Dear all,
I am trying to create a map in python where I have a shape file in the BTM
projection system. I want to add OpenStreetMap as the base map under the
shape file. Can anyone suggest me how to change the coordinate system of
the map in python?
Regards,

If you import the text file as AGD84, then again as GDA94, there should

I agree with you on that...
Are you sure about the original shapefile projection? Does it have an

Sarel,
You certainly shouldn't have to save the shapefile to get the correct
projection... did you try refreshing the mapcanvas after enabling on the fly
projection (though this shouldn't be required either)?

Hi Magnus
I am using shapefiles. I had to save the shapefile with the new CRS to get
the projection correct and reload.

Hi Giovanni
Yes I have tried the OTF facility and still the layers wont overlay. The
issue is that changes can be made to the CRS but it does not take effect
until the layer file is saved with the new CRS values and is required to be
reloaded in a new session. Surely the layers should refresh with
Hi,
did you checked
"enable on the fly CRS transformation" in the properties of your
project?

Hi
Has anyone had to re-project layer files with different projections in
Quantum 1.0.2 ?
I have two layers,
1 - Geographic projected layer (WGS84) and an
2 - Unknown layer (meters is visible) so need to project to WGS/UTM-36S
After loading the two layers it was expected not to overlay. I change
Well, I did find out (by asking): the original .sid file (which I
converted to geotiff) did not contained any spatial/projection
information. No wonder!
Sorry for the trouble!

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?

Privet, Maxim —
I am not 100% sure, but I am reasonably certain: I got them from a
public Texas agency that provides spatial data (www.tnris.org). How do I
find out for sure?

Hi Mikhail,
Did you enable on the fly projection in the project properties window?
QGIS cannot reproject rasters on the fly, so you must set your project
projection to the same projection of your raster layer. QGIS will
reproject vectors on the fly.

Zoltan

Privet Mikhail,
Are you sure both shape and geoTIFF projections are assigned
correctly? I mean is data really in the projection you says it is?
