Presented by: Michael Bevans Information Manager for Digitization Imaging Guidelines and Image Archiving Practices Digitizing Plant Specimens at The New York Botanical Garden Herbarium Presented by: Michael Bevans Information Manager for Digitization

Background Imaging since 1998 Average 35,000 images per year since 2006 337,837 specimen images 27.7 TB image archive 2.5 TB remaining

Rapid Digitization Projects Plants and Fungi of the Caribbean 150,000 specimen images ADBC Plants Herbivores and Parasitoids 240,000 specimen images ADBC Bryophytes and Lichens 300,000 label images ADBC Macro Fungi 90,000 label images

3 Year Projection 780,000 images 16 TB Caribbean and Plants and Bugs 35 MB per image Bryophytes and Lichens and Macro Fungi 6 MB per image

Archive Audit GPI scans Thirteen years of legacy decisions .DCR .2TB .SID .479 TB Thirteen years of legacy decisions 2 types of RAW file formats DCR soon to be obsolete Duplicate .TIFF files Orphaned .SID files Proprietary web derivative GPI scans High resolution .TIFF files Free 2.5 TB .CR2 2.5 TB GPI scans 14.5 TB .TIFF 7.58 TB

Housekeeping .TIFF and.SID files offline All files stored on tape All legacy file formats converted to a standard format Compress large file GPI scans 200 MB per image to less than 90 MB per image FREE 19 TB GPI scans 7.5 TB .DNG 3.6 TB

Archive Policy Why archive? Archive original camera capture as .DNG Create new derivatives as technology evolves E.g. Higher resolution images online Don’t repeat digitization efforts Archive original camera capture as .DNG .DNG is an open license ‘archival’ format Preserves metadata in the file Parametric image editing Small file size

Expanded Imaging Capacity Low cost, easy to operate workstations Less than $6000 each 21 megapixel camera Copystand Lightbox Laptop Small footprint 2’x4’

Imaging Lab

Standardized Production Fixed specimen position Color bar and scale included in margin Standardized exposure Simplified file naming Barcode only v-081.1-00136401 00136401

Results of Standardization Dramatically reduced user error Fewer reshoots required Increased productivity From 53 to over 85 exposures an hour* Over 200,000 images in the last 12 months Over 4000 images by volunteers * Eliminating barcode scanning at capture produces up to 200 exposures per hour
