I have a set of points starting from (0,0,0) charting a path taken by a vehicle in 3D with each point being the distance traveled in its respective dimension. I need to do 2 things Let (0,0,0) denote a latitude and longitude. How do I convert my set of points in 3D to it's equivalent in latitude and longitude? Plot it frame-by-frame (w...
I'm thinking about building an iphone app that would use the GPS feature to track where someone is and for how long. I realize I could probably get the current location from the iphone from a website but the only way I'm familiar with is using ajax calls, etc (Sorry if this is a rather newbie concept) but I fear that would bog down my s...
Does anyone know the most efficient representation for lat/long coordinates? Accuracy level should be enough for consumer GPS devices. Most implementations seem to use double for each unit, but I'm suspicious that a float or fixed point format should be sufficient. I'd be curious to hear from anyone who has tried to compress and or stor...
When you obtain the lat/long values from a GPS enabled blackberry device, how do you send those values to a server via a url? By the way, I'm trying to do this in Javascript. "window.location.href=..." works fine on the iphone. I was thinking something like this would work but it doesn't seem to: function locationCB() { ...
I'm writing a location based application, and I currently have an iPhone first gen, but I'm wondering how long it takes for an iPhone 3G or 3Gs to determine its location using the GPS chip ? As far as I understand it, locationManager:didUpdateToLocation:fromLocation: may keep getting called with more and more accurate location informati...
It's well known that UIImagePickerController doesn't return the metadata of the photo after selection. However, a couple of apps in the app store (Mobile Fotos, PixelPipe) seem to be able to read the original files and the EXIF data stored within them, enabling the app to extract the geodata from the selected photo. They seem to do this...
Is it possible to get GPS information in a mobile device through APIs without having any GPRS connectivity? Edited Yes, for example on the Java ME platform or Apple iPhone ...
I have a Mio P550 device, which has a GPS included. I try to use SerialPort to get NMEA sentences, by simply use SerialPort.Read(). Data is returned in some weird encoding. GPS should return NMEA sentences in ASCII, but it doesn't. Here is my code for reading: dataLength = this.serialPort.Read(buffor, 0, Gps.BUFFOR_LENGT...
I wrote simple NMEA parser and I'm reading latitude and longitude from GPS. Values readed by my parser are very scattered comparing to some GPS commercial library I'm using. Values readed from this library are very smooth. What algorithms I should use to correct readed position from gps? ...
I need some help coming up with an algorithm to determine the minimum bounding rectangle around a set of lat/lon coordinates. It is OK to assume a flat earth since the coordinates will not be too far apart. Pseudocode is OK, but if someone has done this in objective-C, that would be even better. What I am trying to do is set the zoom ...
Greetings! My wife, my 9 year old, and myself all have iPhones with me.com subscriptions. One of the "killer features" (at least for me) in the 3.0 firmware was the "find my iPhone" functionality. I would like to build some sort of tool that would poll the "find my iPhone" service every once in a while, and I could build some sort of da...
Hi all, I'm developing an web application (jsp/strtus2) which requires the GPS coordinates of a place. What I want to know is, whether there are any free web services that I can get GPS coordinates of a place by passing address or zip code to the server. Thanks in advance, Nuwan ...
I've been working to iron out memory leaks in my program and I'm down to a few stragglers. The strange thing is that they're coming from when I use CoreLocation to get a gps location. The code is properly returning the location, but it's leaking all over the place: CFHTTPMessage, CFURLConnection, CFURLRequest, CFURLResponse, GeneralBloc...
The iPhone supports geolocation in mobile Safari via the following call: navigator.geolocation.getCurrentPosition( function(pos){ var lat = pos.coords.latitude; var long = pos.coords.longitude; }, function(){ /* Handler if location could not be found */ } ); I'd like to build a good list of devices that have one of...

If i have a jpeg map with size sizeX, sizeY and some calibration points on the map (X, Y, Lon, Lat) What would be the algorithm for calculating the corresponding XY point in the map with a given Longitude / Latitude pair? ...
Hi all, I have written an iPhone app that uses the iPhone's relative GPS location. I have a button in the user interface that does reverse geolocation (pulls the street name bases on the lat and long). The only problem is that the location object as retrieved by CLLocation *location = [[self locationManager] location]; is nil if th...
Can anyone tell how to use Google maps in blackberry application development instead of Blackberry map.If you have any idea about this please help me,If possible provide me a some code snippet. regards, s.kumaran. ...
After I closed my app for a while then reopen it again,my app will not update location or sometime it will take long time( about 5min) before update. How can I fix it? This is my code private LocationManager lm; private LocationListener locationListener; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedIn...
