Testiranje in izboljšava horizontalne datumske transformacije: študija primera v Bosni in Hercegovini (= Evaluation and improvement of horizontal datum transformation models: a case study of Bosnia and Herzegovina)
This study evaluates the applicability of different models of coordinate transformation between local and global geodetic datums. The results indicate the grid-based method as the best solution, assuming a sufficient density of tie points. Transformation based on a limited number of tie points, whic...
