Case Study 3.2: Mapping the Colony — Cartography as Surveillance in British India
Overview
This case study examines the Survey of India — specifically the Great Trigonometrical Survey (GTS) conducted by the British colonial administration between 1802 and 1871 — as a case study in how cartographic surveillance served colonial power. It also examines how indigenous spatial knowledge was extracted, transformed, and made legible to colonial authority through the mapping process.

Background: The Survey of India
The Survey of India was established in 1767, shortly after the East India Company consolidated control over Bengal following the Battle of Plassey (1757). Its founding purpose was explicitly military: British forces needed accurate maps to plan campaigns, move troops, and secure supply lines in an unfamiliar subcontinent.
Over the following century, the Survey's ambitions expanded dramatically. The Great Trigonometrical Survey, initiated by Colonel William Lambton in 1802 and continued by George Everest (after whom the mountain is named) and his successors, aimed at nothing less than the comprehensive geodetic mapping of the entire Indian subcontinent — measuring the precise dimensions of the Earth's curvature, establishing a network of precisely located points that could serve as the foundation for all subsequent regional mapping.
The GTS was both a scientific achievement of the first order and an instrument of imperial power. These two aspects were inseparable.
How Cartographic Surveillance Worked
Making the Land Legible
Before the British surveys, India had existing mapping traditions — the Mughal administrative maps, regional cartographic knowledge maintained by local administrators and traders, and the embodied geographical knowledge of guides, merchants, and travelers who had traversed the land for generations.
British colonial cartography did not simply add to this existing knowledge. It replaced the existing representational system with a different one — one organized around British administrative categories, British place-name conventions, and a British geometric framework that made the territory readable to officials in Calcutta and London.
This transformation served specific surveillance functions:
Taxation: Accurate land surveys enabled the British to assess land revenue — the primary source of colonial income in India. The Permanent Settlement (1793) in Bengal fixed land revenue obligations based on land assessments. Accurate maps were necessary to determine what was assessable.
Military planning: Detailed topographic maps enabled British forces to plan campaigns against Indian states and princes who resisted Company authority. The absence of accurate maps had hampered early British military operations; systematic cartography was a military investment.
Resource identification: Maps identified forests, rivers, mines, and agricultural zones — information that enabled systematic extraction of resources for metropolitan benefit.
Administrative boundary-drawing: The Survey established the boundaries of administrative units (provinces, districts, sub-districts) that became the organizational framework of colonial governance. These boundaries often cut across pre-existing political, cultural, and ecological boundaries, reorganizing space according to administrative convenience rather than social reality.
The Pundits: Indigenous Knowledge as Surveillance Tool
One of the Survey of India's most striking chapters involved the employment of trained indigenous agents — known as "pundits" or "native explorers" — to map territories that British officers could not safely enter. Tibet, Central Asia, and the Himalayan borderlands were inaccessible to British survey parties; the pundits went where the British could not.
Trained in surveying techniques, the pundits traveled in disguise as pilgrims or merchants, counting their steps with modified prayer beads (each bead representing 100 steps), measuring altitude with hidden thermometers in their equipment, recording routes, landmarks, and settlements in code. Their data was then incorporated into British maps.
The pundits represent a complex form of colonial surveillance: indigenous knowledge holders transformed into intelligence agents for colonial authority, their embodied geographical knowledge extracted and converted into the cartographic system of the colonizing power. The pundits were skilled, brave, and often remarkable — and their contribution was systematically minimized in official British accounts, which credited the surveys to their British supervisors.
The Production of Colonial Space
Geographer Matthew Edney's Mapping an Empire (1997) argues that the Survey of India did not simply map a pre-existing India — it helped produce the idea of India as a unified, bounded, knowable space.
Before the Survey, "India" was a geographic concept without precise content — a term applied to a vast and diverse region of different polities, languages, cultures, and ecologies. The Survey's systematic grid of triangulation points, covering the entire subcontinent with a unified coordinate system, created a representational India that could be administered from a distance.
This "production of space" through surveillance is a general feature of state power, not just colonial power. James Scott's Seeing Like a State argues that all modern states engage in this kind of "legibility work" — standardizing and simplifying complex social and geographic realities to make them governable. The colonial version was distinctive in the degree of coercive imposition and in the erasure of indigenous representational systems.
Place-Name Transformation
The Survey systematically anglicized or simplified place names, often rendering local names in phonetically inconsistent ways or replacing them entirely with English names. Mountains, rivers, towns, and regions that had been known by one or multiple names in local languages were given canonical English-language names that appeared on British maps and became the official administrative designations.
Mount Everest — named by the Survey after George Everest — was known locally as Chomolungma (Tibetan) and Sagarmatha (Nepali). The British name, applied by the colonial cartographic authority, became the global standard. The renaming is not trivial: to name a place is to claim authority over it, to insert it into your representational system rather than acknowledging existing systems.
Applying Chapter 3 Concepts
Cartography as Dataveillance
The Survey of India was dataveillance in its most literal sense: the collection and processing of data traces (measurements, observations, triangulations) to produce a model (the map) of a territory and its population.
The map as data product was then used for purposes of influence, management, protection, and direction — exactly Lyon's definition of surveillance. The map enabled: - Tax assessment (management) - Military planning (protection of colonial interests) - Administrative organization (direction of colonial governance) - Political influence over border states
Visibility Asymmetry at the Imperial Scale
The Survey created visibility asymmetry at the imperial scale. After the GTS, British colonial administrators in Calcutta and London could see the Indian subcontinent — its terrain, resources, borders, administrative divisions — in a way that no Indian administrator had ever been able to see it before.
This imperial visibility was not available to the population being mapped. The maps were British products, kept in British archives, used by British administrators. The peasant whose land was being assessed by a revenue survey could not access the map that had been made of their village.
Colonial Legibility and Social Sorting
The Survey's creation of legible space enabled social sorting at the geographic scale. Once the territory was mapped, colonial administrators could classify areas as: - Settled and revenue-producing (administered directly) - Forest zones (subject to Forest Acts that restricted indigenous forest use) - Tribal territories (subject to special laws) - Frontier zones (subject to military administration)
These classifications attached different legal regimes to different spaces and, by extension, to the people who inhabited them. The inhabitants of forest zones lost traditional land use rights. The inhabitants of tribal territories were placed under different governance structures. The map's categories became the basis for differential treatment of populations — social sorting at the geographic scale.
The Legacy
The maps produced by the Survey of India outlasted the British Empire. Independent India and Pakistan (and subsequently Bangladesh) inherited the Survey's administrative boundaries, its place-name conventions, and its cartographic framework. The colonial legibility infrastructure became the administrative infrastructure of postcolonial states.
The India-Pakistan border — the Radcliffe Line — was drawn in 1947 by a British lawyer, Cyril Radcliffe, who had never been to India before arriving six weeks before independence to draw the line. He used the Survey's maps to divide the subcontinent between the two successor states. The hastily drawn border created one of the largest forced population movements in history — approximately 10–20 million people displaced, with hundreds of thousands killed in communal violence. The cartographic surveillance infrastructure of the colonial era directly produced the border whose consequences continue to shape South Asian geopolitics.
Discussion Questions
-
Cartography and Power: The chapter argues that maps are surveillance technologies. Is this argument convincing? In what ways is a map a surveillance document, and in what ways is it something else — a navigational tool, a scientific record, an artistic work?
-
The Pundits' Dilemma: The pundits who served the Survey of India were coerced or co-opted into serving colonial surveillance goals. Their indigenous knowledge was extracted and incorporated into a system that served to govern and control their own communities. How should we evaluate their participation? Is there a meaningful difference between the pundits and the Stasi IMs discussed in Case Study 3.1?
-
Legibility and Governance: James Scott argues that "legibility" — making populations and territories manageable from a distance — is a general feature of state power, not just colonial power. Is there a version of legibility-work that is legitimate? Can states govern justly without making their territories and populations legible? What would a legitimate version of population legibility look like?
-
The Naming Power: The Survey's systematic anglicization of place names is presented as a dimension of colonial surveillance. Does the act of naming a place constitute a surveillance act? What is the relationship between naming and power in non-colonial contexts?
-
Cartographic Inheritance: Postcolonial states inherited the Survey's maps and borders. Does the colonial origin of these borders obligate current governments to redraw them? Or does the passage of time and the establishment of new political facts make the colonial origin irrelevant? How does this question apply to surveillance data: if contemporary algorithms are trained on historically biased data, are they perpetually compromised by that origin?
-
Digital Cartography: Google Maps, Apple Maps, and satellite imaging services now map the entire Earth with precision far exceeding the Survey of India. Who controls these maps, and for what purposes? Does the commercialization of global cartography represent a continuation of the Survey's surveillance logic, or something qualitatively different?
-
Jordan's Connection: Jordan's phone uses a mapping application that knows their location at all times. That application is built on a global mapping infrastructure. How does understanding the history of cartography as surveillance change how you might think about everyday navigation technology?
Extension Research
Research the mapping of one contemporary urban area by a major tech company's street-view mapping program (Google Street View, or an equivalent). Consider:
- What data is collected beyond the street-level imagery (Wi-Fi network identifiers, business data, structural data)?
- Who has access to the resulting data?
- How is the data used beyond navigation (advertising targeting, insurance assessment, real estate valuation, law enforcement)?
- Are there communities where street-view mapping has been refused or has generated significant resistance? What were the concerns?
Write a 400-word analysis connecting contemporary commercial cartography to the colonial cartography discussed in this case study. What is continuous? What is different?
