geolocation

I've been searching everywhere for a clear example of how to use the ch.hsr.geohash to search for nearby locations. I mean, I just need to implement the following situation: 1 - I have a Long latitude and Long longitude. 2 - Convert this latitude/longitude to hash. (I believe it's done by using "GeoHash.withBitPrecision(latitude, longitude, 64)" but I'm not sure what precision is here. I suppose 64bits would be to have the same precision as long 3 - Retrieve a list of latitudes/longitudes within 100km distance (I have no idea how to even start it using geohash) 4 - Query objectify objects

I am getting coordinates with Windows Phone GeoWatcher like this private GeoCoordinateWatcher _watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High); _watcher.MovementThreshold = 2; // Threshold Value _watcher.PositionChanged += Watcher_PositionChanged; //Registering Watcher Position Change Event _watcher.Start(); // Starting Watcher //Watcher position Change Event private void Watcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e) { var coord = new GeoCoordinate(Convert.ToDouble(e.Position.Location.Latitude.ToString("0.00000").Replace(",", ".")), Convert

I have a geojson file containing a list of locations each with a longitude, latitude and timestamp. Note the longitudes and latitudes are multiplied by 10000000. { "locations" : [ { "timestampMs" : "1461820561530", "latitudeE7" : -378107308, "longitudeE7" : 1449654070, "accuracy" : 35, "junk_i_want_to_save_but_ignore" : [ { .. } ] }, { "timestampMs" : "1461820455813", "latitudeE7" : -378107279, "longitudeE7" : 1449673809, "accuracy" : 33 }, { "timestampMs" : "1461820281089", "latitudeE7" : -378105184, "longitudeE7" : 1449254023, "accuracy" : 35 }, { "timestampMs" : "1461820155814", "latitudeE7

with this code: if (ionic.Platform.isIOS()) { cordova.plugins.diagnostic.switchToSettings(); } else { cordova.plugins.diagnostic.switchToLocationSettings(); } I can open the native device configuration to mark the geolocation. but I do not know how to do it when the user turns on the geolocation, it simply executes that code but does not get an answer from that. I would like (if possible) to know if the user turned on the geolocation or not. how can I do it? I am using ionic1 , although I suppose that the operation for this solution would apply to any version. thank you very much.

I have created collection and a object is looks like this. [_id] => MongoId Object ( [$id] => 53087f483b15eaeb6c3c9869 ) [time_from] => 2014-02-22 00:00:00 [time_to] => 2014-02-22 00:10:00 [checkin] => Array ( [0] => Array ( [time_frame] => 2014-02-22 00:00:56 [user_id] => 1 [loc] => Array ( [type] => Point [coordinates] => Array ( [0] => 73.43 [1] => 42.22 ) ) ) [1] => Array ( [time_frame] => 2014-02-22 00:00:56 [user_id] => 2 [loc] => Array ( [type] => Point [coordinates] => Array ( [0] => 73.10 [1] => 42.97 ) ) ) } I need to create "2dsphere" index for 'loc' field. The checkin field has all

I want to calculate angle between two path lines on Google map. I have the lat-long coordinates of the end points of the lines. Please suggest If there is other information I can use to do this that is available from Google maps. If the distances are small you can use this method. The accuracy reduces with large distances and the further you move from the equator. First find bearings with computeHeading() computeHeading(from:LatLng, to:LatLng) .Returns the heading from one LatLng to another LatLng. Headings are expressed in degrees clockwise from North within the range [-180,180). function

I need to re-direct customers from Germany to a custom page if they try to access a product page and I've started to put something together, but I don't know how to finish it. Here's what I got: add_action( 'do not know which hook to use', 'geo_origin_redirect' ); function geo_origin_redirect() { $location = WC_Geolocation::geolocate_ip(); $country = $location['country']; $product_ids = array( 10, 20, 30 ); $product_categories = array( 'makeup' ); $redirection = false; // what to do here to make it check the product? if( in_array( $???->get_product_id(), $product_ids ) || has_term( $product

I'm using Flask in order to retrieve a coordinate value generated with javascript . Flask code: from flask import Flask, request, session, g, redirect, url_for, abort, \ render_template, flash, jsonify @app.route('/geo', methods= ['GET', 'POST']) def geo(): return render_template('geo.html') @app.route('/postmethod', methods = ['GET', 'POST']) def get_post_location(): where = request.form['location'] return where Console logs: XHR finished loading: POST "http://127.0.0.1:5000/postmethod".
