Archives Conservation Discussion Group 2011: Digitization and Its Effect on Conservation Treatment Decisions: How Has Wide-Spread Digitizing of Collections Changed Our Approach to Treatment?

In line with this year’s AIC theme: ETHOS, LOGOS, PATHOS: ethical principles and critical thinking in conservation, The Archives Conservation Discussion Group 2011 examined the impact of providing digital collections in museums and libraries, and their conservation implications. Presentations and a subsequent discussion covered topics such as: How conservators are balancing ethical concerns, especially as dictated by the AIC Code of Ethics, with increased demand from digital projects. How conservators are keeping pace with large-scale or fast-paced digitizing projects, while maintaining standards. And the impact of limiting access to original materials by providing digital surrogates and its effect on treatment decisions

Digitized Astronomical Photographic Archives as Large Area Sky Survey of Large Amount of Astronomical Data

We report here on an investigation of astronomical plate archives and tests of the scanning devices for digitization of archival astronomical plates. These archives represent huge database of historical astronomical data, astrometric, photometric, and spectroscopic, with many applications in modern astrophysics

Creating Three-Sixty Objects for Marist Archives Using Open Source JQuery Reel

[Excerpt] In this article I will look into some of the recent 3D digitization projects and highlight numerous technological and financial challenges that would be familiar to many small and medium sized archives. I will further propose jQuery Reel, an open source three-sixty player as a viable alternative to 3D modeling and discuss the workflow we employed at Marist Archives

Guidance for benthic habitat mapping: an aerial photographic approach

This document, Guidance for Benthic Habitat Mapping: An Aerial Photographic Approach, describes proven technology that can be applied in an operational manner by state-level scientists and resource managers. This information is based on the experience gained by NOAA Coastal Services Center staff and state-level cooperators in the production of a series of benthic habitat data sets in Delaware, Florida, Maine, Massachusetts, New York, Rhode Island, the Virgin Islands, and Washington, as well as during Center-sponsored workshops on coral remote sensing and seagrass and aquatic habitat assessment. (PDF contains 39 pages) The original benthic habitat document, NOAA Coastal Change Analysis Program (C-CAP): Guidance for Regional Implementation (Dobson et al.), was published by the Department of Commerce in 1995. That document summarized procedures that were to be used by scientists throughout the United States to develop consistent and reliable coastal land cover and benthic habitat information. Advances in technology and new methodologies for generating these data created the need for this updated report, which builds upon the foundation of its predecessor

An examination of automatic video retrieval technology on access to the contents of an historical video archive

Purpose – This paper aims to provide an initial understanding of the constraints that historical video collections pose to video retrieval technology and the potential that online access offers to both archive and users. Design/methodology/approach – A small and unique collection of videos on customs and folklore was used as a case study. Multiple methods were employed to investigate the effectiveness of technology and the modality of user access. Automatic keyframe extraction was tested on the visual content while the audio stream was used for automatic classification of speech and music clips. The user access (search vs browse) was assessed in a controlled user evaluation. A focus group and a survey provided insight on the actual use of the analogue archive. The results of these multiple studies were then compared and integrated (triangulation). Findings – The amateur material challenged automatic techniques for video and audio indexing, thus suggesting that the technology must be tested against the material before deciding on a digitisation strategy. Two user interaction modalities, browsing vs searching, were tested in a user evaluation. Results show users preferred searching, but browsing becomes essential when the search engine fails in matching query and indexed words. Browsing was also valued for serendipitous discovery; however the organisation of the archive was judged cryptic and therefore of limited use. This indicates that the categorisation of an online archive should be thought of in terms of users who might not understand the current classification. The focus group and the survey showed clearly the advantage of online access even when the quality of the video surrogate is poor. The evidence gathered suggests that the creation of a digital version of a video archive requires a rethinking of the collection in terms of the new medium: a new archive should be specially designed to exploit the potential that the digital medium offers. Similarly, users' needs have to be considered before designing the digital library interface, as needs are likely to be different from those imagined. Originality/value – This paper is the first attempt to understand the advantages offered and limitations held by video retrieval technology for small video archives like those often found in special collections

Image processing mini manual

The intent is to provide an introduction to the image processing capabilities available at the Langley Research Center (LaRC) Central Scientific Computing Complex (CSCC). Various image processing software components are described. Information is given concerning the use of these components in the Data Visualization and Animation Laboratory at LaRC
