Shared CRS and CRS Transformation Library

=Introduction=
This page was created for information and discussion on a library for CRS and CRS transformations that might be shared among Kava GIS programs.
=Moving Forward=
I don't think it is realistic for us to expect either GeoTools or
deegree to abandon their existing CRS code. However, I think we can
start laying the foundation for a shared library at some point in the
future, even if it is a couple of years away. This is the approach
Jody and I discussed with the DataObjects framework for obtaining a
generic Feature object from common spatial file formats. 
=Proposed Tasks=
I believe that we can move forward with the following tasks:
*Identify what the GeoTools and deegree CRS source code is
currently capable of. What can each library do and what can't it do?
If a programmer from each project can send me a short description of
this functionality I'll get it posted to the OSGeo Java Collaboration
page.
*Identify the things that we can share without major changes to
each library. I would think at a minimum this would include CRS
definitions and common transformation algorithms.
*Identify interfaces in each library that serve the same purpose or
close to the same purpose. These can be targets for interfaces that
can be moved to a common package shared by both libraries at some
point in the future.
*Determine the development road plan for each library. What changes
will be coming to each library in the next month, 6 months, year? If
we can answer this question we can find opportunities to build
similarities into each library as they develop. The result will be two
libraries that grow closer together instead of farther apart.
The Sunburned Surveyor
== Issues For Discussion ==
* Use of ISO 19111 as a document to guide implementation of any library or shared interfaces.
* Use of JSR-275 in any library.
* Where do we want to strike the balance between complexity and simplicity? Can we have a simple core set of packages for the most common use scenarios, and an extended set of packages for the hard core geodesists among us?
* How will we handle licensing and copyright issues? Can we host the code for any shared library in an existing project like GeoTools, GeoAPI, or deegree?
* Can we come up with a list of classes or interfaces that the GeoTools and deegree libraries have in common, and then work on refactoring out a common set of interfaces that can be placed in a shared library?
* What are the sources of projection information available to us (EPSG, PROJ4) and how will a shared library incorporate or integrate those sources? Will we define our own "open" format for CRS definitions? How will this be maintained?

Shirts

This page is all about our Lands' End shirt orders.
We use the Lands' End service for conference shirts and special VIP shirts. Orders are generally placed by mpg or Tyler. Processng and shipping can take up to a week or more, so please get your requests to us well in advance (esp. for international orders).
Individual members who wants shirts (or other swag) should use our CafePress website.
=== Design/Style ===
We have our logo on file at Lands' End. We used them for the Where 2.0 event; we chose fabric style "W", which gave lots of style choices for the order (Tees, etc), all using color=BLACK. They came out nice.
Two images (PDF and EPS) are stored in the VisCom file repository at osgeo.org.

Sig collectivites fr

Dans le but de favoriser le développement du logiciel libre SIG dans les collectivités territoriales, il est important d'en faire la promotion. Pour ce faire, il semblerait intéressant d'arriver à constituer un ensemble de documents pour faciliter l'adoption de solution libre aussi bien pour les spécialistes que pour les élues. 
L'objectif serait de produire : 
* Un cahier de bonnes pratiques des logiciels libres SIG en collectivités
* Un guide pratique pour exiger des composants SIG libres dans un marché public
* Un inventaire des fonctionnalités absentes pour le moment dans les SIG libre et qui sont des freins à l'appropriation de ces logiciels par les collectivités
== Cahier de bonnes pratiques==
Au travers de ce document, il pourrait être possible d'avoir un inventaire d'expériences d'utilisations de SIG libre en collectivité, de présenter des projets qui répondent à des spécificités de collectivités (cadastre, applications métiers).
== Guide pratique pour exiger des composants SIG libres dans un marché public ==
En complément du guide pratique d'usage des logiciels libres dans les administrations (http://www.synergies-publiques.fr/IMG/pdf/FAQ-LL-V1.2.0.pdf), existent-ils des points spécifiques concernant les SIG ?
Comment faire des développements mutualisés ? Comment formuler certaines préconisations pour que les développements spécifiques réalisés dans le cadre d'un marché puisque être réutilisable par d'autre ?
== Inventaire des fonctionnalités absentes dans les SIG libre ==
Cet inventaire permettrait d'identifier quels sont les points de blocages au développement du SIG libre en collectivité, de les inventorier et d'en faire la promotion pour que certaines collectivités puissent prendre en charge certains développements et aussi de réfléchir en amont avec les éditeurs.

Silvia franceschi

I'm an environmental engineer working in the fields of hydrology, geomorphology and hydraulic. 
I love to get lost inside the development of environmental models (which I develop mostly in cooperation with the Faculty of Environmental Engineering of the University of Trento and are released under GPL), for which I need the base given by FOSS GIS software.
For my daily work I use only Free and Open Source products and one of my aims is the widespread of FOSS software in the professional world of engineers and geologists.
Since 2005 I'm cofounder of HydroloGIS where we develop and use JGrassTools, uDig, Geopaparazzi for practical applications. 
We have used our tools for environmental analysis many Italian regions but also in other countries such as Finland, Austria, Zambia, Tibet, Rwanda and Ethiopia.

I am the Director and Principle Consultant of Botanicus Australia Pty Ltd.
I have been involved in the use of geospatial software since 1996, and have been using a wide range of desktop packages to access, analyze and print maps of flora, fauna and vegetation. I currently use gvSIG as my primary GIS solution.
I have a long history in the development of relational databases for the storage of plant and animal locational and monitoring data. I am very familiar with the use of Visual Foxpro, although I also program in a variety of other languages.
In 1993 published the book "Management of Endangered Plants" through CSIRO, encapsulating 5-years research on the monitoring and management of over 200 rare or threatened plant species in Victorian National Parks.
In recent times (2009-2010) I have moved from a totally Windows-based operating system to Ubuntu. Apart from some small legacy programs, written in Visual Foxpro (VFP), all core programs have been replaced by FOSS.
I have been involved in the OSGeo Community since 27 July 2010.

Sixteenth VisCom Meeting

=== Date and Time ===
The meeting will be on January 31st, 2007, at 16:00 UTC []] (8am PST)
The meeting will take place on IRC at #osgeo and as a [conference call].
=== Standing Agenda ===
# Assign scribe
# Roll call
# review of previous meeting's minutes and tasks
# New Business (below)
# Review action items
# Set next meeting date
# Adjourn
== Minutes ==
* Full chat log at: http://logs.qgis.org/osgeo/%23osgeo.2007-01-31.log
* Attending: Tyler Mitchell, Michael Gerlek, Nathalie Mainland, Aaron Racicot, Perry Nacionales, Arnulf Christl
Updating committee membership...
# Michael moved to remove Lisa from membership, with a vote of thanks for her earlier contributions, Tyler seconded, all in favour
# Michael moved to add Aaron Racicot as a member of Viscom, Tyler seconded, all in favour
# Tyler moved to add Nathalie as member of VisCom, Michael seconded, all in favour
# Tyler moved to add Perry N. to committee, Arnulf seconded, all in favour, passed
Some questions about how involved other members in committee are likely to be.
Update from Nathalie...
# Introducing their work on a project with City of San Francisco, which highlights the use of MapGuide Open Source. They are aiming for a launch on March 7th, 2007.
# Answered Nathalie's question re: process for getting news out to public. Consensus is to send items to VisCom list and we'll help direct it for her if there is any doubt.
Event Management discussion...
# Michael described tactics for handling events for the next year, as now documented on http://wiki.osgeo.org/index.php/Event_Plan_2007
# Arnulf pointed us back to the Event Owner requirement http://wiki.osgeo.org/index.php/Event_Management#Event_Owner to help us be effective. 
## Rough discussion centred around funding levels for various size of event, though it was agreed that larger size does always mean more expensive. He explained the need for better ownership/contact for events. 
## Agreed that VisCom has a monitoring role over owners.
# Discussed some of the 'major events' that have been brought forward, where we need to be proactive to get prepared to cover. Several costs were mentioned: financial costs for booth, etc. but also costs to event owner (time) and volunteer resources (time and money).
