In the context of a panel I put together on “Turning Ploughshares into Swords: Weapons and Weaponizations”, the ISA’s annual conference was the occasion for me to present some of the research I have undertaken as part of my long term project into the logistics of military perception. The central aim of that project is to uncover the genealogy and operation of the functional constituents of contemporary targeting practices as they increasingly span the globe. I submit that we can outline three distinct, if profoundly intertwined, functions of sensing, imaging and mapping that respectively gather sensorial information, visually represent and disseminate it, and relate it to geospatial frameworks. It is the last of these operations that was the focus of my paper, with particular attention paid to the way in which the planet has increasingly been enframed within systems of geographic coordinates permitting the geolocation and thereby targeting of any entity caught within their mesh.
While the role of cartography in European colonial expansion from the fifteenth century on is well-known, my main interest here lies in the even more intimate relationship between the histories of weapons targeting and techniques of geospatialisation. From the outset, the development of artillery in the early modern era was closely bound up with that of surveying techniques for the measurement of distances by visual means. Indeed, the range-finding exercises of gunners relied on the same trigonometric methods that underpinned the rise of modern cartography.
