[Qgis-user] Re: Question about changing Project for Vector Layers

[Lenny Sorey]

Thanks for your response Giovanni.

OK, now I have the on-the-fly re-projection checkbox enabled in the project
settings.

I should mentioned that I am on the OSEGeo4w Windows nightly build version
of QGIS.

One thing I did notice when the options panel on-the-fly re-projection is
enabled is that the
the vectors appear now in in WGS84 with the lat/lon's I now recognized. But,
when I add
an Openlayer Google Satellite Hybrid plugin layer my WGS84  -90.15628,
32.43978 lon/lat display
at the bottom of QGIS turns into -10036151.0, 3821178.0 based on based on
google's EPSG: 900913.

I have never noticed the change in the lon/lat from -90.15628, 32.43978 to
-10036151.0, 3821178.0
before when re-projecting with the Openlayer Plugin.

Am I just missing something here?

Thanks,

Lenny
