<DIV><FONT size=2 face=Arial>As a non-expert newcomer to QGIS I would most
grateful for the forum's advice.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I have the task of taking TAB and JPG files created
by a client in Mapinfo and drawing on them vector items using QGIS - and
then returning the resulting SHP files (or SHP converted to Mapinfo MIF/MID
files) to the client. When I do this, however, the client declares that,
the CRS for the resulting SHP or MIF/MID files are non-existent or
wrong.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>For example, Mapinfo TAB and associated
JPG files was sent from my client. If I look at the TAB
file in Notepad, I see that the data are as follows:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>!table<BR>!version 300<BR>!charset
WindowsLatin1</FONT></DIV>

<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>When I open the JPG in QGIS, I see that the CRS for
the JPG is 'User Defined' and has the following definition:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV>+proj=tmerc +lat_0=49 +lon_0=-2 +k=0.9996012717 +x_0=400000 +y_0=-100000
+ellps=airy +towgs84=375,-111,431,-0,-0,-0,0 +units=m +no_defs</DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial><EM><STRONG>At this point, I'm not too sure whether
or not QGIS has correctly interpreted the CRS for the Client's JPG. Can
anyone help me on this please?</STRONG></EM></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>When I create a SHP vector layer on top of the JPG,
I make sure that it has the same 'User Defined' CRS as above and save the SHP
layer as Mapinfo-useable MIF and MID files. Looking at the MIF file in
Notepad, I can see that the coordinates (shown bottom right in QGIS) of the
vector file agree exactly with the original JPG raster.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>When the MIF/MID files are opened by my Client
however, the files are unusable because the CRS is 'non-existent or
wrong'</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial><STRONG>Can anyone point out where I'm going wrong
please?</STRONG></FONT></DIV>
