Hei Michael,
a long answer
I) Minority/Majority/Median:
they are only applicable to integer or string values - end return the
value that occurs the most = majority, or the least = minority* (i.e. by
counting the occurence). The median is the value right in the middle if
we build an ordered set
ups sorry - I was wrong. The LinearRings seem to come from somewhere
else (i.e. geometry.getBoundary() ... which makes sense)

Hei Martin,
thank you for the answer.
I just recognized that the method that delivers the LinearRings is
lineMerger.getMergedLineStrings()
can you check that? is that a bug or intended behaviour? (I see in the
javadoc that LinearRings is a subclass of LineString)

It's certainly easier to do for raster analysis - I think there's fewer
corner cases and exception. But FME provides an example of doing this
for vector-based analysis.

Yes, that's exactly it. JEQL will provide an enhanced spatial SQL which
can be used on JUMP layers.
Now I just have get busy and write the UI component... !

I think this function could return LineStrings only.
(but jml should also be able to read/write linearring correctly...)

Hey, I did not notice that. I'll have
I think the LinearRings are simply saved as LineStrings to shapefiles -
that's why that works.
The inability to load LinearRings from JML is probably just an oversight
in the original implementation. Although, it looks to me like GML2 does
not actually support LinearRings as geometries in their

Not sure if this is quite on the same track, but I'm planning to make a

Zmitser,
Sorry I haven't gotten back to you for a couple of days. I had a busy weekend.
Do you think you can handle setting up an Eclipse Java development
project for your plug-in? You'll need to create a new Java project and
add then JTS/JUMP libraries to your projects build path.
