[OpenLayers-Users] Buffers in kilometer

[Robert Sanson]

Your map is in geographic coordinates (lat/long). Conversion of degrees to meters is complex as it varies depending on latitude.

Take a look at the function OpenLayers.Util.destinationVincenty

You might be able to write a function that takes your vector points and then generates the coordinates of the buffer around them

Another option would be to project your map features that you want buffered into a metric projection eg. Spherical Mercator, then buffer them in m, then reproject them back to 4326 and add them to your vector layer.

regards,

Robert
