Subject [jira] [Updated] (SIS-163) Unsupported WKT 2 features
Date Thu, 13 Feb 2014 23:14:20 GMT

Martin Desruisseaux updated SIS-163:
------------------------------------

    Description: 
This page lists the WKT 2 features which are currently not supported in Apache SIS. Support
for those features may be added in future SIS versions if there is a need for them.

h3. Time extent with named eras.
| *Currently supported:* | {{TIMEEXTENT\[2013-01-01, 2013-12-31\]}} |
| *Not yet supported:* | {{TIMEEXTENT\["Jurassic", "Quaternary"\]}} |

h3. Character encoding restriction
ISO 19162 requires that we restrict to the following characters in all quoted texts except
in {{REMARKS}} elements:

{noformat}
A-Z a-z 0-9 _ [ ] ( ) { } < = > . , : ; + - (space) % & ' " * ^ / \ ? | °
{noformat}

They are ASCII codes 32 to 125 inclusive except ! (33), # (35), $ (36), @ (64) and ` (96),
plus the addition of ° (176). In particular, the specification recommends:

* to use (_P_, _L_) as the transliterations of the Greek letters (_phi_, _lambda_) in axis
abbreviations, or alternatively (_B_, _L_) or (_lat_, _long_),
* to use (_U_) as the transliteration of (_theta_) in polar coordinate system,
* to use (_V_,_V_) at the transliteration of (_phi_, _theta_) in spherical coordinate system.

Those restrictions are currently not enforced in SIS.
