In general, timely information on the development
of hazards as well as general information on risks, hazards, and opportunities
remains fragmented and difficult to locate. To begin to address these
and other gaps, prototype tools are being developed. NOAA has sponsored
a prototype information server for the group. This server was intended
to demonstrate timely access to satellite-derived data and information
products (i.e., "one stop shopping") to support various facets of disaster
management. A number of agencies participated in the development of this
service, providing links to their data and information services, and developing
additional support tools for the project. A group information server team
has supported these efforts. As with the rest of the DMSG, the tools team
is currently completing its activities. This report provides a summary
of the teams' activities, identifies goals that were not achieved, describes
why goals were not achieved (lessons learned), and offers ideas on how
others might achieve these goals in the future as the work of the DMSG
is carried forward in other fora.
Many of the activities, such as hazard theme pages and links to other
hazard related web sites have been useful for providing information to
a broad range of users and potential users of hazard information. The
reports and meeting summaries of the DMSG have been used and referenced
by others. Sometimes the "Click here to e-mail us" has been used as a
focal point for soliciting help in addressing specific disaster issues.
In this way, requests for data, information on what data is useful, or
questions regarding scientific phenomena related to specific disasters
are received and relayed to members of DMSG. Often an e-mail dialogue
ensues that leads to resolving the issue. |
A key goal of providing a user-friendly Internet
search capability to access specific data, derived products and other
information for disaster managers has remained elusive. Key problems,
such as -- lack of consistent, consensus on terminology; the cost and
difficulty of achieving the state of the art for search technology; and
the need for specific scenarios have limited achieving this goal. Ironically,
as the work of the team is winding down, significant progress in solving
these problems is emerging. Hopefully, this will encourage others to take
up the challenge.
Quite often users are not familiar with the terminology of data providers.
In fact, user communities often have their own terminology that is quite
different from data providers and other user communities. Within some
user communities there is no standardized terminology established. A key
goal of the information tools development has been to build a bridge between
user and data provider terminology for selected user communities. The
goal was to use the hazard team activities to derive appropriate terminology
where standardized terminology and specific scenarios were not available.
Previous annual hazard team reports did provide useful terminology, but
not until this final report have scenarios been defined. Building on the
scenarios of the International Charter for Space and Major Disasters,
hazard teams have defined several additional useful scenarios. This set
of scenarios will act as a prototype and template for adding additional
scenarios and hazard types in the future. On-going collaboration with
activities of UN organizations such as OOSA and ISDR as well as the Internatianal
Charter will be crucial to maintaining and increasing interaction with
a broader user community as well as making this effort more successful.
For example, the continuation of user-oriented workshops, co-sponsored
by UN organizations and CEOS or CEOS agencies, is strongly encouraged. |
It has been the goal of the information tools team
to have several layers for information access, ranging from a simple list
of key data providers, to the hazard specific scenarios discussed in the
last paragraph, to an Internet-based search of several Earth observing
data and product catalogs. The simple list of data providers should include
key contact information including contact person, telephone number, fax
number, address, and Internet URL if available. When available, contact
information as provided by the CEOS International Directory Network (IDN)
and other FGDC compliant catalogs would be used. This list would start
as a short list focused primarily on space agencies, and grow from there.
Unfortunately, the tools team focused on the more difficult layers, and
as a result did not implement the layer that would have been easiest.
The lesson learned here is to do the simplest first.
A third layer would be a search of existing on-line catalogs including
the CEOS IDN and other FGDC compliant catalogs. The key to making this
search user-friendlier is to develop a thesaurus of terms to translate
from user-friendly terms to catalog terms. To do this properly, a catalog
with controlled content such as the IDN is required. The information tools
team has begun work with the Working Group on Systems and Services (WGISS)
IDN task team to develop this layer. The technology for doing catalog
searches on the Internet has progressed to the point that practical implementation
methods are possible. With the demise of the DMSG tools team, hopefully
others will pick up coordination with catalog activities such as the IDN. |
Other information tools could provide additional
user-friendly features such as visualization tools or orbital tools. Visualization
tools will be useful to training in the use of satellite data. Orbital
tools would provide a potential user with a list of satellites that has
recently or will soon pass over the site of a recent disaster. WGISS task
teams could be helpful to those who want to explore and implement capabilities
of this type in the future.
A general lesson learned is that the level of effort to maintain the
DMSG website properly is much higher than was expected. Even seemingly
simple tasks, such as maintaining a current list of upcoming events or
hot events, requires constant surveillance of activities. Although simple
in nature, they require many hours each week to accomplish.
Although there were problems that kept the information tools team from
fulfilling all of its goals, many of these problems are being addressed.
User communities are working to develop more consistent, consensus terminology.
The cost and state of the art for search technology has progressed to
the point that practical Internet implementations are feasible. The work
of the Hazard Teams and the on going work of the Internatianal Charter
have established a baseline for future hazard scenarios. Hopefully, this
will encourage others to work toward achieving the identified, but unaccomplished
goals that were set under the work of the DMSG.
