One option is to create "virtual fields" in QGIS with the correct
field names "name", "cmt" ... and give these virtual fields the
relevant content. <br>
However the export to gpx will fail if you specify
-gpx_use_extensions=<b>no</b>, because the original field names
doesn't fit the schema definition for GPX. This will cause an error
message and the data won't be created<br>
<br>
To sum it up:<br>
<ol>
<li>Use virtual fields in QGIS to create fields and values that's
acceptable for GPX</li>
<li>use_gpx_extension has to be set to "yes"</li>
<li>Remember to save your GPX data in the EPSG:4326 projection
(ll/wgs84)</li>
</ol>

<pre>Hi list,
i already read a lot of post about exporting layer in another format using
"save as " windows of QGIS with adding ogr2ogr options (in data source box
or layer box down the windows).
the trouble is the same that a lot of people : i "only" want to export a
layer shape in a layer GPX
1) of course i could only use GPX_USE_EXTENSIONS = YES and all my fields
would go into the <extension>
xml;
But... it is not what i need. i really need to have the fields "name" and
"cmt" as they exist in the real gpx structure !
2) so, how to rename my field "testfield" to a field called "name" so as to
respect GPX syntax ?
in the data source option i try many many many syntaxe :
-sql "SELECT testfield AS name FROM testlayer" (this is ogr2ogr
documentation...)
-sql "SELECT testfield AS name"
sql "SELECT testfield AS name FROM testlayer"
"SELECT testfield AS name FROM testlayer"
'SELECT testfield AS name FROM testlayer'
Etc... But it never works !
i also try some syntaxe using the -dsco option but no more succes !
so, is it possible to use ogr2 ogr option ?
another thing : there use to be a samll GPX plugin to do that, we could
choose the field for name etc. ( i don't talk about gps extension with
gpsbabel)
is this plugin still exist ? theis plugin in was made with ogr2ogr i think,
so what not to use ogr2org option directly ans asked here ?
thanks a lot.
Thanks for helping. So long
