Abstract
This paper describes the creation of new grids for datum transformation in the PROJ4 library, providing a technical insight of the implementation and use issues. The results obtained during their use in GRASS are reported. The grids used in this study were originally developed for the Italian territory, using data published in Bollettino di Geodesia e Scienze Affini for the transformations among ROMA1940, ED1950 and WGS84-ETRF89 datum.| File | Dimensione | Formato | |
