Hello yesterday I downloaded the srs.db from Qgis SVN, I was looking for the new Italian srs added some days ago.
It seems to me that there are errors into the proj parameters: *) For Italy Sardinia the "towgs84" is repeated twice. *) Somewhere there are spaces after the decimal dot and after the minus sign *) For Sicily I have a different "towgs84" formula, which is: +towgs84=-50.2,-50.4,84.8,-0.690,-2.012,0.459,-28.08 Please can someone confirm that before I open a ticket? Here it is what I read from the srs.db: SELECT srs_id, description, parameters, epsg FROM tbl_srs WHERE srs_id >= 3640 AND srs_id <= 3643; 3640|Italy mainland zone 1 GB Roma40|+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl +units=m +towgs84=-104.1,-49. 1,-9.9,0.971,-2.917,0.714,-11.68 +no_defs|40000 3641|Italy mainland zone 2 GB Roma40|+proj=tmerc +lat_0=0 +lon_0=15 +k=0.9996 +x_0=2520000 +y_0=0 +ellps=intl +units=m +towgs84=-104. 1,- 49.1,-9.9,0.971,-2.917,0.714,-11.68 +no_def|40001 3642|Italy Sardinia GB Roma40|+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl +units=m +towgs84=-104.1,-49.1,- 9.9 ,0.971,-2.917,0.714,-11.68 +towgs84=-168.6,-34.0,38.6,-0.374,-0.679,-1.379,-9.48 +no_defs|40002 3643|Italy Sicily GB Roma40|+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl +units=m +towgs84=-168.6,-34.0,38.6,-0 .374,-0.679,-1.379,-9.48 +no_defs|40003 -- Niccolo Rigacci Firenze - Italy _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
