As the repository for the majority of the state’s geologic information, the Iowa Geological Survey (IGS) manages information and/or geologic samples from more than 85,000 unique sites, as well as collections of maps, publications, and other documents. These collections summarize the research conducted by the IGS and can date back to more than a century ago. Proper preservation and metadata creation ensure the collections can be referenced for years to come. To help achieve its long-term data preservation strategy, the IGS participates in the United States Geological Survey’s National Geological and Geophysical Data Preservation Program (NGGDPP). The program provides the framework necessary to inventory and preserve collections. While the program offers a great benefit to Iowans, data are also uploaded to a National Digital Catalog where the information can be referenced nationally.
The Data Preservation program at the IGS has defined tasks that have traditionally focused on:
- Scanning well logs, geophysical logs, maps, publications, and other printed material
- Entering geologic and hydrogeologic information into databases
- Inventorying geologic collections
- Photographing rock core samples
- Creating metadata
The IGS is currently inventorying and photographing rock core samples as part of a Data Preservation effort. The images are hosted in GeoCore, a new web application that allows users to search the Rock Library’s collection for core samples of interest and view high resolution photos of each box.
