3 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---3 What’s Metadata? Two similar paintings by Picasso sold for vastly different prices Why? One had metadata. One didn’t

4 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---4 What’s Metadata? Metadata is information about data If you had two cans without labels, which would you eat? Without a label, how would you know which was tuna and which was cat food? Cat Food? Tuna?

5 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---5 What’s Metadata? We often use metadata without even knowing it

6 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---6 What’s Metadata? A published map contains the elements of metadata… Publisher Publication date Type of map Description Spatial references Scale and accuracy

7 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---7 What’s Metadata? Metadata is a critical component of a complete data set

8 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---8 What’s Metadata? It’s data about a data set Title Scale Source Content Location Publication Access Title Scale Source Content Location Publication Access Metadata GIS files Imagery Geospatial databases GPS data GIS files Imagery Geospatial databases GPS data Data set

9 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---9 What’s Metadata? Metadata is the “stuff” to help you find and understand data — whether the data is a… list spreadsheet database CAD drawing GIS map

10 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What’s Metadata? Metadata helps those who need geospatial data find what they need and determine how to use it Geospatial data: any data with a spatial component, including maps, charts, in situ data Who Where When

11 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What’s Metadata? Metadata describes… content, quality, condition, and other characteristics about data who, what, where, why, and how of a data set

12 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What’s Metadata? Who created and maintains the data? Why were the data created? What is the content and structure of the data? Metadata answers questions…

13 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What’s Metadata? When collected? When published? Where is the geographic location? Storage location? How were the data produced? Metadata answers questions…

14 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What’s Metadata? Metadata includes information you need to… determine which data exist for a geographic location determine if a set meets your need acquire the set you identified process and use the set

15 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Metadata Is Essential for the Long Term Topic 2 Why Bother with Metadata?

16 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Bother with Metadata? You probably already have metadata in some form: Manila folders stuffed with notes Readme files Hardcopy data catalogs

17 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Bother with Metadata? Documenting data is critical to preserving its usefulness over time

18 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Bother with Metadata? Without proper documentation, no data set is complete

19 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Bother with Metadata? Data developers Data users Organizations Metadatahelps…

24 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Metadata at Its Best Topic 3 What Does Good Metadata Look Like?

25 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What Does Metadata Look Like? Metadata in the FGDC format

26 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What Does Metadata Look Like? Informative title Geographic location Sections of the standard

27 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What Does Metadata Look Like? Identification Information Originator Abstract

28 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Clearinghouses Are Necessary to Our Work Topic 4 Why Share Your Metadata?

29 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Share Your Metadata? A metadata clearinghouse is a location — typically accessed through the Internet — to search for spatial data sets

30 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata A clearinghouse is a decentralized system of Internet servers you can search Why Share Your Metadata? Servers with metadata Client

31 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Clearinghouses make metadata records easy to find Why Share Your Metadata?

32 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why clearinghouses and not web indexes? You can’t do a complete search You can only do full-text searches You can’t limit your search to particular fields Why Share Your Metadata?

33 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata You can’t perform date, numeric, geographic searches Place names don’t always relate to lat/lon You don’t have search access to existing databases Why Share Your Metadata?

34 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata The National Geospatial Data Clearinghouse has more than 100 spatial data servers with digital geographic data Why Share Your Metadata?

35 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata FGDC Geospatial Data Clearinghouse Montana State Library Natural Resource Information System GIS Nebraska Geospatial Data Clearinghouse Wisconsin Land Information Clearinghouse Why Share Your Metadata? Some specific examples:

36 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata The NGDC has the people and infrastructure to help you find out who has what geographic information Why Share Your Metadata?

37 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata The NGDC is a set of information services that use hardware, software, and telecommunications networks to provide searchable access to information Why Share Your Metadata?

38 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata The clearinghouse includes federal, state, university, and vendor participants in the United States and abroad Why Share Your Metadata?

39 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata A digital geospatial data set is the target unit of description defined in the clearinghouse Why Share Your Metadata?

40 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata You can search all or part of the community in a single session Why Share Your Metadata? x

41 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata ---41

42 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata You can define your criteria Why Share Your Metadata?

43 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata You can select a server Why Share Your Metadata?

44 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata You can view your search results Why Share Your Metadata?

45 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Help us keep metadata accurate and up to date Why Share Your Metadata?

46 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Make creating metadata part of the process of developing your data Why Share Your Metadata?

47 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata What the CSDGM Standard Is and How It Helps Us All Topic 5 Why Have a Standard?

48 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The FGDC Metadata Workbook, Version 2.0 is free and can be downloaded

49 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The standard helps you determine: if a set of geospatial data is available and fit for your use how to access and transfer the set

50 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? A standard helps to create: Common terms Common definitions Common language Common structure Access constraints Citation currentness entity attribute domain lineage Process step

51 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The standard… establishes names of data elements and compound elements defines information about values provided for data elements Access constraints Citation currentness entity attribute domain lineage

52 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The standard serves as a uniform summary description of the data set

53 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? If you’re creating metadata for the first time, the standard may seem complex Stick with it

54 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The key to using the standard… Find the fields that are pertinent to your data and your organization Build a template Use the template

55 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? Don’t create your own standard — you’ll only confuse people

56 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? The standard will benefit all of us — for years to come

57 Don’t Duck Metadata November 2000 Introducing Geospatial Metadata Why Have a Standard? Online systems rely on data being predictable in form and content Predictability is assured only when we conform to a standard
