Converting strange coordinates from shapefile into regular lat and long using GeoTools?

Question

I use this dataset from the European Union:
http://www.eea.europa.eu/data-and-maps/data/administrative-land-accounting-units

Opening the shapefile with Java' Geotools, I see coordinates like:

4591000 2713000

and I would need to translate these into regular lat and long coordinates.

I've seen posts suggesting the .prj file can help solving this problem, so I post its content here:

PROJCS
["ETRS_1989_LAEA",GEOGCS["GCS_ETRS_1989",DATUM["D_ETRS_1989",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Azimuthal_Equal_Area"],PARAMETER["False_Easting",4321000.0],PARAMETER["False_Northing",3210000.0],PARAMETER["Central_Meridian",10.0],PARAMETER["Latitude_Of_Origin",52.0],UNIT["Meter",1.0]]

I am not a specialist of GIS.

Answer 1

The dataset use Pan-European mapping standard projection system - EPSG3035

If you are open to non-java tool and simplicity, you will be able to reproject the file to WGS84 using GDAL/OGR : http://www.gdal.org/, that way :

ogr2ogr -f "ESRI Shapefile" path/to/NUTSV9_LEAC.shp NUTSV9_LEAC_wgs84.shp -s_srs EPSG:3035 -t_srs EPSG:4326

Answer 2

For on-line transformation/convertion use Mygeodata Converter.
