List of junctions - google-maps

I would like to get a list of junctions' coordinates in a radius around a given coordinate. I figured there should be a way to extract the coordinates of wherever two roads meet, however I can't find it. Please advise!

That functionality is not available in the Google Maps API v3.

Google Maps: Draw polygon surrounding random locations

I have a set of random locations. The location set will keep changing. I would like to draw a polygon surrounding these locations.
Can this be done in Google Maps and how? The map will be displayed on a website only, no mobile api required.
It's called a convex hull. Here:

I would cite the code but it belongs to #geocodezip who is the authority on google maps and runs an excellent site of examples. I suggest you check it out.

How can I see the nearby places between two locations in Google Maps?

How can I see the nearby places between two location.
For example:
From:İstanbul
To:Ankara
I want to see cafes on this route.

I can suggest having a look at RouteBoxer library. This library allows to generate a set of LatLngBounds objects that are guaranteed to contain every point within a given route. After that you can use places search with a set of LatLngBounds to find cafes within given bounds.

For android after select for example driving, at top you can change "Your Location" to anywhere else.
or you can use "Measure distance" to calculate direct distance between places.

Google map API for finding whether a location inside/outside of circular/rectangular area?

I have to find out whether a given lat/long value is with in a circle/rectangular area whose centre is some lat/long with some fixed radius.
is there any google maps API available for that ?
You can look at the documentation - containsLocation
Here is the link:

Search a google map I have created and embedded into my website

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.

google maps ruler

does someone know how can i add the distance ruler to my api map, or any other quick way to se the distance bwtween 2 direct points?
You could try some of the js extensions available online. For example:
http://code.google.com/p/earth-api-utility-library/source/browse/trunk/extensions/examples/ruler.html?r=41
I'm not familiar with the Google Maps API, but given latitude and longitude of any two points you can use a great circle calculation to determine the distance between them.
