area with little detail. The smaller the denominator, the larger the scale.
1. Statement or verbal scale
The scale is written in words, for example "1 cm represents 5 km" or "1 inch to 1 mile". Its merit is that anyone can understand it at a glance. Its weakness is that it depends on one system of units, so a reader used to kilometres may struggle with miles. It also becomes wrong the moment the map is enlarged or reduced.
2. Representative fraction (RF)
The scale is a fraction or ratio whose numerator is always 1, with both parts in the same unit. An RF of 1:50,000 means one unit on the map stands for 50,000 of the same units on the ground, whether centimetres or inches. Because it carries no unit, it is read the same way everywhere, which is why it is often called the international scale.
Converting a statement into RF: "1 cm represents 10 km". Since 1 km = 100,000 cm, 10 km = 1,000,000 cm, so the RF is 1:1,000,000.
Converting RF into a statement: 1:50,000 means 1 cm = 50,000 cm = 0.5 km, so "1 cm represents half a kilometre". In the British system, "1 inch to 1 mile" becomes 1:63,360, because a mile has 63,360 inches.
The limitation of RF is that a lay reader must do this arithmetic, and it too fails if the map is photocopied at a different size.
3. Graphical, linear or plain scale
A straight line is divided into primary and secondary parts and labelled in ground distance, so distances can be read straight off with a pair of dividers.
Worked construction. Take an RF of 1:50,000, where 1 cm = 0.5 km. A line of 10 cm will therefore show 5 km. Divide it into five primary parts of 2 cm, each worth 1 km. Place zero at the end of the first primary part and split that left-hand part into five secondary divisions of 0.4 cm, each worth 200 m.
Diagram to draw. A horizontal bar 10 cm long, outlined and divided into five equal primary parts, with alternate parts shaded so they stand out. Put the zero mark at the end of the first primary part, number the parts to its right 1, 2, 3 and 4 km, and divide the part to its left into five secondary divisions numbered back towards 1 km in steps of 200 m. Write the RF and "1 cm = 0.5 km" below the bar. The full file carries this as a labelled figure.
The great strength of the graphical scale is that it grows or shrinks along with the map, so it stays correct after enlargement, reduction or digital zooming. Diagonal and vernier scales are refinements of the same idea that allow even finer readings.
| Method | Example | Main strength | Main weakness |
|---|---|---|---|
| Statement | 1 cm represents 5 km | Easy for a general reader | Tied to one unit system; wrong after resizing |
| Representative fraction | 1:50,000 | Unitless, so read the same in any country | Needs conversion; wrong after resizing |
| Graphical | Bar of 10 cm marked 0 to 4 km plus 1 km of 200 m divisions | Stays true when the map is enlarged or reduced | Must be constructed carefully; slower to draw |
Conclusion. Each method suits a different reader, which is why most maps, including Survey of India topographical sheets, print the RF together with a graphical scale. A cartographer who can move confidently between all three forms can use any map, at any size, without error.

4. Blocks, Units and Topics
BGGCT 133 General Cartography is built on five blocks: Introduction to Cartography, Map Projections, Sources of Data, Map Reading and Interpretation, and Representation of Data.
The table links each block to the topics it teaches and to the June 2026 questions drawn from it. Unit numbers appear only where we confirmed them on eGyanKosh; the rest are described by topic.
| Block | Block title | Confirmed unit | Key topics | June 2026 questions |
|---|---|---|---|---|
| Block 1 | Introduction to Cartography | Unit 3: Map Scale | Nature, scope and history of cartography; basic elements of a map; statement, RF and graphical scales | Q1(i), Q1(iii), Q2(i), Q2(vi), Q3 (Sample 2) |
| Block 2 | Map Projections | Unit 5: Cylindrical Projections; Unit 7: Zenithal Projections | Graticule and its properties; Mercator and simple cylindrical grids; polar zenithal stereographic and gnomonic cases | Q1(v), Q1(vii), Q2(ii), Q2(iii), Q3 (Or) |
| Block 3 | Sources of Data | Unit 8: Sources | Primary data tools such as schedules and focus groups; Census of India series and the All India Educational Survey; scanners and the electromagnetic spectrum | Q1(ii), Q2(iv) (Sample 1), Q2(v), Q4, Q4 (Or) |
| Block 4 | Map Reading and Interpretation | Unit 11: Topographical Maps | Survey of India sheets and open series numbering; contours for hills, cliffs and slopes; weather maps and Indian seasons | Q5, Q6, Q7, Q7 (Or) |
| Block 5 | Representation of Data | — | Bar, line and pie diagrams; climograph, ergograph and hythergraph; choropleth, isopleth, choroschematic and isochrone maps | Q1(iv), Q1(vi), Q2(vii), Q5 (Or), Q6 (Or) |
Every unit is open to read on IGNOU's eGyanKosh page for BGGCT-133, and our answers are written from that text. If you want block-wise revision notes rather than exam answers, our BGGCT 133 Study Material covers the same five blocks in shorter, easier pages.
Blocks 1, 2, 3 and 5 each fed five questions this time, while Block 4 gave four, all of them long Section C questions. That makes topographical maps, weather and contours the block where a weak answer costs the most marks.
5. Question Paper Pattern and Marks Split
The paper carries 100 marks in 3 hours, split into Section A (5 × 4), Section B (5 × 6) and Section C (5 × 10), with 24 questions printed and 15 to be answered.
| Section | Questions printed | To answer | Word limit | Marks |
|---|---|---|---|---|
| A (Q1) | 7 short questions, (i) to (vii) | Any 5 | 150 words each | 5 × 4 = 20 |
| B (Q2) | 7 medium questions, (i) to (vii) | Any 5 | 250 words each | 5 × 6 = 30 |
| C (Q3 to Q7) | 5 questions, each with an "or" choice (10 printed) | All 5, one choice each | 500 words each | 5 × 10 = 50 |
| Total | 24 | 15 | About 4,500 words | 100 |
Section C decides the result. Half the marks sit in five long answers, and four of the ten choices asked for a neat sketch or diagram. If you are comparing papers across programmes, our BSCG Question Paper page puts the sister courses side by side.
One small change from older papers is worth noticing. The June 2026 note says "attempt all Sections" instead of "attempt all questions", but the inner choice is unchanged: any five in A and B, and one option from each Section C pair.
6. Cartography Topics That Keep Returning
Four topics, map scale, topographical maps, one-dimensional diagrams and relief by contours, appeared in all seven official BGGCT-133 papers we found from December 2021 to December 2025.
We read the official IGNOU papers for December 2021, June 2022, December 2023, June 2024, December 2024, June 2025 and December 2025. The December 2022 and June 2023 papers were not available on IGNOU's websites when we checked, so they are not counted. Each count shows in how many of the seven papers a topic was asked at least once.

| Isopleth, isochrone, choroschematic and dot methods | Q6 (Or) | 4 | Jun 2022, Dec 2023, Jun 2024, Jun 2025 |
| Scanner-based remote sensing data (pushbroom so far) | Q4 (Or) | 3 | Dec 2021, Jun 2024, Jun 2025 |
| Seasonal character of Indian weather | Q6 | 2 | Jun 2022, Dec 2023 |
| Electromagnetic spectrum | Q2(iv) (Sample 1) | 2 | Dec 2024, Dec 2025 |
| Pie or circular diagram | Q1(vi) | 1 | Dec 2024 |
| All India Educational Survey | Q1(ii) | 1 | Dec 2021 |
| Map drawing equipment | Q1(iii) | 1 | Dec 2023 |
The seven topics at the top of the table make up almost half of what a student needs, and they are the first to master before the December 2026 exam. See our IGNOU Solved Guess Paper page for the same treatment across other courses.
Watch the remote sensing row. Earlier papers asked about pushbroom scanning three times, but June 2026 asked about opto-mechanical, or whiskbroom, scanners instead. Students who had learnt only pushbroom were caught out, and the full file explains how the two systems differ.
7. How Our Answers Are Written and Checked
Each BGGCT 133 answer is written from the IGNOU block text, matched to the marks and word limit printed beside it, and checked before it goes into the file.
Our geography writer first places every question in its block and unit, then drafts the answer from the eGyanKosh material so terms like representative fraction, graticule and isopleth are used exactly as IGNOU uses them. Facts such as wavelengths, RF conversions and census series are checked line by line.
Sketches are redrawn cleanly and labelled: a graphical scale with its primary and secondary divisions, a Mercator grid with widening parallels, contours spaced for a conical hill and crowded for a cliff.
We also compared each question with the older sessions in our IGNOU Previous Year Question Paper collection. Where a topic was asked before in a different form, the answer is written so it still works if the wording changes in December 2026.
8. Solved File Index for All 24 Questions
The June 2026 solved file answers all 24 printed questions; 2 are open on this page and 22 are in the full file only.
BGGCT-133 is a theory course, so instead of a lab record this index lists every question with its marks, block and where you can read the answer. The practical exercises belong to the separate BGGCL-134 laboratory course.

9. Programmes That Study BGGCT 133
BGGCT 133 General Cartography is sat by students of the Bachelor of Science (General), BSCG, and IGNOU also lists it for the Bachelor of Science (Multidisciplinary), BSCM.
The June 2026 paper is printed under the IGNOU Bachelor of Science (General) heading, where it sits among the geography discipline courses with Physical Geography, Human Geography and Environmental Geography. IGNOU's 2026 assignment booklet for BGGCT-133 names both BSCG and BSCM learners.
Learners in other programmes who take Geography should check their programme guide to confirm the course code before ordering. Whichever programme you are in, the paper and the solved file are the same.

11. BGGCT 133 General Cartography FAQs
Quick answers to the questions BSCG students ask most about the BGGCT 133 June 2026 solved paper.
How do I get the full solved question paper on WhatsApp?
Send a WhatsApp message to 9899436384 with the code BGGCT 133 and the session June 2026. Our team confirms the order in the chat and shares the solved file as a PDF on the same number. The file answers all 24 questions printed in the paper, including both choices of every Section C question. Two of those answers are open on this page; the other 22 are only in the file.
Which June 2026 questions are fully solved on this page?
Two answers are shown in full. The first is Q2(iv) from Section B, which asks you to describe the electromagnetic spectrum with a diagram and carries 6 marks. The second is Q3 from Section C, which asks what a map scale is and how it can be shown in three ways, worth 10 marks. Together they show how a short and a long General Cartography answer should look.
How many questions were printed in the June 2026 paper?
The paper printed 24 questions across three sections. Section A had seven short questions and Section B had seven medium questions, and you answer any five from each. Section C had five compulsory questions, each with an "or" choice, so ten were printed and you answer five. A student therefore writes 15 answers in three hours for a total of 100 marks.
Is BGGCT 133 a theory paper or a lab course?
BGGCT 133 is the theory course, examined through a three-hour, 100-mark term-end paper. The hands-on exercises sit in a separate laboratory course, BGGCL-134 General Cartography: Laboratory. Even so, the theory paper keeps asking for drawings, such as Mercator's projection with a neat sketch or contours for a conical hill and a cliff, so practising diagrams matters for this exam too.
Which BGGCT 133 topics repeat most often in IGNOU exams?
Across the seven official papers we found, from December 2021 to December 2025, four topics appeared every time: map scale, topographical maps, one-dimensional diagrams and relief shown by contours. Census of India data series, sources of data and thematic maps followed in six papers each. The June 2026 paper asked all seven of these topics again, which shows how steady the pattern is.
Are the answers written to IGNOU word limits?
Yes. Every answer follows the limit printed in the paper: about 150 words for the 4-mark Section A questions, about 250 words for the 6-mark Section B questions and about 500 words for the 10-mark Section C questions. Each one starts with a clear definition, moves through the points the question asks for and ends with a short conclusion, which is the shape IGNOU evaluators look for.
Will the June 2026 solved paper help in the December 2026 exam?
It should help a great deal, though no file can promise which questions will come. BGGCT-133 papers reuse a steady set of topics, so practising the June 2026 answers covers map scale, projections, census data, contours and diagrams that keep returning. Pair it with your block-wise reading and at least one more past paper, and you will walk in having already written most likely answers once.
Which programmes take the BGGCT 133 exam?
The June 2026 paper itself is printed for the Bachelor of Science (General), BSCG, and IGNOU's 2026 assignment booklet for BGGCT-133 lists both BSCG and the Bachelor of Science (Multidisciplinary), BSCM. If you are enrolled in another programme and see BGGCT-133 on your hall ticket, the same paper and the same solved file apply to you.
