[Google Maps API v3] Level Switcher for Indoor Maps
Is there a way to show a level switcher for indoor maps in the JavaScript Maps API? I can't find an option to display floor plans correctly. On the website it says: … will also be available through the Google Maps APIs for use in your mobile applications or website. Maybe the feature was not released?

[Google Maps API v3] Re: Upcoming change: 3.10 becomes release version on November 15
Hey Enoch, one of our customers reported, that his app crashes after the API update. Is there a way to force the load of v=3.8? We use an older version of Webkit that is not compatible with the latest updates. Maybe there is a solution for business clients that use the Google Maps API internally.

Now look at the documentation for the Polyline:

I'm using OSMDroid: http://code.google.com/p/osmdroid/ It also lacks many features that the javascript API v3 has, but it's source code is available and you can (in theory) create whatever features you require.

[Google Maps API v3] Re: rightclick event inside a circle
Hi.
Could you add an API event listener for the Map 'mousemove' event:
http://code.google.com/apis/maps/documentation/javascript/reference.html#Map
google.maps.event.addListener(myMap, 'mousemove', function(mouseEvent)
{
lastMousePosition=mouseEvent.latLng;
});
lastMousePosition would have to be defined as a global variable in
your code.
Then add a DOM event listener for the mouse right click event.
Whenever the DOM event is triggered you will have the last mouse
position available.
Or does the API 'consume' the right click event so it will not
propogate to your DOM listener?

[Google Maps API v3] KmlLayers and Polygons
i seem to be going round in circles and cant find an answer to this. I'm adding a KmlLayer to a map, reading in a series of Placemarks (each of which contains MultiGeometry/Polygon) definitions.

Once the layer has loaded, colour some of the polygons (i.e. go through the polygons and set a fill colour for some) 2. when a click is performed, detect which (if any) polygon it is inside.

For click event it is more acceptable to absorb the click event for underneath overlays because you did not really click the underneath overlay if some other overlay is on top (if we let opacity out of the argument).

[Google Maps API v3] Re: How to add a domready event to an infoBubble
Hi.
It might be that the 'domready' event fires BEFORE your next line of
code which adds an event listener for that event.
(The event happens before you listen for it).
Try adding the domready event listener before opening the InfoBubble:
var infoWindow = new InfoBubble({content: request.responseText,
maxWidth: 1000, position: latLng, arrowSize: 0, maxHeight: 600});
google.maps.event.addListener(infoWindow, domready, function()
{load_rotator();});
infoWindow.open(map);

[Google Maps API v3] Re: ImageMapType issue?
Hi. Look at the documentation again in more detail. http://code.google.com/apis/maps/documentation/javascript/maptypes.html#MapTypeInterface Base Map Types Map types which you construct in this manner may either stand alone or be combined with other map types as overlays. Standalone map types are known as base map types. Overlay Map Types Some map types are designed to work on top of existing map types. Such map types may have transparent layers indicating points of interest, or showing additional data to the user. Image Map Types Note that this map type is inserted into the map's overlayMapTypes array. So you can create a standalone new map type or a map type that displays on top of other standalone map types. It sounds to me as if you want to create an OverlayMapType? Martin. On Nov 10, 6:19 am, Map Guy rclair...@gmail.com wrote: Good call about the BOM. Fixing that seems to have got me past some issues... I think I may be confusing Layers with MapTypes?

Hi.
Try something like this...
Create a global variable:

Add an event listener to your map, listen for the 'center_changed'
event:
google.maps.event.addListener(g_map, 'center_changed', function(){
// save the map center
lastMapCenter=g_map.getCenter();
});
Now listen for the map 'resize' event:
google.maps.event.addListener(g_map, 'resize', function(){
// restore the last saved map center
g_map.setCenter(lastMapCenter);
});

milliseconds during the resizing. I got the idea from StackOverflow

pre
function resize() {
if (g_map) {
var c = g_map.getCenter();
var that = this;

that.balancer = setTimeout(function() {

I've started a new thread for this subject - it follows on from this recent thread about MarkerImage and optimised Markers: https://groups.google.com/group/google-maps-js-api-v3/browse_frm/thre... I've run into a problem with optimised Markers and the Map mousemove event... Here's a project i've been working on: http://developer.martinpearman.co.uk/markers_event_layer/demo/index.htm and http://developer.martinpearman.co.uk/markers_event_layer/demo/index.h... I'm detecting click OR mouseover and mouseout events on all markers under the mouse - not just the top most marker. My first link is the mouseover and mouseout version, my second link the click version. Markers consume the Map click event so my single Map click event listener detects no Marker clicks unless you set the MarkerOption clickable to false. My code does this and it works as desired except i'd like the cursor to change when over a Marker - that doesn't happen when the MarkerOption clickable is false. http://code.google.com/apis/maps/documentation/javascript/reference.h... Anyway that demo defines a MarkerImage with a scaledSize set to the same size as the MarkerImage's size. If you read the thread i linked to you'll find that setting a MarkerImage scaledSize forces non-optimised Markers. So i changed my demo to pass null as scaledSize in the MarkerImage connstructor and thought that would give me optimised Markers and my existing code would still work but it doesn't. Optimised Markers by default consume the Map mousemove event so my demo's mousemove event listener never executes. Much like the demo's click event listener never executes unless the MarkerOption clickable is set to false. (Non-optimised Markers with MarkerOption clickable set to true (default) do NOT consume the Map mousemove event). Setting an optimised Marker's MarkerOption clickable to false stops the Marker from consuming the Map mousemove event and my code again works as desired - albeit with no change of cursor when over a Marker. Here's a simple map that demonstrates this behavior: http://developer.martinpearman.co.uk/markers_event_layer/mousemove_ev... On that map, Markers are optimised and clickable - both these options are the defaults. Move the mouse over a group of Markers and you'll see the Map mousemove event listener stops updating the mouse position top center of map. http://developer.martinpearman.co.uk/markers_event_layer/mousemove_ev... That map uses non-optimised Markers that are clickable by default and the Map mousemove event listeners executes even when the mouse is over one or more Markers. http://developer.martinpearman.co.uk/markers_event_layer/mousemove_ev... Markers on this map are optimised but NOT clickable and the Map mousemove event listener executes as desired. The documentation for Map events points out that the Map click event does NOT fire when a Marker is clicked on (it doesn't mention MarkerOption clickable), but doesn't mention that the Map mousemove event does not fire when the mouse is over an optimised Marker. So my question - is this a bug or the intended behavior? For my project i can set the MarkerOption clickable to false so BOTH my Map click and Map mousemove event listeners execute as desired and it will work. But i'd rather that at least with the Map mousemove event i can leave clickable set to true so that the mouse icon changes to a pointer when over a Marker. Thanks for reading my long(ish) post!

Take a look at this:

The get_tile.php script simply creates a blank PNG tile and draws the

header('Cache-Control: no-cache, must-revalidate');
$tile=imagecreatefromstring(base64_decode('iVBORw0KGgoNSUhEUgAAAQEACAYAAABccqhmB3RJTUUH2gceBB0d5vTBTAlwSFlzAAALEgAACxIB0t1+/

imagesavealpha($tile, true);

than tile refreshes will clip on each other if there is a lag spike or
the internet connection is generally slow? I guess you could always

That's right. I'm afraid I didn't make my original suggestion clear enough:
the code I linked to wasn't a way to make the remove-add sequence work
better, it was pointing to a way to avoid the remove and add entirely, by
adding a refresh method as you've done in your code here.
Also, David, I noticed one unrelated problem in the most recent code you
posted. It looked like you took my code and converted it to define its
methods using the constructor prototype instead of nesting the methods
inside the constructor. That's fine - both approaches are reasonable. But
when you converted the code to use the prototype, you made the 'tiles'
variable a global. Not good - if you ever had more than one instance of this
object it would break. Instead, if you prefer the prototype approach, the
tiles variable should be something like 'this.tiles', as shown in Martin's
version.

Have you tried simply removing your overlay map and then re-adding it?

You'll still have to watch for problems with the browser caching

should force a reload of all visible tiles.
A bogus parameter based on the current time is a good idea:
var overlayMaps = [{

That doesn't seem to be a question about the maps API, but about

to have it calculate new tiles for every request it gets. That could

[Google Maps API v3] Re: How to trigger a Tile Server to dynamically update tiles
Hi.
I nearly mentioned in my previous post that you might get a flicker as
you remove and re-add the tiles.
That's unavoidable with the code i posted i'm pretty sure of that.
To get the tiles to refresh without that flicker would require a
different approach - nowhere near as straightforward as the code i
posted.
I think you'd have to save a reference to each requested tile in your
getTile() method.
Save a reference so that you can change each tile image source at any
time.
Now to refresh your tile layer you'd iterate through all the tile
references and change the image source - with a bogus parameter this
would work.
The only problem would be knowing which tiles are still being
displayed by the map so that you don't refresh each and every tile
that has been created since the tiles were last refreshed.
Maybe you can implement a releaseTile() method in your overlay map?
http://code.google.com/apis/maps/documentation/javascript/reference.html#MapType
So getTile() would function as it does now - it would also save a
reference to each tile requested.
Your new releaseTile() method would remove references to tiles that
are no longer loaded/visible.
And every time you want to refresh the tiles, you'd get the references
to loaded/visible tiles and update each one's image source.
Martin.

[Google Maps API v3] Re: how to pass data to a marker click function
Hi uno.
Version 3 of the API has made marker click event delegation somewhat
impossible (or tricky).
The Map click event doesn't fire when the user clicks on the Map while
(also) clicking on a Marker.
So, tradionally you cannot assign a single event listener to the Map
to handle ALL Marker clicks.
I've been working on an alternative approach.
The code is not ready for public consumption yet but you can take a
look:
http://developer.martinpearman.co.uk/markers_event_layer/demo/index.htm?eventtype=click
Here a single Map click event listener detects ALL Markers that have
been clicked on.
Not just whatever Marker happens to be upper most visually (think z-
index).
There are some problems with optimised Markers, see here for details:
https://groups.google.com/group/google-maps-js-api-v3/browse_frm/thread/98cd2607d15cc805/3f6725964190a6a0?hl=en#3f6725964190a6a0
My code also works well with mouse events:
http://developer.martinpearman.co.uk/markers_event_layer/demo/index.htm
With that option a single Map mousemove event listener performs much
the same as the Map click listener.
Once Chris and the Google team decide how a Map mousemove event should
behave as regards propogation i'll work more on my code to create a
(hopefully useful) library.
Martin.

[Google Maps API v3] Re: Google Maps on android application
Hi. You have two options to display a map in an Android app i think. Create a browser based (javascript) map and use the Android WebView to render that map or use the native Android (java) MapView. A browser based map gives you access to all the current API services and easy integration with the Google Places API. You need skills in HTML5 technologies - javascript, css and html for example. A MapView requires a degree of skill in java. You would need to write methods that get data from the Places API and methods to render that data entirely in java. A browser based map on Android devices older than v3 Honeycomb will NOT support pinch to zoom and will probably take longer to load than a MapView. A MapView is quick to load and natively supports pinch to zoom on all multi-touch capable devices. Each option has it's advanatges and disadvantages though - what is your skill level? Martin.

[Google Maps API v3] Re: How to cache server side geocodes
Hi. How about first creating a MySQL table with columns 'md5', 'lat' and 'lng'. 'md5' will be a text type, 'lat' and 'lng' double type. Now create the query string that your server will send to Google, presumably something like: $geocode_query='http://maps.googleapis.com/maps/api/geocode/json? sensor=falseaddress=the_address_to_geocode'; Now create an md5 checksum of that query string using PHP's md5() function: http://php.net/manual/en/function.md5.php Next query the database for a row with that md5 value. No row in the database means you query Google and if the geocode request is successful insert the result into the database. Otherwise you can use the cached geocode result from the database. Martin.

[Google Maps API v3] Re: How to tell when an ImageMapType overlay's tiles are finished loading?
Hi.
You could keep an array of requested tiles - each time your
getTileUrl() method is called it add's a reference to the requested
tile to the array.
Then you can add an event listener to the tile image listening for the
'onload' event.
The event listener can remove the reference to the tile from the array
once it has loaded and if the array length is now zero then all
requested tiles have been loaded.

know when they are finished.
The code to create the overlay looks similar to the following:
var myOverlay = new google.maps.ImageMapType({
getTileUrl: myGetTileUrl,
tileSize: new google.maps.Size(256, 256),
isPng: true});
myMap.overlayMapTypes.push(myOverlay);
The above works just fine, and the overlay successfully loads; it just seems
that no events are emitted by the map to indicate anything about the
ImageMapType overlay's status. I would expect the map to at least emit an
idle event when the tiles are finished loading, but as far as I can tell
it does not.
How may I know when the ImageMapType overlay is finished loading?

[Google Maps API v3] Re: onclick zoom level
Look at this page:

Enter a place to search for and look at the result returned from

I'm pretty sure that not all results contain a viewport bounds (but
could be wrong!) so you'd have to test for it's presence and if
present you can use that with the Map fitBounds() method to better pan
and zoom your map.

Hello,
Is it possible to define the zoom level of a map on an javascript

What I'm trying to do with the zoom its to give individual zoom level

Different zoom level per onclick link and each onclick link will open
a new map.
Here's what I currently have:
var buceriasHTML = 'img src=images/rn-bucerias.jpg height=80

function findAddress(address, HTML) {
if (HTML === undefined) {
HTML = strong + address + /strong;

markerHTML = HTML;
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status)
{
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
addressSet = 1;
startAddress = address;
searchCenter = results[0].geometry.location;

mapPost();
}
} else {
alert(Geocode was not successful for the following reason:

}
});
}
So, each onclick link will open a new map and I'm looking to insert a
proper default zoom level per link/map. Any ideas how can I do this?
I was thinking on something like this:
lia onclick=findAddress('Bucerias, Nayarit,
MX',INSERTZOOMLEVELHERE,buceriasHTML) style=color: #009; text-
decoration: underline; cursorointerBucerias, Nayarit/a/li

map:http://www.mundoregio.com/puntosdeinteres/mapa-rivieranayarit.html
You will see below the map on the right side a 5 links and I want to include
a zoom value to those links as this are very small towns so the map will
really work better if I can give a street zoom value to each of those links.
But I'll like to give a specific value per map so I can adjust it as need
it.

Open the URL to your XML in a browser: http://www.courtsofsorts.com/phpsqlajax_genxml.php Now use the browser's View Source option and you'll see your XML - the XML also validates so you have no problem there. But the XML is being served with a Content-Type of 'text/html'. I think your problem lies there. The function downloadUrl() returns the 'request' onject to your code and your code tries to use the request object's 'responseXML' property which is 'null' or 'not defined' presumably because the XML has not been served with the correct Content-Type of 'text/xml'.

Why not make all tile requests to a PHP script?
The script can check if the requested tile exists.
If the tile exists then the script can return it to the map, otherwise
it can return a blank transparent tile.

http://www.php.net/manual/en/function.file-get-contents.php

This really hurts page load time and also looks bad for search

One other idea I have had is could I setup an .htaccess rule that
redirects to a universal empty PNG file for any tile that can’t be
found (so it doesn’t return a bad request).
I don’t want to generate empty tiles as I have over 130 custom tile
overlays for zoom levels 1 through 5. Just at zoom level 5 that would
be something like 140,000 files and my server is limited.

[Google Maps API v3] Re: map.getBounds() returning nil
Could this be a timing issue - your map is not fully initialised?
http://code.google.com/apis/maps/documentation/javascript/reference.html#Map
try this:
google.maps.event.addListenerOnce(myMap, 'idle', function(){
var bounds=myMap.getBounds();
alert(bounds.toString());
});
Add such a listener to your code after the map is created - does
getBounds() now return the correct values?

[Google Maps API v3] Re: Possibilies of eventlisteners on Markers
Instead of resizing the map to make space for the new audio/video
content you could display that content in a Custom Control:
http://code.google.com/apis/maps/documentation/javascript/controls.html#CustomControls
Use CSS margin style to position the control exactly where you want it
and CSS display style to make the custom control visible or hidden.

- resize the Map (already tried it with google.map.event.trigger(map,

- add dynamic video- and audiocontent (html5) beside the resized map.
With dynamic I mean that the content should be related to what marker

If it's not possible I'd like to know if theres some kind of
workaround. Like opening a new Window instead of resizing the map or
something like that.
I'm sorry if my question seems stupid. I started programming

You can take a look at my sourcecode right

map.style.height = 50%;
google.map.event.trigger(map, resize);
});

[Google Maps API v3] Infowindow vertical scrollbar instead of correct autosizing
Hi everyone,
this problem drives me mad and I couldn't find a satisfying answer by
googling. I have a lot of markers generated from a database. Every
marker has an onclick-listener, which opens an infowindow (there's
only one instance of this class) and displays some simple HTML
information. This works just fine. But the infowindow seems to
calculate the height of the content incorrect and so there is this
scrollbar I want to get rid of. The bar appears in FF, Chrome and IE9,
so I don't think its a browser issue.
Example: http://portal.sef-energietechnik.de/ref-test
Here is a snippet of marker generating code:
function createMarkers(xml){
var markerNodes =
xml.documentElement.getElementsByTagName(marker);
var infowindow = new google.maps.InfoWindow({maxWidth:300});
for (var i = 0; i markerNodes.length; i++) {
[...] //reading the data from xml
var marker = new google.maps.Marker({
position: latlng,
title: name,
type: type,
typeText: typeText,
infoHtml: html,
icon: markerImagesPath + markerImages[type]
});
marker.setMap(map);
google.maps.event.addListener(marker, 'click', function() {
infowindow.close();
infowindow.setContent(this.infoHtml);
infowindow.open(map,this);
});
}
}

That example is no bodge job! It'll poll the DOM til the element that you want to manipulate exists and then manipulate it - end of story. Change the poll frequenqy - maybe set a limit to the number of times that the timeout will execute before it gives up. The Google Maps API doesn't trigger many (or even any) events to let you know that it has created a DOM element 'sometime' after you asked it to. Martin.

It simply checks if there are any marker nodes returned to the map

[Google Maps API v3] Missing methods / features in v3 - Do I have to add them by my own?
Hi there, I currently want to migrate an existing application using the v2 API to the new v3 API. Mainly the application uses the GPolyline() Object to let the user draw lines and tracks and store the data of the drawed polyline into the database. In the v2 API there are many useful methods like deleteVertex(), enableEditing(), getBounds(), etc. I'm missing these methods in the new v3 API. So I search the web for more options and did not found anything about this. So my main question is: do I have to implement these missing methods by my own? For example: in our current application the user draws a line with the GPolyline() Object. If he klicks on the icon of the starting point the track were automatically closed by the event endline. This event is not available in the v3 API. So I have to check by every click if the user clicks on the starting point, therefore I have to iterate over the whole MVCArray stored in the new google.maps.Polyline() object. That seems a little bit wired and complicated to me. Can anybody tell me why these methods aren't available in the v3 API? Thanks a lot!

The cartesian projection would work directly with cartesian (x, y) coordinates with no need to convert to geographical (lat, lng) coordinates: https://groups.google.com/group/google-maps-js-api-v3/search?hl=engr...

Obviously each tile is placed accordingly on the page. My idea was to fetch this position in the getTile function and when I view a tile DIV it does show the position on the page. However, the div does not get created in getTile so it has no position yet, it returns it to another function so I cannot access the position. What does getTile return to? I think if I try to access the position from there, I can get it all working. On May 28, 7:00 pm, Jason Kaczmarsky jkaczmar...@gmail.com wrote: Alright I got something figured out. I found out how to calculate the tile at which a certain point it located based on the zoom level. I still don't understand how I can translate the tile/point position to workable coordinates. I believe if I can get a particular tile's position relative to the window position, I can then get the difference and draw a marker based on that. Don't know if it's obvious, but I'm working in JavaScript and I would like to draw a div at each point. If I can get the relative position of a tile to the window, I can absolutely position a div relative to the tile's X/Y values in the window.

All pixel coordinates are based on a particular zoom level. If all your pixel coordinates are assuming one static layer, you'll have to figure out what corresponding zoom that represents and calculate latitude and longitude based on that. Here's a Perl module with the tile math. http://www.usnaviguide.com/google-tiles.htm Hope that helps. -John Coryat http://maps.huge.info http://www.usnaviguide.com http://www.zipmaps.net -- You received this message because you are subscribed to the Google Groups Google Maps JavaScript API v3 group.

[Google Maps API v3] Disable animated zoom
Has anyone else noticed that all zoom changes are now animated and have been animated since version 3.4 (i think)? I was hoping that there would be an option that could be set to disable animated zoom changes but have found nothing. The API changelog mentions nothing about zoom changes being animated from version 3.4 or any other version: http://code.google.com/p/gmaps-api-issues/wiki/JavascriptMapsAPIv3Changelog So i have created a new feature request: http://code.google.com/p/gmaps-api-issues/issues/detail?id=3371 Anyone that would like this feature please star the request. Thanks. Martin. -- You received this message because you are subscribed to the Google Groups Google Maps JavaScript API v3 group.

[Google Maps API v3] Re: Disable animated zoom
I think the animation effect when zooming more than one level gets crude and ugly! (Although the animation effect is entirely dependant on what tiles are visible before the zoom change, so the animation effect varies from acceptable to crude). Comment #5 on this page says much the same: http://code.google.com/p/gmaps-api-issues/issues/detail?id=3033q=continuous%20zoomcolspec=ID%20Type%20Status%20Introduced%20Fixed%20Summary%20Stars%20ApiType%20Internal I think this is really a question though of personal taste - but it would be good if developers could cater for a client's personal taste. We have animated or non-animated options for changing the map center so why not have similar options for changing the map zoom? Martin.

One is complaining that markers are zoomed (which is fairly obviously a fault); the other is requesting a way to stop zoom animation. They are related -- if a zoom is not animated then markers are unlikely to be zoomed -- but it seems to me that they are not the same at all. Oops! Sorry about that. You're right, they're different issues. Can you guys please clarify *why* you don't want the map to zoom the tiles? Is it specifically the undesired effect you get from zooming in many levels? --http://twitter.com/broady -- You received this message because you are subscribed to the Google Groups Google Maps JavaScript API v3 group.
