  1. NPGS Georeference Project Stephanie L. Greene, Prosser, WA

  2. Project History • How it was done • Results • Incorporating new data into GRIN • MS Access data review form

  3. Project History • Worldwide push to mine information in biological collections using biodiversity informatics. Essential ingredient: latitude/longitude • Chapman, A.D. and J. Wieczorek (eds). 2006. Guide to Best • Practices for Georeferencing. Copenhagen: Global Biodiversity Information Facility • 2007 Robert Hijman and colleagues receive World Bank Grant to georeference CGIAR germplasm collections. 5 NPGS sites and NP contribute $45,000 to have NPGS accessions included. • GRIN data sent to IRRI , Philippines in 2008.

  4. Method • 108, 000 accessions where srctype=collected and lat.long.= null were examined • 150,000 accessions having lat. longs. were verified to country level and as not falling into ocean • Locality and habitat fields were reviewed and locality cleaned up i.e. information was moved to appropriate fields • Distance and direction designations in Locality were standardized • Lat. longs. were georeferenced using protocols outlined in Guide to Best Practices for Georeferencing (see me for copy) • Extensive annotations were made regarding data clean up, discrepancies and source of estimated lat.longs.

  5. Results • IRRI returned a dataset that contains lat.long., uncertainty, corrections, annotations (see Final Report for details) • 81,828 accessions received lat. long. values (76%) • 1647 acc. mapped to wrong country, 1822 fell into the ocean- these received corrected map coordinates (~3% error) • 74% georeferenced to locality level, 17%, admin 1 level, 9% admin 2 level

  6. Number of records by site

  7. GRIN incorporation • Data has not been incorporated, but IRRI table is linked to habitat table • GRIN habitat table has been modified to accommodate new fields (lat., long., uncertainty) • For new data, uncertainty can be calculated using the georeference calculator (www.manisnet.org/gc.html) • Our task as curators: Review and incorporate data into GRIN • Esther Peregrine has developed an MS Access form that allows curators to review, edit, annotate and place new data into a prep form for uploading into GRIN

  8. Let’s hold questions/discussion until after Esther’s presentation We will also be having hands-on training of the MS Form on Wednesday evening Further training- web seminar My question to you: Can we agree on a date to complete this project?
