Google Earth Integration/ Maps V3 Flyto Onclick - google-maps-api-3

Using the new "hackish" integration for Google Earth ( http://code.google.com/p/google-maps-utility-library-v3/ ) I have gotten this example working and worked plenty with the Google Earth plugin and V2 of Maps. I was curious as to how to access the flyto and lookat functions onclick.
Previously you could call a function like this within an anchor link and it will flyto when clicked
function viewSouth() {
var lookAt = ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND);
// Set the position values
lookAt.setLatitude(28.54626988796781);
lookAt.setLongitude(-81.37704984953177);
lookAt.setRange(1070.448301908147); //default is 0.0
lookAt.setTilt(67.84202025905072);
lookAt.setHeading(-179.9640072336487);
ge.getView().setAbstractView(lookAt);
}
This it seems doesnt work with the new integration method. Could I possibly get some quick instruction as to how to access this function withing the Maps V3/Google Earth Integration
Thanks in advance!

I was able to use the googleEarth variable which was set to equal GoogleEarth(map) and then it worked! thanks

Google map how to display a dragable marker based on coordinates and return new coordinates

I have to write a script for Google Maps V3 which will do the following:
Place a marker on a map based on a set of coordinates and possbibly change the address after the page has been loaded
Allow the user the drag the mark to replace it elsewhere
Collect the new coordinates once the marker has been moved.
The first part is basic enough and should be fine, changing the address after the page is loaded should only be a matter of calling back the same function?
I am not sure where to start on the draggable marker and collecting hew coordinates.
Would anyone know of scripts / API's or where in the doc should I start?
Have you checked the Google Maps Javascript API V3 Reference to see whether the google.maps.Marker class has :
a draggable option
an dragend event
a getPosition method
Hint: The answer might just be "yes" to all three, and you don't need much else to solve your problem.

Google Maps API v3 Google Earth API integration - load Earth view on load

I'm using the google-maps-utility-library-v3 to incorporate a Google Earth API view to a Google Maps API v3 implementation. Those Google Maps API v3 / Earth API utilities have been written by user jlivni as far as I can tell, the availability of which code has helped me greatly thus far.
(very rough working prototype of my implementation is here)
The problem I have is that I want to default (on page load) to the Google Earth view, rather than (as in the prototype above) one of the Maps API v3 standard views.
I have looked at lines 81, 131 and 133 of the (uncompiled?) googleearth.js at the above link (under src) and tried the following when setting the Maps API options within my JourneyImmersionInitialiseMapLoadGPXAnimate.js ...
var myOptions = {
zoom: 18,
center: arr_lat_lon[currentTrk][currentTrkseg][0],
scaleControl: true,
tilt: 45,
mapTypeId: earthMapType,
overviewMapControl: true,
overviewMapControlOptions: {
opened: true
}
};
map = new google.maps.Map(document.getElementById("map"), myOptions);
... but get ...
ReferenceError: earthMapType is not defined
Additionally I've tried ...
mapTypeId: GoogleEarth.earthMapType,
... which results in a grey map canvas with no map type options on the top right. Once I've selected the Earth view from the page I can then change between the standard Earth API map types at the console in Firebug using ...
earth.getInstance().getOptions().setMapType(earth.getInstance().MAP_TYPE_EARTH)
... or ...
earth.getInstance().getOptions().setMapType(earth.getInstance().MAP_TYPE_SKY)
... but again, use of earthMapType or GoogleEarth.earthMapType in place of the last element results in an error at the Firebug console, this time ...
Error: Error calling method on NPObject!
Any help would be greatly appreciated.
Thanks in advance
(as I'm a newbie I can't provide more than two links in this post but wanted to add that I have looked at stackoverflow.com/questions/3039250/google-earth-integrated-with-google-maps-api-v3)
This library doesn't have a public method to switch programmatically, and if you try to do it before all the setup is in place, it will fail. Ideally there would be a callback after instantiating your GoogleEarth object, but lacking that you can hack around the issue by using the private showEarth_() method on the uncompiled JS.
Noting you have to wait an arbitrary amount of time before the plugin is ready, something like this should generally do the trick:
googleEarth = new GoogleEarth(map);
setTimeout('googleEarth.showEarth_();',1000);
This is all pretty hackish, so please file a feature request on the issue tracker to add in a supported method for switching to the Earth type programmatically.

google map api v3 Weather information

How do we add the weather overlay option to a Google map, just like on Google my maps?
I've searched for it, but i can't find the answer.
Do i have to call a weather web service?
You can display the WeatherLayerdev-guide on your map by taking two steps:
First, load the WeatherLayer library by adding the libraries parameter to the URL you use to load the map:
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?libraries=weather&sensor=false">
</script>
Then, you must create an instance of the google.maps.weather.WeatherLayerapi-doc class, passing any options in a WeatherLayerOptionsapi-doc object, and attach the WeatherLayer to the map:
var weatherLayer = new google.maps.weather.WeatherLayer({
temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT
});
weatherLayer.setMap(map);
In addition to the WeatherLayer, there is also a separate google.maps.weather.CloudLayerapi-doc class that you may create in a similar way:
var cloudLayer = new google.maps.weather.CloudLayer();
cloudLayer.setMap(map);
There is no separate library that you must load to use the CloudLayer; adding the libraries=weather parameter to the URL that loads the map makes both the WeatherLayer and the CloudLayer available on your map. There as a Google Maps JavaScript API v3 Example: Weather Layer, that shows the usage of both layers.
I have got same trouble when I tried to use Google map apiv3 with weather layer. But luckily, I found this site http://code.google.com/p/gmaps-samples-v3/ that provides all Google map api v3 samples and they are worked. Hope this help.

Google Maps API V3 prevent from adding "Listing by" when placing markers after a places search

I run a search using google.maps.places.PlacesService(map) and then I place markers on the map which is fine. I do this every time the "dragend" event occurs.
But then, every time, it added on the right side of the map "Listing by yellowpages". So if I scroll 3 times, I get 3 "Listing by yellowpages". How do I remove that?
I had a similar problem using the Google Maps API. Turns out it was caused by the fact I was creating a new PlacesService object every time, and when I switched to having just the single PlacesService object, this problem went away.
So make sure you only have once PlacesService object created and linked to the map.
Show last listing-by only
lib jquery
service = new google.maps.places.PlacesService(map);
service.textSearch(request, function(request, status){
if(status==google.maps.places.PlacesServiceStatus.OK){
$('.listing-by-map').hide();
$('#map div').last().addClass('listing-by-map');
//...
}
});

Yahoo Maps API - Same code ok in Firefox, not IE7

I've implemented a simple yahoo mapping example using JQUERY.
My problem is i'm developing using my localhost, my intended target platform is to be within an Intranet environment. My thinking is that my localhost will to some extent mimic this.
I have an update, made some progress. See the code snippet below, all ok in Firefox but in IE (my target browser) it fails on the line:
var currentGeoPoint = new YGeoPoint($('#txtLatitude').val(), $('#txtLongitude').val());
What I cannot understand is why will IE allow the MAP API Code to run and manipulate the MAP object and fail on this one line.
Could this all be to do with Tools/Intranet Options/Security and trusted sites etc? My URL locally is "http://localhost:4724/LMS/Site.mvc/Details/77" if thats any help.
$(document).ready(function() {
jQuery("textarea[class*=expand]").TextAreaExpander(); // initialize all expanding textareas, new code, john s 10/08/2010
var geoPoint;
// Create a map object
var map = new YMap(document.getElementById('map'));
// Add map type control
map.addTypeControl();
// Set map type to either of: YAHOO_MAP_SAT, YAHOO_MAP_HYB, YAHOO_MAP_REG
map.setMapType(YAHOO_MAP_REG);
// Display the map centered on a geocoded location
map.drawZoomAndCenter("United Kingdom", 12);
// Add map type control
map.addTypeControl();
// Add map zoom (long) control
map.addZoomLong();
// Add the Pan Control
map.addPanControl();
// Set map type to either of: YAHOO_MAP_SAT, YAHOO_MAP_HYB, YAHOO_MAP_REG
map.setMapType(YAHOO_MAP_REG);
// Display the map centered on a geocoded location
map.drawZoomAndCenter("United Kingdom", 12);
var currentGeoPoint = new YGeoPoint($('#txtLatitude').val(), $('#txtLongitude').val()); // FAILS IN IE ON THIS LINE!! Unspecified Error popup dialogue box
map.addMarker(currentGeoPoint);
});

Have this working now, reverted back to original javascript, i'd hand rolled my own code and although neater was not working in IE. Glad to be out of the woods, cheers, J
