geolocation

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . My requirement is to get the Latitude and Longitude value for a particular zip code. Is there any API that I can use to get these information. As I am working in a company so the requirement is coming for our team is to find the latitude and longitude value for a particular zip code. So we were thinking to build a

问题 My client would like me to implement geolocation in a mobile application. He want me to use a map which is quite deformed (definitely not a google-like map). Is it an easy way to transform the GPS coordinates into the coordinates on that deformed map? I get the coordinates (X0,Y0) from the GPS -> I need the location on my client's map (X1,Y1) 回答1: Dude, you should try http://trimaps.com. It does exactly what you are looking for! 回答2: You need to know the mapping from the client map to real

问题 Right this is confusing me quite a bit, i'm not sure if any of you have noticed or used the "my location" feature on google maps using your desktop (or none GPS/none mobile device). If you have a browser with google gears (easiest to use is Google Chrome) then you will have a blue circle above the zoom function in Google Maps, when clicked (without being logged into my Google Account) using standard Wi Fi to my own personal router and a normal internet connection to my ISP, it somehow manages

问题 I am working on an application where I would like to track the position of a mobile user inside a building where GPS is unavailable. The user starts at a well known fixed location (accurate to within 5 centimeters), at which point the accelerometer in the phone is to be activated to track any further movements with respect to that fixed location. My question is, in current generation smart phones (iphones, android phones, etc), how accurately can one expect to be able to track somebodies

问题 I have an application, and I'm using the Google Javascript Geocoding API to fetch lat/lng for an address. The code goes something like geocoder = new google.maps.Geocoder() geocoder.geocode({ 'address': query }, function(results, status) { addresses = {}; $.each(results, function(index, value){ addresses[index] = {"lat":value.geometry.location.$a,"lng":value.geometry.location.ab} }) }); All is fine and dandy, but the thing is that the property names of the location object periodically change.

问题 I want to build an app that centers around getting the user's current location and then find points of interest(such as bars,restaurants,etc) that are close to him/her via the Google Places API . Upon searching the web for a place to start I came across some tutorials that use the LocationManager class and some others that use Google Play Services in order to find the users location. On first sight both of them do the same thing, but since I am new to this I got a little confused and I don't
