NIST Scientific and Technical Document Database

  

A sample of the data contained in this database is available via anonymous ftp at sequoyah.ncsl.nist.gov in the files sd20-README.txt and sd20.tar [307K].

The images contain a very rich set of graphic elements such as graphs, tables, equations, two column text, maps, pictures, footnotes, annotations, and arrays of such elements. No ground truthing or original typesetting information is available.

The images contain predominantly machine printed English, although three French and German documents are included.

Major features of the database include:

• 104 articles, books, journals
• 23,468 full-page binary images
• high resolution 15.75 dots per mm (400 dpi)
• 4 compact disks each containing about 500 Mb
• updated CCITT IV Compression Source Code
• a structural statistics file for each image
• page rotation estimates
• software utilities

NIST Special Database 20 is available as a four 5.25 inch CD-ROM set .

System requirements: CD-ROM drive with software to read ISO-9660 format.

Price: $90.00. Special pricing for multiple copies available. Call for details.
