I'm building an application where user-submitted posts are placed via their location as markers on a Google Map. The users are currently able to view the markers/posts on a map in relation to their current location.
What I'm aiming to do is allow the user to change the location of the map so that users can see the markers/posts in relation to another address, specifically via a form that allows them to enter an address and change the location of the map.
I found a YouTube video illustrating a pretty close approximation of what I'm aiming to do, but it unfortunately provides no code or instructions (http://www.youtube.com/watch?v=4uyIawlsvzU).
Is there a way to efficiently wrap an existing Google Map and the existing markers into a form such as this? I've searched for a solution but can't seem to find the proper way to achieve this. Many thanks for any feedback.
You need to search for LatLng by user specified address and to display it. I see not problems at all :)
Study Google Geocoding API for this (seems best solution for your case) and this example

I have created a map using the Google Maps API v3.
I have created a Fusion Table with a hundred locations (markers) or so and have that successfully pulling into my map.
Now I need to add a search box to this page that will allow the user to enter their zip code and have the map zoom in to that area, then only seeing the locations in that zip code or the nearest locations to that zip code. I would also like the location data to pull into a sidebar as seen with the now deprecated Local Search API.
I have read most (if not all) of the posts that seemed to be about this, but to no luck. I feel like this shouldn't be that difficult really, I mean Google does search primarily right? Yet adding a search bar to my custom map is such a difficult task.
Any help would be appreciated, I have a deadline of tomorrow. Thanks everyone, I love it here.

You will need to geocode the zip code and use the results to center the map, then show the markers that fit the bounds of the map if they are not already shown.
See http://code.google.com/apis/maps/documentation/javascript/geocoding.html
There is an example with a search box.
I have a Google map I have created to highlight the location of several support groups by adding my own pins using my maps and embedding this into my website.
Is there a Google widget of any description to allows people to search my custom map and find their nearest support group (or nearest pin).
I have read through the Google maps stuff but cant seem to find anything that meets my requirements.
Any help appreciated.
The map has no clue about which markers or overlays you have put on it. Therefore there are no way you can do what you want using Google Maps directly. You can however do something else.
When you create your markers/overlays and place them on the map you can add them to an array. When you users then enters a location you can search through that array to find the markers that are closest to the location the user has entered. Google Maps API has a method for getting the distance between two latlngs, but you can also use an ordinary Haversine formula for calculating it.
Once you have found the closest markers it is not hard making sure they are the only ones that are shown on the map.
I am working on a location-based service platform, that will be coordinate based. In ideal situations, I can have the GPS grab the coordinates. However, I would like to have a fallback where I would have an autocompleting text field in which a user can input the address/name of the place. The autocomplete dialog would try to make a smart guess what the place is, just like how it would work in Google Maps when you try to search for a location.
Is there an API for this?
You can use the Google Places API.
There is also a handy jQuery plugin called geo-autocomplete that can help you with this.
See also the Google example, and documentation.
I have a map of several counties I need to turn into a county select menu (i.e clicking Leicestershire will select Leicestershire.
I am using a php built system that this map will need to return the appropriate value to. I am thinking this will be a get in the url, checked for valid values in the backend.
How would you approach this? A html co-ordinate map? Some sort of Javascript? Flash?
I am aware all those solutions have one drawback or another. Does anyone know a better way of doing this? Or an existing opensource project?
Just an idea, if I read your problem correctly: I would personally use the Google Maps API for this. Plot each county onto your custom Google Map, then when you click each marker an info window could appear with "Select this County". Click the link and pass a value through the URL to your PHP script.
Used a html map system. Dreamweaver made it easy (first time I've used the design screen seriously)
Well i want to upgrade contact page with dynamic map showing location and give oportunity to calculate route for comapny headquatters. Id it necessery for such simple task use Google api? i mean here generating akey etc? Fo i have any other alternatives to google maps?
There's really no reason to mess with the API at all unless you need to customize the appearance or behavior of gmaps. Why not just use an iframe with a url of:
http://maps.google.com/?q=[you-url-encoded-address-here]
or better yet, set up a textbox and a 'get directions' button to redirect that frame to:
http://maps.google.com/maps?saddr=[their-address]&daddr=[your-address]
edit: this works well in modal dialog if you don't want the google logo sticking out like a sore thumb in your pageflow
You could probably embed directly with a specific URL that will configure it to have the destination you want.
By the way, well written answers are much more likely to receive useful responses here.
You could consider http://www.openlayers.org/ as an alternative to google maps.
In fact open layers can be used to add a Google map, or an OpenStreetMap map or a Bing map, etc.
