Issues

Issues

  • Numerical Data – OCR is Difficult

  • Needed New Interface (didn’t fit into the existing system as neatly as the historical reports)

  • Browsing Capability for 1987 and 1982 is Complete

  • Searching Will be Added (OCR on the table headers)

  • Census of Agriculture (1987, 1982, 1978, 1974, 1969, 1964,1959, 1954, 1945, 1935 and 1925)


Digitization process

Digitization Process

  • Outsourcing the scanning

  • Text scanned as 600 dpi bitonal (I bit) images

  • Grey-scale pages scanned at 300 dpi (8 bit) images

  • Color pages scanned as 300 dpi (24 bit) images


Post scanning work and progress to date

Post-scanning work and Progress to Date

  • PDFs made for each table

  • PDFs are OCR’d to allow searching

  • 1987, 1982, 1978, and 1974 have been scanned

  • PDF creation complete for 1987 and 1982. It’s underway for 1978

  • 1969 is currently being scanned
