[OpenLayers-Users] Draw a line knowing its length in meters e it's angle

[mail.roliveira at gmail.com]

Thanks, I will have a look.




The move(x, y) method of OpenLayers.Geometry.Point may be helpful. But I don't understand the x, y arguments... What are the units of those values?


this could help if I move a clone of pointA.

Maybe look into the JSTS?

How do I draw a line, starting from a known point, and knowing only it's length in meters and it's angle?



Suppose I have a point at:


PointA:

lat: -22.29417905166, lon: 19.022827148438
(EPSG:4326)


Now I want to draw a line 500 meters long with an angle of 15 degrees (0 degrees is an horizontal line).



OpenLayers.Geometry.LineString allows to draw only a point from two points...


Any ideas?
