Hi there! I have a really basic question here. I have a point and from there I would like to get another 2 points to create a triangle. That's pretty basic trigonometry stuff.
The only issue, is that I'm trying to get it to work with the lat/lon coordinate system. What I want is given a point A (10,10) and a radius in meters, for example 30 meters I want to find the pair of points that are 30 degrees up and 30 degrees down. Normally I would do is x1 = x+r*cos(30) problem is while x is in a decimal lat, r is in meters. I'm converting 1meter in decimal as follow: value = 1d/(30.9)*Math.cos(Math.toRadians(Math.abs(latitude))); return value/3600; But when I add the markers on the map they are way closer than supposed to be. I'm using OSM and first I create the LonLat on decimal format (all points) and then I transform them. Any ideas on what am i missing here?
