Hi Duncan,
I have tinkered with the API previously - the xml import is.. 'ok'.
Too many points (in the form of a polyline) and it will crash Safari
and if i remember correctly firefox too, it works fine on IE as IE
uses a different method to draw the polylines (VML).
You can be dirty and throw a complete unedited gpx file at it -
(convert your gps file to gpx - its the best standard for them, google
gpsbabel):
var request = GXmlHttp.create();
request.open("GET", "http://www.coolreflections.co.uk/gmaps/tracks6.xml";, true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = request.responseXML;
var markers = xmlDoc.documentElement.getElementsByTagName("trkpt");
var points = []
for (var i = 0; i < markers.length; i++) {
points.push(new GPoint(parseFloat(markers[i].getAttribute("lon")),
parseFloat(markers[i].getAttribute("lat"))));
}
map.addOverlay(new GPolyline(points));
}
}
request.send(null);
The xml file it imports is in the format:
<trkpt lat="51.582634" lon="-2.834516">
<ele>-13.801758</ele>
<time>2005-07-02T11:36:47Z</time>
</trkpt>
This is just a quick and dirty example almost straight from the documentation.
Regards,
