#1005: Writing POINT EMPTY in WKB
------------------------+--------------------------
Reporter: Mike Taves | Owner: geos-devel@…
Type: defect | Status: new
Priority: major | Milestone:
Component: Default | Version: master
Severity: Annoyance | Keywords:
------------------------+--------------------------
An empty point can be created in GEOS by reading the WKT `POINT EMPTY` or
the WKB `0101000000000000000000F87F000000000000F87F` (i.e. "POINT(NaN
NaN)").
This point can be written back by GEOS as WKT to get `POINT EMPTY`,
however it cannot be converted back to WKB, as
[https://github.com/libgeos/geos/blob/030ee891c8bf571f37174b51084e76c01d738950/src/io/WKBWriter.cpp#L126-L127
WKBWriter.cpp will throw]:
> `util::IllegalArgumentException("Empty Points cannot be represented in
WKB")`
Given that GEOS is happy to read/write `POINT EMPTY` and read the WKB,
shouldn't it be able to write the WKB geometry too?
See PostGIS [https://trac.osgeo.org/postgis/ticket/3031 ticket #3031] for
related discussion.
