Michael - You need to set the coordinate system explicitly to BNG when using eastings/northings in your program for calculations in the UK rather than lat/long (which is what you are defaulting to).
Look at Set Coordsys - the values for BNG are Set CoordSys Earth Projection 8, 79, "m", -2, 49, 0.9996012717, 400000, -100000 Paul Crisp Syntegra Innovation Place Delta Bank Road Newcastle NE11 9DJ Tel 0191 461 4522 Fax 0191 460 1987 -----Original Message----- From: CLARK, Michael [mailto:[EMAIL PROTECTED]] Sent: 15 August 2002 12:04 To: '[EMAIL PROTECTED]' Subject: MI-L RE: Grid References and Mapinfo I am having problems mapping a set of points in mapinfo. I have converted the point data from OS GRs to cartesian coordinates and are now in a table in mapinfo along with some other columns e.g. ID GR E N 1 SJ537916 353,700 391600 Where E,N are the coordinates. I've gone to table, create points, select E and N as coordinates but all I get is one point. Where am I going wrong?
