[Qgis-user] Why QGIS change the SRS?

[Rafa García Castillo]

  Thanks Alexandre for answering. Yes, those projections are quite similar,
but one is in UTM coordinates and the other is TM. I can imagine that the
use of both projections is the same in most of the cases, but makes me
wonder why QGIS does this change, because they have different EPSG code.

  Thanks again.
