  2. GPS/GIS Technology • New Technology for mapping bones in the quarry using high-resolution GPS equipment. • GPS data is combined with digital photos of bones in the computer. • The bones can then be seen in the computer just as they looked in the ground, but with the dirt removed.

  13. Expanded view from previous slide • Note the long ossified tendon visible in the center just above the femur. It is ¼ inch in diameter. • Femur is 50 inches long, for comparison

  14. Database Schema • Conceptual model of the structure of a database that defines the data contents and relationships • Two Broad Categories • Normalized • Un-normalized

  15. Un-Normalized • One Huge Table • Data repeated row-to-row • Data-entry errors difficult to prevent • No logical linkage between related data • Memory-intensive • Slow data access

  16. Normalized • Several smaller, interlinked tables • No data repetition • Data-entry much less error-prone • Logical linkage between related data enables advanced analysis

  17. DiGIR ProtocolDistributed Generic Information Retrieval • Taxonomic Databases Working Group (TDWG) has proposed “Darwin Schema” to facilitate dissemination of information about biological organisms • Protocol for disparate biological databases to exchange data easily

  18. DiGIR ProtocolDistributed Generic Information Retrieval • Our fully-normalized database will easily integrate with DiGIR / Darwin • Protocol still in draft stage • When it is finalized, our project will adopt it so that our data is as accessible as possible

  19. Online Fossil Database • Catalog of approximately 7000 fossil specimens, currently • Each has multiple high-resolution photographs online • Each has full GPS position data online • Each can be visualized in the quarry using GIS data • Fully searchable

  20. Conclusion • Fully-normalized database schema improves quality, availability of data • GPS / GIS / Specimen Collection integration provides wealth of data not otherwise accessible • The data are there, the possibilities are endless…
