Mapping an empire

Description

From James Rennell's survey of Bengal (1765-71) to George Everest's retirement in 1843 as surveyor general of India, geography served in the front lines of the British East India Company's territorial and intellectual conquest of South Asia. In this history of the British surveys of India, focusing especially on the Great Trigonometrical Survey (GTS) undertaken by the Company, Matthew H. Edney relates how imperial Britain employed modern scientific survey techniques not only to create and define the spatial image of its Indian empire but also to legitimate its colonialist activities as triumphs of liberal, rational science bringing "civilization" to irrational, mystical, and despotic Indians. The reshaping of cartographic technologies in Europe into their modern form, including the adoption of the technique of triangulation (known at the time as "trigonometrical survey") at the beginning of the nineteenth century, played a key role in the use of the GTS as an instrument of British cartographic control over India. In analyzing this reconfiguration, Edney undertakes the first detailed, critical analysis of the foundations of modern cartography. The success of these new techniques in mapping British India depended on the character of the East India Company as a gatherer and controller of information, on its patronage system, and on the working conditions of surveyors in the field. Drawing on a wealth of data from the Company's vast archives, Edney shows how these institutional constraints undermined the GTS and destabilized this high point of Victorian science to the point of reducing it to "cartographic anarchy." Thus, although the GTS served at the time to legitimate British rule in India, its failure can now be seen as a metaphor for British India itself: an outward veneer of imperial potency covering an uncertain and ultimately weak core.
