CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishRectification of satellite imageries is typically conducted by means of UTM (Universal Transverse of Mercator) representation. In several applications on Marine GIS (Geographic Information System) nautical charts are used as cartographic bases, so to introduce satellite images, automatic conversion from UTM to Mercator is to apply. The aim of this paper is to remark the possibility to rectify high spatial resolution satellite imageries such as SPOT 5 with GCPs (Ground Control Points) that are referred to Mercator representation. To identify limits and benefits of this approach, results of application on SPOT 5 imagery concerning the Gulf of Naples are presented and discussed. To apply RFs (Rational Functions), GCPs were identified in airplane photos already rectified and georeferred in UTM – WGS84 plane coordinates: these values were converted in Mercator – WGS84 plane ones and used to rectify the SPOT 5 imagery.

| Abstract: | Rectification of satellite imageries is typically conducted by means of UTM (Universal Transverse of Mercator) representation. In several applications on Marine GIS (Geographic Information System) nautical charts are used as cartographic bases, so to introduce satellite images, automatic conversion from UTM to Mercator is to apply. The aim of this paper is to remark the possibility to rectify high spatial resolution satellite imageries such as SPOT 5 with GCPs (Ground Control Points) that are referred to Mercator representation. To identify limits and benefits of this approach, results of application on SPOT 5 imagery concerning the Gulf of Naples are presented and discussed. To apply RFs (Rational Functions), GCPs were identified in airplane photos already rectified and georeferred in UTM – WGS84 plane coordinates: these values were converted in Mercator – WGS84 plane ones and used to rectify the SPOT 5 imagery. | |
