Grid lines and tics on a map don't necessarily bear any relation to the actual projection used, so don't count on that.
Googling romania stereographic 70 led me to http://www.geocities.com/mapref/prj/rm/rm.html which shows: Stereographic 70; Krassowskij-Ellipsoid; System42 ________________________________________ Projection TRANSVERSE Zunits NO Units METERS Spheroid KRASOVSKY Xshift 0.0000000000 Yshift 0.0000000000 Parameters 1 /* Projection type < 1 | 2 > 6378956.594 /* radius of the sphere of reference 25 0 0.000 /* longitude of center of projection 46 0 0.000 /* latitude of center of projection 0.000 /* false easting (meters) 0.000 /* false northing (meters) ________________________________________ It's odd that the word "Transverse" is stuck on a projection labeled "stereographic". Perhaps they mean Transverse Mercator (i.e. misusing "stereographic" to mean "conformal") or perhaps a rotated stereographic (i.e. you have to experiment with the Azimuth parameter in MapInfo) HTH Spencer ________________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ian Farrelly Sent: Thursday, July 27, 2006 4:03 AM To: [email protected] Subject: [MI-L] Romanian Projection Systems Hello All, I am having trouble trying to deal with some maps in a Romanian projection. I am unsure of the projection system (as it is not identified on the map) but have been advised that the maps are of a vintage consistent with the use of Stereo(graphic) 70. However, what little information I can dig up about this projection suggests that the base unit is in metres whereas the hard copy maps have grid lines in lat/long (degrees/minutes/seconds). Has anyone come across Stereo 70 previously or indeed have a projection description which I can insert into the Mapinfo.prj file. Im told that ArcGis has a Stereo 70 projection capability. Possibly someone has used the ArcGis projection parameters to develop a MapInfo projection. Any help would be great!
