Wrong attributes when reading shape files with bad LinearRings
--------------------------------------------------------------
Key: GEOT-3367
URL: http://jira.codehaus.org/browse/GEOT-3367
Project: GeoTools
Issue Type: Bug
Components: data shapefile
Affects Versions: 2.6.5
Environment: Mac OS X 10.6.5, Java 1.6.0_22
Reporter: Marcel Rieser
Assignee: Andrea Aime
I'm trying to read in a shape file from
<http://download.geofabrik.de/osm/europe/> (Shapefile-Exports from
OpenStreetMap), sadly those files contains shapes that produce the error:
java.lang.IllegalArgumentException: Points of LinearRing do not form a closed
linestring
at
com.vividsolutions.jts.geom.LinearRing.validateConstruction(LinearRing.java:105)
When I try to try-catch those exceptions to at least read in all the other
shapes, the attributes begin to mismatch: The attributes for the
non-closed-shape are returned with the next closed-shape. It looks like there
are two different Iterators (one for the shape, one for the attributes), and in
the case of the exception only the first one get's forwarded, but not the one
for the attributes.
Is there any way to disable the LinearRing-Validation completely? Other
GIS-Applications (e.g. QGis) happily work with those shapefiles, only
GeoTools/uDig has problems with those.
