kokuda / gpxviewer Goto Github PK

The current version isn't compatible with v3 of the maps API. I've updated it 
in a repository hosted at GitHub: http://christopherpeplin.com/posts/gpxviewer/

What steps will reproduce the problem?
Use GSPBabel to merge two or more GPX files togther.

FoxTrot/Tango GPS will open the merged output file perfectly, but gpxviewer 
just loads the correct map location, with no track info at all - ie no track is 
drawn.

What is the expected output? 
a track to be drawn.

What do you see instead?
Nothing.

What version of the product are you using? On what operating system?
The Latest with the google v3 mod.

Please provide any additional information below.
I don't know enough about the XML side of things, but this clearly won't load 
any GPX files generated by GPSBabel. 

Keep up the good work ;)

Hi,

I have found a small error in file loadgpx.4.js
(http://okuda.ca/googlemaps/loadgpx.4.js).
The error occurs in Internet Explorer with test file lewis_clark.gpx
(http://www.travelbygps.com/guides/lewis_clark/lewis_clark.gpx).
In function CreateMarker empty nodes are ignored by testing for nodeType =
1 (elements only).
However, an elemement "link" may still have no children, such as in
lewis_clark.gpx:




In that case, firstChild is null and an error occurs (firstChild.nodeValue).

To capture this exception, an extra test is needed:

115     // Ignore empty nodes
116     if (children[i].nodeType != 1) continue;
117     if (children[i].firstChild == null) continue; // ";

bye,

I have a suggestion to show a popup when the user clicks on a track point
with the details (lat, lon, etc.).

This would most likely best be done by handling the click event and finding
the closest track point to that location.  This may not be practical in
Javascript, but it is an interesting idea.

It would probably require storage of the track points in a more efficient
format for finding the nearest point, but even a brute force methods might
work a small enough set of points.

Well, this is not actually an issue; I'm searching for a better way for 
this : I have several maps to display so I use a XML renamed GPX file per 
map of course and also one HTML file per map; the "issue" is that all 
these HTML files are identical except the name of the XML file they call.
My question : how can I invoque an unique HTML file passing to it the XML 
file as parameter ?
This is how I call the mal
<TD WIDTH="10%" VALIGN="MIDDLE"><P ALIGN="CENTER"><a 
href="Itineraires/080802.html">GPX</a></TD>
and in attatch the invoqued HTML

Thanks a lot in advance

I discovered a minor bug in the javascript file, on line 240:
       if ( (minlat == maxlat) && (minlat = 0) )
This is the correct:
       if ( (minlat == maxlat) && (minlat == 0) )
