I am getting GPS data on my window
Actual GPS DATA is stored in these 2 variables
Code:
float landlong= 77.384547E //Realtime Longtitude
float landlat = 12.583857N   //RealTime Latitude
But it seems the lat & long which iam getting from GPS is not coming inside window, its out of window .I checked x & y cordinates it is
Code:
xPos = 1415.7537		
yPos = -167.81079
the width & height of my window is
Code:
m_WndWidth=1099
m_WndHeight=673
The formula which iam using to calclulate x & y cordinates is

Code:
xPos = (landlong - m_fMinLon) * (m_WndWidth / (m_fMaxLon - m_fMinLon)) ;
yPos = (landlat - m_fMinLat)  * (m_WndHeight / (m_fMaxLat - m_fMinLat)) ;
Code:
BOTTOM RIGHT CORDINATES
m_fMaxLat = 12.581369; //MAX lat value	
m_fMaxLon = 77.383798;// Max long value

TOP LEFT CORDINATES
m_fMinLat = 12.583361;//Min lat value	
m_fMinLon = 77.381506;//min long value
Does anyone has the proper formula to calculate X & Y cordinates

Thanks in advance
