Description

This application will allow guests to reportyour traveling everywhere!
You do not need neither GSM or GPS or WiFi!

Download the available maps of localities (caves, quarries, etc...)
Or use Google maps cards to create new maps (screenshots)
Share your maps and navigate!


=============================================================
How it works ?
=============================================================
1) Import or download the map of a place known since theapplication
2) Select your starting point on the map - Navigation starts
3) Walk with your phone well in hand
4) Your course is carried live on your map


Technically this is a simple diagram of the operation:

One step is detected ....
> Length of not -> Converted into pixels according to thescale of the map & the zoom level
> Compass -> Angle value compared to North (rectified withthe magnetic declination) and converted to radians
>> Trigonometric calculation and deferral of a new point onthe map in terms of:
---> From the current position
---> From the angle in radians and stride length
>> Report on the map
>>> Waiting for next step

=============================================================
The precision :
=============================================================
One can easily arrive at a 95% accuracy over a distance of100m.
That is the position shifted to a well-regulated application after100m path will be refused only 5m from the actual position!

To improve accuracy:
> Place checkpoints to restart navigating a pointidentified
> Keep your device well always face your hand path
> Check the pedometer is set




=============================================================
Warning :
=============================================================
The use of this application does not relieve you of the law.
Underground, follow the basic rules such as not leave your goup inareas you do not know, always have a flashlight, compass and foodon you. And leave the place clean!
