How to know if there are any seaports around the input address with a radius of 1km in Google Maps API - asp.net

I have 1 input address inside Textbox. How to know if there is a Ocean Port around that address within a radius of 1km? I am using Google Maps API v3. However I found no documentation regarding it.
Any help is worth it. Thank you!

How to get place information using Google Knowledge Graph using Latitude and Longitude ?

I want business description using google API or wikidata API.
As shown in above image I want to access description (which is highlighted in red circle.) and store it into application database.
What I tried till now, I used google place API to get the place information, using that I am able to get information like review,rating,opening hours. But I am not able to get that information which I have mention in above image. But I do not know how to get that information using Wikidata api or Google Knowledge Graph api.
Can any one suggest me that how can I use that API to get that information.
Any help would be highly appreciated !
Thanks,
I'd also be keen to know if this is possible. For example, with a bounding box. 4 coordinates, might it be possible for Google Knowledge or another API to give me a summing up of the place.
For example: bbox=4.721375,52.290843,5.070190,52.399905
Might return information and history on the city of Amsterdam. Like when you type into Google Search "Amsterdam".
Just a thought. I have previously accomplished this with a very manual combination of Overpass API (related to OSM) and Freebase.
I just found this: Find a place description in Freebase using latitude and longitude?
So, it can be done. And it is already documented.

Google have a service called Geocoding - you send a request including an address, a google.maps.latLng, or a Place_ID and it returns an array with all three of them. they explain all about this here.

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.

Google has started highlighting search areas in Pink color. Is this feature available in Google Maps API 3?

Since Jan 2012, Google has started highlighting search areas in pick color. See the details here:
http://googlesystem.blogspot.in/2012/01/highlight-areas-in-google-maps.html
Does anyone know if this can be programmatically done using google maps API 3? I would want to show my cities in the map highlighted as shown in the link above.
I have already tried the Geocode API where I search for a city. That API only gives me the lat and long information. It does not help me in plotting the city boundaries.
No. It's not available in the API.
(It may be available in the future. Features of Google Maps do migrate into the API, but Google don't make announcements in advance and no-one has a crystal ball.)
You would need to find the city boundaries and draw the line yourself. Boundary data is almost certainly public-domain for the US. Other jurisdictions may not be so forthcoming.
Although a very old post my answer might help somebody out there as am landing on this post every time I query for bounding box:
Yes we can get the bounding box coordinates that google is using to highlight a region using Googles geocoding service. check for the response of the API call in the below sample from Google.
