This document summarizes a geospatial metadata and spatial data workshop. The workshop included presentations on metadata standards and application profiles, demonstrations of metadata tools like the Geodoc Metadata Editor, and hands-on sessions with metadata tools and repositories. The goal of the workshop was to promote best practices for documenting and sharing geospatial data through metadata.

Geospatial Metadata Workshop
- 1. Geospatial Metadata and Spatial Data Workshop
- 2. Workshop Programme PRESENTATION SESSION: Background information Metadata, standards and application profiles UK Academic Geospatial Metadata Application Profile, Version 2 (UK AGMAP 2) and guidelines Geodoc Metadata Editor tool, Go-Geo! portal and other resources ShareGeo Open spatial data repository Look at current and future activities REFRESHMENTS (15 - 30 minutes) DEMONSTRATION/HANDS-ON SESSION: Geodoc Metadata Editor tool, Go-Geo! portal and ShareGeo Open spatial data repository
- 3. Background three decades of GIS and spatial data capture technology an eclectic range of academic disciplines using GIS as a research and teaching tool considerable cost and time invested in spatial data creation *2006 spatial data audit at 4 universities: +500 dataset files, 100s of orphan datasets Requires a spatial data management, discovery and sharing solution delivered through portal technology and metadata .
- 4. So what is METADATA ? The word appears to be of Greek and Latin origin…… but metadata represents something completely different…… Photographic Images copyright: Jupiter Images 2006
- 5. Photographic Images copyright: Jupiter Images 2006 and it’s not sun and holiday
- 6. Represents a documented and ordered summary of information that describes something, in this case, a spatial dataset. Provides the What, Where, When and Why of a dataset, Ownership and Contact details and Access and Use conditions. Think of metadata as a recipe for making beer….. What are the ingredients? What are the brewing steps? Who sells the ingredients or W here can you buy them? Purpose of making beer? Metadata (data describing data) Photographic Images copyright: Jupiter Images 2006 An incentive to encourage metadata creation?
- 7. Where is the study area represented in the data? When were the data collected? What is the dataset’s purpose? spatial reference system? spatial accuracy? type of application? processes or algorithms used? Who supplies the data? What do these polygons represent? What attribute information is associated with these polygons? So why metadata? Can you tell me from these files…..
- 8. What do these SOILCLASS values mean? What does this attribute mean?
- 9. These questions can be answered in one metadata record
- 10. The relevance of geospatial metadata Useful for local data management Dataset Creator/ User Metadata Record Spatial dataset Directory Spatial Datasets Metadata Directory
- 11. Geoportal : an interface to run searches on the internet to locate geographical resources, and to discover, harvest and publish metadata records representing spatial data and geo services. A geoportal enables users to search and discover geospatial metadata using geographic location (co-ordinates and place name) free text date resource type Geoportal Metadata Record Spatial Datasets and Geo-services Useful to discover spatial data and services via metadata published on a Geoportal

- 14. Other benefits: data protection Photographic Images copyright: Jupiter Images 2006
- 15. protects investments of time and cost dedicated to dataset creation and development; maintains an inventory of datasets to reduce time required to re-assess existing datasets for new and future applications; ensures integrity of existing and new datasets using metadata as a tracking mechanism to monitor changes and edits to datasets; reduces and minimises the disruptive effects of staff turnover; eliminates or reduces the risk of redundancy in dataset collection; accidental deletion of dataset files.
- 16. Intellectual Property Rights (IPR) residual licensed data rights for derived data liability fears concerns over data quality (data creator and user) privacy and security time and cost for data delivery data transformation and harmonisation (scale, positional accuracy, projections, formats) legacy data time and cost to anonymise data for release time and cost for metadata record updates, especially descriptive level metadata performance, maintenance and enhancements of portals and repositories data archiving data and software warehousing issues long-term commitment and investment in the infrastructure revisions to standards confusion about standards compliance and which standard to use Still issues though!
- 17. Metadata standards provide precise specifications; enforce and ensure consistency and interoperability; define and describe metadata entities and data elements; classify and group relevant metadata elements with entities; assign structure and conditions (obligations, data type, domain).
- 18. Dublin Core (ISO 15836) Dublin Core: 15 elements to facilitate simple resource discovery in a networked environment (e.g. internet or library) Photographic Images copyright: Jupiter Images 2006
- 19. Geospatial metadata standards Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM) introduced in mid 1990s for documenting spatial datasets. ISO 19115 Metadata Standard for Geographic Information was ratified in 2003 and supersedes FGDC. Geospatial metadata standards are critical for supporting metadata creation and…………………………

- 22. Geospatial Metadata Application Profiles ISO 19115 standard has too many elements (300+)
- 23. * An application profile is derived from a standard and represents a reduction of the number of entities and elements. * It should include the core element set of a standard to support interoperability across the wider geospatial community ( Discovery level metadata). * Should include elements for Descriptive level metadata? * It can be extended to include elements which are best suited for a working group’s specific applications. Example: The Biological Data Profile (BDP) An approved profile with additional elements to allow for documenting biological information such as taxonomy , m ethodology and analytical tools . http://www.flickr.com/photos/f10n4/186861991/
