All , yes Ive tried the "on the fly" setting but to no avail. I attch a link where I have uploaded the points, the mapping I am using and a google map plot the coords (which is right!). Any bright ideas please advise, I have some other data from another source where I have a similar problem. Please help :-)

Thanks

As I understand it all GPS data is recorded as decimal degrees within the WGS 84 geography. I recently recorded some data using my Android phone from site and also received some data from a colleague that when located on Google maps show up in the correct position, but when I bring the data into QGIS, to overlay with my mapping thats in OSGB (80) format they are completely located differently. Im sure I must be doing something wrong but I cant seem to sort it out.
Thanks
Ian

Hello,
have you activated the "On the fly reprojection"? (Project Properties,
in the tab where you choose the projection)
After having activated, you should again do a "Zoom to Layer" (in the
Panel on left side, right mouse click...)
HTH,
Albin

Hallo
Could your problem be related to my very strange GPS-problem?
http://gis.stackexchange.com/questions/24070/gps-problem-in-qgis
I have asked earlier here on list and on the link, but it seems like I
am the only one experiencing this.

Hi,
Some new observations I've made.
In the example I used yesterday, the raster input was float32.
I tested now with a Int16 raster input and found that the problems are even greater. On one hand, the rasters are coming out of the Grid Calculator float32. Secondly, the extent is always changed, and the resample is always applied, irrespective of whether an odd or even number of layers.
Screencast: http://goo.gl/A1ccn?
Using the SAGA GUI, the rasters are also converted to float32, but the Extent is preserved and the resample is not applied.
Screencast: http://goo.gl/ZJhnv?
I did these tests on Windows 7 and Debian Wheezy, with the same results.
If someone wants to try to replicate, the original data are from FaunaliaPT and Professor Gon?alves from University of Porto.

Best regards,

At the bottom of the Layers window, there is a "Control rendering order"
checkbox. If that box is checked, then it behaves as expected. If not,
well, it doesn't (you'll need to look at the Layer Order window.) Perhaps
the issue is that the checkbox is not checked (turned off) by default.
Probably it should be checked by default.
