This workshop adaptation and offering in the MAGIC states is funded through an FGDC 2007 Category 1 CAP grant.
We shamelessly borrowed and incorporated existing metadata training material from the FGDC, the USGS, and the NOAA Coastal Services Center and particularly the materials of the Virginia Metadata Resource Toolkit developed by -

First the important stuff…
• Make sure that you are legally parked!
• Lunch is being provided, thanks to the workshop sponsor (XXXXXXX).
• You are on your own for breaks (sorry!)
• The rest rooms are located ???????.
Help us to educate YOU!
This should be an INTERACTIVE workshop…PLEASE feel free to ask questions, provide comments, give suggestions, and offer real world experiences along the way (don’t wait until the end!!!)
Workshop Overview
• This workshop is designed for individuals who are new to or infrequent practitioners of - metadata creation.
• It will provide you with the information you need to make decisions associated with metadata implementation in your organization.
Workshop Topics
• Section 1: What is Metadata
• Section 2: The Value of Metadata and Tips for Institutionalizing Metadata
• Section 3: Metadata Standards
• Section 4: Metadata Clearinghouses
• Section 5: Writing Metadata
What is Metadata?
• How many times have you received data from someone, and had questions about it?– Attribution– Projection / coordinate system– Scale– Accuracy– Completeness
Setting the Stage
GeospatialRefers to any data set tied
to a location on the Earth’s surface. The term “geospatial” refers to GIS, GPS, and remote sensing
products and services.
MetadataWhen referring to metadata, we assume the metadata is
well-written and fully developed.
Simply put, metadata is information
about your data.
What is Metadata?
Note: Metadata is not your actual spatial data…however, it serves as a reference for
your spatial data
This is the metadata for this.
What’s Missing?

While the card-catalog entry is a form of metadata, it does not address topics such as quality, accuracy, or scale.
Well-written geospatial metadata describes these and many more aspects of the data.

What’s missing?
This is the metadata for this.
Metadata is not “the spatial data”, but it is
a vital component
of the spatial data…
What is NOT metadata…
What is NOT metadata…
• Metadata is not “cool”
• But remember that there are many critical things in life that are not “cool” (i.e. seat belts, life jackets, fire escapes, archived data, etc.)
Metadata is not “BIG data”
(that would be mega-data…!)
What is NOT metadata…
Properly documented
data provides vital information
to interested parties.
A Component of Data
Metadata is that component of data which describes it.

Wdth – diameter of pipe in inches
Mat – material of pipe
Method – Method of data capture
Date1 – Installation date of conduit
Date2 – Date that spatial data capture was made

A Component of Data
Because metadata provides vital information about a dataset, it
should never be viewed or treated as a separate entity.

Metadata is a critical and
integral component of any complete
data set.

Summary…
• You can share metadata with others, without sharing your spatial data assets…
• Metadata can save you time (whether you are on the “giving end” or the “receiving end”).
• Metadata has always been important, HOWEVER, metadata is increasingly vital as we share more data instantaneously (server-based solutions, etc.)
Exercise - #1
Getting to Know Metadata
Choose a metadata file
Review the file and answer some basic (but important) questions!
Gain some initial familiarity with a real metadata file…
