The Government of India, in consultation with the Arunachal Pradesh government, has standardized the names of 27 places and geographical features in the state on official Survey of India maps. The list covers land areas, four mountain passes, Sambho Sarovar lake, and the Sher-e-Thapa Memorial. The decision gives uniform official recognition to locations that carry geographical, strategic, and historical importance along India’s eastern frontier.
What the Government Standardized
The Ministry of Home Affairs announced the decision on 7 August 2026. The Union government completed the exercise in consultation with the Government of Arunachal Pradesh, and the standardized names were recorded on the official maps of the Survey of India (SoI).
The stated purpose is to support accurate identification of the locations and improve public awareness of them. The exercise covers different types of geographical and historical features rather than only inhabited settlements. This distinction is important because an official map can record a pass, lake, or memorial alongside a land area when each has a clear place in the state’s geographical record.
The 27 Features on the Survey of India Map
The official list contains 21 land areas, four mountain passes, one lake, and one monument. The names and categories are as follows:
| Category | Names | Count |
|---|---|---|
| Land areas | Longju, Maja, Bisa, Bara Kundun, Chhota Kundun, Dhan Bari, Pritnagar, Buddhamandir, Jairampur, Teritnagar, Ramnagar, Jaswant Garh, Sagar, Padma, Jyotinagar, Baisakhi, Chhota Ropuk, Bara Ropuk, Shivaji Nagar, Sunpura, Kamlang Nagar | 21 |
| Mountain passes | Dzo La, Riza La, Pukur La, Thag La | 4 |
| Lake | Sambho Sarovar | 1 |
| Monument | Sher-e-Thapa Memorial | 1 |
The updated Arunachal Pradesh state map is available through the Survey of India’s state maps portal. The list therefore creates a common reference for official cartography and for public use of these names.
Why Survey of India Maps Matter
The Survey of India is the National Mapping Agency of India under the Department of Science and Technology. Established in 1767, it is the oldest scientific department of the Government of India. Its work includes national surveying, map preparation, geodetic activity, and the production of base maps used for development, administration, and national security.
Official standardization is different from an informal or locally used name. When a feature is included in a government map, it becomes part of a consistent reference system used by public authorities and map users. In a border state, consistent geographical records also help reduce ambiguity about the location and identity of features that may have administrative, security, or historical relevance.
The decision is also consistent with the wider importance of geospatial information in governance. India’s National Geospatial Policy 2022 seeks to strengthen the use of geospatial data and services for national development, security, and public access, while protecting sensitive information where necessary.
Strategic and Historical Significance
Arunachal Pradesh lies in India’s northeast and shares international boundaries with Bhutan, China, and Myanmar. Its northern boundary with Tibet is part of the wider India-China boundary dispute. The McMahon Line, drawn during the 1914 Simla Convention, is accepted by India as the boundary in the eastern sector, while China rejects it and claims Arunachal Pradesh as part of what it calls southern Tibet.
Several names in the new list are connected with the history of the frontier. Longju is associated with an India-China confrontation in 1959, while Thag La is a high-altitude pass linked to the opening phase of the 1962 India-China war. Jaswant Garh commemorates Indian Army Rifleman Jaswant Singh Rawat, who fought during the 1962 conflict.
The Sher-e-Thapa Memorial honours Havildar Shere Thapa, who served in the 2nd Battalion, Jammu and Kashmir Rifles, during the 1962 war. The inclusion of these places alongside passes and natural features connects cartographic recognition with the military history and lived geography of the region.
The Arunachal Pradesh Naming Dispute
China has periodically announced its own names for places in Arunachal Pradesh. The first major list in this series appeared in 2017, followed by further lists in 2021, 2023, and 2024. Beijing presents the exercise as part of its claim over the state, but India has consistently rejected the claim and stated that changing a place name cannot change the territorial reality.
The latest Indian measure should therefore be understood as an official cartographic and administrative standardization, not as a new boundary agreement. It records India’s established names through its national mapping agency and improves consistency in government maps. It does not by itself settle the India-China boundary dispute or replace negotiations and established border-management mechanisms.
What the Decision Means
The move has three immediate effects. First, it creates a uniform set of names for use in official Indian maps. Second, it draws attention to geographical features that are important for understanding the eastern frontier, including high-altitude passes, settlements, a lake, and sites linked to the 1962 war. Third, it places the record within an institutional framework involving the Ministry of Home Affairs, the Arunachal Pradesh government, and the Survey of India.
The decision also shows why place names can have significance beyond language. Maps influence how territory is identified in administration, public information, infrastructure planning, and historical memory. At the same time, the practical value of the exercise will depend on consistent use of the standardized names across government records, mapping products, and public communication.
Key Takeaways
- The Government of India, in consultation with Arunachal Pradesh, standardized 27 places and geographical features on official Survey of India maps.
- The list contains 21 land areas, four mountain passes, one lake, and one monument.
- The four mountain passes are Dzo La, Riza La, Pukur La, and Thag La.
- Sambho Sarovar is the lake and Sher-e-Thapa Memorial is the monument included in the list.
- The Survey of India, established in 1767, is India’s National Mapping Agency under the Department of Science and Technology.
- The map standardization records India’s official names but does not settle the India-China boundary dispute.
