[Qgis-user] Projection question

[Mikhail Umorin]

Thank you for the suggestions, Zoltan —

Unfortunately, no luck. I enabled "on the fly" and set project's CRS to
WGS84 (same as the GoeTiff's) but no changes in the way they are
rendered in QGIS: different size and far from each other.

What else can I try?

Mikhail.
