Google Map Api - How to know if a coordinates is accessible by pedestrian

I'm trying to figure if there is a way to ask the Google Map Api to know if a random gps coordinates like :
48,277373
2,4883883
Is accessible by pedestrian ?
It should be possible because if I ask Google Map to lead me in the middle of a river, it will lead me just on the nearest point before the water.
But I'm not sure how about I can get this information by providing the coordinates.
Thanks for your help :-)

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 Airport Search

I am trying to get a list of nearby airports, given a certain location.
You can do this through the google places api and using types=airport.
The problem is that Google Places is self-policing so any tom, dick and harry can call themselves an airport.
Is there any way to determine whether an airport is real - through google maps?
I know I could double check against an airports database but then I'd be best just using an external database and only use google maps to plot their locations!!
thanks
Geonames will give you airports eg. a search centred on Central Park New York with a radius of 25 kms.
http://api.geonames.org/findNearby?lat=40.776902&lng=-73.968887&fcode=AIRP&radius=25&maxRows=100&username=xxxxx`.
You will need to open a (free) Geonames account to make it work.
Such a search would be in your "external database" category but as far as I know, the entries are not self-certified, so are possibly more reliable than Google's from what you say.
To verify Google results against Geonames results would need to develop and code your own comparison algorithm.

help geocoding a vb.net dataset

i am looking to map a dataset of addresses on a map.
basically, i want the users to type a street name in my town and be able to see the houses that have signed up already on that street. so a pinpoint should show up on the houses that came up on the dataset.
at first i was thinking of just geocoding all the address and uploading the excel sheet into a database however, this wont work because new signups would then lack longitudes and latitudes
so what i am aiming to do is geocode the addresses on server side and then mapping the geocoded results
The Artem Google Maps control, available on Codeplex.com will let you geocode using the Google Map API from an address. If you have a very large number of records you want to geocode, I recommend MS Mappoint, which has a COM API that can easily be called from .NET.
