If I have the coordinates of a point (lat lon) and the azimuth angle how can I calculate what points are at "the end' of a distance of 10 miles.
Ex. I am watching North , I know I am at a certain point ... At 10 miles apart what coordinates has that geo...

You need to also have a bearing' answer is a nice interactive site.
The result is that lat2 according to that formula can be 2 at most.

Suppose I have the following:
A region defined by minimum and maximum latitude and longitude (commonly a 'lat-long rect', though it's not actually rectangular except in certain projections). A circle, defined by a center lat/long and a radius How can ...

I got of the sphere, e.g.:
"rectangle": min long = -90deg, max long = +90deg, min lat = +70deg, max lat = +80deg
circle: center ....
This method is used to calculate the distance between to lat and lon points.
For your sphere.

So given X=1280532, Y=211374
Lat = 47 + ( 211374 / 6096 / 60 ) = 47.58 Lon = -117....
This is roughly the position of Spokane WA.

Has anyone got a formula that:
given a lat/long starting point plus a distance and bearing
will output the new lat/long position?
I found this but it doesnt seem to work right

The altitude wasnt well defined in the formula i found.
Variable in the atan2
calculation? I suspect it should be d_lat.

I am familiar with the formula to calculate the Great Circle Distance between two points.
i.e.
<?php $theta = $lon1 - $lon2; $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)); $dist...

Lon1), a bearing in radians(θ), a distance travelled (d), and a radius of the earth (R), you can work start point (lat1, lon1), a bearing in radians(θ), a distance travelled (d), and a radius.

How do you draw the curve representing the shortest distance between 2 points on a flat map of the Earth?
Of course, the line would not be a straight line because the Earth is curved. (For example, the shortest distance between 2 airports is curved.)

Here we find points (lat,lon) a given fraction of the distance (d) between them*sin(lat2) lat=atan2(z,sqrt(x^2+y^2)) lon=atan2(y,x)
Your question is totally dependend formula, which is less subject....
Latitude or longitude.
