Title: Message Title

Brad Hards created an issue   GeoTools / GEOT-5278 Add support for new-style coordinate WKT (OGC 12-063r5) Issue Type: New Feature Affects Versions: 15-beta Assignee: Unassigned Components: referencing Created: 31/Oct/15 8:18 AM Priority: Medium Reporter: Brad Hards GeoTools referencing wkt parser does not appear to handle the WKT format presented in OGC 12-063r5. Here is a junit test example that shows the problem: -- a/modules/library/referencing/src/test/java/org/geotools/referencing/wkt/ParserTest.java +++ b/modules/library/referencing/src/test/java/org/geotools/referencing/wkt/ParserTest.java @@ -383,4 +383,30 @@ public final class ParserTest { public void testAuthorityCodeParsing() throws IOException, ParseException { testParsing(new Parser(), "wkt/AuthorityCode.txt"); } + + @Test + public void test12_063r5() throws ParseException { + final Parser parser = new Parser(); + + String wkt1 = "PROJCRS[\"ETRS89 Lambert Azimuthal Equal Area CRS\", BASEGEODCRS[\"ETRS89\",\n" + + " DATUM[\"ETRS89\",\n" + + " ELLIPSOID[\"GRS 80\",6378137,298.257222101,LENGTHUNIT[\"metre\",1.0]]]],\n" + + " CONVERSION[\"LAEA\",\n" + + " METHOD[\"Lambert Azimuthal Equal Area\",ID[\"EPSG\",9820]],\n" + + " PARAMETER[\"Latitude of origin\",52.0,\n" + + " ANGLEUNIT[\"degree\",0.0174532925199433]],\n" + + " PARAMETER[\"Longitude of origin\",10.0,\n" + + " ANGLEUNIT[\"degree\",0.0174532925199433]],\n" + + " PARAMETER[\"False easting\",4321000.0,LENGTHUNIT[\"metre\",1.0]],\n" + + " PARAMETER[\"False northing\",3210000.0,LENGTHUNIT[\"metre\",1.0]]],\n" + + " CS[Cartesian,2],\n" + + " AXIS[\"(Y)\",north,ORDER[1]],\n" + + " AXIS[\"(X)\",east,ORDER[2]],\n" + + " LENGTHUNIT[\"metre\",1.0],\n" + + " SCOPE[\"Description of a purpose\"],\n" + + " AREA[\"An area description\"],\n" + + " ID[\"EuroGeographics\",\"ETRS-LAEA\"]]\n"; + assertTrue(Symbols.DEFAULT.containsAxis(wkt1)); + DefaultProjectedCRS crs1 = (DefaultProjectedCRS) parser.parseObject(wkt1); + } } That example dies at the `PROJCRS` part - it used to be `PROJCS` in OGC 01-009. Probably an easy fix for that part, but far from the only issue in supporting the new WKT while maintaining support for the old format too. There are additional samples in http://docs.opengeospatial.org/is/12-063r5/12-063r5.html#68 (which is where that WKT comes from). There is some conversion guidance in Appendix C of the OGC spec. Perhaps the biggest pain point is that TOWGS84 goes away... Add Comment   This message was sent by Atlassian JIRA (v7.0.0-OD-08-002#70107-sha1:3f098e8)
