geolocation

问题 I need put information about place, where is iPhone now, to UILable in my screen. [Country][City][Street] and maybe coordinates [lat][lng]. For example in my UILable should be: Your location is German, Berlin, Tiergarten Can someone show me really simple code how can i get such information that put in my UILable? 回答1: The MapKit framework (part of iPhone OS 3.0) provides this for you. Specifically the MKPlacemark object, which you can obtain for a set of co-ordinates using an

问题 I have a csv file holding longitude and latitude for some of the records (otherwise it's " "). Now I want to use logstash 5.1.2 to ge the data into elasticsearch 5.1.2. I've written the following conf-file but the location field is still mapped to text. input { file { path => "/usr/local/Cellar/logstash/5.1.2/bin/data.csv" start_position => "beginning" sincedb_path => "/dev/null" } } filter { csv { columns => ['logtime', 'text', 'user', 'country', 'location'] separator => "," } date { match =

问题 I've been building a google map where users share information plus their current location in a form. I want to automatically fill the lat, lng fields in my form with the Geolocation function. The only thing I cannot do is that last step. Here is my code: <script src="https://maps.googleapis.com/maps/api/js?V=3.exp&key=wootwootwootwoot"></script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> <script> var map; function initialize() { var mapOptions = { zoom

问题 I'm calculating small angle between large vectors in 3D. I use common formula: double angle = atan2(norm(cross_product), dot_product); In general I'm trying to get angle between my vector on Earth and Normal to Earth elipsoid(gravitational vector) to align my vector to gravitational vector. I store my vector in ECEF coordinates. And values are about: normal_ecef[2853169.5286430484, 2139463.4659523461, 5254245.1411450412] v_ecef[11.4893763275, 9.3040978122, 16.5129716340] cross_product

问题 I really want to know how do I can update the position of the user in the map while the UWP app was running in bakground Here is my code right now private async void PinPoints() { //Pin point to the map Windows.Devices.Geolocation.Geopoint position = await Library.Position(); double lat = position.Position.Latitude; double lon = position.Position.Longitude; //Geoposition alttest = await Library.Temp(); //alt = alttest.Coordinate.Altitude; DependencyObject marker = Library.Marker("" //+

问题 I succeeded to determine if the user is within a certain distance of a single marker. What I want to do next is to have the script check, if the user is close to one of multiple locations stored in an array. If yes, I want to have the script trigger the event specific to the respective location. Here is my code: <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?libraries=geometry&sensor=true"></script> <script> var map, GeoMarker; function initialize() { var

问题 I am creating a c# form application(It's important to note that it's not a mobile app cause I think that is part of the issue). I am trying to use the Windows devices geolocation libraries and I am running into the issue that the code given on the microsoft website doesn't work. GeolocationAccessStatus accessstatus = await Geolocator.RequestAccessAsync(); This code should work fine but I get the error "IAsyncOperation does not contain a method for getawaiter and no extension method accepting

问题 I'm trying to write a world clock app that returns the sunrise and sunset information for a given time zone. The thinking is that the user will either specify the GMT offset or give the time zone explicitly. Then the application will look up the latitude and longitude using the java.util.TimeZone found (or possibly given the GMT offset). I realize the time zones are usually not a very accurate way to get geolocation information since they are mostly based on political borders, but it seems

问题 Im wanting to know if there is any commercial free map display options for Silverlight projects these days? I tried to run DeepEarth and it just wouldnt play for me in SL5. Im keen to run OpenStreetMaps so we can deploy it commercially without licensing issues. Any advice would be appreciated.
