geolocation

问题 in out app we have a module where you can send time records with GPS location. In 40% of cases we have location problem because the module provides a location which is not real (sometime about 1 km away). When we have this cases we open Google Maps app and it give us perfect location, then again out app and not-real location. For getting the location we use this: Slider s1 = new Slider(); Dialog dlg = makeDialog("HIGH PRECISION LOCATION...", s1, null, 'a'); dlg.addShowListener((ActionListener

问题 I am trying to get my current location in react native, using react-native-geolocation I get latitude and longitude of my location. Now I want to convert them into the location's address without using the Google API key. Is there any way to convert latitude longitude into an address without using the Google API key? 回答1: There are many ways to convert lon/lat to address without using Google Maps API. Search reverse geocoding api and you'll find a bunch of alternatives. A few months ago I was

问题 Background I want to add a model manager function that filters a queryset based on the proximity to coordinates. I found this blog posting with code that is doing precisely what I want. Code The snippet below seems to make use of geopy functions that have since been removed. It coarsely narrows down the queryset by limiting the range of latitude and longitude. # Prune down the set of all locations to something we can quickly check precisely rough_distance = geopy.distance.arc_degrees

问题 I'm trying to do some things with geolocation. I want to get back the geolocation latitude and longitude in one variable as array. It doesn't work. I think the first line in the code is the problem. Is it possible to get the value like that (with return)? startingPoint = navigator.geolocation.getCurrentPosition(onGeoSuccess); function onGeoSuccess(position) { start['lat'] = position.coords.latitude; start['lng'] = position.coords.longitude; return start; } Is there a better solution? I don't

问题 I'm using React Map GL, and I want to put the latitude and longitude of the user Returning the component like this: export default geolocated({ positionOptions: { enableHighAccuracy: false }, userDecisionTimeout: 5000 })(Layout); I'm tried to use react-geolocated but it's returning null coords. I want to get these informations when the component mounts, that's the code: componentDidMount() { console.log(this.props); if (navigator.geolocation) { const viewport = { ...this.state.viewport,

问题 I am using below code to get the track the location of user. This works proper when my application in foreground. But when my application move to background it stop working and i can not get any location. import 'dart:async'; import 'package:permission_handler/permission_handler.dart'; import 'package:geolocator/geolocator.dart'; class FetchLocation { var geolocator = Geolocator(); var locationOptions = LocationOptions(accuracy: LocationAccuracy.high, distanceFilter: 10

问题 I've got a webView for my website that needs to access the user location, and it does that by pressing a button and displaying the position in a form. I need a way from the webView to ask the user to turn on the gps if it's off when clicking on the button (it has id="locate button" ). How can I do that from Android studio? My code: MainActivity.java public class MainActivity extends AppCompatActivity { private WebView webview; @Override protected void onCreate(Bundle savedInstanceState) {
