Description
geos::geom::Geometry *geom = wktreader.read("POINT Z (-117 33 120)");
fails with the exception "ParseException: Expected 'EMPTY' or '(' but encountered : 'Z'"
It appears that the WKTWriter does not support the Z, M and ZM style SF 1.2 geometries, but since the WKTWriter is implementing this as the default output it should.
Note:
See TracTickets
for help on using tickets.
Added Z, M and ZM reading in trunk (r2994).
Note that there isn't really any validation done that the number of coordinates matches the Z, M or ZM. For "M" geometries the third ordinal of the coordinates is assigned M. For ZM geometries the M is discarded silently.
Minimal testing added in unit tests.
