Topographic Survey
Athens, Greece 2017-18

Using photogrammetry, over 1300 high resolution photos allowed us to aquire a ground resolution of 2 cm/pix over an area of 90 hectares. This resulted in an equally detailed topographic model, that was subsequently downsampled to a 10 cm raster resolution.

On top of the topographic model, roads, buildings and vegetation was measured and drawn to complete the survey.
