I am wanting to use curves (arcs) for representing roadways.<br>
I am having trouble finding documentation on curves.<br>
<br>
My googling brings up articles like:<br>
<br>
<a href="https://gip.itc.nl/default/node/75" rel="noreferrer" target="_blank">https://gip.itc.nl/default/node/75</a><br>
<br>
and others dated around 2012.<br>
<br>
Can someone direct me to some current tutorials or documentation on<br>
using curves in PostGIS?<br>
<br>
I am particularly interested in calculating radii, but would appreciate<br>
a general article on curves..<br>
<br>
Many thanks,<br>
H<br>
