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

2 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”.

3 Introducing Geospatial Metadata ---3 Don’t Duck Metadata Outline: Introduction to metadata. Metadata Content Schema

4 Introducing Geospatial Metadata ---4 Don’t Duck Metadata 1.What is metadata? 2.Why is it important? 3.Executive Order 12906 4.The FGDC Geospatial Data Clearinghouse TOPIC 1: Introduction to Metadata

5 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)

6 Introducing Geospatial Metadata ---6 Don’t Duck Metadata Needed for appropriate use of data Needed for appropriate management of data. Metadata is an important component of spatial data 1.2: Why is it important?

7 Introducing Geospatial Metadata ---7 Don’t Duck Metadata examples: Spatial Referencing Systems Entity and Attribute Classification Data Collection Technique Metadata is needed for appropriate use of data

8 Introducing Geospatial Metadata ---8 Don’t Duck Metadata Spatial Referencing Systems

9 Introducing Geospatial Metadata ---9 Don’t Duck Metadata Data reflect the purposes of the creator! Entity and Attribute Classification Wetland delineation as defined by investment bankers Wetland delineation as defined by conservationists

10 Introducing Geospatial Metadata ---10 Don’t Duck Metadata Data lineage and Data accuracy. Without metadata, how can a user identify the source of this error?

11 Introducing Geospatial Metadata ---11 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

12 Introducing Geospatial Metadata ---12 Don’t Duck Metadata 1.3: Executive Order 12906 FGDC metadata, and the National Spatial Data Infrastructure.

13 Introducing Geospatial Metadata ---13 Don’t Duck Metadata FGDC Metadata Federal Geographic Data Committee Executive Order 12906 mandates that all Federal agencies and organizations receiving federal funds must document all geospatial data using the FGDC metadata format

14 Introducing Geospatial Metadata ---14 Don’t Duck Metadata Single-use data: Data are seen as a means to an end.

15 Introducing Geospatial Metadata ---15 Don’t Duck Metadata Multiple-use data: Data are seen as central

16 Introducing Geospatial Metadata ---16 Don’t Duck Metadata Spatial data collection, and acquisition are major obstacles of spatial analysis.

17 Introducing Geospatial Metadata ---17 Don’t Duck Metadata Search, Suitability decisions Subsequent users need information Metadata is mandated by EO 12906 to facilitate the NSDI Metadata is the foundation of the NSDI

18 Introducing Geospatial Metadata ---18 Don’t Duck Metadata 1.4: The FGDC Geospatial Data Clearinghouse

19 Introducing Geospatial Metadata ---19 Don’t Duck Metadata

20 Introducing Geospatial Metadata ---20 Don’t Duck Metadata

21 Introducing Geospatial Metadata ---21 Don’t Duck Metadata

22 Introducing Geospatial Metadata ---22 Don’t Duck Metadata

23 Introducing Geospatial Metadata ---23 Don’t Duck Metadata

24 Introducing Geospatial Metadata ---24 Don’t Duck Metadata

25 Introducing Geospatial Metadata ---25 Don’t Duck Metadata The data set is then distributed in its entirety!

26 Introducing Geospatial Metadata ---26 Don’t Duck Metadata FGDC compliant metadata: A record of all the information needed to effectively use a data set for analysis. The only manner in which to contribute to the National Spatial Data Infrastructure

27 Introducing Geospatial Metadata ---27 Don’t Duck Metadata 1.The Content Standard for Digital Geospatial Metadata 2.Metadata Content 3.Exercise: The Metadata Content Questionnaire! TOPIC 2: Metadata Content

28 Introducing Geospatial Metadata ---28 Don’t Duck Metadata 2.1 The Content Standard for Digital Geospatial Metadata The CSDGM specifies needed information and a strict structure!

29 Introducing Geospatial Metadata ---29 Don’t Duck Metadata The structure of the FGDC metadata standard can be confusing... at first.

30 Introducing Geospatial Metadata ---30 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.

31 Introducing Geospatial Metadata ---31 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!

32 Introducing Geospatial Metadata ---32 Don’t Duck Metadata 2.2 Metadata Content The structure is simply the means by which the content is searched, displayed, and used!

33 Introducing Geospatial Metadata ---33 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

34 Introducing Geospatial Metadata ---34 Don’t Duck Metadata Bits of information Abstract Purpose Attribute Accuracy Report Grid Coordinate System Name Entity Type Definition Distribution Liability Metadata Contact

35 Introducing Geospatial Metadata ---35 Don’t Duck Metadata 2.2 Exercise: The Metadata Content Questionnaire

36 Introducing Geospatial Metadata ---36 Don’t Duck Metadata Topic 3: Schema 1.Sections 2.Data Elements and Compound Elements 3.The Graphical Representation 4.Exercise: Navigating the Graphical Representation... Writing FGDC metadata! 5.Validating metadata

37 Introducing Geospatial Metadata ---37 Don’t Duck Metadata 3.1: Sections Our “bits of information” are grouped into 7 main sections, and 3 supporting sections.

38 Introducing Geospatial Metadata ---38 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.

39 Introducing Geospatial Metadata ---39 Don’t Duck Metadata 3.3: The Graphical Representation The Graphical Representation is an invaluable tool to help navigate the standard!

40 Introducing Geospatial Metadata ---40 Don’t Duck Metadata Graphical Representation of Elements Sections, compound elements, and data elements are represented by these symbols.

41 Introducing Geospatial Metadata ---41 Don’t Duck Metadata Conditional usage Element conditionality is color coded.

42 Introducing Geospatial Metadata ---42 Don’t Duck Metadata Repeatability Some elements are repeatable.

43 Introducing Geospatial Metadata ---43 Don’t Duck Metadata Navigation Sometimes the standard requires that you omit one section in favor of another.

44 Introducing Geospatial Metadata ---44 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.

45 Introducing Geospatial Metadata ---45 Don’t Duck Metadata From “bits of information” to FGDC Metadata! In this exercise, we will take our content, which looks like this.....

46 Introducing Geospatial Metadata ---46 Don’t Duck Metadata and make FGDC metadata, which looks like this....... From “bits of information” to FGDC Metadata!

47 Introducing Geospatial Metadata ---47 Don’t Duck Metadata Writing Metadata!
