hi, > but is it a bug? or am I missing the good reason why there is this factor > 100?
I searched the source code to find the reason why there is a x100 on coordinate, but couldn't find where it's done. But my guess is that for performance reasons, the field to store x/y was chosen to be an integer instead of a float. And because rounding a spherical mercator to the unit would loose sub meter precision, it was stored as multiplied by 100 for ~cm accuracy -- sly qui suis-je : http://sly.letuffe.org email perso : sylvain chez letuffe un point org _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
