First…. Some Terms
Metadata - Documentation of geospatial data written in a consistent manner
FGDC - Federal Geographic Data Committee
CSDGM - Content Standard for Digital Geospatial Metadata, referred to commonly as “The Standard” or “The Content Standard”
Clearinghouse - A distributed catalog of metadata
Geospatial - refers to a geographic location

Simply put, metadata is information
about your data.

This is the metadata for this.
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.

Metadata contains vital information.Metadata contains vital information.Imagine, if you will…
You are given two identical cans without labels. One contains cat food, the other contains tuna (dolphin-safe, of course).
You must choose one these cans,
and then eat the contents.

Metadata Standards
Think for a moment how hard it would be to…
… bake a cake without standard units of measurement.
… put gas into your car without standard nozzle sizes.
… plug a lamp into a socket without standard electrical outlets.

The Federal Geographic Data Committee (FGDC) was organized in 1990 under the
Office of Management and Budget to promote the coordinated use, sharing,
and dissemination of geospatial data on a national basis. The FGDC was tasked
with creating a metadata standard to meet these objectives.

"... each agency shall document all new
geospatial data it collects or produces, either
directly or indirectly, using the standard under
development by the FGDC, and make that
standardized documentation electronically

What do I use “The Workbook” for?
• It is the definitive resource for applying the FGDC Content Standard.
• However, it does not define the production rules.
• It describes element domain values, which are valid values that can be assigned to the data element.
• It provides section and element definitions.
![Page 31: ArcView Metadata Training: American Samoa James Byrne Josh Murphy NOAA Coastal Services Center July 29-30, 2003.](https://reader030.fdocuments.net/reader030/viewer/2022033106/5697bf981a28abf838c914e8/html5/thumbnails/31.jpg)
Interpreting the Metadata Workbook
A data element is a logically primitive itemof data. Data elements are the things thatyou “fill in.”
The form for the definition of a data element is:
Data element name -- definition.Type: (choice of “integer”, “real”, “text”, “date”, or “time”)Domain: (describes valid values that can be assigned)
An example of the definition of a data element is:
Abstract -- a brief narrative summary of the data set.Type: textDomain: free text
Note: Data element definitions are containedin the text of the Content Standard,
not in the graphical production rules.
![Page 32: ArcView Metadata Training: American Samoa James Byrne Josh Murphy NOAA Coastal Services Center July 29-30, 2003.](https://reader030.fdocuments.net/reader030/viewer/2022033106/5697bf981a28abf838c914e8/html5/thumbnails/32.jpg)
• It is a quick reference for production rules and structure.
Use the “Graphical Representation”for quick access.
• You will still need to use the workbook to find the definition of a particular element and its domain.

concisely sums up your data or data set.
Without metadata, your data set is
incomplete.

Writing Metadata
is not THAT bad!
• First records are the hardest.• Not all fields may need to be filled in.• Tools are available.• Training classes can be taken.• Can often be produced automatically.• Can (and should) be reviewed
for updates.
![Page 40: ArcView Metadata Training: American Samoa James Byrne Josh Murphy NOAA Coastal Services Center July 29-30, 2003.](https://reader030.fdocuments.net/reader030/viewer/2022033106/5697bf981a28abf838c914e8/html5/thumbnails/40.jpg)
Templates can help!!
• Contain information that is specific to your project or organization
• Allow you to enter and save pertinent information for use at later date
• Save time and effort!• No special tools needed!• Like any other metadata, can (and
should) be reviewed for updates.

At the right side of most of the screens will be the option to Retrieve and Save the information you have entered into the fields. This allows you to save frequently used information such as contact and similar abstracts to be used repeatedly. These are generally saved as either .dbf or .txt files in the working directory specified.
On each screen, there is a SectionHelp and a Section Example button.The Section Help button opens a window containing definitions of the metadataelements for that section. The SectionExample button provides an example of an FGDC-compliant metadata record.

DATA_QUALITY_INFORMATION
Attribute_Accuracy Attribute_Accuracy_Report: A team of field investigators participated in data verification exercises June, 1996 and December, 1996. Data validation teams consisted of personnel from Oak Ridge National Laboratory, Moss Landing Marine Laboratories, Ray L. Harris, Jr., and the Coastal Services Center. The team was equipped with a portable color laptop computer linked to a Global Positioning System (GPS). The field station runs software that supports the classified data as a raster background with the road network as a vector overlay with a simultaneous display of live GPS coordinates. Accuracy assessment points were generated with Erdas Imagine software using a stratified random sample. To make the acquisition of the field reference data more practical, a sixteen pixel buffer area around roads (i.e. 8 pixels on each side of the road) including logging trails was created. Seven thousand random points were generated within this area for the accuracy assessment. See the accuracy assessment table for results of data verification exercise.

Detailed Attribute DescriptionNot only do you have to describe your attributes but you also have to describe the values
Attribute Domains: domains are used to describe attribute values
1) Range Domain: a sequence of values- if the attribute is “water_depth” and the values are between 0 and 150, a range domain is suitable.
2) Enumerated Domain: comprised of a list of values- if the attribute is “landcover_code” and the list of values is between 1 16, then an enumerated domain should be used.
3) Codeset Domain: data values are defined by a set of codes- if the attribute is “wetland_id#” and the codes are defined in a standard or code book, then the codeset domain should be used.
4) Unrepresentable Domain: the set of data values cannot be represented- numbers assigned by software program that are meaningless
