Hi,
reviewing the WMS 1.3 and WMS 1.1 capabilties documents I've noticed
that in the WMS 1.1 one we have, for each layer, a comment showing
the full WKT syntax for the native CRS of that layer, for example:
<SRS>EPSG:4326</SRS>
<!--WKT definition of this CRS:
GEOGCS["WGS 84",
DATUM["World Geodetic System 1984",
SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
UNIT["degree", 0.017453292519943295],
AXIS["Geodetic longitude", EAST],
AXIS["Geodetic latitude", NORTH],
AUTHORITY["EPSG","4326"]]-->
....
<SRS>EPSG:3010</SRS>
<!--WKT definition of this CRS:
PROJCS["SWEREF99 16 30",
GEOGCS["SWEREF99",
DATUM["SWEREF99",
SPHEROID["GRS 1980", 6378137.0, 298.257222101,
AUTHORITY["EPSG","7019"]],
TOWGS84[0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0],
AUTHORITY["EPSG","6619"]],
PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
UNIT["degree", 0.017453292519943295],
AXIS["Geodetic longitude", EAST],
AXIS["Geodetic latitude", NORTH],
AUTHORITY["EPSG","4619"]],
PROJECTION["Transverse_Mercator", AUTHORITY["EPSG","9807"]],
PARAMETER["central_meridian", 16.5],
PARAMETER["latitude_of_origin", 0.0],
PARAMETER["scale_factor", 1.0],
PARAMETER["false_easting", 150000.0],
PARAMETER["false_northing", 0.0],
UNIT["m", 1.0],
AXIS["Easting", EAST],
AXIS["Northing", NORTH],
AUTHORITY["EPSG","3010"]]-->
This adds quite a bit of extra text to the caps document, and if you check,
it's
not available in the WMS 1.3 ones.
The code generating it dates back to Dave Blasby times:
// DJB: I want to be nice to the people reading the capabilities
// file - I'm going to get the
// human readable name and stick it in the capabilities file
// NOTE: this isnt well done because "comment()" isnt in the
// ContentHandler interface...
try {
CoordinateReferenceSystem crs =
layer.getResource().getCRS();
String desc = "WKT definition of this CRS:\n" + crs;
comment(desc);
} catch (Exception e) {
if (LOGGER.isLoggable(Level.WARNING)) {
LOGGER.log(Level.WARNING, e.getLocalizedMessage(), e);
}
}
I'm wondering if we should remove it, or at least make it optional somehow.
Maybe kill it, but have a system variable that one can set it re-estabilsh
it
in case any application really needs it?
Cheers
Andrea
