Hi I am trying to load image on google maps. Here is what I get:
red square - what I see.
green square - what I want to see. I want to zoom to green square after map loads, but I cant manage to do that, any help?
Code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
</head>
<body>
<div id="map" style="width: 800px; height: 400px;"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 2,
center: new google.maps.LatLng(0, 0),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(-90,-180),
new google.maps.LatLng(90,180));
var oldmap = new google.maps.GroundOverlay("http://www.dxatlas.com/HamCap/3Y0X/20UT-21MHz.gif", imageBounds);
oldmap.setMap(map);
oldmap.setOptions({opacity: 0.5});
map.fitBounds(imageBounds);
</script>
</body>
</html>
I want to zoom to overlay layer that map would look nice like green square shows, it looks like "map.fitBounds(imageBounds);" doesnt work...
Any ideas?
This may be the nature of Google Maps v3; bounding extent is out of range at -180 to 180, modifying longitude to 179.9999. Ensuring image bounds is within Google Maps global extent may solve problem.

Some code demonstrates the issue:

var map = new google.maps.Map(document.getElementById('map'), {

center: new google.maps.LatLng(30, -97),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var viewportBox;
google.maps.event.addListener(map, 'idle', function(event) {
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(-90,-179.999),
new google.maps.LatLng(90,180));
var oldmap = new google.maps.GroundOverlay("http://www.dxatlas.com/HamCap/3Y0X/20UT-21MHz.gif", imageBounds);
oldmap.setMap(map);
oldmap.setOptions({opacity: 0.5});
map.fitBounds(imageBounds);
var bounds = map.getBounds();
var ne = bounds.getNorthEast();
var sw = bounds.getSouthWest();
var viewportPoints = [
ne, new google.maps.LatLng(ne.lat(), sw.lng()),
sw, new google.maps.LatLng(sw.lat(), ne.lng()), ne
];
if (viewportBox) {
viewportBox.setPath(viewportPoints);
} else {
viewportBox = new google.maps.Polygon({
path: viewportPoints,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 1
});
viewportBox.setMap(map);
};
var info = document.getElementById('info');
info.innerHTML = 'NorthEast: ' + ne.lat() + ' ' + ne.lng() +
'<br />' + 'SouthWest: ' + sw.lat() + ' ' + sw.lng();

I'm trying to create an encoded polyline of all Canadian provinces. I begun with this utility:
https://developers.google.com/maps/documentation/utilities/polylineutility
Using it I create many point to follow the province line of ontario as closely as possible. Here's a screenshot of the resulting polyline:
but when I take the polyline an plug it into the code to map it, It provides me with partially different line:

Any Ideas why the line deviates? I tried it twice, each time the line veers of midway.
Thanks
You need to escape the "\" characters in the string (replace the single "\" with a double "\\").
Change:

I am attempting to get a Google maps GroundOverlay working without luck. Searched everywhere, read the Google reference documentation, still no lucK.
What I have attempted can be seen at:

You can see that some sort of overlay is placed on the map. I believe I have the sw, ne latlng correct. If I check on Google maps by right clicking and choosing "whats here" those are the latlng that is given.
I have the overlay in png, gif and jpeg. With the png and gif I get nothing to appear.
Where have I gone wrong?
thanks
Ken
Your bounds is wrong for your groundOverlay.
according to the documentation for the constructor for a google.maps.LatLngBounds object:
Constructor
LatLngBounds(sw?:LatLng, ne?:LatLng) Constructs a rectangle from the points at its south-west and north-east corners.
The arguments should be SW, NE. Your arguments are SE, NW. Your code:
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(-38.374615, 144.823766), //SE
new google.maps.LatLng(-38.373628, 144.821631) //NW
);
If I swap the longitudes between the two points it works:
var imageBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(-38.374615, 144.821631), //SW
new google.maps.LatLng(-38.373628, 144.823766) //NE
);

I am following a tutorial that can locate a friend (their mobile) and pinpoint them on a Google map. All was going well including getting my coordinates and printing them to screen and putting them inside my <div id="location"></div> but now I am trying to take those coords and mark them on a map but I cant get the map to show. I'm sure my functions are set up wrong somehow but I can't work it out. Any clues?

I have tried passing div in CreateElement() method and then assigning the values to a variable mapcanvas. This whole declaration is inside a method which is called in this particular line:
navigator.geolocation.getCurrentPosition(success);
I am sharing the whole code..
<script>
function success(position) {
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcontainer';
mapcanvas.style.height = '400px';
mapcanvas.style.width = '600px';
document.querySelector('article').appendChild(mapcanvas);
var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var options = {
zoom: 15,
center: coords,
mapTypeControl: false,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("mapcontainer"), options);
var marker = new google.maps.Marker({
position: coords,
map: map,
title:"You are here!"
});
}
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success);
} else {
error('Geo Location is not supported');
}
</script>
Hope this would help!!!
I have never worked with Google maps API.
For the school project I am working on; I need to get a direction between two locations (this is easy part and I think I can do this),
However I also need to put an X mark; at every 10 miles along the way.
Is this even possible?
Thank You.
Ok, here's a working solution that draws markers every 200 miles (I was working on big distances to check it worked on geodesic curved lines, which it does). To make this work for you, just change all the coordinates, and change 200 to 10

For some reason the getBounds() function for Google Maps v3 seems to be extending much further than what the map is actually showing. Correct me if I'm wrong, but shouldn't it return the NE (top right corner) and SW (bottom left corner) latitude and longitude coordinates for the very corners of what's being shown in the current view?
I'm returning search results (which are mapped by a lat and lng) that are between these coordinates and am being returned results much further outside the area returned by getBounds(). Any ideas about what could be going on here?
Just FYI, I'm getting the bounds on the map's idle event:
google.maps.event.addListener(map, 'idle', function() {
var bounds = map.getBounds();
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
...and using .lat() and .lng() to get the coordinates from the respective corners. Then I feed that to a SQL query that checks for results between those coordinates. Results are in the general area but can fall far outside what's actually being shown on the map.
Any ideas are appreciated! Thanks!
Correct, the map.getBounds() will return the bounds of the viewable area, as shown in the example below. In this example, a red Polyline box is drawn using the points of map.getBounds() when the idle event fires.
Your SQL query might not be returning the results you are looking for, and may need looked at again.
