google maps distance matrix - asp.net

I am using the Google Distance Matrix to determine the distance between the user and our centres.
This works fine, however the documentation states:
"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."
But I am unsure how to "request and display the destinations on a map"
Is it possible to show the map in my application with the directions? If so where do I start? I have been looking but have been unsuccessful so must be searching for the wrong thing.

Nearest Shops Feature by using Google Places API

I am trying to develop the feature in my website to search the nearest Stores for the given location/address.
For example.
http://www.tesco.com/store-locator/uk/
After I have done some research, I think, I need to use the Google Places API to locate the nearest places. I have tested with some examples and it's working.
However, I don't know how to upload my chain of stores onto the Google Map and how to find the nearest stores (only mine, not other stores). I couldn't find a feature to upload my places onto the Google Places by using their API.
Could you please guide me how I could achieve it? Thanks.
I am attempting a similar feature.
First, you will need to upload your business locations to google. I think this is an important step it getting your places to show up on google maps. You can do that here: https://www.google.com/local/manage/#/list
After uploading you can download all of the locations in csv format. Once you have all of your locations in csv format you can parse the data and create a list of addresses to search.
Once you have your addresses you can use google's distance matrix api https://developers.google.com/maps/documentation/distancematrix/
you can search up to 100 places and get back a distance result for each location. Finally you can parse the distance results to find the closest location.
A few drawbacks here. There is a URL length limit of 2000 characters. If you are searching a lot of places this will fill up fast. Also, the free version of the API has a limit of 100 places per search and a maximum of 100 places per 10 seconds so if you have a lot of places or a lot of users this will be an issue.

Google Maps API and ASP.Net

I am new to Google Maps API and I have a requirement to integrate Google Maps API with an ASP.Net application. Is there a Google service where in I can input a UK postcode and radius as input parameters and get results only, without the map.
For example if I search for solicitors in a particular area like Z1 1XY (not real post code) with a radius of 5 mi, can I get the results of all solicitors with the postcodes 5 mile radius? Is there any service that would return the result set only? I know GeoCoding does something similar but can I provide radius as one of the input parameter and get results.
Any help would be appreciated. Thanks in advance.

The Geocoding API may only be used in conjunction with a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.

yes, you can use the Google Geocoding API to do address lookups (in this case postcodes). The response contains lat/lon co-ordinates which you can then subsequently use as the epicenter of your search to find items within a radius. Have a look at this blog post on how to use the DbGeography in .NET to perform radius queries based on lat/lon co-ordinates.

Is it possible to merge Google Places API with Google Geocoding API?

I am in the process of building a booking system and I'm wanting to do a lookup, based on a text field, that searches both businesses and addresses.
For example, a user is presented with an Input Box that asks them to enter a location. I want it to support Businesses and Addresses.
My current implementation uses the Geocoding web service, but it's unable to find businesses, so I need to bring in the Places API.
I also need to find the distance between these places using the Google Distance Matrix Web Service.
I thought I'd solved my problem by JUST using the Google Places API, but not all addresses are listed on it.
Any ideas / previous experience is greatly appreciated.
You can use both of these on the page, and place a condition for an unsuccessful search on one (i.e. missing or empty variable) to trigger the other.

ASP.NET/Silverlight Location Points on Google/Bing Map

I realize that the question is pretty complicated and may require much research. Hope anybody can help me to get useful resources to achieve my goal.
I want to have a Google or Bing map on my ASP.NET 4 application (C#) to display all my logged in users as points on the map.
I understand that this involves five major problems
Get the location of the device (most likely standard laptop with IE9 browser) based on its unique IP address.
Integrate Google or Bing map with ASP.NET or Silverlight application.
Display the right portion of the map with the right Zooming depending on logged-in users locations.
Finally, mark the addresses as points on the map.
Note that the locations points should be dynamically reflected when any of the locations is changed.
The database is implemented using SQL SERVER 2005/2008R2
There are geo location services that can give you the latitude and longitude given an ip address.
As you mention you would be storing these in a database, getting all the current users would be simple database call.
Integrating a google map into a html page is very simple. You would only have to emit the necessary javascript from your page.
You should mark the points on the map first.
Google maps api has calls to fit the map to show all current points(fitBounds). I am guessing bing would have something similar.
To reflect the current points, you would have to fresh your locations from the database. I highly recommend an ajax call that returns json and using that to replot the points.

Using the Googlemaps Geocoder and Storing the Data

I am building an Events site in which the address of a given event will be stored to be used within a map on the page. Whilst viewing an Individual Events' page i would like to provide a list of similar events on side of the page. I would also like to rank this list by distance and display a small map with a marker on it for each item on the list.
I was thinking of Geocoding the Events address upon content input and then storing this data within the sites database. Doing this would allow me to calculate the distance of an event on the server and then provide an ordered list to display.
My question is this:
Would this violate the Googlemaps Terms of Service?
These terms:
"the geocoder for any purpose other than obtaining locations that will be displayed using the Google Maps APIs is a violation of the Terms of Service. You may use the HTTP geocoder to geocode addresses outside of your Google Maps API application so that they may be cached and later displayed using one of the Google Maps APIs, but locations obtained using the Geocoding Web Service may not be used by any other application, distributed by other means, or resold."
Suggest that storing the data is not a problem but i am unsure that the process of ordering the list by long lat would not result in a violation.
Any advice would be greatly appreciated.
As long as the map your refer to in your question is a Google Map and you are using the geocoded data to display features on a Google Map, you are fine. The client-side google.maps.Geocoderdev-guide is intended for dynamic requests that are based on real-time user interaction that drives a need to perform on-the-fly geocoding. But Google encourages you to consider using the Geocoding Web Servicedev-guide on the server-side, when you wish to pre-geocode static addresses or coordinates prior to using the response values on a Google Map. Storing those values is assumed.
It is common to perform some form of post-response/post-storage processing on those values, just like the ordering by distance that you describe, to fit whatever use case is needed to populate your map with the appropriate data. I understand you want to be careful to remain within the TOS, but what you describe sounds pretty standard.
