Mathematical Problem

[JessNil]

Guys,

I need your help....

Let's say I have a point which is located at 14° 30' 31N 121° 1' 11E, we will name this point as A. I have another point located at 15° 11' 10N 120° 33' 37E, will name this as B. What is the formula to know if B is within 300Meters of A?

Is it possible to convert this points into Meters?

Please and Thanks for any help I can get ! ...

Let's say...you need to make a third point of reference. say point C;

With this way; you complete a triangle.

then use the phytagorean theorem where a^2 + b^2 = c^2
(^2 = squared)

Lets not go into the details... You're scaring me

Hope this helps !

Ya that should be sufficient, but I've been taught to use spherical coordinates to get the most accurate results... but even I don't really remember that now!
In any case, since 1 minute (or 1/60 degree) = 1 nautical mile, once you know how many degrees those two points are apart, you can convert to metres using the conversion ratio of 1 NM = 1852 metres.
