KML does not write Z value if dimension is greater than 3
---------------------------------------------------------
Key: GEOT-3201
URL: http://jira.codehaus.org/browse/GEOT-3201
Project: GeoTools
Issue Type: Bug
Components: core xml
Affects Versions: 2.7-M2
Reporter: Jose Martinez-Llario
Priority: Minor
When I use GeoTools to encode a geometry into a KML I have a problem when my
geometry has 4 dimensions: GeoTools skips the z coordinate in kml. I have
modified JTS slightly to handle geometries with 4 dimensions.
I was wondering if it is possible to change the following line in the class:
CoordinatesTypeBinding.java (org.geotools.kml.bindings). The change is just
to change the == 3 by >= 3.
public String encode(Object object, String value) throws Exception {
............
if ( cs.getDimension() == 3 && !Double.isNaN( c.z ) ) {
sb.append(",").append( c.z );
}
..............
}
Result:
public String encode(Object object, String value) throws Exception {
............
if ( cs.getDimension() >= 3 && !Double.isNaN( c.z ) ) {
sb.append(",").append( c.z );
}
..............
}
The code will work exactly the same way than before but it will write the z
coordinate with 4 dimension coodinates.
Hope it can help.
