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

GIS, Access, Archives and Daydreams

Today in my Information Structure class, our topic was Entity Relationship Modeling. While this is a technique that I have used frequently over the many years I have been designing Oracle databases, it was interesting to see a slightly different spin on the ideas. The second half of class was an exercise to take a stab (as a class) at coming up with a preliminary data model for a mythical genealogical database system. ... 

Session 510: Digital History and Digital Collections (aka, a fan letter for Roy and Dan)

There were lots of interesting ideas in the talks given by Dan Cohen and Roy Rosenzweig during their SAA session Archives Seminar: Possibilities and Problems of Digital History and Digital Collections (session 510).

Two big ideas were discussed: the first about historians and their relationship to internet archiving and the second about using the internet to create collections around significant events. These are not the same thing. ... 

SAA 2006 Session 103: “X” Marks the Spot: Archiving GIS Databases – Part III

With the famous Hitchhiker’s Guide to the Galaxy quote of “Don’t Panic!”, James Henderson of the Maine State Archives gave an overview of how they have approached archiving GIS data in his presentation “Managing GIS in the Digital Archives” (the third presentation of the ‘X Marks the Spot’ panel). His basic point is that there is no time to wait for the perfect alignment of resources and research – GIS data is being lost every day, so they had to do what they could as soon as possible to stop the loss. ... 

SAA 2006 Session 103: “X” Marks the Spot: Archiving GIS Databases – Part II

Richard Marciano of the SALT interdisciplinary lab (Sustainable Archives & Library Technologies) at the San Diego Supercomputer Center delivered a presentation titled “Research Issues Related to Preservation of Geospatial Electronic Records” – the 2nd topic in the ‘X’ Marks the Spot session.

He focuses on research Issues related to preservation of geospatial electronic records. While not an archivist, he is a member of SAA. As a person coming to archival studies with a strong background in software development, I took great comfort in his discussion of their being a great future for IT and archivists to work together on topics such as this. ... 

SAA 2006 Session 103: “X” Marks the Spot: Archiving GIS Databases – Part I

‘X’ Marks the Spot was a fantastic first session for me at the SAA conference. I have had a facination with GIS (Geographic Information Systems) for a long time. I love the layers of information. I love the fact that you can represent information in a way that often makes you realize new things just from seeing it on a map.

Since my write-ups of each panelist is fairly long, I will put each in a separate post. ...
