I wonder if anybody knows whether it is permitted to use a the distance matrix service in the code behind without displaying the google map on that specific web page. The google map will be displayed on another page on the same website, but does using the service elsewhere without the map violate the google terms and conditions?
According to the Google Maps API Web Services Documentation:
Use of the Distance Matrix API must relate to the display of information on a Google Map; for example, to determine origin-destination pairs that fall within a specific driving time from one another, before requesting and displaying those destinations on a map. Use of the service in an application that doesn't display a Google map is prohibited.
Looks to me like it's allowed so long as your application eventually displays that information on a Google Map, even if it's on another page.

I would like to develop a service, using Google Distance Matrix API, where a user can enter their current location and a map will be displayed showing how many other users from their group have addresses in the same general area. For privacy reasons, I do not want to show any other details (location, name, address etc.) of those other users just the number of people.
In order to ascertain this information I was intending to make a call to the API and displaying under the map of their area a message like "There are 5 other people within a 3 minute drive of your address".
Can anybody tell me whether this meets the API limitation:
The Google Maps Distance Matrix API may only be used in conjunction with displaying results on a Google map. It is prohibited to use Google Maps Distance Matrix API data without displaying a Google map
If my requirements of the API are not acceptable, could anybody suggest another publicly available API that I could use in its place?
Thanks!
Yournavigation Api gives you distance from given points.
Try this request example.
You can find their usage policy here.
They said that there are no limitations on usage, except those regarding overload:
The routing API is open and freely available for everyone under the condition that you don't overload the server. Overloading the server in this context means: more then 1 request per second for sustained periods of time. Bursting multiple requests for short time-periods is not a problem though
So I have successfully found directions to get some lat/long A to lat/long B using the Google Maps v3 directions api.
I want to be able to take a route from this api and give the user an option to view them on the google maps website.
I dont want to show the route on my website but only show the time it would take to get from A to B.
is this possible?
thanks!

The Directions API may only be used in conjunction with displaying results on a Google map; using Directions data without displaying a map for which directions data was requested is prohibited. Additionally, calculation of directions generates copyrights and warnings which must be displayed to the user in some fashion. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.
I am developing GPS based Location reminder in j2me. I am little bit confuse to which maps i use??.....Google maps & Nokia maps. Which one allows me good working... The working of my app are as follows :-
-User will provide a string to app to search a place of his/her desire.
-Then according to given string app will show a place on map by pointing marker on map.
-User can save that place or he/she can select a near by place rather than searched place by clicking on map or any other way.
-app will save that searched place coordinates & remind when it reached to near that place.
-When app remind to user about already stored place... that place should show on map by pointing an marker along with the how far he is from his destination.
The real choice here lies in whether to use a RESTful API like the Google Static Maps (or Nokia's RESTful Maps) or to use a native Java ME mapping library plugin such as the Nokia Maps API for Java ME. The latter has several major advantages:
Static mapping services such as the Google Static Maps API or Nokia's
RESTful Map API do not cache or tile the images when requested,
therefore each request involves a round trip to the server. If the
map on a mobile application needs to be refreshed at any time, using
a caching library will result in a reduction in network traffic after
around three maps have been displayed. An explanation of this can be
found here
As the name implies, Google's Static Maps API can only retrieve over
http static images for a requested coordinate point, image size,
image type and zoom level. Newer libraries offer additional
functionality out of the box offering dynamic Map content and touch
support, where the user can move around his/her current position,
zoom in, zoom out, modify the view mode to satellite or translate an
address to a coordinate point and show that on the map, among others.
This abstraction of the underlying functionality is hidden from the
developer so much less coding is needed in order to achieve the same
result .
Terms and Conditions for Nokia Maps are easier to fulfil than
Google - No legal restrictions of using the API outside a web browser
application or need to provide a link to the native Google Maps App
(if there is one), or to Google Maps (if there isn't one).
Nokia currently offer higher free daily request limits. Nokia Maps
API for Java ME supports up to 50,000 render requests per day and per
unique IP address (as of January 2012), for Nokia Developer
registered users (free of charge) while the limit for Google's Static
Maps API is currently 1000 unique (different) image requests per
viewer per day.
A couple of years ago there wouldn't be a choice, only RESTful solutions existed, but these days I would say a static http solution should only be used if you want a simple single image
As an abstraction of the underlying services, there are already a full set of examples to cover most of your use cases:
-User will provide a string to app to search a place of his/her desire.
-Then according to given string app will show a place on map by pointing marker on map.
http://www.developer.nokia.com/Commu...PI_for_Java_ME
-User can save that place or he/she can select a near by place rather than searched place by clicking on map or any other way.
Maybe you need to use a draggable marker:
http://www.developer.nokia.com/Devel...ples/#standard
Or react to the touch and find a Geocoordinate:
http://www.developer.nokia.com/Commu...PI_for_Java_ME
-app will save that searched place coordinates & remind when it reached to near that place.
This is known as geofencing and is covered by the Location API:
- http://www.developer.nokia.com/Resou...ty-events.html
-When app remind to user about already stored place... that place should show on map by pointing an marker along with the how far he is
from his destination.

For distance calculations, I guess you'd be after the ROUTING example

Now you could re-write and all these services from scratch using RESTful APIs (and then go about debugging your code) , but I'm sure you'll agree it would be much easier to use an existing, working and tested framework for the low level plumbing and then just write your code on top using the services.
It is possible to encapsulate RESTful service in Java ME. As an example, added below is a screenshot from an app encapsulating the suggestion service
It is just a lot easier when someone else has already done this work for you and placed it in a library.
I have a Google spreadsheet with one column of physical addresses, and I want to have a second column be the time in minutes to walk between the address in column 1 and a second address (as determined by Google Maps). Any recommendations on how to accomplish this task?
From my understanding of the Google Maps terms of service, they:
don't like people using their service as a "batch geocoder". This means that
you will need to throttle your requests (place delays between each successive request, to avoid the OVER_QUERY_LIMIT error)
it is against the terms of service to use the geocoder (and maybe the distance service) without displaying a map graphic
If you still want to proceed,
you need some way of extracting the address from your spreadsheet. I think there's a Google docs API that will help you do that. I also found some custom Javascript code that does that for you easily. I don't have a link anymore :(
once you have the addresses readable from the Google Maps Javascript API, you can call the distance or directions API to get the walking distance
then you need to save that back to the spreadsheet.
It sounds like a possible application for the Distance Matrix Service.
But you can only use it if you will be displaying a map
Use of the Distance Matrix API must relate to the display of
information on a Google Map; for example, to determine
origin-destination pairs that fall within a specific driving time from
one another, before requesting and displaying those destinations on a
map. Use of the service in an application that doesn't display a
Google map is prohibited.
I've started developing a small app which main goal is to draw a map using Google Maps API (v3), and to show business in the area drawn (bars, restaurants and so on).
I found the Google Places API that was supposed to be released this month but it hasn't been. As far as I know the point of that API is to offer results from the Google's database of business, so later we could put those business in the map.
However now I've found this sample which is using the AJAX Search API and Local Search Control for Google Maps to do the same thing.
So the question is, what is the point of the new Google Places API?
Thank you in advance!
The Places API returns a list of locations near a specific lat/lng, while the Local Search API allows for an arbitrary search of Google's database of business listings and other POIs.
