    For JTS there has been no substantive change from the situation in
    the mentioned thread.  I have however been thinking about how to add
    Measure support, both in a non-breaking way to the current JTS, and
    as part of a thorough revamp of the core Geometry API (JTS 2!).<br>
    <br>
    But I'm not sure how this will translate to GEOS. From Sandro's
    comments about the performance cost of making Coordinate a virtual
    class it sounds like this would actually be harder for GEOS than for
    JTS.<br>
    <br>
    For the record, my current thinking it should be possible to provide
    a CoordinateZM class for JTS, which extends the current Coordinate
    class, and which can be used by specifying a matching
    CoordinateZMArraySequence.  Then there's the issues of how far
    exactly the M support should extend.  WKT probably...  WKB perhaps? 
    Other I/O classes (Oracle could use this...).  <br>
    <br>
    All it takes is time and money...<br>
    <br>
    As for other SFS 1.2 types - ditto.<br>

      <div>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 ;)</div>
      <div><br>
      </div>
      <div>Do you think GEOS will support all the SFSQL 1.2 types?</div>
      <div><br>

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