If working with vector point data and co-ordinates in meters, then using
v.buffer with (e.g.) a major axis of 25000 and minor axis of 10000
would create ellipsoid buffers around the point data. If you used
v.buffer with only a major axis of 25000, this would create a circle buffer.<br><br><br><div class="gmail_quote">On Fri, Jun 17, 2011 at 2:49 AM, Kurt Menke <span dir="ltr"><<a href="mailto:kurt@birdseyeviewgis.com">kurt@birdseyeviewgis.com</a>></span> wrote:<br>
