I have a google map displaying a polyline. I can detect mouseover events for the whole line, but I want to catch these events on the line-segment level. Is there a way to do this while still using just one polyline?
I think that is not possible since the google maps polyline object is really just one.

I am trying to make a Polyline editor, just like the one from Google Drawings Library. (for specific reasons, i can't use that one)
It works on the same principle. Start with a point, then for each click add new points and make the polyline.
On the editor from Google Drawings Library, while you are editing a polyline, you're mouse can't interact with other items from the map.
Inspecting with firebug, i see that they have an overlay of 20000000 z-index inside the map.
Is there any way of creating the same overlay for my map using default Google Maps functions?
It's a custom overlay inside the overlayMouseTarget-pane with the same size as the map and a draw-method that updates the position of the overlay. You may do the same.
I am making an application with google maps.
When markers are overlapping only the last one is displayed even if the icons are different..
I do not want it to cluster in that case, rather it should show both maybe by changing the coordinates just a but??
Any solutions??
I think this is a pretty elegant solution, called Spiderfying the markers.

I'm thinking of using it.
What I do now is use JavaScript to make a fancy popup that hides and shows divs on one marker location (created problematically in PHP, but you could do it on JS too). It has the side benefit of allowing less markers on the map.
Click a black numbered marker on this map to see it in action.

Another option is to use Google Maps API 3 Utility Library, it has a Marker Clusterer.
Is there any tool that can help me with getting the coordinates for a specific area/polygon?
I usually use Google Earth.
Draw a polygon, then move the mouse over and right click > copy.
Then you can paste it in the notepad and you will find the coordinates there (remeber the format (long, lat,n) the reverse of Google Maps format.
You can also use online tools to format the information or remove parts.

So the idea is to have a map, draw a polygon on it (I assume by placing the vertexes) and then getting the coordinates of the vertexes?
You can make markers draggable when you create then. You can also get the lat/lng position of the markers when certain events fire: the 'dragend' event, for instance.
With these tools, you have the basics of your requirements here. Make a button that places vertexes on the map - just use a marker with custom graphics - and let the user drag the vertex to whatever position they need. Record the new position of the vertex whenever the dragend event fires. Draw lines on the map between the markers, to show to the user the area selected. Have a button to 'complete' the shape, linking the last vertex up with the first vertex.
There may be some existing code to do this, but I am not aware of it. However, it should be possible to throw something together with a bit of work.
i'm creating a simulation model using Google maps, i have created a new KML layer and marked few areas which are dangerous to users to go through, now i want to add a moving object to resemble a person on top of it and give a warning when that object nearing the area, does any one have the idea of doing animation of that kind using Google maps?
If you are talking about a moving marker i think you can use the setPosition of the marker object in a for loop feeding it with the coords of a line let's say.
I am wondering how I can create two markers on a google map (upon click) and have a line drawn between them. Ideally both markers would be draggable after they are initially dropped and the line would readjust accordingly.
Maybe you can check this example, though is already deprecated it might help you to get an idea
