geolocation

I am looking for a way to get the user's current location (city) based on is IP address using the Google Maps APIs. Something similar to http://freegeoip.net/json but only using the Google Maps APIs. Is this possible? Peter Knego Google already appends location data to all requests coming into GAE (see Request Header documentation for go , java , php and python ). You should be interested X-AppEngine-Country , X-AppEngine-Region , X-AppEngine-City and X-AppEngine-CityLatLong headers. An example looks like this: X-AppEngine-Country:US X-AppEngine-Region:ca X-AppEngine-City:norwalk X-AppEngine

I want to present my users with a text box wherein they can type in their address. As they type their address, I want to provide the users with suggestions/predictions of what address they are trying to type. I'm also concerned about the relevance of this address (e.g. that the address is not an address halfway across the world). Is this possible? I'm using jQuery. You can use Google Places API to have an autocomplete for address. When address is selected, address_components field contains structured address data (e.g. street, city, country) and could be easily converted into separate fields.

MongoDB has a very nice Geospatial Indexing feature. How can I use it in Rails with Mongoid? You can define geo indexes like this in mongoid class Item include Mongoid::Document field :loc, :type => Array index( [ [:loc, Mongo::GEO2D] ], background: true ) end And for queries $near command (without maxDistance) location = [80.24958300000003, 13.060422] items = Item.where(:loc => {"$near" => location}) $near command (with maxDistance) distance = 10 #km location = [80.24958300000003, 13.060422] items = Item.where(:loc => {"$near" => location , '$maxDistance' => distance.fdiv(111.12)}) Convert

Is it possible to make use of geo-based push notifications on iOS when the application is killed (not in the background)? I am interested in building an app, where the user will choose a position on a map, and then if he/she for example is close to that area a local geo-based push notification would be triggered. However is this "idea" even possible? Can the GPS run and compare coordinates when the app is killed and run and notify the user when is in place? Is there a tutorial/article/more information of any kind on the subject that i could read? Most of the information I read online were more

i am trying to submit user registration form in android with current location. I am new to android and java development. when i try to access myLat and myLan of the onLocationChanged method in my name value pairs code , it is unable to find both the variables. How can i access both the variables in my name value pair code. package com.imran; import java.io.IOException; import java.util.ArrayList; import java.util.List; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient;

Currently, I'm using parts of the GeoFirebase library along with Firestore to allow for geoquerying. When I set the geohash of a post, I do it as such if let geoHash = GFGeoHash(location: location.coordinate).geoHashValue { However, to make the geohash querying less specific, I'm planning on truncating part of the geohash when I query; currently, the query looks similar to this var geoQuerySpecific = GFGeoHashQuery() let geoQueryHash = GFGeoHashQuery.queries(forLocation: (lastLocation?.coordinate)!, radius: (30)) as! Set<GFGeoHashQuery> for query in geoQueryHash { geoQuerySpecific = query

I am trying to build a rather complicated query in SQL, and being a beginner i would immensely appreciate some help to build it. I am trying to achieve the following: 1/ Calculate the distance between a postcode in the target_postcodes table - say E1 1AA - and all the postcodes in the the population_postcodes table using Cartesian latitude and longitude coordinates using Pythagoras: SQRT( POW(MY_Y_AXIS - Y_AXIS, 2) + POW(MY_X_AXIS-X_AXIS, 2) ) 2/ Create a new column with those distance values, not sure how to do that step 2-bis/ Sort postcodes in the population_postcodes by the distance value
