Capacity Building Report


based on AIP6




Lucia Lovison,

Ben Buford

and Bart De Lathouwer

Introduction

This report wants to contribute to clarifying the capabilities and services provided by the GEOSS
Infrastructure for whoever wants or needs to familiarize
him

or
her

with it. This documen
t is a work in
progress and aims to give an overview of the GEOSS Inf
rastructure and how to become part of it.

The document reflect
s

only a partial view of what is mostly “work in progress” made possible by several
people who are dedicated to the advancement of knowledge and skills and should be recognized at any
time.

What is GEOSS?


T

he Global Earth Observation System of Systems (GEOSS) is being built by the Group on Earth
Observations (GEO) on the basis a ten
-
year project that will come

to a renewal in January 2014.
Other
definitions can be found in the main
web site
http://www.earthobservations.org/geoss.shtml

wher
e
GEOSS is defined as
a series of “decision
-
support tools to a variety of users.”

Sometimes, GEOSS is
defined as “system of system” but

we prefer not to use this expression that a layperson is not familiar
with.

Generally, GEOSS

is a set
of technologies, standards and specifications

for collecting
and
exchanging
geospatial data and metadata

that are
proposed, discussed, tested,
become gr
adually
accepted and operative by group of geospatial technical and later administrative people.

The underline assumption is that

through a network provided by
internet
--

data, especially geospatial
data and metadata
through web services
will be made
available to a variety of users.

In this report, we’ll also assume that there are the four “types” of GEOSS subjects: Data Providers
,
GEOSS Users
, Data

Acquirer and Identity Providers (IDP).

Of course, depending on the business model
that one entity will
adopt, there are also many other subjects that we’ll not consider at this point.

Data Provider

GEOSS User

Ben

Data Acquirer



definition


related to mobile user who wants to both user the GEOSS Infrastructure but
also prov
ide geospatial data
acquired
through its mobile device(s) and upload them to the cloud (for
example)

or to any other server
.

Ben

Identity Provider



definition



Ben

will propose a definition
.
Lucia

will review
and check

it with
Steve
Browdy.

The GEOSS I
nfrastructure can accommodate many types of architecture: from a middleware to a broker
to an API to be downloadable to a mobile device.

Usually a middleware, proprietary or open
-
source, is associated with a specific social benefit area, while
a federated

system is associated with organizational or an enterprise perspective.


How do
es

one register?

You can register your web service either by yourself through the GEOSS
Component and Service
Registry
(
http://geossregistries.info/
) or
through GCI broker.

Bart: will add info

on additional ways to register to the GEOSS Infrastructure based on the
previous

AIPs
Engineering Report
s
.

Ben will check if there is some issue form point of view of

a
mobile User (
Data
Acquirer
)
. It will be
responsibility of the
User
Acquirer

to either develop as API the data collection and metadata generation
or
to register

data and metadata services.

This is

a starting point. Please refer

For issues on
big analytics, please see WPS and OGC Working Group activity (

).

Making an example (ask Matt

to contribute later on
).

How does one make its services (WMS, WFS,
WCS or others) discoverable to others?

Once registered, you can record your service into the FGDC Status Checker
(
http://registry.fgdc.gov/statuschecker
/documentation.php#service
-
types
), so to make sure that your
service is discoverable by other GEOSS web services. However, the FGDC Status Checker seems to
support only the FGDC service checker, so if you have CWS developed with Geo Network, you need to
im
plement a FGDC service checker
profile or

d
eploy an

atom feed to the
FGDC
service checker
.
