In this project was carried out an aerial photography by the use of an Unmanned Aerial Vehicle (UAV) in order to create orthophotomaps of 5 cm/px resolution, along a railway line within the preliminary study of its restoration and upgrading. For the 88 km long and 350 m wide of the railway line, 28 flights were realized and a total of 3383 images was taken. Approximately 200 ground control and check points were applied from surveying, in order to achieve a 15 cm accuracy.
