INTRODUCTION
Geoscientific Geospatial data is the foundation to
analyzing and understanding natural resources,
environment processes, impacts, hazards and stress such
as climate change.

Disparate efforts in the region:
-large amounts of geoscience research and data
-priceless
-adequately digitized , catalogued or duplicated
-seldom in cooperated into GIS system

OIP uses an array of GIS tools to produce digital
geospatial systems and maps

SOPAC OIP now has an ongoing committment to data
rescue, collation, storage, data cataloguing and digitisation.
KEY PRINCIPLES OF DATA RESCUE
Data to be stored as image files into medias, that
can regularly renewed to prevent subsequent loss
of data due to deterioration of medium.

Data already on computer compatible media
should be routinely migrated to storage facilities
that conform to changing technologies and enable
easy access; and

Data should be key-entered in a form that can be
use for analyses

OBJECTIVES:
System that assists in the management ,
preservation/ archiving SOPAC's Marine
and Oceanographic data and its metadata.

System that gives a public presence of
SOPAC Marine data and promote SOPAC
OIP products and work

System that allows the sharing of
information between different organisation
for better decision making in the region

STANDARD

ISO 19115 - International Geospatial Metadata standard
(Federal Geographic Data Committee (FGDC) Content, Standard for Digital Geospatial Metadata
(CSDGM), officially, known as FGDC-STD-001-1998 or The Dublin Core Metadata Element)

What Does Metadata Do?
An important reason for creating descriptive metadata is to facilitate discovery of relevant
information. In addition to resource discovery, metadata can help organize electronic
resources, facilitate interoperability and legacy resource integration, provide digital,
identification, and support archiving and preservation.
Metadata is key to ensuring that resources will survive and continue to be
accessible into the future.

METADATA STANDARD : ISO 19115
DESCRIPTIVE METADATA
Describes a resource for the purposes such as discovery and identification. It can include elements such as tittle, abstrct , author and keywords
METADATA STANDARD : ISO 19115
Structural metadata:
Indicates how compound objects are put together, for example, how pages are ordered to form chapter or how it was digitised and reformed to usable
formats.
Metadata identifier
METADATA STANDARD : ISO 19115
Administrative metadata provides information to help manage a resource, such as when and how it was created, filet ype and other technical information, and
who can access it. There are several subsets of administrative data; two that
sometimes are listed as separate metadata types are:
− Rights management meta-data, which deals with intellectual property rights,
and
− Preservation metadata, which contains information needed to archive and preserve a resource.

SUMMARY
SOPAC GEONETWORK is an online catalogue of
marine scientific information and associated information
Information collected from surveys and ocean
observations conducted in the Pacific Region
BENEFITS – public presence of Scientist work, use of
simple visuals to coomunicate information, e quick
reference for more detailed enquiry, Wider stakeholders
know of marine data existence, (Dataset and metadata)
archived and preserved , provides a focal point for
marine data request in the region.
