Description
NATS 1840 Lecture 22 - Nature Resists Commodification and Technology Fights Back: Aerial Surveying and Mineral Resources - Natural resources as fiscal tools for the state, technological extraction of natural resources, treating resources in a single way, private and public development of resources Geography Gets in the Way - Canadian Shield approximately 8,000,000 square kilometers of Precambrian rock, meteorite impact craters, extinct volcanoes, minerals: nickel, gold, silver, zinc, sulfides, diamonds and copper, southern reaches covered in forests - The shield is marked by, “…rolling, rocky hills, muskeg bogs, and innumerable lakes, rivers, and creeks”, difficult to traverse, large size - 1920’s Canadian mining companies adopted plane for surveying - Post WWI economic slowdown, aerial surveying techniques (interpretation of aerial photographs) - Government (Royal Canadian Air Force and Department of the Interior) dedicated resources to techniques - Canadian mining industry and Canadian government, method for transforming aerial photographs into geological data, speed and efficiency over accuracy - Approach common to Canadian technology, “national style” of developing technology, “…concern with practical application, collection of economically useful information, reliability, useable results, and speed above accuracy.” - Canadian approach to technology, political attitudes to science and technology, conditions of Canadian geography - Technological development associated with frontier technologies, as Cronin puts it, o “…those technologies that exist at the point where a technologically developed infrastructure meets the wilderness and an established society meets a new environment. Neither the American nor Canadian frontiers were uninhabited, nor were they void of preexisting technologies. Rather, those frontiers represented the points at which the established European-based industrial society met an environment not yet integrated into the dominant society.” Photography and Mapmaking - Photography recent development (19 century), application to surveying and mapmaking - Photography from places of high elevation, topographic maps - Orthographic projection, representing a three dimensional object in two dimensions - WWI aircraft survey enemy positions, ranges and positions for artillery - Scientific interest in Canadian north, “…information that would help them administer, control, and assert ownership over the land and its resources” - Mapping Canadian north and elevation - Late 1920’s aerial surveyors could “identify geological types from the air”, geological types correlated with minerals - Photographs not sufficient, photograph quality, techniques for interpreting photographic evidence - Aerial surveying: faster collection of information, greater area covered in less time - Numerous bodies of water, landing strips for floatplanes - Aerial surveying did not replace ground investigation, expanded scope - Accuracy of aerial pho
