Geodetic Monuments presents a series of images and video sequences based on the construction of survey markings by the NSW Land and Property Information Service. These structures are used by surveyors to determine, map and fix, locking all air and land into a vast lattice. The project originates from an ongoing interest in the exchange between individuals and their environment, how we mark via the monument and how the monument marks us. They are a consequence of our thoughts projected onto the land fusing the interiority of thought with the exteriority of matter. Geodetic Monuments is a thinking on the relationship between the idea of survey, the materiality of the survey marker itself and the possible histories that develop as a result of it.
