In this paper results obtained with automatic executions of datum and coordinates transformations using some GIS softwares are described: 43 points of IGM95 network within Campania Region, which are known in reference to UTM-WGS84 and Gauss-Boaga Roma40, have been considered; two vector files, one in UTM-WGS84 plane coordinates, the other in UTM-WGS84 geographic coordinates, have been produced.

To conduct additional analyses, for 43 considered vertices also UTM-ED50 coordinates have been calculated with Verto1 (IGM, 2002) and used as comparison terms for analogous ones derived from applications of above mentioned GIS softwares.

Abstract

In this paper results obtained with automatic executions of datum and coordinates transformations using some GIS softwares are described: 43 points of IGM95 network within Campania Region, which are known in reference to UTM-WGS84 and Gauss-Boaga Roma40, have been considered; two vector files, one in UTM-WGS84 plane coordinates, the other in UTM-WGS84 geographic coordinates, have been produced. Using softwares ArcGIS 8.3 (ESRI, 2002), Autodesk Map 3D 2005 (Autodesk, 2005), Idrisi 32 Release 2 (Clark Labs, 2002) and MapInfo Professional 7.0 (MapInfo Corporation, 2002), datum transformations (from WGS84 to Gauss-Boaga Roma 40) and coordinates transformations (from UTM-WGS84 plane coordinates to UTM-WGS84 geographic ones) have been applied; the results have been compared with values supplied by IGM. To conduct additional analyses, for 43 considered vertices also UTM-ED50 coordinates have been calculated with Verto1 (IGM, 2002) and used as comparison terms for analogous ones derived from applications of above mentioned GIS softwares. Datum transformations concerning plane coordinates have been applied using similitude (4 parameters: 1 rotation, 2 translations, 1 factor scale) in CAD MicrostastionV8 XM Edition (Bentley, 2005); in this case 4 points known in the different systems have been considered.
