Martin Desruisseaux commented on SIS-284: ----------------------------------------- Before to close this task, we need to verify that we can decode all the following coordinate operations: {code:java} public class Test { public static void main(String[] args) throws Exception { CoordinateOperationAuthorityFactory factory = (CoordinateOperationAuthorityFactory) CRS.getAuthorityFactory("EPSG"); System.out.println(factory.createCoordinateOperation("15596")); // 3D to 3D System.out.println(factory.createCoordinateOperation("1336")); // 3D to 2D System.out.println(factory.createCoordinateOperation("1335")); // 2D to 2D } } {code} With EPSG geodetic data set 8.9, the first coordinate operation succeed but the next two fails, because the operation method is declared with a {{null}} (meaning arbitrary) source number of dimensions, which is okay, but a target number of dimensions fixed to 3. If the situation is the same in EPSG geodetic dataset 9.0, we may need to force the target dimension to null. > Geographic2D with Height Offsets (EPSG:9618) > -------------------------------------------- > > Key: SIS-284 > URL: https://issues.apache.org/jira/browse/SIS-284 > Project: Spatial Information Systems > Issue Type: Sub-task > Components: Referencing > Reporter: Martin Desruisseaux > Assignee: Martin Desruisseaux > Priority: Minor > Fix For: 0.8 > > > Simplified form of _"Geographic3D to Geographic2D + gravity-related height"_ > transformation used in Japan. > See §2.4.5.3 in IOGP Publication 373-7-2 – Geomatics Guidance Note number 7, > part 2 – April 2015. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
