<br>
If I understand correctly, Postgis does not handle NULL altitude
in 3D geomtries.<br>
<br>
Hence, when using ST_Force3D, it sets the altitude to 0, which I
find a bit inconvenient (and dangerous).<br>
<br>
1. Is there any ongoing or potential development towards
handling null altitude in geometries or this is not feasible?<br>
<br>
2. Do you have any good workaround? Like using -9999 and
creating your own ST_Force3D?<br>
<br>
Thanks a lot,<br>
<br>
