I am currently migrating geotools and geoserver to use the new
ContentDataStore based gt-propery-ng module. During testing on geoserver, I
am getting a test failure that I can't seem to figgure out:
The test GetFeatureCurvesTest.testLinearizeWFS10() fails at line 105:
assertTrue(coordCount100m > coordCountDefault);
From what I can determine, the test queries the feature source, then sets
a Linearization tolerance and queries it again. Line 105 suggests that it
expects to get more coordinates returned form the second query.
I am mostly wondering why it is expected that the Linearized geometry has
mote coordinated than the default geometry, but if anyone has any insights
into how changing the behaviour of PropertyDataStore could affect this
result that would also be helpfull.
If the geometry is curved it will inearize itself on demand,normally by
using a default lineaziation tolerance.
However, if we change it by using the query hints, we can get back a
different (larger) set of coordinates.
PropertyDataStore uses a WKTReader2, which is setup by checking the query
hints for the desired tolerance:
@Override
protected FeatureReader<SimpleFeatureType, SimpleFeature>
getFeatureReader(
String typeName, Query query) throws IOException {
PropertyFeatureReader reader = new PropertyFeatureReader(directory,
typeName);
Object toleranceHint =
query.getHints().get(Hints.LINEARIZATION_TOLERANCE);
if(toleranceHint instanceof Double) {
double tolerance = (double) toleranceHint;
reader.setWKTReader(new WKTReader2(tolerance));
}
return reader;
}
Is the new store doing the same?
Cheers
Andrea
