How to plot a GPS location on an image being used as a map?

由 笑着哭i 提交于 2019-12-04 19:41:39
I have images of malls that I need to use as maps for an app I am making. I have the GPS lat/long of the bottom corners of the map and I figured out the distance from the bottom GPS coordinates to what would be the top of the map image. How ever these are not straight up and down linear maps meaning I can't just plot my lat and long all nice and neat. I've tried using various formulas and I'm so close but I can't plot the top lat and long of the top left and right of the map. So far this is what I have: double distanceFromLeftToRightGPS = bottomLeft.distanceTo(bottomRight); double

Hey guys, I'm having trouble trying to find the user's longitude and location as I run my program and set the telnet command for geo fix for the mock location. While the emulator is running, I set the mock coordinates only for the emulator to become unresponsive and have my program fail in detecting the input coordinates. import android.app.Activity; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.location.LocationProvider; import android.os.Bundle; import android.widget.TextView

Android FusedLocationProviderApi: Incoming intent has no LocationResult or LocationAvailability

由 不想你离开。 提交于 2019-12-04 18:29:52
问题 I am trying to subscribe to location updates via Google's FusedLocationProviderApi. I want to receive updates in the background, so that I will receive updates even if the app is killed. Following the online documentation as best as I can, I've written the following code. Note: this is being done in an intent service, not on the UI thread, which is why I'm using blocking connect/result methods. private void startLocationServices(String deviceId, int pollingInterval) { Log.i(TAG, "Starting

I am working on an iOS app with codename one . I want to get the current location and send it by SMS.

Return Nearest Place available to Users location using Latitude-Longitude?

由 ↘锁芯ラ 提交于 2019-12-04 18:05:23
I want to implement Nearest Place available to User algorithm in Java or MySQL. I have Stations table in MySQL database which has around 100K records of Stations with Latitude and Longitude . If User gives his latitude and longitude as x and y, then I want to return nearest stations available from User's location. So please suggest me any algorithm available in Java or MySQL . I tried with the following query, but it seems slower in performance - SELECT *,3956*2*ASIN(SQRT(POWER(SIN((user_lat-abs(st.station_lat))*pi()/180/2 ), 2) + COS(user_lat*pi()/180)*COS(abs(st.station_lat) *pi()/180)*POWER

Why is geosearching/location based searches returning zero results?

由 徘徊边缘 提交于 2019-12-04 17:48:29
I am trying to use app engine's search API to search locations: https://developers.google.com/appengine/docs/python/search/overview#Performing_Location-Based_Searches The problem is no matter what I do, I get zero results. I set the search lat/lng as the the exact point on a document's GeoPoint property and it still returns zero. I know the regular search is working because if I change the query to be a regular full-text search, it works. Here is an example of my data (this is actually from the example app here: http://www.youtube.com/watch?v=cE6gb5pqr1k ) Full Text Search > stores1 Document
