GIS, or Geographic Information Systems, store information tied to a location. The archival preservation of GIS data is an ongoing challenge.

Chapter 7: Historical Building Information Model (BIM)+: Sharing, Preserving and Reusing Architectural Design Data by Dr. JuHyun Lee and Dr. Ning Gu

Chapter 7 of Partners for Preservation is ‘Historical Building Information Model (BIM)+: Sharing, Preserving and Reusing Architectural Design Data’ by Dr. JuHyun Lee and Dr. Ning Gu. The final chapter in Part II: The physical world: objects, art, and architecture, this chapter addresses the challenges of digital records created to represent physical structures. I picked the image above because I love the contrast between the type of house plans you could order from a catalog a century ago and the way design plans exist today. ... 

The CODATA Mission: Preserving Scientific Data for the Future

The North Jetty near the Mouth of the Columbia River 05/1973This session was part of The Memory of the World in the Digital Age: Digitization and Preservation conference and aimed to describe the initiatives of the Data at Risk Task Group (DARTG), part of the Committee on Data for Science and Technology (CODATA), a body of the International Council for Science.

The goal is to preserve scientific data that is in danger of loss because they are not in modern electronic formats, or have particularly short shelf-life. DARTG is seeking out sources of such data worldwide, knowing that many are irreplaceable for research into the long-term trends that occur in the natural world. ... 

Creative Funding for Text-Mining and Visualization Project

The Hip-Hop word count project on caught my eye because it seems to be a really interesting new model for funding a digital humanities project. You can watch the video below – but the core of the project tackles assorted metadata from 40,000 rap songs from 1979 to the present including stats about each song (word count, syllables, education level, etc), individual words, artist location and date. This information aims to become a public online almanac fueled by visualizations. ... 

National Archives Transitions to Flickr Commons Membership

Even with the recent announcement that the Flickr Commons is not currently accepting new applications, there are clearly still applications being processed. NARA has been on Flickr since February of 2009 and loaded 49 sets of images. As announced in a recent press release, on the first of February 2010 Flickr flipped the switch and all the images in the The U.S. National Archives' photostream was shifted over into the Commons.

Dipity: Easy Hosted Timelines

Dipity LogoI discovered Dipity via the Reuters article An open-source timeline of the virtual world. The article discusses the creation of a Virtual Worlds Timeline on the Dipity website. Dipity lets anyone create an account and start building timelines. In the case of the Virtual Worlds Timeline, the creator chose to permit others to collaborate on the timeline. Dipity also provides four ways of viewing any timeline: a classic left to right scrolling view, a flipbook, a list and a map. ... 

Book Review: Past Time, Past Place: GIS for History

Past Time, Past Place: GIS for History consists mainly of 11 case studies of geographic information systems being applied to the study of history. It includes a nice sprinkling of full color maps and images and a 20 page glossary of GIS terms. Each case study includes a list of articles and other resources for further reading.

The book begins with an introduction by the editor, Anne Kelly Knowles. This chapter explains the basics of using GIS to study history, as well as giving an overview of how the book is organized. ... 

GIS and Geospatial Data Preservation: Research Resources

I found these websites while doing research for a paper on the selection and appraisal of geospatial data and geographic information systems (GIS). I hope these links might be useful for others doing similar research.

CIESIN – Center for International Earth Science Information Network at Columbia University, especially Guide to Managing Geospatial Electronic Records (USA)

CUGIR – Cornell University Geospatial Information Repository, especially Collection Development Policy (USA) ... 

The Edges of the GIS Electronic Record

I spent a good chunk of the end of my fall semester writing a paper ultimately titled “Digital Geospatial Records: Challenges of Selection and Appraisal”. I learned a lot – especially with the help of archivists out there on the cutting edge who are trying to find answers to these problems. I plan on a number of posts with various ideas from my paper.

To start off, I want to consider the topic of defining the electronic record in the context of GIS. One of the things I found most interesting in my research was the fact that defining exactly what a single electronic record consists of is perhaps one of the most challenging steps. ...
