[postgis-users] Get point certain degree of another point

[Mike Toews]

Apply the same COGO trigonometry as before[1]:

import math

class Point:
    def __init__(self, x, y):
        self.x=x; self.y=y

def TranslateBearingDistance(pt, rad, dist):
    return Point(pt.x + dist*math.cos(rad), pt.y + dist*math.sin(rad))

pt0 = Point(100, 100)

# 12 units away at 30 degrees CCW from x-axis
pt1 = TranslateBearingDistance(pt0, 30*2*math.pi/360, 12)

print pt1.x, pt1.y
# 110.392304845 106.0
