arConnect

Hello List,

Does anyone know if the arcGIS extension called ArConnect (
http://www.gisvet.org/Documents/GisVet04/RegularPaper/Tait.pdf )
is released or available anywhere.  I've had a hard time finding anything
but this one paper.  I'm looking for the most comprehensive tools for kernel
density estimated surfaces (with cross validation bandwidth selection and
the boundary correction).

I think the answer is negative - the project was promising, but it is 
difficult to find subsequent references. If you need to integrate with 
ArcGIS, you may find the code at:

http://www.nicholas.duke.edu/geospatial/software/

of use. From there, you can try to see which kernel density functions in R 
suit you best. If you visit http://www.spatstat.org/, you can find plenty 
of information (ksmooth.ppp), and there are alternatives like kernel2d() 
and mse2d() in splancs, but you'll need to look around to find a function 
to meet your needs.

Roger

Thanks,

Colin
