1. FGDC CAP Kickoff Meeting Denver, CO September 28-29, 2004 1 Introduction to Metadata Lynda Wayne GeoMaxim / FGDC

2. 2 Introductions  Name  Organization  Metadata Experience  Workshop Expectations

3. 3 Objectives After the workshop, students can: develop a metadata template that uses a range of mandatory, conditional, & optional CSDGM elements effectively read and comprehend metadata make the business case for metadata discriminate between minimal and quality metadata locate and access online resources

4. 4 What IS Metadata? Data ‘reporting’ WHO created the data? WHAT is the content of the data? WHEN was it created? WHERE is it geographically? HOW was the data developed? WHY was the data developed?

5. 5 What IS Metadata? title supplemental information abstract time period author sources (file) size

6. 6 What IS Metadata? entity attributes view actual metadata record

7. 7 Let’s Make Metadata Turn to your neighbor and document the following:  Title (name)  Theme Keywords (work, play, life)  Supplemental Information

8. 8 Value of Metadata Preserves investments in geospatial data development people forget…………..people move on

9. 9 Value of Metadata Serves as a valuable resource to data use and analysis

10. 10 Projection? Attributes? Time Period? Value of Metadata Provides data consumers & stewards: a common language a context for data resources needed information about the data Albers, I think? Yes I’ll have get back to you…

11. 11 Value of Metadata Supports data management maintenance and update project status value assessment / cba project estimates deliverable and performance measures

12. 12 Value of Metadata

13. 13 Who creates metadata? Officially Federal organizations producing digital geospatial data Federally funded projects that produce digital geospatial data Morally and practically Anybody that creates digital data It’s the right thing to do!

14. 14 Why metadata? Be a part of the BIG picture Federal Geographic Data Committee (FGDC) - coordinates national geospatial data development National Spatial Data Infrastructure (NSDI) - creation and distribution of seamless national geospatial data Global Spatial Data Infrastructure (GSDI) - creation and distribution of seamless global geospatial data

15. 15 Why metadata? National Spatial Data Infrastructure Old perspective…………………. ……………………………….New perspective

16. 16 Why metadata? NSDI Framework Data - cooperatively-designed data dictionaries for seven key ‘reference’ themes Elevation and Bathymetry Hydrography Geodetic Control Cadastral Transportation Governmental Units Orthoimagery

17. 17 Why metadata? NSDI Geospatial Data Clearinghouse - international network of metadata distribution ‘nodes’ FGDC EROS ESRI NRCS NOAA CSC ALASKA GDC international GINA AGDC ASGDC Anchorage state / local national query available metadata records user internet Clearinghouse nodes

18. 18 Why metadata? NSDI Geospatial One Stop metadata and links to data webmapping services data acquisition plans data category communities …..fast tracking the NSDI

19. 19 Why Metadata? FGDC Geospatial One-stop National Map data access coordination national state local private metadata services community policies standards partnerships

20. 20 How Do I Create Metadata? the metadata gospel… It’s not pretty It’s not easy But sure is thorough….. CSDGMCSDGM ISOISO

21. 21 CSDGM 1. Identification Information General bibliographic information including: title, originator, data contact, status, date, time period of content, abstract, purpose, keywords, geographic location 2. Data Quality Information Lineage and data assessments sources, process methods, accuracy, data processing contact

22. 22 CSDGM 3. Spatial Data Organization Data format: vector, point, raster 4. Spatial Reference Information Coordinate system parameters: horizontal / vertical coordinate system, projection, datum

23. 23 CSDGM 5. Entity and Attribute Information Database design entities, attributes, domains, description of data values 6. Distribution Information How to acquire the data distribution contact, available formats, online distribution website, costs

24. 24 CSDGM 7.Metadata Reference Information General information about the metadata record itself metadata contact, metadata standard used, metadata creation date, metadata review date

60. 60 Making Metadata Part of the Process New tools enable us to better integrate metadata creation into the data development process

61. 61 Making Metadata Part of the Process If metadata were collected throughout the data process… 1.more accurate (no guessing) 2.more details 3.better decision-making. metadata

62. 62 Making Metadata Part of the Process But what can I do to better incorporate metadata into the data development process?

63. 63 Make the business case: preserve data investments limit data liability manage data resources find new data resources easier data transfer more efficient data distribution step one: build adminstrative support

64. 64 Emphasize individual benefits: reduce workload..in the long term field fewer data inquiries document personal contributions step two: build technical support

65. 65 Support your staff include in job descriptions & performance measures provide staff support tools training step two: build technical support

66. 66 For each common data type:  identify pertinent fields  populate fixed fields  standardized language  distribution methods  standards used  build source and contact libraries step three: create organizational templates

67. 67  map fields to the work flow  establish and assign responsibilities  technicians - lineage  analyst - process methodology  field scientists - accuracy assessments  IT managers - tools, collection, management step four: distribute the effort

68. 68 step four: distribute the effort Data Planning: Section 1: Identification Info  title  originator  purpose  content time period  theme keywords  abstract

69. 69 step four: distribute the effort Data Planning Section 3: Data Organization  Indirect Spatial Reference FIPS codes, county monikers, etc  Object-type point, vector, or raster

71. 71 step four: distribute the effort Data Processing Section 2: Data Quality  completeness report missing or omitted data  positional accuracy digitize rms error, GPS triangulation, survey/photogrammetry/IP method

72. 72 step four: distribute the effort Data Processing Section 2: Data Quality  lineage data set source files data compilation process maps photos dbases GIS

73. 73 step four: distribute the effort Data Analysis Section 2: Data Quality  attribute accuracy field checks, cross-checks, statistical analyses  lineage data analysis process

75. 75 step four: distribute the effort Data Analysis Section 7: Metadata Reference metadata contact and dates

76. 76 Managers Can WRITE metadata  data planning fields titleabstract purpose geographic extentkeywords and many more… and manage the effort  metadata coordination  metadata enforcement step five: lead by example

77. 77 Establish Policies:  mandate use of standards and templates  develop boilerplate metadata deliverable language for data contractors  require units to publish their metadata  publish metadata SOP to document policies and procedures step six: policies and procedures
