Psyttaleia
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.
