Google Maps, anyway to plot a shape using the lon/lat values?

[MrRalphMan]

Is there anyway to plot a shape using a set of lon/lat points?

I've done a quick search but cannot seem to find an api to be able to do this.

 

Cheers,

 

Paul.

Check out:

 

http://code.google.com/apis/maps/documentation/overlays.html

 

GPolyline - Drawing Poly lines into a layer may be what you are after?

 

e.g. from the above:

 

var polyline = new GPolyline([

new GLatLng(37.4419, -122.1419),

new GLatLng(37.4519, -122.1519)

], "#ff0000", 10);

map.addOverlay(polyline);

 

Edit:

Actually just about any of the drawing stuff below that point looks cool... might start playing with that myself :D:D

 

Cheers,

 

Si.

Thanks, looks like it's exactly what I needed, worked in work, but at home I don't see the overlay.. That's on two PC's...

 

Can anyone else see the overlay here?

 

If so can you place the following code in a HTML file and open it in your browser.. Then maybe attach a screen shot of the map and overlay?

 

Cheers..

 

Paul.

I had to zoom out a bit to find where the polygon had ... gone I am sure there is a joke in there somewhere.

Edit: p.s. I meant to mention MacOS 10.5.4 using Firefox 3.0.1.

Edit2: p.p.s Looks to work on Firefox 3.0.1 on WindowsXP and also IE 7.

[MrRalphMan]

Thanks dude, no joke there. I'm trying to debug some ..... err .... issues with the Speed Camera detection for GPS Speedo..

[arvind8811]
