I have some .map OZI calibrated maps. From those .map, I can get some calibration points (x y in the jpeg picture + lon lat in WGS84). MMPXY,1,142,142 MMPXY,2,5217,142 MMPXY,3,5217,3422 MMPXY,4,142,3422 MMPLL,1, -0.269639, 39.626293 MMPLL,2, -0.186306, 39.626293 MMPLL,3, -0.186306, 39.584626 MMPLL,4, -0.269639, 39.584626 With ...
I am trying to design my first Android application with the use of GPS. As of right now, I have a drawable button that when clicked, alerts a Toast message of the longitude and latitude. I have tried to use the telnet localhost 5554 and then geo fix #number #number to feed in values but no results display just 0 0. I have also tried DDMS...
Hi All, I have a GPS device connected to my system which is having Windows Vista, I wanted to read the NMEA sentences from GPS device and print on screen. How I will come to know, on which port the GPS device has been connected, as there can be other devices also connected on various com ports. I am developing the application in c++,...
I thought I have read somewhere that the accuracy of Android's GPS is about 10cm? Can anyone verify or correct this? Reason being is that my application I am trying to develop keeps track of locations an user has visited and it would help me out tremendously to know the margin of error I can expect? ...
I have noticed with testing GPS locations, a value such as -123 might come up on Android as -123.83333336... is there anyway to format incoming GPS locations, such as within 2 decimal points? This way I can store values like -123.83 opposed to longer numeric values. I have checked out DecimalFormat and NumberFormat, these are strings and...
Possibly duplicate of calculate distance between 2 gps coordinates Hi, I've got a GPS location of a place. Coordinates: 33°58'9"S 18°35'51"E but inside there is another GPS location: Coordinates: 33°58'12"S 18°35'51"E I want to check that if the person is in any area in the first coordinates (33°58'9"S 18°35'51"E) it must be ...
Hi, How can I parse GPS which is string coordinates (like 33°58'9"S 18°35'51"E) to degrees e.g. double types to be used for calculating the distance between to GPS coordinates. C# programming language, the user will enter the GPS coordinates as a string (samples above). ...
I have an app at the moment which shows various pins on a map. I've tried setting mapView.showsUserLocation = YES; to show the user's current pos, however this crashed my app ("Program received signal: SIGABRT") with the following error message: Mon Oct 19 12:31:27 unknown Hull Ads[3111] <Error>: *** -[MKUserLocation counter]: unrecogni...
Are there any full featured GPS applications available with source for the iPhone, preferably that use Open Street Map to get data? None of the current offerings work very well with Voiceover on the iPhone, but it'd be a lot easier to modify an existing app to work with Voiceover then write one from scratch. ...
Hi Everybody! I have a large Oracle database ( 720,000 records aprox) where each record has its own geographic coordinates (lat & lng) and i need to select just the records that are in a specific distance from a point ( inside a specific radius). Currently i've implemented a distance function (based on haversine) that i've found in a...
Hello I am curious how hard it would it be to detect current coordinates by mobile phone? I am planning to write a mobile application which will focus on phones that can run java (ie Samsung Omina) and it will be based on the location of the user so I can do some Google map action using the coords. Using GPS sounds like an idea, howev...
I need to display a custom icon and two hyperlinks in model pop up on Blackberry map. How can I do this? ...
I'm looking into purchasing the new Samsung Intrepid Windows Mobile 6.5 device. Before I plunk down the cash, I'm investigating the available APIs and support resources. I have one question I want answered. It's one question but it's a big one for me. Can I access the GPS coordinates of the device? Does this phone have a location API? I'...
Basically I'm wanting to create a GPS system for my car that works offline, but I'm just a hobbyist and doing this for fun, so I don't have a ton of money to invest. Are there open databases I can use for the data (roads, speed limits, etc), or is it just impossible to do? ...
So I'm trying to sample the gps coordinates just once in an application. I don't want to create a LocationListener object to constantly get gps updates. I want to wait until receiving the coordinates, and then proceed on to another task. Here is a code snippet LocationManager lm = (LocationManager)act.getSystemService(Context.LOCATIO...
Does anyone know of a library or algorithm (whether freely or commercially available) to compute viewable GPS satellites for a particular location? Even better, does anyone know of a library or algorithm to compute the footprints of GPS satellites given almanac or ephemeris data? Thanks, Jacob ...
This is a question-loaded post from someone who is just getting started with BB development. Any guidance is much appreciated. How are map based BlackBerry apps such as Yelp and Google Map implemented? As with the web based version. Yelp for the BB allows you to search for restaurants & etc. based on on the current or specified loca...
Does anyone know how to turn off iPhone's GPS programmatically? Once I use the CLLocationManager to get three reads of my location I stop updating location as in the code below: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { if((ne...
Android 2.0 has turn-by-turn directions, however, I do not yet see an API exposed for this in the 2.0 SDK. Are there any documented plans to expose an API for calling into the new turn-by-turn features? ...
