this page is to support the GIS.stackexhange.com
of the same name, namely how does one most efficiently use arcgis and
feature classes to achieve some the same things which used to be
possible with arcinfo workstation and region sub-coverages.
Please see attached archives for a v10 map
which demonstrates the problem and (simulated) desired results, and the
from which the simulation is built.
I think my python-COM environment is messed up.

recipe requires registering com stuff, which conflicts wth
PythonWin's com stuff.
- I'm using Arcgis with python
instead of the shipped 2.5. This hasn't proved problematic before,
but maybe I just haven't wondered into this section of the forest
before (which means I need to eat crow for Jason

How to retrieve members and email of an Active Directory group in a re-usable format.

Open an administrative command shell and:

I been using it for the last ten years!?? department.
Many times in the last decade I'veneeded to*search Active
Directory*for a person's name, login name, what members belong to
what group and so on. Each time the need has been pressing enough I've
gone out and searched the 'net for solutions, and each time after a time
come up with a solution. Said time might have been 10 mintues or 2 hours
depending on what in particular I was trying to do. The solutions I've
found and used ranged from the easy to use

Thanks to the persistence of Kent Nassen and the generosity of Jeff
Wunderlich, the Aurora Text
can be downloaded and registered, “…the .bat file command I use to
register is: ac -reg “Jeff Wunderlich” “xujcwpkgzngqmqn” 1 Feel free to
share it with anyone on the net.”
So what’s the big deal? Well I covered most of it a few years ago in
Musing on the Favourite Text

for joy is that I can, once again, select a column and inserting a
character or range of characters (useful for turning fixed width text
records into delimited text), and filling …continue.
by a conversation with my father eons ago, I'm researching and
experimenting how to create a map in a discontinuous or interrupted
projection. Initially I was thinking of Buckminster Fuller's Dymaxion
Map, but I've since chosen a variant of the Bernard J. S. Cahill's
the Cahill-Keyes M-style.
I've successfully recreated the single octant and eight octant Open
Office drawings from the macros and instructions provided. It took a
couple of hours because I had to figure out how OO macro dialogs work,
and don't. There were some errors at the beginning that went away by
themselves -- which always make me nervous because one is never sure if
one day they might also decide to come back by themselves! I used OO
v3.2 on linux so that may have contributed to the difficulty.
Results are at

Anyway, the upshot is now I have a practical understanding of …continue.
Hello there, welcome to the web abode of Matt Wilkie. I've been employed
as a GIS Technician, now Geomatics Analyst, since 1992 or so. If the job
title is new to you, it's a fancy way, make that an opaque way, of
saying I use computers to make maps -- thus the moniker -- and a great
deal of other things related to that process.
I'm drawn to computer based communication systems, having run the gamut
newsgroups, collaborative web editing platforms (drupal, expression
engine), wikis (meatball,
and so on. Having now run some dozen or so of these sites in the last
decade and a half I've come …continue.
In the spring of 2007 the Natural Resources Department of Canada

Although the data has been out for 5 months or so, as near as I can tell
it has yet to be used in any significant public way (no one has been
yapping about it outside the confines of their cubicle). The sole
reference I could find is Stewart Russell’s my neighborhood, according

After a lot of hairpulling and asking smart people for help (Mark
Cederholm, Kirk Kuykendall) I have a working python script which
searches a file geodatabase and changes the AliasName of the matching
feature classes from the incomprehensible BS_1370009_2 to the
human friendly Residential Area
. It does the same for a subset
of the attribute names.
AlterAlias.py can be nabbed from my bitbucket canvec
It relies on
(necessary portion of which is bundled as parco.py)
I took the route of changing the aliasname instead of the fc_name to
make it easier, I hope, to automatically incorporate the twice annual
