The following site : https://developers.google.com/maps/documentation/javascript/customoverlays shows how to create image overlay using customoverlays but how do I use the same technique for creating polygons using customoverlays. The map that I am using comes from the following example http://gmaps-samples-v3.googlecode.com/svn/trunk/latlng-to-coord-control/latlng-to-coord-control.html . However, when I added polygons to the map, it is unable to display lat/long/pixel values when I moved the mouse over the polygons. I thought that if I created the polygons using custom overlays the problems will be solved. I have created image overlays using custom overlays and it is able to display the correct lat/lng/pixel values when I moved the mouse over the image. Therefore I think if I create the polygons using custom overlays, it should work also but I could not find examples on how to do that. Please advise.
Updated Code:
aoiPoly = new google.maps.Polygon({
paths: polyCoords,
strokeColor: '#FF0000',
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: '#FF0000',
fillOpacity: 0.35,
clickable:false
});
aoiPoly.setMap(map);
If you set clickable:false on the google.maps.Polygons, they will be prevented from intercepting the mouse events.
clickable | boolean | Indicates whether this Polygon handles mouse events. Defaults to true

I was looking at http://here.com/ and noticed that their controls navigation panel has a zoombar.
I was wondering if this is a map setting or is it something that needs to be custom built.
Posting it here due to lack of a better suited forum.
A zoombar can be added to a map using the HERE Maps API for JavaScript as shown:
var map = new nokia.maps.map.Display(mapContainer, {
// initial center and zoom level of the map
center: [52.51, 13.4],
zoomLevel: 10,
components: [
new nokia.maps.map.component.ZoomBar()
]
});
The zoombar looks like this:
The zoom control on here.com looks like this:
It is a custom map control and would need to be created with your own code using the UI library of your choice and creating a new class extending MapComponent.
An outline sketch of how to go about this can be found in the question here
This one has me stumped, and I'm hoping a second set of eyes will be able to point out the problem. I realize that my abstraction library adds a lot of additional complexity, but I was thinking that someone else may have seen something similar in their implementation. I've also tried to boil this down to as simple and targeted a case as possible.
The problem is that markers created and added to the map via the Google Maps API and set as draggable cannot be dragged. This used to work just fine, but a change I made somewhere in the library broke this functionality. To reproduce, go to http://www.nps.gov/npmap/support/library/examples/map-defaults.html?api=google and then paste the following code in the browser web development console:
var marker = new google.maps.Marker({
position: NPMap.Map.Google.map.getCenter(),
draggable: true,
map: NPMap.Map.Google.map
});
The marker should be draggable, but it is not.
A few notes:
Markers are still clickable, and it seems like all marker events (mouseover, etc.) are working properly
Lines and polygons added to the map as editable work fine
I have played around with the z-index of the map div and some of the other elements, but this doesn't seem to be causing the problem
I am loading the current release version of the Google Maps API, v3.11. I have tested with the frozen version, 3.10, and the experimental version, v3.12, but the problem persists no matter which version is loaded.
Any help is greatly appreciated!
UPDATE: Strange. Markers added with draggable: true don't appear to be clickable. But if a marker is added without specifying draggable: true, it does seem to be clickable. It seems like this is probably related.
UPDATE 2: A follow up to my first update: Events are not working on markers that are created with draggable: true and added to the map. You can run the following code after creating the marker to test this out:
google.maps.event.addListener(marker, 'click', function(e) {
console.log(e);
});
Figured it out. I was doing something like this to hack around some of the default Google Map controls:
var els = document.getElementsByClassName('gmnoprint');
for (var i = 0; i < els.length; i++) {
els[i].style.display = 'none';
}
This hasn't affected draggable markers in the past, but Google must have made a change in the Maps API and started adding the gmnoprint class to draggable markers. Oh well, that's what I get for going outside of the documented API.
I am developing a custom imagemap type map without geo referencing i.e. latlng of my map do not relate to acutal latlng of that place. Now i have also created custom streetview panoramas of certain buildings and places in that map.
The issue is am not able to integrate those custom streetview panoramas with my custom imagemap.
Following is the link to see whats going on:
http://cdi.astateweb.org/virtual_tour/
First Approach:
There are two markers on the map right now. When you click on them a small infobubble pops up. Now when you click on the virtual tour link a dialog comes up. I want to load the custom streetview panorama in that dialog. I tried several things but to no avail. I am trying to reuse the same dialog for both markers. I tried initializing the panorama in jquery ui dialog open function. It worked for the first one but when you close the dialog and open it again it fails with some cbk error from google apis.
SECOND APPROACH:
I tried to use the default streetview pegman such that when the pegman is dropped on a certain building or place which has a panorama the streetview comes up just like in normal google maps. This didn't work either.
Can somebody point me to the right direction. Any help will be highly appreciated.
Thanks
Ok, try like this:
Change at line 41
from
'Virtual Tour'
to
'Virtual Tour'
Change at line 96
$("#dialog").dialog({
autoOpen: false,
width: 650,
open: function() {
console.log($("#" + virtualTour.currentPano));
$("#" + virtualTour.currentPano).appendTo("#dialog").css("display", "block");
},
close: function() {
$("#" + virtualTour.currentPano).appendTo("body").css("display", "none");
}
});
And the below code to add into "createMarker" function.
//After this line.
virtualTour.hotspotArray.push(marker);
//Add this code.
setTimeout(function(){
document.getElementById(pano).style.display = "none";
}, 100);
When I visit http://maps.google.com on my iOS device, the current location is shown as in the image below.
I'm creating my own Map using the Google Maps API v3. How can I create this function?
I've tried their sample using geolocation in the web browser but it just displays an text box on my location. I would like it to be similar to the image above, where is it shown using the blue markers and a circle showing the accuracy. Is this default behavior if Google Maps API v3 or should I design it myself using an icon, marker and circle?
You can set the marker image by setting the icon property of the MarkerOptions object passed into the Marker constructor to show a custom image.
http://code.google.com/intl/da/apis/maps/documentation/javascript/reference.html#MarkerOptions
var marker = new google.maps.Marker({
position: new google.maps.LatLng(56.8848, 14.7730),
map: map,
title: 'My workplace',
clickable: false,
icon: 'http://google-maps-icons.googlecode.com/files/factory.png'
});
Here is a site with some more information about using Google Maps API V3 http://www.svennerberg.com/tag/google-maps-api-3/
I am attempting to create our college campus map for our mobile website that will be launching shortly.
I have followed google's map api v3 example for creating a simple image overlay (found here: http://code.google.com/apis/maps/documentation/javascript/examples/overlay-simple.html) which I have successfully created.
However, my question is and what I am struggling greatly with is, how to place markers that show on top of this image overlay?
I understand how to make a marker on google maps, and attempted to implement it with the simple code of:
var myLatLng = new google.maps.LatLng(xx.xxxxx,-xx.xxxxx);
var marker = new google.maps.Marker({
position: myLatLng,
map:map,
title:"testing"
});
however placing that in the initialize section, causes the marker to fall under my custom image overlay... I read that I need to place it in one of the map panes that is greater then the 3rd pane, but this is where I would need some help, where to place this and how?
Markers always render in the overlayImage pane, so rather than trying to move the marker, move the overlay you added so that it appears in a lower pane (beneath the markers).
Replace:
var panes = this.getPanes();
panes.overlayImage.appendChild(div);
with:
var panes = this.getPanes();
panes.overlayLayer.appendChild(div);
That is, replace overlayImage with overlayLayer. The Maps API V3 Reference tells me is the pane that contains ground overlays, polygons and polylines (all of which appear below markers).
