Hi, We have started developing an application for location aware emergency service. The users can connect through computer,smart phone or even through WAP. The problem we are facing is, we don't know how to get the location of the user who is asking for service. If it is GPS enabled smart phone, it can be located though the app. I have ...
Here's my scenario: say a GPS device is in a car, how can I (e.g. a remote Silverlight client) communicate with that GPS device to track it via a map, e.g. Bing Maps? Is there a way for a GPS devices to 'push' messages to my Silverlight application or vice versa the GPS devices (maybe WP7 device) push notifications to the SL application...

Now selecting one of these cities, i want to obtain all the other cities that have a longitude / latitude in a range of 50 km from the selected city. What formula should I use? I am only interested in the mathematical formula to convert km to latidutine and...

In my company we do have critical systems that require an accurate time. As so, we have an NTP server appliance with an outdoor GPS antenna that receives the time from the GPS satellites. My questions are: How accurate is the time clock? Is it worth it to keep this way or use another external NTP (US-GOV, NASA, etc) ? Thanks, ...
Hello, I have spent sometime researching the forum and other places to resolve this but yielded nothing and I have decided to ask. I have log files containing NMEA sentences. I have stored this sentences which are in hundreds of thousands in mysql database. I have stored the longitudes and latitudes as double datatype. I want to conver...
I'm using CLLocationManager to get a location, and I need I within about 40-50 meters. I have desiredAccuracy set to nearest ten meters (also tried with best). It always comes up as 100.00. No higher, no lower. Don't have cell service on the phone, just going off GPS and WiFi. iPhone 3G. Also tried with Apple's LocateMe sample proj...
I'm writing an app for a museum tour. I'd like my app to know where the user is in the building, if the user is standing in a particular room, in front of a particular work, etc. GPS doesn't work inside. (Using WiFi positioning could work, but I know Apple doesn't use Skyhook anymore, so I don't know where I would register my base stati...
Hi everybody ! I am developing an application that use the GPS and the geolocalion. So, during the application launch, I have to be sure that the user has activated the network and GPS. If he didn't tested 2 solutions : Ask the user to activate them himself (so the application quit, and the user has to reload it) Redirect the user in...

I have some code doing this right now. It works fine with small to medium sized lists, but when I have a list of size n > 5000 then the my algorithm can take almost 1 minute on a mobile device to run. I'm basically comparing a Coordinate object in Java to a list (Vector) of Coordinate objects. Here's my basic algorithm: traverse each ...
I'm using the below code to put an overlay on my MapView. For some reason after itterating through the location data it draws the point in the same place. It seems to be happening on conversion from Location to GeoPoint to Projection: Location (lat : lon) 51.2651789188385 : -0.5398589372634888 Projection (x : y) 239 : ...
