Hi guys,

What are GEOS users and devs doing to enable M measures in their GEOS-backed solutions?  I won't worry about specialised functions at this point, but at least being able to reliably handle and maintain all XYZM ordinates is important for me.  Is it such a lot of work that it's not worth adding this to GEOS?  I saw a few messages in the archives looking at how to add measures but it wasn't encouraging ;)

Do you think GEOS will support all the SFSQL 1.2 types?

Are people moving to Boost or CGAL instead?  Would love to hear thoughts on it.
