Just in case anyone isn't familiar with it, the JTS TestBuilder is a Java
GUI application which might be useful for some aspects of GEOS
development.  In particular, it's handy for creating and viewing geometry
test cases.  You can draw and edit geometry, and capture the results as WKT
or WKB (and several other formats as well).  You can also drop an entire
JTS/GEOS Test XML file in order to view all the cases in the file.

It's available as a fat jar from the JTS Releases page:


Docs are limited, but most things have tooltips.  With suitable
encouragement I might even get around to writing a proper manual one day...
