probably rather to this list ;) -------- Original-Nachricht -------- Betreff: [jump-devel] Projection with Geotools2 CRS Datum: Thu, 13 Sep 2007 21:00:44 +0200 Von: Edgar Soldin <[EMAIL PROTECTED]> Antwort an: JUMP Developers <[EMAIL PROTECTED]> An: JUMP Developers <[EMAIL PROTECTED]>
Hello All, because of all the comments related to projection (interfaces) , here is an example of the simplicity in using GT2 CRS for projection/transformation SNIPPET--> CoordinateOperationFactory coFactory = FactoryFinder.getCoordinateOperationFactory(null); MathTransform transform; src = FactoryFinder.getCRSFactory(null).createFromWKT("PROJCS[\"DHDN / Gauss-Kruger Zone 3\", GEOGCS[\"DHDN\", DATUM[\"Deutsches Hauptdreiecksnetz\", SPHEROID[\"Bessel 1841\", 6377397.155, 299.1528128, AUTHORITY[\"EPSG\",\"7004\"]], TOWGS84[598.1, 73.7, 418.2, 0.2019999999999998, 0.04499999999999995, -2.4549999999999974, 6.7], AUTHORITY[\"EPSG\",\"6314\"]], PRIMEM[\"Greenwich\", 0.0, AUTHORITY[\"EPSG\",\"8901\"]], UNIT[\"degree of angle\",0.017453292519943295], AXIS[\"Geodetic longitude\",EAST], AXIS[\"Geodetic latitude\",NORTH], AUTHORITY[\"EPSG\",\"4314\"]], PROJECTION[\"Transverse_Mercator\"], PARAMETER[\"semi_major\", 6377397.155], PARAMETER[\"semi_minor\", 6356078.962818189], PARAMETER[\"central_meridian\", 8.999999999999991], PARAMETER[\"latitude_of_origin\", 0.0], PARAMETER[\"scale_factor\", 1.0], PARAMETER[\"false_easting\", 3500000.0], PARAMETER[\"false_northing\", 0.0], UNIT[\"metre\",1.0], AXIS[\"Easting\",EAST], AXIS[\"Northing\",NORTH], AUTHORITY[\"EPSG\",\"31467\"]]"); //src = FactoryFinder.getCRSAuthorityFactory("EPSG", null).createCoordinateReferenceSystem("EPSG:31467"); trg = FactoryFinder.getCRSAuthorityFactory("EPSG", null).createCoordinateReferenceSystem("EPSG:4326"); CoordinateOperation co = coFactory.createOperation(src, trg); transform = co.getMathTransform(); <--SNIPPET the snippet is only rough cut out of my tests. It will not compile in this state, but still it shows how easy it is with GT2 to get a transformation (from WKT or EPSG ID, as you choose) for projecting coordinates. The EPSG entries of the factory are of course request-/listable by name(description). just trying to lobby for the GT2 library, as I get the impression the list is a bit afraid of it ;). regards ede -- public class WhoDidIt{ // A comment.
