geolocation - getting the location and speed via mobile platforms -

-

is there possibility of getting location of user, moving direction, , speed via mobile platforms(client side programming j2me) ? if there availability in platform please let me know platform , please give me study links study it?

regards, rangana

i'm not sure if there api this, because don't think information (velocity) available.

you can still figure out though, , work on cell phones allow access "current location".

  1. ping phone it's current location every n seconds (10,20,30 seconds, etc...)
  2. log location of phone @ every ping (lat,long)
  3. determine distance traveled ping-to-ping. may need use vector resolution (http://www.physicsclassroom.com/class/vectors/u3l1e.cfm)

for example, if phone moves 1000 meters on course of 30 second ping, means: 1000 meters / 30 seconds = 33.333 m/s

doing this, can determine acceleration, etc... not give instantaneous velocity or acceleration, instead average velocity , average acceleration.
