I am trying to implement a simple script on a site that will return base64 encoded information from google's ajax API.

Is there an easy way to determine which hemisphere a user is in?

阅读更多关于 Is there an easy way to determine which hemisphere a user is in?

问题 I'm working on a project which includes seasonal content, and we're thinking of determining the user's location to work out what season it is for them. The obvious way of doing this is to Geo-locate their IP, then grab the latitude. > 0 is Northern hemisphere, and < 0 is Southern. I'm happy to go that way - though it seems a bit of a waste to pinpoint an IP to an exact location, just to determine which half of the planet they're on - but I thought I'd throw it out there in case anyone has any

Google's Geocoder returns wrong country, ignoring the region hint

阅读更多关于 Google's Geocoder returns wrong country, ignoring the region hint

I'm using Google's Geocoder to find lat lng coordinates for a given address. var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': address, 'region': 'uk' }, function(results, status) { if(status == google.maps.GeocoderStatus.OK) { lat: results[0].geometry.location.lat(), lng: results[0].geometry.location.lng() }); address variable is taken from an input field. I want to search locations only in UK . I thought that specifying 'region': 'uk' should be enough but it's not. When I type in "Boston" it's finding Boston in US and I wanted the one in UK.

I want to implement this in ASP.NET. I don't have any idea about how to do so, unfortunately. Michael B. Here how it is done in asp.net Request.ServerVariables("REMOTE_ADDR") Get a copy of IP adress database by location here http://www.maxmind.com/ Shoban Why not use Google Analytics ? You will get more than what you need. Alternatively you can get the client's ip and use service like ip2location to get the location. Check this similar question as well. finding clients location in asp.net page. There are a few free web services out there which provide IP-to-location services. For instance:

How to determine if an IP address belongs to a country

阅读更多关于 How to determine if an IP address belongs to a country

How would i determine the country that a spcific IP address is originating from using c#. I need to use this to check if connections originate from a specific country. You can use this SQL data in your project to determine that: IP address geolocation SQL database . Download that data and import it into your database to run checks locally. Or you can use their free API that returns XML containing the country code and country name. You'd make a request to the following URL with the IP address you wanted to check, as seen in this example: http://ipinfodb.com/ip_query_country.php?ip=74.125.45.100

How can I use HTML5 geolocation in angularjs

阅读更多关于 How can I use HTML5 geolocation in angularjs

How can I use HTML5 geolocation in angularjs? I can get it using HTML5; but how can I pass it to angularjs scope in controller? any sample jsfiddle will save my day! you can do something myApp.controller('fooCtrl', function($scope){ if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position){ $scope.$apply(function(){ $scope.position = position; }); }); } }) you need to do $scope.$apply to trigger the digest cycle when the geolocation arrives and to update all the watchers. I'd suggest abstracting this into a service so your controller doesn't have a dependency on

iOS 6 breaks GeoLocation in webapps (apple-mobile-web-app-capable)

阅读更多关于 iOS 6 breaks GeoLocation in webapps (apple-mobile-web-app-capable)

I have an app that does a simple textbook navigator.geoLocation.watchPosition(...) that works great in iOS 5.x both in Safari and as a web app (using apple-mobile-web-app-capable meta tag). However, in iOS6, GeoLocation does not work in the webapp. It still works in safari as expected, but when I run the webapp, it prompts me for location permission, then silently fails. I see the location icon, but no events are thrown from watchLocation. I get no error events or any location events. Has anyone run into this? Any workarounds? It's definitely iOS6 specific and also specific to the apple-mobile

问题 We recently tested our application against android API level 14 and 15. We started development targeting minimal SKD Version 8 and excluding tablets (3.x). With 2.x everything works well but when running the app on a 4.x droid it crashes at the point we're obtaining user's location.

Detecting whether a GPS coordinate falls within a polygon on a map

阅读更多关于 Detecting whether a GPS coordinate falls within a polygon on a map

As stated in the title, the goal is to have a way for detecting whether a given GPS coordinate falls inside a polygon or not. The polygon itself can be either convex or concave. It's defined as a set of edge vectors and a known point within that polygon. Each edge vector is further defined by four coordinates which are the latitudes and longitudes of respective tip points and a bearing relative to the starting point. There are a couple of questions similar to this one here on StackOverflow but they describe the solution only in general terms and for a 2D plane, whereas I am looking for an
