Introduction: From data to information


GEO aim of achieving
interoperability
of existing
and new systems that
provide

essential
environmental
observations

and
information


Data streaming from in
-
situ and remote sensing
sensors

(Sensor Web),
models

(Model Web)
offers a huge potential to generate a wide
portfolio of on
-
demand and near
real time
products
.


In the GEO Work Plan these activities are elements of GEO Task IN
-
05 "
GEOSS

Design and Interoperability".

Task

Policy and Science Vision for GEOSS


How is knowledge discovered? (D.
Maidment
)


Deduction from existing knowledge


Experiment in a laboratory


Observation of the natural environment


Observation is the heart of
GEOSS
, Crafting
geoinformation
, the art and science of
Earth Observation (D.
Maidment
)


Each decision we make influences the state of the planet, it is changing, we have
to
understand the planet and the impacts of those influences
. (
P.Colohan
)


Our ability to
exchange data
brings the imperative to bring all the data forward,
for observing the planet. (
P.Colohan
)


Raison d'être for GEO/
GEOSS

is
data sharing
(
A.
Lauthenbacher
)


Local to Region to Global

integration, interoperability (D.
Maidment
)


Sensor Web Enablement allows us to pull data together (D.
Maidment
)


International standards, OGC process can make common languages (D.
Maidment
)


Build momentum around key datasets, key communities of practice, help them
realize the
benefits of the standards
.


Different countries have different ways to define things.
Semantic integration
can
help build the ways of conveying information and defining things in a common
way.

Policy and Science Vision for GEOSS


GEOSS

is a voluntary effort, not a mandate. Three principles (
P.Colohan
):


Science based
decision making


Open access

to data and information


International
cooperation



A very generic approach is very difficult due to heterogeneity of data,
models, decisions, etc.


Environmental policy challenges:


1. Carbon, quantify and regionally disaggregate to figure out
sources/absorption and retention.


2. Extremes


“Water is the delivery vehicle of climate change” How are things
changing? water, floods, droughts, freezing, heat waves, sea level, etc. These
all affect businesses and commercial interests


3. Food security


Seasons changing, global crop production


Full realization of
GEOSS

seems distant, but we need to take steps in right
direction now.

Current GEOSS architecture and users


GEOSS

Common Infrastructure


Operational
GCI

is in place


Usability issues and challenges


Expressed interest in sensor webs / model webs



Each building a Community of Practice within science/application area


All looking for variety of data sources/types


Common needs for data discovery, search, access services


With focus on
SBAs
, risk of creating new stovepipes?


SBAs

have particular interest but
GEOSS

architecture intended to provide
common capabilities



The extent of current use is unclear


Users appear to be consumers and providers of data and services

About the data


With regard to openness, who supports it? What is the
business model?


Organizations (such as OGC) that include govt. and
industry partners promote openness


Incentives come from top down


leaders of int’l
organizations


Commercial involvement in GEOSS


as providers and
users of products?


Agriculture given as potential area for data exchange


Efforts to take in socioeconomic data?


AIP tasks mentioned as mechanism to identify needs for
these data


Classification of disasters by socioeconomic characteristics

Sensor Web Session


Aims:


to explore techniques to integrate in situ and satellite
observations, and model forecasts in a sensor web
architecture, and


to look at ways to enable users to leverage sensor
webs to develop 'on
-
demand' products.


Missed opportunity to talk about (J.
Maso
)


Sensors that auto
-
declare themselves in the web?


How to go from millions of individual observations to
a structured information?: from observations to
products.

Sensor


Model Integration and users

Focus on Sensor


Model


How do you enable better
discovery of workflows that
match a given suite of user
requirements


i.e. pattern match between
everything from sensor types to
decision
-
support requirements

Focus on the User


How do you deliver to the user
the required products and
services with the requisite
level of customization

User
-
Requirement Registry (URR)


Collect, store, publish (Hans
-
Peter):


Requirements: what to do, who to do it


Lexicons, controlled vocabularies; essential variables


Integrated into the
GEOSS

Semantics Registry


Connect Earth observations to societal benefits using
value chains


With the
URR

you can:


Identify value
-
adding business processes; with crowd
-
sourced input and validation


Analyze goals: gaps; prioritization of users, data &
processes; relevance of data

Model Web Initiative


Vision: dynamic web of models, integrated
with databases and websites


consultative
infrastructure for asking the
URR

“what if”
questions (
S.
Nativi
)



e.g. How will climate change affect infection rate
of dengue fever in Vietnam?


Huge amounts of
data
available


Numerous
models
& modeling frameworks


Links/interfaces needed for connecting
vocabularies
,
brokers, knowledge bases, business processes


how
to combine what is needed?

The session was about tools to create future products

Vision for Integrated Modeling


Time is as important as space (R. Moore)


Natural events & “black swans” difficult to model (R.
Moore)


Deep Water Horizon


Volcanic ash


Climate, energy, water, health issues


Depends on trust in framework by users and public (R.
Moore)


Barriers to progress: awareness, confidence, availability,
skill base, little R&D program, little uptake among target
groups


Products are the results of chaining models (composed by
processes) and data (also sensor)

Model Web


Include modeling/process capabilities as discoverable and
usable
GEOSS

resources


Challenges


Manage heterogeneity of resources


Agreed definition of “model” representation


High
-
performance computing


Scalable, distributed


Long
-
term access; standardization
vs

virtualization


Model integration and brokering between different platforms


Recognize that
GEOSS

has different user types, and Model Web
addresses some of them


Work out a short term roadmap for the Model Web,
including effective show cases


Considering low hanging fruits


Integrating existing components

Interoperability and Resource Discovery


Two directions:


GEOWOW



EU FP7 Project


Applies the Discovery and Access Broker


semantically enriched search,
results ranking results


Linked Data


Government data portals moving this direction


Semantically enriching catalogs will improve discovery


Authentication, Single
-
Sign
-
on (
SSO
)


Will benefit providers to track accesses (aggregated)


OpenID

& SAML2: Need implementations & testing



GEOSS

users; where are the citizens? What are our
GEOSS

users,
and then how can we package the product?


citizen user is hard to predict.


Helper App are important to facilitate the use of data once
discovered
