I need to implement directions using Google maps inside my GWT web application.
Currently I'm using maps API v2 library.
I have several issues I have not been able to solve yet:
Include Get Directions panel (similar to the Google maps one)
Get list of streets names from the request.
PS How to implement mouse wheel zoom control?
Here is the answer for your mouse wheel zoom question
Implement HasMouleWheelHandlers and its the API's like getX(), getY(), getScreenX(), getScreenY() and do your zoom operations
I found out how to easily implement zoom functionality:
final MapWidget map = new MapWidget(startLatLng, 12);
map.setSize("100%", "100%");
MapUIOptions options = map.getDefaultUI();
options.setScrollwheel(true);
map.setUI(options);
For more info check out maps demo. You can checkout project code and test it in eclipse!
I'm still searching for solution to other problems.

i am placing some locations on google map. i need to set text next to marker on the map. is there a way to do it ? because i can not see any tools or option provided by google maps to do.
its not an application i am developing or coding. i am just saving locations on google map site.
Thanks
Look at the InfoBox from the utility libraries. There is an example in the documentation.
I am developing JavaME LWUIT application which needs to display some data on map.
And I'd like to use Google Maps for this.
I thought about the requirements to the maps and their user interface. They are
listed below:
Pannable map. It should be possible to scroll the map using the touch interface or navigation arrow buttions which are displayed on the map.
Zoomable map. At the best, there should be appropriate +/- buttons displayed on the map.
Search location by address and move to it (menu command).
Remember the last visited location.
Marker for the current location.
Markers with customable icon and text which is displayed when select the marker (click on it or select somehow).
I spent some time searching for appropriate Map Library for JavaME/LWUIT.
I expected to find a free library and map service (ha-ha).
See my results below:
MIDMaps library. URL: http://www.jappit.com/blog/midmaps-google-maps-java-me-library/
That library uses the Google Static Map Service. Not bad... but it needs a lot further improvements...
I found the follwoing issues with that library:
Markers: impossible to customize marker's icon and text. Displaying the marker's text on click/selection is not supported.
Map Panning: no UI controls for this (arrow buttons). Doing panning with menu commands is not a user-friendly.
Map Zooming: no UI controls for this (+/- buttons). Not so important...
License: not permitted to use in a mobile app if not a Google Premier User. Not a problem...
Nokia Maps API for JavaME. URL: http://www.developer.nokia.com/Develop/Maps/Maps_API_for_Java_ME/
Did not try. But looks like that lib fulfills all my requirements.
I am not sure about the following things:
Quality of the maps.
How much does it cost? I mean the cost of using the map service.
Nutiteq lib which uses OpenStreetMap service. URL: http://www.nutiteq.com/map-api
Not free the lib, but the map service.
Guidebee Map API. URL: http://www.guidebee.biz/
It's not free.
Now it's a time for me to ask questions. What should I do? Are there any advices?
Maybe I missed some possibilities or lib/services?
Thank you for your help!
See the Makeover demo in SVN (I updated it to use Google maps instead of Yahoo maps API which was killed off). The GoogleService API should be available in the SVN history it was (deleted because of licensing nonsense) within the IO services directory and it includes local search etc.
Terrence has a a demo that includes allot of interesting features including a browseable map.
You can also look at Waze although I haven't checked it myself, I saw people using open street map and AFAIK there is an open source mapping application based on that (although the license might not be appropriate for you but it might still be useful as a learning aid).
After some additional investigations I decided to use Nokia Maps. And now I have a working application which displays interactive map with my data markers on it and also my current location.
I chose Nokia Maps API because it provided real dynamic maps (panning, zooming, tiling) and fulfilled all my requirements, except "Remember the last visited location" (can be implemented on my own).
I met the following problems:
Using the maps from LWUIT, not from an ordinary MIDP application. I used the approach shown here Nutiteq SDK with LWUIT and also implemented my own MapWidget class for LWUIT.
Displaying additional info on marker click. There is no support for this in the lib. I had to implement it on my own. Details are here JavaME Nokia Maps API: how to display additional info on marker click
Additional info related to the choosing proper map library can be found here Discussion on Nokia Forum
How to get the coordinates of an Google Map using mouse click in the c# and .net?
I don't fully understand your question.
I found a nice article about getting coordinates from Google Maps using C#:
http://jasonjano.wordpress.com/2010/02/10/address-geocoding/
Maybe it will be useful for you.
Please take a look at this implementation of http://map.embed.ly/ [google maps][1] . Would like to know how it can be achieved ? I have seen only satellite, hybrid implementation this seems new to me

It looks like a well done custom overlay on top of Google Maps API (v3).
The GMAP API website has an example that shows the code as well as the output. Good luck!
What you're looking at doing is implementing the Google Maps API. It provides methods for placing custom overlays and data sets into a Google Maps interface:

I'm absolute newbie as for Google Map / Yahoo Map. I would like to know if it is technically possible to ask to show any city in any country DYNAMICALLY (I mean by passing parameters) and then to show some pictures OVER the map near the city ?
Thanks.
There's a multitude of ways you could accomplish this, some prettier than others.
You could use GInfoWindow to display a popup window with pictures in it at any location.
You could use one of the handy libraries offered here http://code.google.com/p/gmaps-utility-library-dev/ to assist you in displaying those images.
What I would recommend, however, is using http://econym.org.uk/gmap/ewindows.htm to create a window that is similar to GInfoWindow but that is styled by you. Just style the window so that it appears to simply be an overlaid picture.
You could choose to fool around with z-index's and manual positioning with a JavaScript library like jQuery.
Also, to answer the beginning of your question yes you can refocus the map anywhere using GMap's .setCenter() method. Documentation of setCenter(), GInfoWindow and much more available at http://code.google.com/apis/maps/documentation/reference.html
I just started learning this myself.
Here is a good link to get started:
http://code.google.com/apis/maps/
On your second question,
show some pictures OVER the map near
the city?
I like #andykram's response above, but I've implemented this previously using the Panoramio layer available for the Maps API. It can get a bit crowded but its an interface people are used to and because it is so simple to include it in a map, it just be the solution for you this time.
Just add the following to your map initialisation function.
var myLayer = new GLayer("com.panoramio.all");
map.addOverlay(myLayer);
As far as dynamically showing any city in the world in a Google Map, the solution is easily implemented - you need to geocode the name of the city. This can be done by triggering a function on an event like onclick.
function showAddress(address) {
if (geocoder) {
geocoder.getLatLng(
address,
function(point) {
if (point) {
map.setCenter(point, 13);
var marker = new GMarker(point);
map.addOverlay(marker);
marker.openInfoWindowHtml(address);
}
}
);
}
}
If you hit a hurdle, try this first - http://econym.org.uk/gmap/ - possibly the best resource for the GMaps API on the web.
GeoExt is a nice framework if you work with maps in general. You can access other kinds of maps too (OSM, GeoServer).
