Introducing Geospatial Metadata ---1 Don’t Duck Metadata Introducing Geospatial Metadata A Metadata Workshop

Introducing Geospatial Metadata ---2 Don’t Duck Metadata Workshop objectives Introduction to metadata, its importance, role, and the FGDC metadata standard. This workshop is designed to be a hands-on session where you will work with your own data. By the end of the workshop, you should have 1) a sample record that documents your data, and 2) ideas for how to make metadata work for your project. All participants should finish the workshop by getting involved in the “metadata movement”.

Introducing Geospatial Metadata ---5 Don’t Duck Metadata 1.1: What is Metadata? Components of Data Metadata is the component of data that describes it. (data about data)

Introducing Geospatial Metadata Don’t Duck Metadata Metadata is also needed for appropriate management of data. P rotect data from being lost. P reserve data over time. P romote good science. P rovides the foundation of a National Spatial Data Infrastructure

Introducing Geospatial Metadata Don’t Duck Metadata 1.3: Executive Order FGDC metadata, and the National Spatial Data Infrastructure.

Introducing Geospatial Metadata Don’t Duck Metadata FGDC Metadata Federal Geographic Data Committee Executive Order mandates that all Federal agencies and organizations receiving federal funds must document all geospatial data using the FGDC metadata format

Introducing Geospatial Metadata Don’t Duck Metadata Single-use data: Data are seen as a means to an end.

Introducing Geospatial Metadata Don’t Duck Metadata Multiple-use data: Data are seen as central

Introducing Geospatial Metadata Don’t Duck Metadata Spatial data collection, and acquisition are major obstacles of spatial analysis.

Introducing Geospatial Metadata Don’t Duck Metadata 2.1 The Content Standard for Digital Geospatial Metadata The CSDGM specifies needed information and a strict structure!

Introducing Geospatial Metadata Don’t Duck Metadata The structure of the FGDC metadata standard can be confusing... at first.

Introducing Geospatial Metadata Don’t Duck Metadata The structure of the FGDC metadata standard is a strength! Contribution to NSDI needs only a text editor Machine-readable structure enables sgml and xml encoding Structure enables extensibility Shared elements enable data-type-level documentation The FGDC standard is flexible enough to document multiple types of spatial data.

Introducing Geospatial Metadata Don’t Duck Metadata Data producers write Metadata! Metadata consists of important information about the data. Most of the information required by the CSDGM is dealt with during data production Once the scientist, or data producer, is familiar with the standard, writing metadata is easy!

Introducing Geospatial Metadata Don’t Duck Metadata 2.2 Metadata Content The structure is simply the means by which the content is searched, displayed, and used!

Introducing Geospatial Metadata Don’t Duck Metadata The CSDGM divides your metadata into “bits of information” that can be manipulated, shared, searched and displayed. The CSDGM builds a Bridge between data producers, and computers. metadata search and display

Introducing Geospatial Metadata Don’t Duck Metadata 3.1: Sections Our “bits of information” are grouped into 7 main sections, and 3 supporting sections.

Introducing Geospatial Metadata Don’t Duck Metadata 3.2: Data Elements and Compound Elements Within each section, data elements (bits of information) can be further grouped into compound elements.

Introducing Geospatial Metadata Don’t Duck Metadata 3.3: The Graphical Representation The Graphical Representation is an invaluable tool to help navigate the standard!

Introducing Geospatial Metadata Don’t Duck Metadata Graphical Representation of Elements Sections, compound elements, and data elements are represented by these symbols.

Introducing Geospatial Metadata Don’t Duck Metadata Conditional usage Element conditionality is color coded.

Introducing Geospatial Metadata Don’t Duck Metadata Repeatability Some elements are repeatable.

Introducing Geospatial Metadata Don’t Duck Metadata Navigation Sometimes the standard requires that you omit one section in favor of another.

Introducing Geospatial Metadata Don’t Duck Metadata 3.4: Exercise: Navigating the Content Standard for Digital Geospatial Metadata. In this exercise, we will “plug” our metadata content into the appropriate FGDC structure.

Introducing Geospatial Metadata Don’t Duck Metadata From “bits of information” to FGDC Metadata! In this exercise, we will take our content, which looks like this.....

Introducing Geospatial Metadata Don’t Duck Metadata and make FGDC metadata, which looks like this From “bits of information” to FGDC Metadata!
