Hi all,
I found a code snippet to generate a SVG file:
http://osgeo-org.1803224.n2.nabble.com/How-to-find-added-geometry-in-svg-td5510127.html
I do not know if it's the best way, but at least it worked for me. The
code example
is a refactored version of the following code:
http://www.javadocexamples.com/java_source/org/geotools/svg/GenerateSVG.java.html
In this case I do not know whether it is appropriate to update the
documentation (request or DIY). Now I have another problem: How to generate
an image with several overlapping layers. I tried to simply add a new layer
in MapContext but did not work =(

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
