Hei,
I believe Paul is in holidays. So we may need to wait until he is back.

I was about to test WMS with basic authentication, but the newest nightly build is four days old, from 8th of May.

Aihe: Re: [jump-users] Union with attributes
Hei Ravi,
I (hopefully) finsihed the plugin/function today.
However, the stuff/task is non trivial from my perspective.
So It works only for polygon layers now. It could be also
used for LineString Layers, but I disabled it as the Planar
Graph Function has similar functionality. Merging mixed
Geometry layers is quite difficult. For instance right now I
don't have an idea how to do that properly for Lines and
Polygons - although this may be a useful function.
The function is located under Tools/Analysis/Intersect Polygon Layers
You may wonder why I did not call it "union" as in ArcGIS.
The reason is simply that the topological operations used are
intersections. And I think we should try to avoid using wrong
(but probably older ESRI) terminology.
Can you test if it does what it is supposed to? At least it
worked for me with the testdata you sent.
cheers,
stefan
PS: I won't do this "customization" work often.. but as you
asked for a long time... ;)
Next thing to do is to transfer some of the Pirol plugins (creating
Grids) and Layer Attribute Statistics, that are not contained
anymore in the PirolJUMP (wonder why)

Hi,
for mineral prognastication, tried to have result A shape
(attribute
CODE) + Bshape (Attribute Number) = Polygons with
attributes (Code and
Number) from both layers, only populated If they intersect.
Example:
1.For the resultant polygon pieces, Code=1, Number=200 when they
intersect 2.For the resultant polygon pieces, Code=1,
Number=0 or NA
when they donot intersect.
Method:
1. A and B layers are selected and Replicated to a NewLayer with
right click menu.
2. NewLayer is polygonised and renamed as AB (it has no attributes)
TRANSFER OF ATTRIBUTES
3. Tools --> Edit Attributes --> Transfer Attributes
Layer A= AB
Layer B= A
Realation= Contains
Un-Expected Result: Though the smaller polygons of AB are
contained by
A polygon layer only a few are transfered.
Had this worked then with these steps, the UNION as desired
could be
achieved, by repeating a few steps.
