I'm looking for ways to programmatically convert my GPS logs to images and would like to do this in Ruby... if that's an acceptable tool. I have no GIS background whatsoever but as a programmer i think it's an interesting problem to look at. Here is what I have come up with so far. First you'll need some kind of graphing library. I went...

I have a SQL database where I store longitude and latitude from an iPhone application. I need to query all the records starting from a given location to the other far most location.

Hey guys, I've a really strange problem, I'm getting location updates with a GPS Listener, everything works fine. I also watch this listener with a timeout, if the timeout gets exeeded, it stops the thread, removesLocation updates everything works... BUT, if there's no Internet Connection available, an exeption gets called, it should ...
Can GPS on a phone, such as iPhone or Android determine your Z coordinates ? I know it certainly has to be able to determine X and Y, well longitude, latitude that is, but what about the Z coordinates ? Can it determine your height, and can I obtain height relative to ground ? ...
I'm writing a toy car-navigation app for Android, mostly to learn the Android SDK. While testing my application, it worked fine for a few hours. Then, suddenly, it reported my position as being in a town 100km south of my real position, travelling at 300km/h. I was in fact travelling at approximately 120km/h. I changed application to G...
I can't believe this code doesn't work - because I've written several other apps that use location services like this... but apparently I've missed something and I can't figure out what it is. Any help would be greatly appreciated... My output log check for the tag "GPS" just shows the following: 07-19 05:50:34.567: DEBUG/GPS(4883): L...
hi I have used LastKnownLoaction at the start-up Activity of my app to get the location ,if it returns null then i register for a Location Listener for both gps and network providers.After requesting for Listener to listen for any location change i switch over to main Activity page using startActivity.Further in the startup Actyivity's...
I added a gps status listener to my location manager in order see when I get the first fix. When I receive the GPS_EVENT_FIRST_FIX I then loop through all the satellites, but why is none of them used in the fix? (usedInFix()). My log says 'false' for all satellites? final class GpsStatusListener implements GpsStatus.Listener { pub...
I'm new to development for Android and I am curious if it is even possible to request and accurate location of another android device? For example, If I wanted to find where a friend is located and show it on my device in google maps. ...
Can someone tell me, what is the best way to deal with situations when there is no GPS signal or from some reason fix cannot be acquired? The thing is that I thought that it would be sufficient just to use onStatusChanged method from LocationListener, but when there is no GPS signal it never calls this method. Why is that? Thanks ...

I need to develop a web app. (PHP) 100% for mobile phones and need to get the information from the mobile phone GPS, in order to get the user's current position. My question is, what should I do?

I have managed to get GPS tag from a jpeg file using the GOOGLE-EXIF(http://code.google.com/p/iphone-exif/) But, when I test my program on a device with OS 4.0, I found all the camera roll's photos are stored in a .THM format. I cannot get the GPS tag from those files. How can I get all the original JPG files, if there is not a origina...
Hi, I create a proximity alert in this way private void setProximityAlert(float radius, double lat, double lng, String place) { long expiration = -1; LocationManager locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Intent intent = new Intent(TREASURE_PROXIMITY_ALERT); intent.putExtra("lat", ...
I have read up on GPS Real time tracking and found out several things about it, mostly requiring PHP, zope and a database to store the incoming data. Some other methods uses ajax with relations to PHP. As regards to my question, is it possible to do so with just html and JS, using markers or anything else to populate the Google Map whe...

I looked for the answer but didn't find one - my question(s) follow: I wrote code that works with the emulator (I send local coords vis DDMS). The code also works on the device BUT, only after running Google Map. I'm guessing there's something missing in either the manifest or in the code but I don't know what it is and I could use so...
I have a GPS class which i obviously use to acquire the latitudes and longitudes. The UpdateData() is called when the gps state or location is changed. So i make sure that both the Latitude and Longitude is valid and then i make the DataReady bool equal to true. So i use this code in a fairly n00b fashion where i use a Timer (Windows ...
I have successfully been getting GPS data through the registerLocationListener() and onLocationChanged() methods. The only problem with this is that the speed reading of my app freezes if there is no more GPS data (e.g. when I go indoors, enter a tunnel, etc). The behavior I want for my app is that the user is somehow notified that the s...
