Mapping the Mahram Bilquis Marib, Yemen
The site was mapped using a total station and RTK-GPS.
The survey data was then downloaded into AutoCAD with the SurvCADD module and a Triangular Irregular Network (TIN) was generated with the Quicksurf module.
PhotoModeler was used to solve the focal length and camera locations for site photos taken from a helicopter.Photos with control points in PhotoModeler
