I am trying to geocode NYC high schools by using the Maps Geocoding API and the unique BN code assigned to each high school. For example, typing K733 into Google Maps results in a marker on MESA Charter High School in Brooklyn, NY. However, when I use the API url like so:
https://maps.googleapis.com/maps/api/geocode/json?address=K733
I keep getting "ZERO_RESULTS". I've also tried using the Places API and I've gotten the same results. Can anyone point me in the right direction? Is it even possible to pull this information from Google Maps?
It not possible to use unique BN codes for Maps Geocoding API because the address component requires postal address
address — The street address that you want to geocode, in the format
used by the national postal service of the country concerned.
Additional address elements such as business names and unit, suite or
floor numbers should be avoided. Please refer to the FAQ for
additional guidance.

I used the twitteR package to extract data from Twitter API, and now I try to filter data by country name.
Most geocode packages are designed for inputting the real address and returning the corresponding geocode, but my needs are just the opposite.
For example, when I input c(38.897957, -77.036560), the result is "Whitehouse, D.C., U.S."
I ran into the revgeo package which performs Reverse Geocoding with the Photon Geocoder for OpenStreetMap,Google Maps, and Bing .
By default it uses photon which provides free data.
I'm using the example from the package itself.
require(revgeo)
revgeo(longitude=-77.0229529, latitude=38.89283435)
#"700 Pennsylvania Avenue Northwest, City Not Found, Washington, D.C., 20004, United States of America"
You can give it a try.
This blog below does mention that some locations are missing form their dataset, and it throttles down the speed after certain number of queries. There are other good pointers at the blog. https://towardsdatascience.com/reverse-geocoding-in-r-f7fe4b908355
I am developing a website in ASP.NET in which I need accurate coordinates of properties and populate their markers on Google Maps. I read the Google Maps API documentation and it doesn't accept business names or house numbers. So if I add 5 properties on Moseley Road with postal code WR2 6NJ, they all receive the same coordinates at the beginning of the road, where as they're all separate properties with separate coordinates, for example: Arthur Amos Associates Ltd, Moseley Farms etc.
How can I increase the accuracy so each address gets it's own coordinates? I tried the ROOFTOP and street_address parameters but they didn't help. Do I need to get Google Maps API for Work to get this level of accuracy?
Thanks.
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.
I am using Google Maps API v3 Distance. It has worked well for the majority of the addresses in my database. However, it seems like some addresses just aren't available in Google Maps, and it seems to pick the closest street address match which could be way off. I would expect Google Maps in this case to provide an answer based on city and zip. Does anyone have a solution? I've thought of double checking mathematically by geocode and checking Yahoo maps(or other sites) for the ones that are way off but that adds processing time and is not a very elegant solution. There must be some setting I'm missing or other such work around.
Thanks!
BTW shout out to the new Json Serializer! Well it was new to me anyways.
How are you formatting the address you are sending ?
I've used the Google Maps API to do some reverse geocoding and if a street could not be found (due to a typo or what have you) Google would return the lat lng for the historic town center.
I structured addresses as Country, city cityzip, street nr.
You should use the location_type of the geometry object to determine what accuracy was returned. I suggest checking to see if the returned resulsts indicate whether a result is anything other than ROOFTOP or RANGE_INTERPOLATED.
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.
