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 BestPractices 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.

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.

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

Number of records by site

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

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?
