- Remember the Important Latitudes and Longitudes of India.
- Mainland India extends between latitudes 8°4′ N and 37°6′ N and Longitudes 68°7′ E and 97°25′ E. The southernmost point of India (6°45′ N) lies on the Great Nicobar Island and is called the Indira Point.
- The Standard Meridian of India is 82°30′ E. The Indian Standard Time (IST) is ahead of the Greenwich Mean Time (GMT) by 5 hours and 30 minutes.
- In India, the Standard Meridian passes through 5 states – Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha, and Andhra Pradesh.
- The Tropic of Cancer (23°30′ N) passes through 8 Indian states – Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram.
- The Tropic of Cancer and the Standard Meridian of India intersect in the Korea (Koriya) district in Chhattisgarh.
2. States and Union Territories of India
POINTS TO REMEMBER:
- You must remember the capital cities of each State and Union Territory (UT). You should also have a general idea of the location of these cities. Questions can be asked about their locations with respect to the Tropic of Cancer, Standard Meridian, or other important geographical features.
- The Union Territory of Jammu & Kashmir has two capital cities – Jammu during winter and Srinagar during Summer.
- Area-wise, Rajasthan is the largest state in India, followed by Madhya Pradesh and Maharashtra. Goa is the smallest state followed by Sikkim and Tripura.
- Similarly, Ladakh is the Largest Union Territory of India and Lakshadweep is the smallest.
- The UT of Puducherry is scattered over three Indian states. Its capital (Puducherry) and Karaikal are the enclaves of Tamil Nadu. Yanam and Mahé are enclaves of Andhra Pradesh and Kerala, respectively (Check on the Map).
- You should know the general locations of each State and UT and with which countries or other Indian states/UTs they share their border. For example, Uttar Pradesh shares its border with 1 Country (Nepal), 8 Indian States (Can you name them all? Check the map above), and the Union Territory of Delhi.
- Pay special attention to the Northeastern states and their Capitals.
- The North Eastern Region (NER) comprises of Eight states – 1. Arunachal Pradesh, 2. Assam, 3. Manipur, 4. Meghalaya, 5. Mizoram, 6. Nagaland, 7. Tripura (These 7 states are commonly known as the “Seven Sisters“) and 8. Sikkim (Often referred to as the “Brother” of the Seven Sisters)

- You must remember all the Indian States/UTs that share borders with other countries along with some important facts. For example, West Bengal is the state that shares the longest international border, while Nagaland has the shortest international border.
- Please note that when I say you must “remember” these Indian states, I DO NOT mean that you should just note down these states’ names and memorize them blindly. That would be a very wrong way to approach your maps preparation and in the long term, it is not going to be very helpful. Instead, you should know the locations of these states and whenever such questions are asked, you should visualize the map in your mind and then approach the questions accordingly. Please refer to my article on how to study maps for UPSC to learn more about studying maps effectively.

- For more important facts, please refer to the article ‘Major Lakes of the World‘.
10. Major Straits & Channels of the World
POINTS TO REMEMBER:
- A strait is a narrow passage of water that connects two seas or two other large bodies of water. It separates two large land masses through which it passes. A channel, on the other hand, is a relatively wider strip of water connecting two large water bodies. (Check on the map above: Strait of Hormuz and Mozambique Channel)
- Apart from knowing the locations of these straits & channels, you should also know which two water bodies they connect and which two landmasses they separate. For example, The Strait of Hormuz connects the Gulf of Oman and the Persian Gulf, while it separates Iran from Oman.
- Straits are often in the news: sometimes due to their presence in a particular shipping route, sometimes due to some military exercises held in and around these straits, and sometimes due to other strategically important reasons. Follow them thoroughly.
11. Mediterranean Region
POINTS TO REMEMBER:
- The Mediterranean Sea is bordered by 22 countries (including Palestine) and one territory (Gibraltar – a British Overseas Territory) spanning across Europe, Africa, and Asia.
- ‘Number’ of countries may not be asked as there is some ambiguity due to territorial disputes in certain areas. But questions have been and can be asked about the countries bordering the Mediterranean Sea.
Please refer to the article on Mediterranean Sea Bordering Countries to know the important facts about this region.
12. The Middle East and the Persian Gulf Region
POINTS TO REMEMBER:
- The Middle East is not officially defined as a distinct grouping, and various organizations may include different countries or territories in their definitions, or may not categorize it as a region at all. However, the countries/territories shown in green on the map above represent a consensus approximation of what is generally accepted as the Middle East region.
- For several decades now, the Middle East has consistently been at the forefront of key geopolitical issues. From an examination perspective, this region holds significant importance, not only for Prelims but also for the Mains exam. You should thoroughly follow the current affairs related to this region.
- You should also know the countries that border the major water bodies in and near the Middle East. For example, the Gulf of Aqaba is bordered by four countries – Egypt, Saudi Arabia, Jordan, and Israel, while the Gulf of Suez is bordered by only one country – Egypt.
13. Israel & Neighbouring Areas
POINTS TO REMEMBER:
- This is one of the most important regions in the Middle East and a major conflict zone in the world.
- You should have a good understanding of the Israel-Palestine conflict.
- The status of Jerusalem has been described as “one of the most intractable issues in the Israeli–Palestinian conflict” due to the long-running territorial dispute between Israel and the Palestinians, both of which claim it as their capital city.
- Most countries and organizations support that West Jerusalem and East Jerusalem should be allocated as capital cities to the Israelis and the Palestinians, respectively; this position has been endorsed by the United Nations, the European Union, and France, among others. Russia already recognizes East Jerusalem as the Palestinian capital and West Jerusalem as the Israeli capital.
- With respect to the Israel-Palestine conflict, India believes in a Two-State Solution and proposes the right to self-determination to both countries in a peaceful manner. However, the Indian government does not currently recognize Jerusalem as Israel’s capital. India is represented in Israel through an embassy in Tel Aviv.

These were some of the important maps for UPSC preparation. As I mentioned at the beginning of the article, these maps are meant to ‘assist’ you in your preparation. However, it is crucial to study various other map-related topics as well. Other important maps to cover include Tiger Reserves, National Parks, Ramsar sites, Soils in India, Ocean Currents, etc.
Feel free to add value wherever needed to these 28 maps that I have provided above, but avoid overdoing it. Remember, there are other subjects to cover, and effective revision is essential. Allocate your time wisely.
