geolocation

When utilizing Apache Cordova's cordova-plugin-geolocation, specifically with watchPosition() I am encountering difficulties on at least iOS 8.1.3 through 8.3. What is happening is that when a user is moving, the coordinates work just fine and are continuously updating. However when the user stops for a few moments (say the timeout that is set), a timeout error is thrown. The second the user moves again the coordinates are working. We cannot increase the timeout too much for fear that users will legitimately lose reception and have to re-record their field boundaries (agricultural application)

I have a PHP script at the moment which allows users to enter a UK postcode. I was wondering if there was a way I could get their geolocation from the postcode they enter. (Through Google's API or something?) I have tried http://code.google.com/apis/maps/documentation/geocoding/index.html but it requires a full address, whereas I only have a postcode. Help would be appreciated, thanks :) Peter You could check out the Yahoo PlaceFinder API Heres an example URL http://where.yahooapis.com/geocode?q=BL12DD&appid=[yourappidhere] I have used this in the past and found it to be somewhat accurate.

I have a set of 900 Latitude and Longitude Coordinates-- I need a relatively simple method for finding the 'State' referred to by these coordinates. If it helps, the data is in excel. Google provide a Geocoding service. Part of this is reverse geocoding which converts geographic coordinates into a human-readable address including States. This Demo illustrates what can be done. There are limits to what you can do with this service. Axel Kemper Try to use the average values as provided here . With a bit of luck, most of your 900 coordinate pairs belong to the state with the nearest center.

I've been trying to answer this myself but I can't find it, would any of you know? Truth is they probably scraped it from someone else initially. See Yelp, Maps (Gmail,Yahoo,Bing,etc), Citysearch, etc. Yahoo has some flexible GeoData APIs. Some of the above also have APIs (including FourSquare) which would make this easier, but is most likely against their terms of service (TOS). Please post back if you find out otherwise, or a viable solution. Users generate/add the locations 来源： https://stackoverflow.com/questions/2216198/how-or-where-does-foursquare-gets-its-geodata-from

What do people use to geo-locate a persons IP to determine the city they are in? I've tried the built in functionality of Google API but its geo-location database seem spotty. http://code.google.com/apis/ajax/documentation/#ClientLocation Anyone use any other service for geo-locating with success? The most stable company I've seen that does it is MaxMind . A buddy of mine is using is with success. There is a community-based Geotargeting service from hostip.info . They have a nice clean API for Geotargeted IP Address Lookup. They've got over 8.6 million entries in their database. Example: http:

I search with the twitter API all the public tweets with "4sq.com": http://search.twitter.com/search.json?q=4sq.com so I get all the check-in on Foursquare that actually shared on Twitter. {"created_at":"Sun, 08 Jan 2012 20:05:27 +0000","from_user":"fenavergara","from_user_id":50876086,"from_user_id_str":"50876086","from_user_name":"Fernanda Vergara Ch","geo":null,"id":156104246239051776,"id_str":"156104246239051776","iso_language_code":"lt","metadata":{"result_type":"recent"},"profile_image_url":"http://a2.twimg.com/profile_images/1708744785/image_normal.jpg","profile_image_url_https":"https:

i am using a geo_distance filter with tire in my query and it works fine: search.filter :geo_distance, :distance => "#{request.distance}km", :location => "#{request.lat},#{request.lng}" i expected that the result would somehow include the computed distance to the geo-location that i used for my filter. is there a way to tell elasticsearch to include that in the response, so that i don't have to calculate it in ruby for every result? == UPDATE == i found the answer in a google group: search.sort do by "_geo_distance", "location" => "#{request.lat},#{request.lng}", "unit" => "km" if request.with

My project requests Geocoding API for coordinates and correct full addresses in Odessa, Ukraine. I could request response in Russian or Ukrainian language adding language=ru ( language=uk ) parameter to the HTTP request. Starting today I get street name in Ukrainian in response, no matter which language I specify in request. Examples. Request for Russian: https://maps.googleapis.com/maps/api/geocode/json?address=Пушкинская, Одесса, Украина&language=ru Relevant part of the response: "results" : [ { "address_components" : [ { "long_name" : "Пушкінська вулиця", "short_name" : "Пушкінська вулиця",

I am trying to plot some information that shows full population and then a subset of that population by location on a map. I've seen data visualizations that use concentric circles or 3-d inverted cones to convey this. I just can't figure out how to do it in ggplot / ggmap Here's a free hand version in Paint that shows a rough idea of what I'm looking to do: Here's a rough piece of data for an example: > dput(df1) structure(list(zip = c("00210", "00653", "00952", "02571", "04211", "05286", "06478", "07839", "10090", "11559"), city = c("Portsmouth", "Guanica", "Sabana Seca", "Wareham", "Auburn"
