CO-ORDINATES CALCULATION
Distance
and Bearing
If you have
two points Coordinates how can we calculates Distance and bearing
1. N1 = 1600 N2 = 1900
2. E1 = 1500 E2 =
2200
FOURMULA NO 1
DISTANCE = Poll(N1-N2,E1-E2)
Bearing = tan-1 √diff of N1and N2÷diff of E1 and E2
Now we
will Apply
Poll(1600-1900,1500-2200)=761.577
distance
Bearing = tan-1 √1500-2200÷1600-1900
Bearing =66 degree 48
minutes 07 sec
FOURMULA NO 2
DISTANCE= √latitude²+depature²
Bearing = tan-1√depature÷latitude
What is Latitude and Departure
lat² is diff of NORTHINGS ( N1 – N2 )
Dep² is diff of EASTINGS (E1 - E2 )
If you Have One Point Co-ordinate How
Can We Calculate the Second Point Co-ordinates
1. N1 = 1600 E1
= 1500
Bearing = 66 degree 48 minutes
07 sec
Distance = 20m
1. N2=?
2. E2=?
For N2
N2 = Cos(Bearing)˟Distance+N1
N2= Cos (= 66 degree 48
minutes 07 sec)˟20+1600
N2 = 1607.87
For E2
E2 = Sin(Bearing)˟Distance+E1
E2 = Sin(= 66̊ 48̊̊ 07̊̊̊)˟20+1500
E2 = 1518.38
