I discovered a very strange behavior of MapInfo: I have two tables with a single point in them, first is in CoordSys Earth Projection 1, 0 second is in CoordSys Earth Projection 1, 9999, 10, 589, 76, 480, 4, 2, 3, 1, 0 In both tables the point has the same coordinates: 18.519163,48.52017 When I place both the tables into a single mapper, the points perfectly overlay. But when I change the projection of the mapper to CoordSys Earth Projection 8, 1001, "m", 21, 0, 1, 4500000, 0 Bounds (-3749281.53901, -10002137.4978) (12749281.539, 10002137.4978)
or save copies of the tables with this projection, the coordinates (in meters) are different! First table: 4316739.3,5379336.0 Second table: 4316791.2,5379340.9 The distance of the points is 52 meters then! The first pair of coordinates seems to be more close to the reality. I haven't tested it with other projections, so I don't know whether it is related only to discussed ones or other too.
Please help!
