Re: Horae question

[Stefan Steiniger]

Hi Tad,

first, hope it's fine when I am CC'ing to the user list, so people are
aware that there could be some problem.

Now to your question which puzzle's me a bit. I did some improvements to
MCP that allowed to select the also a 95% contour (as an addition), ad
you can still select what percent-contour you want for the KDE.

If dialog/menu items are missing and selections do not work, then this
seems to be a Java platform issue. So there are three things I would ask
you to test/check:

(a) What happens when you use the dataset coming with Horae? (i.e. KDE:
don't forget to set the correct weight attribute, and select h = 4000
and cellsize=100, then for calculating the contour, you need to select
the generated density layer in the left hand layer menu in the "Result"
category, before calling the contouring function --- for MCP: are you
able to check the "Calculate MCP for fraction of points" box, and then
set values in the text below?

(b) What happens when you use the older version that you head before? -
i.e. simply copy the code or download it again from:
http://gisciencegroup.ucalgary.ca/wiki/index.php/OpenJUMP_HoRAE
or
http://sourceforge.net/projects/mentaer.u/files/moveantools/ojhorae/

(c) What OS and Java version are you using? (Was there some change? -
new computers?)

cheers,
stefan
