Hi,
Just a thought for a "convert geometry to points" v2.0
If you add three attributes to each point : point, line, and part indices
you'll be able to create a plugin to convert the points back to the
original geometries
I can't describe a particular use case but I have already been asked for
that (may be useful if you have to process the data out of jump to do
special data transformation)

Hi,
I agree with Martin, extracting points from geometries is a common need
which is worth doing (I already wrote the script several times,
never took
the time to code a plugin).
Here is a short script which should do the job :
points = new ArrayList();
for (f :
wc.layerNamePanel.selectedLayers[0].featureCollectionWrapper.features)
{
for (c : f.geometry.coordinates) {
points.add(f.geometry.factory.createPoint(c));
}
}
wc.layerManager.addLayer("NewCategory",
"ExtractedPoints",com.vividsolutions.jump.feature.FeatureDatasetFactory.createFromGeometry(points));

Peppe,
If you can't code this for yourself I can probably take care of it on
my lunch break tomorrow. Just let me know.

Do you really need one, over and above that Peppe clearly has a need

this?
This seems like such a simple extension to ExtractSegements that it's
probably worth doing "just in case"...

So, does OJ need a new function like Extract Segments that would
Extract
Points? What would be the use case?

what about Edgars geometry conversion Plugin? does it preserve

Hi,
today I needed to extract the vertices from a line layer.
Basically I wanted to create a new point layer: the vertice of
the lines with attributes derived from the original lines.
Well, I probabily have to read back the help.. but I did not
find a function like this. A suggestion?
Thanks in advance
Peppe
