Is a LINESTRING always a straight line in postgis? Or can there be a curvature? I didn't get that from the documentation.<br><br><div class="gmail_quote">On Wed, Mar 14, 2012 at 10:04 AM, Ed Linde <span dir="ltr"><<a href="mailto:edolinde@gmail.com">edolinde@gmail.com</a>></span> wrote:<br>

Is it possible to achieve the same effect using GDAL's C++ API? I ask because I have a very large LIDAR 3-D data set<br>
