I thought I would published my solution here, for all the ppl who are lazy<br>
like me, and google for a solution before posting...<br>
Dis problem is reduced to finding the InCirce of a polygon, which is<br>
slightly different from the well-known geometry problem: largest empty<br>
circle.<br>
<br>
<a href="http://www.personal.kent.edu/%7Ermuhamma/Compgeometry/MyCG/CG-Applets/LgEmptyCircle/lccli.htm" target="_blank">http://www.personal.kent.edu/~rmuhamma/Compgeometry/MyCG/CG-Applets/LgEmptyCircle/lccli.htm</a><br>
<br>
In the &quot;largest empty circle&quot; we calculate the Voronoi Diagrams and test<br>
each of its vertexes inside the convex-hull as a candidate for the center.<br>
It all comes down<br>
to a max-min optimization of the radius: the largest radius, that does not<br>
contain any points inside (and therefore, the circle is &quot;empty&quot;).<br>
The Largest inscribed circle, is very similar except that here we look for a<br>
circle that does not contain the *actual* polygon (rather than just its<br>
vertexes).<br>
The distance we wont to test here is the (minimum) distance of the candidate<br>
centre to the polygon.<br>
I struggled a little bit here to measure a distance from polygon to a point<br>
that is located inside it, and ended up having to decompose the polygon to<br>
its boundary<br>
to get it done (Im using OGR)!<br>
Here is the result:<br>
<br>
<a href="http://ladybug.no-ip.org/files/inCircle.png" target="_blank">http://ladybug.no-ip.org/files/inCircle.png</a><br>
<br>
Just as a final note: there are plenty (exact) implementations of the<br>
incircle (or apotheom) of a triangle or a regular polygon, but it becomes a<br>
bit complicated when we are dealing<br>
with irregular geometries, which is my case... (and prob everyone else<br>
workin in GIS)<br>

&gt; Hi Jo,<br>
&gt;<br>
&gt; You mean you want to know about &quot;Incircle of an irregular polygon&quot;?<br>
&gt;<br>
&gt; I don&#39;t know that GEOS(or JTS) had already implement it,<br>
&gt; but if not, you might google the word above. (and I hope GEOS(or JTS)<br>
&gt; implement it)<br>
&gt;<br>
&gt; The following site is written in Japanese, but the images may be helpful.<br>

&gt; &gt; Hi,First of all, I apologize if this post is unrelated to the scope of<br>
&gt; the<br>
&gt; &gt; mailing list (I hope not).<br>
&gt; &gt; I have to find an algorithm to draw the maximum enclosed circle in a<br>
&gt; &gt; polygon, which is slightly different from the &quot;well-known&quot; geometry<br>
&gt; problem:<br>
&gt; &gt; &quot;maximum empty circle&quot;; in this case, not only all the vertices need to<br>
&gt; be<br>
&gt; &gt; outside the circle but also the entire perimeter of the polygon must<br>
&gt; *not*<br>
&gt; &gt; be inside the circle.<br>
&gt; &gt; I can get the center of the polygon using Voronoi Diagrams: anybody has<br>
&gt; any<br>
&gt; &gt; suggestions or recomendations of how to calculate its radius?<br>
&gt; &gt; Also, I would like to avoid as much as possible iterative processes (as<br>
&gt; &gt; they can be slow when dealing with a high number of polygons, that have<br>
&gt; &gt; complex frontiers)...<br>
&gt; &gt; It would be really appreciated any ideas on this, or even references to<br>
&gt; &gt; libraries that could help me... Im not finding a lot of stuff about this<br>
&gt; on<br>
&gt; &gt; the web :-/ Im using C/C++ but all ideas are welcome, really...<br>
&gt; &gt;<br>
&gt; &gt; Thanks in advance for your time!<br>
&gt; &gt;                                         cheers,<br>

&gt; Hi Allegri,<br>
&gt;<br>
&gt; I encountered the same problem today.<br>
&gt; (I am using gcc-3.4.5, referring to<br>
&gt; <a href="http://trac.osgeo.org/postgis/wiki/UsersWikiWinCompile" target="_blank">http://trac.osgeo.org/postgis/wiki/UsersWikiWinCompile</a>)<br>
&gt;<br>
&gt; The cause seems to be the latest MinGW bug, and Mark has already report<br>
&gt; MinGW tracker.<br>
&gt;<br>
&gt; [Latest MingW download breaks g++ -ansi option - ID: 2373234]<br>

&gt;<br>
&gt;<br>
&gt; I had modified &quot;cwchar&quot; file referring to the following site,<br>
&gt; and I could &quot;make&quot; geos-3.0.4 successfully with the latest MinGW.<br>
