All, apologies, I mistakenly attached the adjacent geo reference file (TFW) file which I have now corrected. Ill try your step by step Saber and see if that works.
Many thanks Ian ________________________________________ From: [email protected] [[email protected]] on behalf of [email protected] [[email protected]] Sent: 05 May 2012 17:00 To: [email protected] Subject: Qgis-user Digest, Vol 75, Issue 17 Send Qgis-user mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://lists.osgeo.org/mailman/listinfo/qgis-user or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of Qgis-user digest..."

Once you got that sorted, you need to ensure the CRS for the raster is set to the British National Grid (EPSG:27700). To do that, right-click on the layer, Properties, General tab and set the CRS to EPSG:27700 2- Set the canvas CRS to BNG (EPSG:27700) by going to (from the main menu) Settings > Project Properties ... CRS tab 3- When you add your GPS, select Lat as X field and Long as Y field. Please note that as default it's the other way round in the dialogue box. 4- Ensure the GPS layer loaded as WGS84 (EPSG: 4326) 5- Turn on the OTF and it should work.

Please > help :-) > Hello, as far as I can tell from your data, your rasterfile has a problem with its projection: The associated .tfw file you put online had the wrong name (the raster is named ST.tif, therefore the .tfw - file has to be named ST.tfw). So two questions to dig further: Is it the right .tfw file for that raster? And in which projection is the raster - in the .tfw file are just numbers, from which it is hard to guess for me, to which coordinate system they belong to... (UTM or a national grid...) Maybe for a little background, a look on wikipedia... http://en.wikipedia.org/wiki/Map_projection HTH, Albin ------------------------------ Message: 3 Date: Sat, 5 May 2012 01:58:43 -0700 (PDT) From: Nick Hopton <[email protected]> Subject: [Qgis-user] Re: Help: GPS data not showing in correct position To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=us-ascii Albin Blaschka-5 wrote > > as far as I can tell from your data, your rasterfile has a problem with > its projection: The associated .tfw file you put online had the wrong > name (the raster is named ST.tif, therefore the .tfw - file has to be > named ST.tfw). > > So two questions to dig further: > Is it the right .tfw file for that raster? > > And in which projection is the raster - in the .tfw file are just > numbers, from which it is hard to guess for me, to which coordinate > system they belong to... (UTM or a national grid...) > Hum, yes. The raster is for Ordnance Survey 100 x 100 km grid square 'ST' and the TFW world file is for square 'SU'. You need to find the correct world file for the raster (ST.TFW). Put ST.TIF and ST.TFW in the same directory and load ST.TIF. Right-click on ST.TIF in the layers panel and set its CRS to EPSG:27700, then set the project CRS to EPSG:27700 and enable 'on-the-fly'. The next problem is that the CSV file has its latitude column labelled as 'LONG' and its longitude column labelled as 'LAT' so fix this. Then load the CSV file. Here, the points plot near to Evercreech.
