I would like to be involved with this work on GIS issues and I would be
pleased to lead such a subgroup within the scope of the EM TC.

The point about "interfaces" is very relevant as the GIS community
has long advocated a "services-orieneted architecture" based on
international standards. International standards supporting discovery
of and access to geospatial data and services are agreed upon through
the various Spatial Data Infrastructure initiatives. These include
ISO 23950 for the "catalog service" interface. Among the geospatial
interfaces developed and prototyped by the OpenGIS Consortium are a
"Web Mapping Service" that specifies how to use HTTP GET to obtain
rendered maps (e.g., GIF and JPG images) with specific layers at
particular places.
In an Emergency Management context, my sense is that the ISO 23950
catalog service and the OGC Web Mapping Service are the most critical
services to advocate for immediate and widespread deployment.

Another reference is the "Clearinghouse" of the National Spatial Data
Infrastructure (NSDI) http://www.fgdc.gov/clearinghouse/clearinghouse.html.
Although coordinated by a Federal interagency group, the NSDI includes
participants at all levels of government and other sectors as well.
Vendor-led initiatives such as ESRI's Geography Net are also
interoperable with NSDI through support of the standard services.

MEETING MINUTES:
Many thanks to Gary Ham who helped summarize the meeting - since I wasn't
feeling 100%! Many of these notes are his.
Allen started the meeting by noting that OASIS is in the midst of
switching to a new collaboration system and there may be problems
accessing stored information on the emergency list. If you are still
having trouble when you receive this email, please email Allen
(awyke@blue292.com) and he will address the issue.
The subjects of interest then discussed at the meeting included:
1. Requirements Document and Organization of Requirements.
2. Chosen areas of subcommittee concentration.
3. Standards discussion
4. Liaison with apparent duplications of effort.
Requirements Document.
Allen had updated the document with edits from the last meeting and any
emails since the last meeting.
Gary brought up the idea that we need to organize our documentation around the
incident command system structure as that would likely be the structure
for NIMS and NIMS-related artifacts was presented (see notes from last
week's meeting for more detail on NIMS). There was some discussion and
general agreement, but based upon a suggestion from several of the TC
members that we try to avoid the "process wars" the committee agreed to
weaken the explicitness of support for ICS, while still using it as a
general framework. In other words we would support other frameworks as
well, when needed. Gary will bring more detail about NIMS and ICS to the
face-to-face meeting. In summary Allen stated that the group should
identify which of the areas noted in the Requirements Document support the
ICS framework - planning, operations, logistics and financial
administration - and organize our components to support that structure.
Several minor changes to the Requirements document will be made and a
"final" copy posted for next week.
Gary also addressed the meeting he, Allen, and Matt Walton (Chairperson, EM-XML
Executive Committee) and Mark Zimmerman (DHS) attended with Steve Cooper
(DHS CIO) on Monday. They had twenty minutes of his time. Matt Walton
gave an explanation of the EM-XML consortium and how it related to
Homeland Security Presidential Directive #5 (see last week's meeting notes
for detail). Mr. Cooper promised to put someone from his shop on both the
EM-XML Executive Committee and the EM TC.
Subcommittee Concentration.
