Hi all.
I want to ask something about transformation.
First, the thing I want is the building's name of the output including its
coordinates, when I input some coordinates.
There are two projection : UTM-K and WGS84.
I tried the transformation in ArcGIS.
After transfomation UTM-K -> WGS84, I got the Long/Lat.
And I did in Geotools below:
String utmk = "PROJCS[\"UTM-K\",
GEOGCS[\"GCS_Korean_Datum_1985\",
DATUM[\"D_Korean_Datum_1985\",
SPHEROID[\"Bessel_1841\",6377397.155,299.1528128,AUTHORITY[\"EPSG\",\"7004\"]],
TOWGS84[595.48,121.69,515.35,4.115,-2.9383,0.853,-3.408],
AUTHORITY[\"EPSG\",\"1024\"]],
PRIMEM[\"Greenwich\",0.0],
UNIT[\"Degree\",0.0174532925199433]],
PROJECTION[\"Transverse_Mercator\"],
PARAMETER[\"False_Easting\",1000000.0],
PARAMETER[\"False_Northing\",2000000.0],
PARAMETER[\"Central_Meridian\",127.50289027777],
PARAMETER[\"Scale_Factor\",0.9996],
PARAMETER[\"Latitude_Of_Origin\",38.0],
UNIT[\"Meter\",1.0]]";
CoordinateReferenceSystem targetCRS = CRS.parseWKT(utmk);
System.out.println(targetCRS.toWKT());
CoordinateReferenceSystem sourceCRS =
factory.createCoordinateReferenceSystem("EPSG:4326");
MathTransform transform = CRS.findMathTransform(sourceCRS, targetCRS);
GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory( null );
Coordinate coord = new Coordinate( 117.98962262140743, 19.698503226154997 );
Point point = geometryFactory.createPoint( coord );
Geometry geometry2 = JTS.transform(point, transform);
System.out.println(geometry2);
The above code, the value of the meter values converted into Long/Lat values.
If I converted the Long/Lat values in arcgis and enter the above code, would
come up with a value of meter?
And then the output(meter) and the meter values(UTM-K) before converting in
ArcGIS are different.
The coordinates of the building on Google map coordinates is different checked
results.
So how can I do?
Thanks in advanced.
Best Regards.
Kevin Lee.
