Verification of the Wołek Castle Model with the Actual State Using Digital Photogrammetry and Conventional Survey Methods

This paper presents the results of a study to assess feasibility using Structure from Motion photogrammetric method estimate what parts Wołek Castle have survived 15th century present day. The measurements were made with Nikon D5200 camera, and 249 mock-up images obtained. Planimetry altitude coordinates castle ruins obtained RTN GNSS polar method. in 2000 coordinate system zone 6, heights Kronstadt system. Two spatial models made. first one field scale was ground control points measured terrain. second on model local measures analyzed, compared actual orthophotomap, it estimated part preserved reality.
