Introduction
•
Implementing ISO 19115 - Metadata
–
–
Have built tools that let people create ISO
metadata using ArcCatalog
• ArcCatalog is one of a suite of desktop
products provided with ArcGIS
ISO metadata can be published on the
Internet using the Geography Network
Background: What is
ArcCatalog?
•
A tool for exploring and managing
geographic data
–
–
–
File-based data on disk in many formats
Design and implement spatial databases in
an enterprise RDBMS
Access vector, image, metadata services
on an ArcIMS Internet servers
Browse for data
Preview geography
View an analyze tables
Change properties and attributes
Explore metadata
Design goals for metadata in
ArcCatalog
•
Make it easy to create and use
metadata
–
–
Create editors that are easy to use
Create and update metadata automatically
with a dataset’s current properties
Design goals for metadata in
ArcCatalog
•
Support FGDC and ISO metadata
content standards out-of-the-box
–
•
Support other standards through
customization
Support metadata for everything
–
Geographic data, non-spatial files, folders,
databases, etc.
Design goals for metadata in
ArcCatalog
•
Metadata is part of the data
–
–
•
Travels with the data when copied, moved,
renamed, or exported
Doesn’t get lost
Achieve our goals using open, flexible,
industry standard technology
–
Metadata stored in XML format
ISO metadata tools in ArcCatalog
•
•
•
•
•
Editor for typing information
Stylesheets for viewing
Synchronizer for updating
automatically
Importers and exporters
Translator from one standard to
another
ISO metadata editor
•
•
•
•
New wizard-based editor designed for
the average person
Elements are introduced by plain
language
Navigate with Next and Back buttons or
go directly to a page using the TOC
Handles core elements as defined by
19115
ISO metadata editor
ISO metadata editor
•
Red asterisks indicate mandatory
elements
–
–
–
Which pages have mandatory elements
Which elements on a page are mandatory
Disappear when information is provided
ISO stylesheets
•
Stylesheets map metadata elements in
XML to HTML for better viewing
–
•
Similar to SQL queries—select data and
define how to show it
Display the same metadata record in
many ways with different stylesheets
ISO stylesheets
ISO synchronizer
•
•
Automates much
of the work for
metadata
collection and
maintenance
Vector and raster
information,
spatial reference,
etc.
Automatically senses and records properties
ArcIMS
Services
Files
Demo
Author and publish metadata

•
Scientist generates a dataset
Metadata is automatically generated
Scientist augments metadata using
editor
Publishes data as image map service
Publishes metadata to Geography
Network
What is the Geography
Network?
•
•
•
Builds on the NSDI / GSDI clearinghouse
A collection of geographic information
managed by a librarian

What is the Geography Network?
•
When searching for data you find:
–
•
Ordering information, ftp download sites,
WMS services
Geography Network emphasizes variety
of immediately available services
–
–
Live maps, data streaming, zip & ship
datasets, GIS services—positioning, and
solutions—flood risk mapping
Support enterprise GIS, eGovernment,
eCommerce
Searching the Geography
Network
•
Can use many search clients
HTML or Java

Issues in implementing ISO
19115
•
To adequately describe data we need to
use many ISO standards, e.g.
–
–
•
19110: Feature cataloguing methodology
19111: Spatial referencing by coordinates
No clear way to integrate information
defined by multiple parts of ISO 19xxx
standards
–
If there isn’t a standard XML DTD, the
information isn’t interoperable
