Masalah
Saya ingin tahu bagaimana mendapatkan jarak dan arah antara 2 titik GPS . Saya telah meneliti formula haversine. Seseorang memberi tahu saya bahwa saya juga dapat menemukan arah menggunakan data yang sama.
Edit
Semuanya berfungsi dengan baik tetapi bantalannya belum berfungsi dengan baik. Output bearing negatif tetapi harus antara 0 - 360 derajat. Data yang ditetapkan harus membuat bantalan horizontal 96.02166666666666
dan:
Start point: 53.32055555555556 , -1.7297222222222221
Bearing: 96.02166666666666
Distance: 2 km
Destination point: 53.31861111111111, -1.6997222222222223
Final bearing: 96.04555555555555
Ini kode baru saya:
from math import *
Aaltitude = 2000
Oppsite = 20000
lat1 = 53.32055555555556
lat2 = 53.31861111111111
lon1 = -1.7297222222222221
lon2 = -1.6997222222222223
lon1, lat1, lon2, lat2 = map(radians, [lon1, lat1, lon2, lat2])
dlon = lon2 - lon1
dlat = lat2 - lat1
a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
c = 2 * atan2(sqrt(a), sqrt(1-a))
Base = 6371 * c
Bearing =atan2(cos(lat1)*sin(lat2)-sin(lat1)*cos(lat2)*cos(lon2-lon1), sin(lon2-lon1)*cos(lat2))
Bearing = degrees(Bearing)
print ""
print ""
print "--------------------"
print "Horizontal Distance:"
print Base
print "--------------------"
print "Bearing:"
print Bearing
print "--------------------"
Base2 = Base * 1000
distance = Base * 2 + Oppsite * 2 / 2
Caltitude = Oppsite - Aaltitude
a = Oppsite/Base
b = atan(a)
c = degrees(b)
distance = distance / 1000
print "The degree of vertical angle is:"
print c
print "--------------------"
print "The distance between the Balloon GPS and the Antenna GPS is:"
print distance
print "--------------------"
atan2(sqrt(a), sqrt(1-a))
sama denganasin(sqrt(a))
