Hi, I need to change a set of Eastings/Northings (British National Grid) into Lat/Longs, and although I know the actual process in MapInfo, the answers I get differ to those I get through the OS Website (using Co-ord converter).
Eg. Using the co-ords below the different answers I get are as follows; E529256, N178798 MapInfo - Lat 51.492847, Long -0.137903 OS site - Lat 51.49336039, Long -0.13948250 My query is, why the difference (am I using the wrong transformation?), and if so can someone explain what I should be using instead (is there any reading material out there so I can learn more). Thanks in advance, Sarah *********************************************************************************** The contents of the e-mail and any transmitted files are confidential and intended solely for the use of the individual or entity to whom they are addressed.
