[Google Maps API v3] Re: v3 StreetViewPanorama performances issue

[Martin™]

Hi.

I wonder if this is related to the way that the StreetViewPanorama
undocumented 'mode' property value 'webgl' is broken with v3.4 of the
API...

The StreetViewPanorama undocumented property 'mode' could be set to
'html4', 'html5' or 'webgl'.
More info on mode can be found here:

https://groups.google.com/group/google-maps-js-api-v3/search?hl=en&q=street+view+undocumented+mode&hl=en&;

I've taken the official Street View example and modified it so that
the API version and mode property can be set:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php

That's the unmodified example, try it with mode set to webgl:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=webgl

I see no Street View imagery with any browser.
(Firefox, IE8, Chrome, Safari and Opera on Win7).

v3.3 of the API and webgl work though:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=webgl&v=3.3
(Try this link with Chrome to see the better performance that the
webgl value gives)

'webgl' isn't enabled by default with Chrome and v3.3 it seems:
http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?v=3.3


'html4' and 'html5' both work with v3.4:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=html4

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=html5

One thing to note is what video hardware is installed on your computer
- is any acceleration even available?

To answer your other issue with markers and performance - have you
looked at a custom lightweight marker instead of the official marker?

Martin.

[Google Maps API v3] Re: How can i specify start position within custom panorama street view

[m...@creatiworks.ca]

I tried it but it didn't seem to help
here's my code maybe I'm doing something wrong
this is the initialize and start application functions which is where i 
assume you would put the setPosition function call
the POV is set already in panoOptions and really only sets the camera 
orientation anyway so really the only thing that will help here is 
setPosition.
I've tried setPosition(storefront) in several different locations in that 
code and it does nothing.  it actually breaks the link between the 
streetview and my custom panoramas
storefront is the name of the panorama object that i want to start at.
you can see the full javascript code tho if you view my source on the site 
and look at the js.

[code]

var carbonear_intersection = new google.maps.LatLng(47.724158, -53.24083);
var storefront = new google.maps.LatLng(yaddayadda);
var etc etc
there's alot of them

function initialize() {

  startApplication();

  // Define how far to search for an initial pano from a location, in 
meters.
  var panoSearchRadius = 30;

  // Create a StreetViewService object.
  var client = new google.maps.StreetViewService();
 
  // Compute the nearest panorama to the Google Sydney office
  // using the service and store that pano ID. Once that value
  // is determined, load the application.
  client.getPanoramaByLocation(carbonear_intersection, panoSearchRadius, 
function(result, status) {
if (status == google.maps.StreetViewStatus.OK) {
  entryPanoId = result.location.pano;
}  
  });
}

function startApplication() {
 
  // Set up the map and enable the Street View control.
  var mapOptions = {
center: carbonear_intersection,
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'), 
mapOptions);
   // Get the default StreetViewPanorama object.
  panorama = map.getStreetView();
   // Set up Street View and initially set it visible. Register the
  // custom panorama provider function. Update the StreetViewPanorama.
  var panoOptions = {
position: carbonear_intersection,
visible: true,
panoProvider:  getCustomPanorama,
pov: {heading:30, pitch:0, zoom:2},
addressControl: false,
enableCloseButton: false
  }
  panorama.setOptions(panoOptions);

  // We'll monitor the links_changed event to check if the current pano is 
either
  // a custom pano or our entry pano.
  google.maps.event.addListener(panorama, 'links_changed', 
createCustomLinks);
}

Re: [Google Maps API v3] Re: Multiple Markers, one infowindow: why?

[chinhua kong]

Hi,

Of course your infowindow are always in the same location. You should use
replace you index '2' with i.

var infowindow2 = new google.maps.InfoWindow(
{
content: tooltip2,
//position:
getPosition(loadCoordinates[2]['lat'], loadCoordinates[2]['lng'])
//position: loadedMarker.getPosition()
position: new
google.maps.LatLng(loadCoordinates[i]['lat'], loadCoordinates[i]['lng'])
});

You are trying to access the "map" variable which is local to the
init() function in the global scope.

(this is a FAQ) for details on scope see this page of Mike
Williams' (v2) tutorial:
Javascript Concepts -Part 1 Scope
http://econym.org.uk/gmap/scope.htm

1. outside all functions declare a global "map" variable.
var map = null;
2. initialize it in the init function:
function init() {
...
map = new google.maps.Map(mapDiv, {
...
}

[Google Maps API v3] v3 infowindow and animating through markers

[nny]

hello,

I have a few quick questions. This is my uni project: 
http://playingintraffic.co/respondent-7/
i would like the map to animate along the path of the markers in order 
rather than skip to the last marker when the play text button is clicked.

also the graphics around the infowindow are broken and I dont  understand 
why.

any tips in the right direction would be apperciated.

peace,
dan.

Yeah, not sure how to get round it. Just trying to make the circle overlay
work from onclick rather than load.

If can do that then sure can try attach to current active pin.

Re: [Google Maps API v3] Marker Position - google.maps.LatLng

[Barry Hunter]

If you are attempting to use the Geocoding API, to 'convert' these, then -
dont.

It instead runs a referese geocode on the coordinates- and may end up giving
a far away place.

The javascript to do the conversion yourself, isnt that difficult.

Example:
http://homepage.mac.com/bruno_andrighetto/JavaScript/DegreesMinutesSeconds.html

http://www.google.com/search?&q=degrees+minutes+seconds+to+decimal+degrees+javascript

[Christopher Watson]

tried to attach to pins when clicked

http://creativemaps.vism.ag/circle3.htm

its probably way off but cant quite make the radius overlay display from an 
onclick. is it way off?

well, my thinking was when i can get it to be used as an onlick i can try to 
attach the onlick to pins in here for example 
http://creativemaps.vism.ag/la.htm

ona further note, tried to add 

   function RadiusWidget() {
 var circle = new google.maps.Circle({
   strokeWeight: 0   
   fillcolor: #ff66ff
 });

but didnt work. 

can anyone help with the seperate javascript link to a function to display 
the circle overlay? or the colour styling of the circle overlay?

prob solved. 

i went searchign and found another http://creativemaps.vism.ag/circle2.htm

documentation here: http://code.google.com/apis/maps/articles/mvcfun.html

just updating as i go... going to try add the colour customing from the 
documentation and make a second one for longer distance. then see how to 
make them attach to pins when clicked.

hmm... keep fiddling and hopefully getting them to work. 

still curious about the second projected overlay mind you.

[Google Maps API v3] Re: Trigger click event on KMLFeature

[jacek.francuz]

Thank you for the confirmation. My KML's are very complex. I have
tried to use GeoXML3 but with no luck - it use to take ages to
generate all the shapes and browsers abandon the script's execution. I
think I must leave this idea.

Thanks for your help

With KmlLayer that is correct.

How complex is your KML?  Have you looked at geoxml3?

[Google Maps API v3] Re: Trigger click event on KMLFeature

[jacek.francuz]

Hi,

thanks for the prompt reply. Actually I wanted to use 'click' event
because KMLLayer has no 'mouseover' event defined for it. My idea was
to trigger programmatically 'click' event when mouse is  over the map
and check what KMLFeature the cursor is on.

I think it is impossible though :S

[Christopher Watson]

http://gmaps-samples-v3.googlecode.com/svn/trunk/circle-overlay/circle-overlay.html

ok, went lookingf further saw this that looks really simple. will have ago 
at attaching to a onclick function. prob b back when stuck.

the projected overlay, i want to have a second layer to load on top of the 
projected overlay already there and have its own toggle button, is this 
possible?

so layers in projected overlay, and one to load on top of the other, both 
controlled by buttons to hide/view. 

hopefully bit clearer. i should review my writing more. sorry for confusion.

Have you looked at FusionTables?  You can fake the same action by
querying the FusionTable and opening the same infowindow that would be
opened on a click.  You can even import KML.

Re: [Google Maps API v3] Marker Position - google.maps.LatLng

[chinhua kong]

Your Lat, Lng are wrong for the not working set. The right Lat, Lng should
be these
Sevilla: 37.387697, -6.001813
Lisbon: 38.725735, -9.150210
Casablanca: 33.5556, -7.631940

What Geocoding tools are you using? It seem like all the negative value is
been absoluted. Here  a link you can use
to view your lat, lng position on the map.

[Google Maps API v3] Trigger click event on KMLFeature

[jacek.francuz]

Hello,

is it possible to programmatically trigger click event for KMLFeature?
I need KMLMouseEvent to be passed to KMLLayer handler. If not, then
maybe it is possible to populate such a object or get reference to
KMLFeature objects?

[Google Maps API v3] Can I have a toggle onclick polyline 'filled' arc to surround a marker? Can I adapt Projected Overlay to have 2 toggles of layers?

[Christopher Watson]

http://gmaps-samples-v3.googlecode.com/svn/trunk/circle-overlay/circle-overlay.html

i saw this, can it just load when onclick event happens with any pin?

how could i work out the radius? does anyone know an estimate of walking 
distances for 5 mins average?

I want it to work as one coloured radius to depict 5mins walking distance 
from a location, and then a second toggle button to hide/view a second to 
depict 10 mins walking distance.

can i adjust the colours too and opacity level etc of the polyline arc?


The second projected overlay is a bus routes map/image that i'd like to be 
able hide/view?

i'd do actual directions for the routes but not sure how exact to the routes 
they take would work. so a second projected overlay straight from the bus 
route map will work.

hope you can help.

Sure.  The documentation explains all the parameters of polygons.

Convert it to meters?  Or change the function to use whatever your
units of choice are.

[Google Maps API v3] how to add listener to get bounds after mouse action

I'm trying to get new bounds after mouse action (zoom in/out, pan).
One post says that we can use idle. However the following code doesn't
work except the first time when the page is loaded. Could any one
kindly tell me how to add listener to get bounds after mouse action.

google.maps.event.addListenerOnce(map, 'idle', function() {
var mBound = this.getBounds();  });

Thanks a lot

[Google Maps API v3] Marker Position - google.maps.LatLng

[Loonis]

Dear Experts,

LatLng is driving me crazy... My base data is in degrees / minutes /
seconds format and to create my markers on the google map, I convert
this data into decimal values. This works perfect for most of my
markers, but some markers being positioned in the middle of nowhere.
Here some examples:

Working perfect:
Cologne: 50°52'2'',7°8'37'' => 50.8672,7.1436
Paris: 49°0'46'',2°33'0''  => 49.0128,2.5500
Bejing: 40°5'44'',116°35'18'' => 40.0956,116.5883

Not working:
Sevilla: 37°25'5'',5°53'35'' => 37.4181,5.8931
Lisbon: 38°46'53'',9°8'9'' => 38.7814,9.1358
Casablanca: 33°33'20'',7°39'40'' => 33.5556,7.6611

Really can't figure out what the problem is, anyone got any idea?
Thx for your help in advance!

[Google Maps API v3] v3 StreetViewPanorama performances issue

[Remi Grumeau]

Hi group!

I've been thru a couple of v3 API StreetViewPanorama tests lately and i've 
noticed a couple of issues with it:
- Only Chrome on PC renders a 3D effect. On all others, it's just a 2D image 
sliding ... even Chrome OSX ! Is that supposed to change soon?
- Adding a custom line + custom panorama is quick and easy... but with 
actual API, it's just a PIA to put a link to it on different locations (when 
on cross streets for example, or plazza).
- To avoid previous issue, i'm using markers with setPano(). But markers on 
a StreetViewPanorama has a HUGE performance issue compare to the same with 
lines only : (

Are we gonna have a StreetView stunning 3D look'n'feel in custom panorama 
soon? 
Are you aware of this marker performance issue?

Cheers

Just comment out (or remove!) the


  panoramioLayer.setMap(map);


line. That way the layer is never added to the map in the first place.
(it will still be added as required by the click listener.

[Google Maps API v3] Tile Loading Performance

[Jonas]

I'm working on a little project that uses the Google Maps API v3 and I
have a custom tile set that I'm using.  Right now I'm working on
improving performance and it would help to get a better idea of how
Google Maps does the tile loading.  Does the API abort tile loading if
the user has zoomed or panned away from the area?  My tiles take a bit
to load so I'm hoping the API aborts tiles that are no longer needed.

If this is the case, out of curiosity how does the API do this?  Does
it implement a queue of tile requests and as tiles load it pulls more
tile requests from the queue?  Or does it put all the requested tiles
right in the DOM at the start and have some sort of method to abort
them if needed?  Thanks for your help!

Where does infowindow2 get defined?  I'm suprised you get one at all,
but then I can't see the whole context of your code snippet.

You know the routine by now, a link to your problem map would give

[Google Maps API v3] Multiple Markers, one infowindow: why?

[thebit]

Hello,
I wrote the following JS function which load all saved Markers and
show them onto a map.
All this works, but if I click over a marker, the infowindows is even
open in others coordinates.

Please, look this code:
*
function getSavedMarkers()

{

$.post("LoadCoordinate.php", function(data)

{

var loadCoordinates = data;



var i=0;

for(i=0; i'+
'';
var infowindow = new google.maps.InfoWindow(
{
content: tooltip2,
//position: getPosition(loadCoordinates[2]['lat'],
loadCoordinates[2]['lng'])
//position: loadedMarker.getPosition()
position: new 
google.maps.LatLng(loadCoordinates[2]['lat'],
loadCoordinates[2]['lng'])
});

google.maps.event.addListener(loadedMarker, 'click', function()
{
infowindow2.open(map,loadedMarker);
//infowindow2.setPosition(loadedMarker.getPosition());
});


}

}, "json");
**

Why does not correctly set the position?
I tried in many way (look the commented lines) but the infowindow was
opened in the coordinates of the last marker loaded.

I hope you can help me.
Thankyou in advance.

Re: [Google Maps API v3] Re: Display panoramio layer inside infowindow

Thank Chris.

1 - Re Panoramio in info window. This was because I didn't want a map 
covered in photos, but when a marker is clicked a small map appears in the 
info window with all the photos for that location;

However I agree with you and simply having a toggle button is probably a 
better user experience. Thanks.


2 - The toggle button works well. Can I make the default as "off", so the 
user has to click the button to view the images?

using divs: it shows with the right size (the same size of the google maps 
default controls) when I see the map using a computer ( 
http://www.mastercomunicazionestorica.it/geo/controllip.html ) but when I 
access the same map through a mobile device, Google maps default controls 
become bigger while my custom control remains of the same size (smaller in 
respect to google default controls: 
http://www.mastercomunicazionestorica.it/geo/controls.jpg ): how can I avoid 
this problem, making my custom control of the same size than the default 
controls when accessing the map through a mobile device? Thanks for helping 
me,best,

Giac

Re: [Google Maps API v3] Re: Markers and zIndex

(originally posted to the wrong thread :)

Unfortunately it is not feasible to put draggable markers below canvas
markers.

So, unless you want all your draggable markers above canvas markers, it's
necessary to specify optimized: false when creating your non-draggable
markers.

Hope this helps,
Chris

Yes, but why?! I can't possibly imagine that this would be a good user
experience.
