MapInfo_L, When using the CENTROID(x) CENTROID(y) function within SQL SELECT what coordinate system and datum are the query result return as. More specifically in my situation I have points plotted from UTMNAD27/83 and/or MTMNAD83 (various zones) coordinated systems all in the same window all plotted on top of a Generic Lat/Long map window. From here the CENTROID(x) CENTROID(y) function was used to create Lat/Long coordinates in decimal degrees. After all this I don't know what datum these points are in Nad27 or Nad 83. How can I determine this? If anyone can provide any information regarding this issue please let me know.
