<p class="MsoNormal">Hello All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am currently using GDAL 1.9 and I’m writing out GPX files for uploading onto Garmin units. Garmin has many different GPX extensions (gpxx, gpxtpx, gpxtrx, etc) for defining extra attributes for their GPS data. I am wondering how I would
specify these multiple extensions in my code? Currently, I am defining a single extension as shown below:
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:9.5pt;font-family:Consolas">ds = drv.CreateDataSource(outputFilePath,
<span style="color:blue">new</span> <span style="color:blue">string</span>[] { <span style="color:#A31515">
"GPX_USE_EXTENSIONS=YES"</span>,<span style="color:#A31515">"GPX_EXTENSIONS_NS=gpxx"</span>,<span style="color:#A31515">"GPX_EXTENSIONS_NS_URL=http://www.garmin.com/xmlschemas/GpxExtensions/v3"</span>});}<o:p></o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><o:p> </o:p></p>
<p class="MsoNormal" style="text-autospace:none">How would I go about setting more namespaces (gpxtpx, gpxtrx, …)? And then how would I specify that an attribute belongs in a particular extension?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
