Martin Desruisseaux updated SIS-163: ------------------------------------ Affects Version/s: 0.6 > Unsupported WKT 2 features > -------------------------- > > Key: SIS-163 > URL: https://issues.apache.org/jira/browse/SIS-163 > Project: Spatial Information Systems > Issue Type: Task > Components: Referencing > Affects Versions: 0.4, 0.5, 0.6 > Reporter: Martin Desruisseaux > Priority: Minor > > This page summarizes the WKT 2 features which are currently not supported in > Apache SIS. More details are provided in the sub-tasks for unsupported > elements and restrictions. The third sections is about recommendations that > are not mandatory, but that we do not yet follow. > h3. Unsupported WKT elements > * {{ParametricCRS}} (we need an implementation in the rest of SIS first). > * {{Bearing}} element for polar coordinate systems having a "clockwise" or > "counterClockwise" axis direction. > * {{BoundCRS}} element as the successor of the WKT 1 {{TOWGS84}} element. > * Time extent with named eras (e.g.{{TIMEEXTENT\["Jurassic", "Quaternary"\]}}) > h3. Restrictions that we do not verify > * ISO 19162 restrictions on {{CompoundCRS}}: (_geographic_ or _projected_ or > _engineering_) followed by (_vertical_ or _parametric_) followed by > _temporal_. > * ISO 19162 restrictions on axis name, abbreviation and directions (e.g. > geographic CRS shall be ‘_latitude_’, ‘_longitude_’). > * Precedence of EPSG codes over names for {{Conversion}} objects. > h3. Recommendations that we do not yet follow > * Formatter should be able to write the short WKT 2 keywords (currently we > format only the long ones, because they match the type names). > * We do not check the recommended maximum string lengths (80 characters in > names, 255 characters in other quoted texts, 4096 in total). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
