I need to find if the given zip code is within the required radius. For example, if the user has entered 20910, it should be able to determine if it's within 5 mile radius of 20814. Is there a way to do it? Google API or something? Please help.
I'm using C# as the programming language.
I think it's called the havershine formula...

I would like to take a longitude and latitude of a user and determine if they are within a set boundary of property line on the map similar to the rectangles symbolizing buildings.I have looked into using CLGeocoder which returns an address but I would like to be able to determine if the user is within a park, or a property, a neighborhood or even a building which may have multiple addresses within it. What is the best way to go about doing this thank you.
I've searched for solution for that problem on here-api documentation but I can't really find it out ! I'm starting doubt if this even possible.
Ok so basicly what i need to know for now:
1. Is this even possible on this platform ?
2. Using exactly which 'module' (eg. PLATFORM DATA EXTENSION,BATCH GEOCODER)
There is no straight solution to get all districts in a city since district concept varies from one place to another(country-specific). Still you can try one of the below options:
administrative-areas-buildings category in places api
city-town-village category in places api
retrieveAreas mode in geocoder api (apply bbox or increase the radius of prox parameter and see if it works for your location)
Search Text in geocoder can also be used if you are search for districts which match a regex
You can check if the above 1) and 2) are applicable to your location using https://places.demo.api.here.com/places/v1/categories/places?at=41.8369%2C-87.684&app_id=DemoAppId01082013GAL&app_code=AJKnXv84fjrb0KIHawS0Tg
I'm trying to research a topic and I need to get all tweets within 2013 and 2015 and a specific location for two keywords.
I tried to get the results via Advanced Search but I allways get no results.
I tried:
cannabis near:"España" within:15mi since:2013-10-07 until:2015-01-01
cannabis near:"Spain" within:15mi since:2013-10-07 until:2015-01-01
Basically, I have a database of scraped press articles sorted by date from a bunch of sources, and I want to know how the agenda of this news sources have an impact on the social media conversation.
I could do it over Reddit if it was the case for the US, but there's no Spanish alternative (well, we have Meneame, but the user base is very left-leaning and I think it will be very narrow).
So I wanted to either scrape the search results or get them via API, but It's not working, and AFAIK I can't do anything similar with Facebook.
One way to achieve this is by using Twitter's geocode operator. In the example below i took Madrid as a center and covered a radius of 600km around it like this:
(canabis OR cannabis) geocode:40.4381311,-3.8196196,600km since:2013-10-07 until:2015-12-31
Try it...
The syntax is as follows:
([your_boolean_search_query]) geocode:[latitude],[longitude],[radius]km since:[] until:[]
one easy way to find latitudes and longitudes of locations is to use Google Maps. Simply navigate to a place using the search box and then copy the latitude and longitude element from the URL line in the browser. Here it is for Madrid. The latitude and longitude are right after the # sign, separated by a comma:
https://www.google.com/maps/place/Madrid,+Spain/#40.4381311,-3.8196196,54451m/data=!3m2!1e3!4b1!4m5!3m4!1s0xd422997800a3c81:0xc436dec1618c2269!8m2!3d40.4167754!4d-3.7037902?hl=en
Try it...
I'm trying to search pages which location city equals to xyz.
For example find page Guiness in city = Wroclaw, it looks like this:
/search?q=Guiness&type=page&city=Wroclaw
But it doesn't work ?!
I tried many different ways.
I think the problem is in that the location is complex type, but I can't find in documentation how to search by complex type :(.
Hope help will came soon.
Thanks !
It's clearly documented what is possible with the /search endpoint:
https://developers.facebook.com/docs/graph-api/using-graph-api/v2.5#search
You can't use other parameters than outlined there. Either this would be
/search?q=Guiness%20Wroclaw&type=page&fields=id,name,location
or search for a place with center coordinate and a distance:
/search?q=Guiness&type=place¢er=52.231804,21.007973&distance=5000
I am looking to use Google Places autocomplete to help user search for places near him/her. When using autocomplete in the example below, I get establishment that are very far from the location.
https://maps.googleapis.com/maps/api/place/autocomplete/json?input=pizza&types=establishment&location=37.340871,%20-122.029642&rankby=distance&key=mykey
I assume Google considers the popularity of the establishment in the result set. My question: is there a way to get back the list sorted by proximity to the location, i.e. "turn off" the popularity index? (and to get similar functionality to the nearbysearch with autocomplete) ?
Why not just using nearbysearch? because nearbysearch does not perform well when only part of the name is entered as keyword ( I assume nearbysearch assume the 'keyword' parameter is the complete word).
Thanks for your help!
