geolocation

问题 In the depths of an application I need to use the Geolocation API. var that = this; if(Modernizr.geolocation){ $(this).addClass("loading"); navigator.geolocation.getCurrentPosition(function(position){ that.handleGeoSuccess(position); // defined elsewhere },function(error){ that.handleGeoError(error); // defined elsewhere }, {maxAge: 0, timeout: 1000}); } else { that.handleGeoError(); // defined elsewhere } This happens inside of a click-event. Chrome (25.0.1364.155) prompts for permission but

问题 I'm explaining with an example to achieve my result. I have a users table. Each user has their location with latitude and longitude on the database. I'm using firebase database. So the DB looks like: users { user-id{ location{ latitude longitude } } } I need to find users within a circle using my current location. I've looked into geolib and found a method isPointInCircle . But using this, we need to iterate users data and needs to call this method on each loop. I need to avoid this multiple

问题 The next image was taken from www.Trimaps.com (I hope it's allowed to use images here, if not, please tell me and i'll remove it immediately). These images explain perfectly what i'm trying to accomplish. I have all the data one would need: Latitude/Longitude (in decimal values) of 4 corners of the desired area (from Google Maps). A beautiful custom image of a mountain (similar to the right image). All i need is the math. I've tried all the formula's, scaling/ transfomations, you name it. I'm

问题 I apologize for the broad question. But I have a list of IP addresses, and would like to connect them to the companies they came from. I'm not interested in identifying personal IP address information (probably not even possible) but I figure there must be a way to identify if the IP address is associated with a large corporation. Whois.net usually only gives the ISP name, not the company name. Thank you 回答1: The http://ipinfo.io API (my own service) returns the company name as the org field:

问题 I am working on an application where i need to know the users location: country, state/province, and city/town. Then I want users to interact in some way based on their location: country, state/province, or city/town. However the geocoder gives me these locations in the language that the phone is set to. For that reason I can't accurately compare strings with other users that are in the same country, state/province, or city/town, if their language is set differently. 1 solution for countries

问题 I am trying to create an app to find the exact location of IP address. I did some research on IP addresses and many more. But whenever I try to locate an IP address it provides the location of Internet Service Provider. I want to track the exact geolocation or long & lat of that place. So can anyone help me out to let me know how to find the geolocation of Dynamic IP address 回答1: The information upon which such a service might (hypothetically) be based is not available. Ergo, the ISP level

问题 Is there are way to fetch location/coordinate specific public posts using the facebook search api ( https://graph.facebook.com/search/?q=KEYWORD&type=post ... )? I want this to be a general search query, without any user authorization. I tried using https://graph.facebook.com/search?type=location&center=37.76,-122.427&distance=1000&access_token=... , but this requires access_token and returns objects(not posts) posted only by friends of the user whose access token is used for querying. I also
