The paper explores the connection between computerised techniques of mapping and the role of maps in modern nationhood, interrogating the ways that maps are naturalised and deployed in postcolonial neoliberal statecraft. A case study of Ecuador demonstrates how the relationship between cartography and the nation-state is being both altered and reaffirmed by new mapping practices and institutional processes. Despite neoliberalising moves to decentre state cartographers and the technological advances supporting the proliferation of national maps and map-makers, Ecuadorian cartographies are still authorised by the nation-state, as explored in relation to spatial information about the country, and in relation to the processes of land-titling. Under neoliberal governance and with advanced mapping techniques, land-titling produces small territories that replicate – in miniature – the jigsaw-like and modular quality of national territories. As such, mappings of individual private properties produce the reality of neoliberal statecraft. [ABSTRACT FROM AUTHOR]

Cotopaxi is an active volcano in Ecuador, whose eruptions are characterized by producing destructive primary lahars which represent a major risk for the country. The hazard assessment related to such lahars relies largely on the knowledge of the latest event, which occurred on 26 June 1877, for either scenario definition or simulation calibration. A detailed (1:5000 scale) cartography of the deposits belonging to that eruption has been obtained in the proximal northern drainage of Cotopaxi. The cartography was performed through a combination of geological fieldwork, as well as the analysis and interpretation of high-definition imagery obtained by drone surveys combined with the Structure from Motion technology for image processing. Such imagery included red and green visible bands, and a near-infrared band, which allowed the obtention of NDVI imagery where the primary lahar deposits were identified and cartographed with support of fieldwork data. Both data sources are mutually complementary, and the final cartography would be impossible if any of them were not available. The results obtained represent a significant advance for the level of detail with respect to previous cartographic works. Moreover, they should allow an improved calibration of the new generation of numerical models that simulate lahar flow for hazard assessment at Cotopaxi. [ABSTRACT FROM AUTHOR]
