[Google Maps API v3] Re: Geocoding API not returning lat/long for a valid complete address

[PoojaC]

Thanks for your reply.
When I investigated further on this issue, i found out that the reason is 
not that this address is new or not in geocoder db but the issue is the *postal 
code*. When i remove the postal code, it gives me the correct lat/long 
coordinates. Now, as far as i could see, this is happening with addresses 
of *India only*. One solution would be to remove this postal code but they 
would not return precise results for other addresses. Moreoever, why is 
this happening at all when geocoding api accepts the postal code in the 
input address?

[Gary Little]

Harman,

Try using the batchSizeIE parameter. It's use is covered in the
MarkerClustererPlus reference.

Rendering this many markers will still be very slow but by setting
batchSizeIE appropriately you can probably avoid the error message.

[Google Maps API v3] Issues with Markererclusterplus with ie8 12000 markers

[meenu bhatti]

Hi All,
I am using Markererclusterplus.js for rendering markers implementing
clustering.
For ie8 rendering of markers is very slow and gives error 'a script is
making the internet explorer to run slow..'

I cant change the approach as site is already in production.I tried fusion
tables,but clustering is not possible with that.Earlier there were only
5000 markers and it was fine.
Please help me .I studied that we can mark 10-15000 markers with clustering
but for me its very slow.

If any one has already implemented the same,can you please forward me the
code.It will be really helpful.

Thanks&Regards,
Harman

Sorry, but was just an example no matter the overlay type, the
question is about listeners.
Somebody else with a similar doubt?

Your original question was about 3000 "complex" polygons, not about
markers.

[Google Maps API v3] Re: Event delegation vs Event handling

[Silver]

Hi Marcelo,
Thanks a lot.
Please... check the follow example:

MyMarker = function(opts)
{
for (var key in opts)
this[key] = opts[key];
google.maps.event.addListener(this, 'click', function (ev)
{ google.maps.event.trigger(this.map, 'click_marker', ev, this); });
this.setPosition(this.position);
this.setMap(this.map);
return this;
};
MyMarker.prototype = new google.maps.Marker();
google.maps.MyMarker = MyMarker;

...
...

var opts = { zoom: 9, center: new google.maps.LatLng(-34.397,
150.644), mapTypeId: google.maps.MapTypeId.ROADMAP };
var map = new google.maps.Map(document.getElementById("map"), opts);
google.maps.event.addListener(map, 'click_marker', function(ev, poly)
{
console.log('clicked marker ' + poly.index);
});

for (var i=0; i<2000; i++) {
var marker = new google.maps.MyMarker({ title: 'Marker No. ' + 
i,
index: i });
marker.setPosition(arrayLatLng[i]);
marker.setMap(map);
}

In this case... I'm creating 2,000 markers in the loop, but I don't
need create 2,000 listeners because I'm receiving in the map the
triggered events.
Am I wrong? This way improve the memory availability?
Regards!!

I can't believe I didn't get notified about this reply...
But yeah, I include it twice, because I need two different parts: the
main library and the geometry library?
Or would the first include all?

Also, when removing one of both, it still doesnt work... :(

Any suggestions?

I don't have FF8. Looks fine in Chrome.

Try adding the overlay before adding the markers.
They go on the same mapPane, so as you're doing it now, when you do
panes.overlayImage.appendChild(this.div_);
the markers are already there.

It's an AJAX application, so it does not preserve the state unless you
preserve it in a server session or a cookie. However, some browsers
will preserve the state of checkboxes, so you could check the state of
the checkbox before loading the markers, for example:

//== Untested ===
if (document.getElementById('Checkbox1').checked) {
setMarkers(map, ElementarySchools, 'e');
}

Hello everybody,

I embedded this

Is there any way to enable on-enter-key-press search?

I would be very grateful if someone could help me.

[Google Maps API v3] Re: Event delegation vs Event handling

[Marcelo]

Polygons are not DOM objects, therefore you cannot make use of the
javascript properties event bubbling and target that are used with the
event delegation technique.
According to the documentation, the map pane that holds the polygons,
(overlayLayer), may not receive DOM events, so in terms of map
objects, the parent which could do event delegation is the map itself.
In order to do this you'd need to iterate an array of polygons and do
some point-in-polygon analysis to determine in which polygon the event
took place. This might work with click events, but I can't imagine it
performing all too well with mouseover or mouseut events, which would
have to be triggered by a mousemove event handler on the map.

In more general terms, mouseover and mouseout on as many as 3000
objects is nuts! (IMHO) :-)

[Google Maps API v3] Event delegation vs Event handling

[Silver]

Hello friends,
Some idea about events delegation instead events handling in Google
Mapas API v3??
Currently, I'm creating 3,000 complex polygons, each of them has 5
listeners (click, dblclick, mouseover, mouseout and rightclick)...
with a hight use of memory.
A better approach can be using OverlayView extending a polygon class,
setting the listeners only one time and trigger its to the map??
Some example or idea??
Thanks a lot,
Silver

[Google Maps API v3] Re: Google road layer on top of my tiles?

[Marcelo]

This should be possible, (like everything), by creating a custom tile
layer with the getTile() function from the main mapType, and with
opacity.

Here is a custom tile layer object with opacity:
http://maps.forum.nu/v3/gm_customTiles.html

... and I was trying to create what you describe when I got a BSOD, so
I am not going to try it again right now because I have work to do,
but let us know if you need more help.

[Google Maps API v3] Re: Draw regions from points at the map

[Marcelo]

Regions is a geographic concept that defines an area of the map,
therefore the only criteria that you'll be able to group the points by
is their lat/lon. No other attribute or "filter" is relevant.

You can either do clustering, as in
http://maps.forum.nu/server_side_clusterer/index2.php
http://maps.forum.nu/server_side_clusterer/index.php

or you can subdivide the country into existing political regions, such
as states or provinces, and associate each point with one of them.

If you use Polygon instead of Polyline you get additional options.

var d2r = Math.PI / 180;
//  Radians to degrees
var r2d = 180 / Math.PI;


var centerPoint = new google.maps.LatLng(lat,lng);
var PRlat = (r/3963) * r2d; // using 3963 miles as earth's
radius
var PRlng = PRlat/Math.cos(lat*d2r);
var PGpoints = [];
PGpoints.push(centerPoint);
with (Math) {
lat1 = lat + (PRlat * cos( d2r * (azimuth  - width/2 )));
lon1 = lng + (PRlng * sin( d2r * (azimuth  - width/2 )));

[Google Maps API v3] Draw regions from points at the map

[Carlos Eduardo Rührwiem]

Hello,

I'm working for a projet that needs to use about 300k points in the map. 
All of them have attributes that will be used with the input filters. I 
need to draw regions on the map that separates all of the points in regions 
that meet the specified filters. The country should have at least 400 
regions inside and this regions must cover all the country.

My team was able to group all the points using the filters and considering 
the distance between them. But I'm not sure of how can I create regions 
grouping all those points in the map leaving no space missing in the map.

Can anyone give me some suggestions?

Regards,
Carlos

[Google Maps API v3] Memory leak with setCenter()?

[Sander Sturing]

I hope this is not a repost, but I've searched everywhere and couldn't find 
a clear fix so far.

First I just initialize a very simple map (no markers etc.). I have a 
script where every couple of seconds I call the setCenter() function like 
this:

latlng = new google.maps.LatLng(56.02508 +random_number(-2, 2), 
2.39525+random_number(-2, 2));
   map.setCenter(latlng);

Is there any way to clear the memory every time this is called. It is 
called by the setInterval function and refreshing the whole page is not an 
option. I've tried re-initializing the whole map everytime instead of just 
changing position but that doesn't seem to work either.
Thanks in advance!

*BTW, the whole script is a little bit more advanced with AJAX-calls which 
places markers with infoboxes.
But after a couple of time debugging that script it seems to be stuck on 
the setCenter() part.

I saw this 
demoin
 another 
postand
 that is basically the same script as I'm describing at the top. (random 
position-changing on a single map).*

Hi All,

I new to thins group. I just want to know that what is the difference
between GGeoXml and KmlLayer methods in Google Map api. And one thing
more when i try to use this kml file 
http://www.gelib.com/wp-content/uploads/2009/world-borders_nl.kml
on map.google.com it not show me the polygon filled colors. But when i
run it with google earth or paste it on
http://kml-samples.googlecode.com/svn/trunk/interactive/index.html its
give me the polygon coloring. So what is the problem in kml file. I
want these coloring in google map.

[Google Maps API v3] A couple of things with markers titles problem and custom overlay

[K Lo]

I have been working on a map about schools in Vancouver.  For days, I
am stuck with these problems.  Would really appreciate if someone can
help.

First thing is that the titles of the markers doesn't always show in
FF (I'm using 8).  Some do some don't.  One thing I figured is that if
I move my mouse pointer outside of the maps boundary and back inside,
the one that didn't show title would then show title.  I am thinking
of making the map full screen and that problem is going to make my map
unusable for 1/3 of the browser out there.

Second thing is the custom overlay image seems to be on top of the
markers.  Is there a place I can stick a zIndex to so it'll appear
underneath?

Third thing is, if I link away from the map and then back, all markers
load regardless of the checkboxes status before I link away.  Any
suggestion on how can I control this so the right site of markers will
show when I return to the map by clicking 'back' on the browser?

Please see my code below.  Thanks in advance for helping.

[Google Maps API v3] Google road layer on top of my tiles?

[Steve D]

Possible to do this?  Lots of references to overlay's but I'd like an
underlay!  I currently have large blobs of data that are mildly transparent
on top of the google maps road layer so that the roads, lakes and other
features are visible.  It would be preferable to have my large mess of
polygon data beneath these layers.  The ability to style Google's layers
suggests that the data is flexible, but I don't know where to start.
 Ideally, my data could also sit on top of the satellite layer and below
the road layer... but I could live without that for now.  Thanks,

-Steve D

Re: [Google Maps API v3] Re: toggle only work with button not checkbox

[Johnny K Lo]

Thank you Jeff.  It was my first post.  I apologize for not familiarizing
myself with the guideline before I post.  It was a distress call...

I got it figured out and it works now.  But thank you anyway for taking the
time to answer.  Appreciate it.

Johnny

[Google Maps API v3] Re: NetworkLink kml file works in Google earth but not on Google maps (the browser map is just a bare map without any placemarks)

[Aaron E-J]

I'm begining to think that its a problem with the NetworkLink file.  I 
can't load any file (kml or aspx) using ... but I 
can load the same kml file directly in the javascript.

[Google Maps API v3] Re: NetworkLink kml file works in Google earth but not on Google maps (the browser map is just a bare map without any placemarks)

[Joseph Elfelt]

As a test you could  try taking a static version of one of your KML
files, loading it onto Google Sites (fast servers) and trying  to
display it from there.
When you get the Google Sites URL to your file, strip the  '?' and
everything  after it.

Is there any way to customize the time limit (the server is incredibly slow 
so it is very likely that this is an/the issue).
