Landscapes: In contrast to topographical maps which are schematic renderings of spatial information, landscapes are cacophonic environments, the noisy ground of everyday life, memory and imagination. The Gabčikovo–Dam (built between 1977 and 1992) was built to control these mundane flows.

Reduction of Forms: Landscape transformation technologies use topographical visualizations (e.g. topographic maps, contour lines, elevation profiles, cross-sections and technical drawings) to study natural landscapes. These visualization methods reduce the elements of a complex environment to calculable forms and measurements.

Photogrammetry itself is one of the technologies that supports the extractive logic that compels the land to be transformed. In order to understand relations between objects in environments, photogrammetry is working from photographs taken around objects and it builds point clouds; by connecting those points a wireframe or topology is created. Cross-sections depicting the topographical features of the landscape around the Gabčíkovo-Nagymaros Dam were used to create these photogrammetric expressions.

The 3D model is the output of the photogrammetry process. It is also the evidence that photogrammetry has failed to identify an ‘object’ on the imported images, instead it created one.
