Hello, could anyone help me with the following question (I am new to
Openlayers and I don't have much experience with Javascript)?
I build a map to embed in a webpage using the examples in the OSM pages
then I found examples on how to show a track with the following code
var lgpx = new OpenLayers.Layer.GML("GPS route", gpxfile, {
format: OpenLayers.Format.GPX,
style: {strokeColor: "red", strokeWidth: 5, strokeOpacity: 0.5},
projection: new OpenLayers.Projection("EPSG:4326")
});
map.addLayer(lgpx);
Up to here everything worked well but nOw I would like to complement the map
with markers that I calculated based on the tracks in the file: i.e. I want
a marker every km (I have many tracks for which I wish to do this). How can
I get the points in the gpx file in an array so that I can calculate
distances between them and then interpolate to find the coordinates where to
put the markers?
I appreciate any help
thanks
kps
