Geotools people,
I know I have not been the most responsive module maintainer in the
history of this project, but can we at least update Jira to assign new
data-VPF issues to me? I didn't even know about GEOT-2094 until I was
contacted directly by the person who was trying it.
Meanwhile, in what branch should I be making these changes? If my
commit rights still work, I will be happy to make the changes.
Regards,
Jeff

Paul,
In VPFColumn.java, around line 205, there is an isGeometry method, but
the check is wrong. It should be:
return attribute instanceof GeometryDescriptor;
Also, don't forget to import:
import org.opengis.feature.type.GeometryDescriptor;
This should give you actual Geometry columns that you can work with.
Regards,
Jeff

Paul,
I haven't forgotten about you, but unfortunately I'm really strapped for
time right now and I don't expect for the situation to improve for at
least another week. I suggest taking a look at the isGeometry method.
Hopefully something there will make some sense.
Regards,
-Jeff

Okay, I'm sorry that didn't work. I won't be able to take a full look
at this until Thursday at the earliest. The first place I'm going to
look is the isGeometry method. This worked at one time, but I guess
there was a regression of some sort.
Regards,
-Jeff

Mr. Yutzler,
Thank you for the answer!
I inserted a check if "gat" is not null in VPFFile()
if (gat != null)
b.setDefaultGeometry(gat.getLocalName());
Then the nullPointerException dissappered but it did not find any
Geometry columns at all in any of the files.
Then I had to do the same in VPFFeatureClass.java :
if (gat != null)
b.setDefaultGeometry(gat.getLocalName());
and of course, no geometry colums were found there either.
What I want to do is to read a VPF map and convert it to another format,
thats all.
Kind regards,
Paul Malm

Mr. Malm,
The code in question does not look like mine. It would be
uncharacteristic for me to name a SimpleFeatureTypeBuilder "b". My
guess is that some refactoring work was done after I stopped working on
the project (I did my work about 4 years ago) and that this work
assumes that the "gat" will be populated. If I recall correctly, some
VPF "feature types" don't actually have geometries so this is an unsafe
assumption. My suggestion is simply to place a sanity check around the
call to setDefaultGeometry and to proceed from there.
If this doesn't work (the "gat" is NEVER populated), please let me know
and I will try to investigate further.
Regards,
Jeff

Subject: VPF question
Hi Jeff!
I have tried to mail the user group without any luck, therefore I'm
trying with you directly.
If you have the time to point me in the right direction I would be very
gratefull !
I don't know anything about the VPF - format.
I've downloaded geoTools 2.5.2 because I saw that it was possible to
read VPF files with tis tool kit.
Indata = eurnasia downloaded from NGA.
When I run the following command
DataStore ds = new org.geotools.data.vpf.VPFLibrary( new File
"C:\test\eurnasia\lib_007" ); // where the lht file is placed
I'm getting an exception;
Exception in thread "main" java.lang.NullPointerException
at org.geotools.data.vpf.file.VPFFile.<init>(VPFFile.java:171)
at
org.geotools.data.vpf.file.VPFFileStore.findFile(VPFFileStore.java:137)
at
org.geotools.data.vpf.file.VPFFileStore.getSchema(VPFFileStore.java:86)
at
org.geotools.data.vpf.file.VPFFileFactory.getFile(VPFFileFactory.java:13
5)
at org.geotools.data.vpf.VPFLibrary.<init>(VPFLibrary.java:171)
at org.geotools.data.vpf.VPFLibrary.<init>(VPFLibrary.java:156)
at VpfTest.main(VpfTest.java:22)
because of this function:
public VPFFile(String cPathName) throws IOException, SchemaException {
pathName = cPathName;
inputStream = new RandomAccessFile(cPathName, ACCESS_MODE);
readHeader();
GeometryDescriptor gat = null;
VPFColumn geometryColumn = null;
Iterator iter = columns.iterator();
while (iter.hasNext()) {
geometryColumn = (VPFColumn) iter.next();
if (geometryColumn.isGeometry()) {
gat = geometryColumn.getGeometryAttributeType();
break;
}
}
SimpleFeatureType superType = null;
// if it's a text geometry feature type add annotation as a
super type
if (pathName.endsWith(TEXT_PRIMITIVE)) {
superType = AnnotationFeatureType.ANNOTATION;
}
SimpleFeatureTypeBuilder b = new SimpleFeatureTypeBuilder();
b.setName( cPathName );
b.setNamespaceURI("VPF");
b.setSuperType(superType);
b.addAll( columns );
b.setDefaultGeometry(gat.getLocalName());
featureType = b.buildFeatureType();
}
gat is null when trying to get localName()
geometryColumn.isGeometry() is allways false !
Kind Regards,
Paul Malm
