问题 OK, so I already have the answer to this question but it took me a long time to reach it so I thought I would share it, particularly since someone asked me but under an unrelated question I created a Phonegap-based navigation app for guided walks that tracks the user's location around a predefined route using GPS. My routes have triggers placed at specific geo-locations around the route which give instructions to the user based on their current location. The problem is that GPS is not super

问题 I have upgraded the geolocation plugin in cordova 3.5 to fix the issue in iOS 8 by following this post. http://shazronatadobe.wordpress.com/2014/09/18/cordova-ios-and-ios-8/ After running the app in iOS8 simulator, I am getting the notification 'Allow "MyApp" to access your location while you use the app?' But it still shows the error locationManager::didFailWithError (null) after allowing the location service to use the app. I have tried to close the simulator and run it again and again.

I want to find an angle between two known geolocations.Basically what I want is, I want to direct an arrow whose tail point is at my current location and arrow head is pointing towards a fixed geolocation. So I am thinking if somehow, I am able to get an angle between these two geolocations then propably i will be able to do the same. Do you guys have some suggestions to do it in a better manner. Any help would be appreciated. Hyperboreus Refer to this, there are several approaches explained. How do I calculate the Azimuth (angle to north) between two WGS84 coordinates I wanted to achieve the

How to get barometric altitude in Android?

由 ╄→гoц情女王★ 提交于 2019-12-01 08:42:35
What are the data needed for calculating barometric altitude? How do I get them and then calculate the altitude? Also how accurate is the barometric compared to GPS altitude? I tried GPS but after searching hours in the web I cannot find a suitable Geoid library. Please correct me if I got any concept long. You need to use the pressure sensor to measure the pressure then use the SensorManager.getAltitude(float, float) call to convert the measures pressure along with a reference sea level pressure to get the altitude. The tricky bit is what to use as the reference pressure. This will change

Geo Location API and finding user within a radius

由 半世苍凉 提交于 2019-12-01 08:14:43
问题 I have a Java application and I would like to find out the location of a visitor. The API would give me a the zip code of visitor and then based on that zip code, I will find fire a query and get users in my application within 25/50 mile radius. Alternatively visitor can type in the zip code of their interest and application should return users withing x mile of radius. For the users who are registered in the system, we have only their zip code. I have looked around some options but not found

Android service with locationListener callbacks

由 我与影子孤独终老i 提交于 2019-12-01 07:39:45
问题 I have an android application. Based on the current geo location of user, I want to fetch some remote data in background and store it. My implementation is: At specific interval a alarm fires up my service. Service uses an anonymous class to query current location and registers a locationListener callback. On call of onLocationChanged() I initiate the remote data fetch from server. However once my service is done registering the location listener using anonymos class, it returns as expected;

Is there any browser (Chrome, Firefox) plugin that allows to simulate geo location?

由 [亡魂溺海] 提交于 2019-12-01 06:29:35
I need to test web application that extensively uses geo location api (getCurrentPosition, watchPosition). Is there any browser (Chrome, Firefox) plugin that allows to simulate geo location? If I understood the question correctly and you're asking for a way to fake geolocation responses for your web app, you might be able to do this in Firefox by overriding the geo.wifi.uri in the prefs, like Firefox's unit tests do.
