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