Now I have some questions, for myself or on behalf of some students.
--------
Index:
1) paper archive data conversion?
2) Corona photos?
3) Cloud tracking from remote sensing imagery?
4) Cellular automata?
5) Deforestation in Costa Rica?
6) Wireless network data dissemination?
7) Meteorology discussion lists?
--------
1) paper archive data conversion?
Are there any paper archive conversion softwares meant for (handwritten)
field observation data ?
2) Corona photos?
Does anyone want to share ideas on the use of Corona photos? Here in
Africa, the colleagues are planning a future project related to land
use/land cover changes and desertification monitoring.
3) Cloud tracking from remote sensing imagery?
One student here in Niamey has started a study on the automatic tracking of
clouds from weather satellite imagery (such as Meteosat or GOES).
We have two questions
- are there GIS packages which allow the dynamic follow-up of topological
relationships between two different datasets at two different time dates
(for instance, one cloud which is broken into several clouds, one cloud
which disappear, and conversely one cloud which is created, or several
clouds which merge into a single one) ?
- are there any analogies with other physical phenomena ?
I know about an algorithme from IRD (Institut de Rechercher pour le
Developpement), Vincent MATHON and Henri LAURENT, 2001, Q. J.R. Meteorol.
Soc, 127, pp. 377-406.
4) Cellular automata?
For the same student , I would like to know some literature references on
cellular automata in GISs.
----------------------------------------
This is taken from the Idrisi manual: "A Cellular Automaton is an agent or
object that has the ability to change its state based upon the application
of a rule that relates the new state to its previous state and those of its
neighbors. Thus the main elements of CA applications include cells, states,
neighborhoods and rules."
Cormas is a package from Cirad in Montpellier, used in multi-agent and
cellular automata modelization. This tool is limited to small grids only.
5) Deforestation in Costa Rica?
A friend needs information about deforestation in Costa Rica.
6) Wireless network data dissemination?
I would like to know if there are some projects about dissemination of GIS
data by internet or network, and particularly:
- by wireless / mobile telephony
- by satellite connection (such as VSAT).
7) Meteorology discussion lists?
Does anyone knows whether there is an equivalent list to GISLIST for
meteorologists?
I have found old addresses which are not very well up-to-date.

"The URL to the Virtual Library of Meteorology has changed to
http://www.ugems.psu.edu/~owens/WWW_Virtual_Library/
New administrator is now
Thomas Owens"
http://www.ugems.psu.edu/~owens/WWW_Virtual_Library/
"The dnsserver returned:
Name Error: The domain name does not exist."
An advanced search for "Virtual Library of Meteorology" on
http://fr.altavista.com/searchadv has led me to:
http://dao.gsfc.nasa.gov/DAO_people/towens/VLM/
"WWW Virtual Library

PLEASE CHANGE YOUR BOOKMARKS:

browser underlines URL's"
:-)
From there, I got Meteorology: Mailing Lists
http://dao.gsfc.nasa.gov/DAO_people/towens/VLM/maillist.html
With a few examples, but these lists do not seem to be very active any longer:
MET-AI
a mailing list for meteorologists and AI researchers interested in
applications of artificial intelligence to meteorology.
Suitable topics for discussion include (but are not limited to)
Applications of machine learning to weather forecasting
Artificial neural networks in meteorology
Automatic interpretation and analysis of satellite imagery
Automatic synthesis of weather forecast texts
Case-based reasoning and meteorology
Expert systems and decision aids for weather forecasting
High-level interfaces to archives of meteorological data
Statistical pattern recognition
MET-AI is an unmoderated mailing list.
Problems and suggestions to Eric Jones (Eric.Jones@comp.vuw.ac.nz).
METSTUD
The Meteorology Student Mailing List is open to all, but is particularly
intended to facilitate communication between both meteorology students and
future meteorology students worldwide. The list was founded by Dennis
Schulze at the Free University of Berlin. Dennis has graduated from school
and has turned ownership of the list over to Tommy Owens at Penn State
University.
Subjects of discussion could include but are not limited to scholarships,
summer schools, conferences, and comparisons of the meteorology programs at
various
