[Google Maps API v3] How to find the lat lng from a geocoded address?

[Daniel Montenegro]

Hi there!

I've posted this question in stackoverflow:

http://stackoverflow.com/questions/11944681/how-to-find-the-lat-lng-from-a-geocoded-address

Basically, I'm trying to figure out how to put the lat lng values in those 
two forms (Lat Lng) right under the map. I've already seen some examples 
showing how to get latlng from an address but I can't make it yet...

Thanks in advance,

Daniel

Re: [Google Maps API v3] Links being rendered in arbitrary directions in StreetView app

You probably need to adjust the originHeading on your custom panoramas.

[Google Maps API v3] Modify Marker Label CSS Property

[Buster]

Hi,
If possible, I would like to dynamically modify the CSS width property
to reflect the width of the labelText string.
For example, the CSS set width property is 40px.  The text string
property is 100px.  Change width = 100px


   .labels {
 color: red;
 background-color: white;
 font-family: "Lucida Grande", "Arial", sans-serif;
 font-size: 10px;
 font-weight: bold;
 text-align: center;
 width: 40px;
 border: 2px solid black;
 white-space: nowrap;
   }
 

function createLabeledMarker(lat, lon, labelText, infoText,
iconURI) {
var html = "" + infoText +
"";
var thisMarker = new MarkerWithLabel({
map: map,
position: new google.maps.LatLng(lat, lon),
title: '',//mouseover popup label
icon: iconURI,
draggable: false,
raiseOnDrag: false,
labelContent: labelText,
labelVisible: true,
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: { opacity: 1.00 }
});

changeWidth(labelText.length);

bindInfoWindow(thisMarker, map, infoWindow, html);
gmarkers_list.push(thisMarker);
}


function changeWidth(newWidth) {
var elem = document.getElementById("labels");
elem.width = newWidth;
}

I've tried this, but no joy.

appreciate any assistance.

thanks.

[Google Maps API v3] Links being rendered in arbitrary directions in StreetView app

[Jason]

How does StreetView determine which direction is north?

I have a series of panoramas with links between them.  These panoramas have 
GPS coordinates associated with them and I use them to calculate the 
compass bearings between two links.

However, it seems that the links themselves are being rendered in arbitrary 
directions regardless of the heading value.

In my panorama options, I've set the default heading to 0.  If this is 
combined with a panorama heading of 0, the view is rendered from the center 
of the panorama.  Unfortunately, as my link bearings are based off GPS 
coordinates, if there is no constant north value, the links get rendered 
all over the place.

How would I solve this?

The API calls your "draw" method automatically.  It might be happening
too frequently.  You could use an "idle" event to update your
overlays.  You could perform a test in your "draw" method to skip
updates if the collection of map tiles has not changed since the last
update.  Trying to maintain overlay consistency during dragging has no
real benefit.  Once the map has settled, the overlays ought to be
updated.  Also, if you can combine your overlays into a single CANVAS
element with a single "draw" method, it will be much more efficient
than multiple CANVAS elements with multiple "draw" methods.
