Current Activities
Industry Outreach:
Archives and Libraries act in conjunction with geospatial users in government to meet with ESRI and discuss need for published or open formats.
Appraisal:
Continuing to explore the appraisal issues around geospatial data for long-term preservation.
Have completed the reworking the "Appraisal and Selection of Geospatial Data" white paper prepared by Steve Morris for the Library of Congress in February 2011. The paper has been reviewed for comment by the full NDSA Content WG and will be shared with the NDSA Coordination Group for final review in late July with a public release planned in Sept. 2013. Latest version (version 6).
The group will continue to leverage work being done by the FGDC Users/Historical Data Working Group. The group is reviewing the U/HDWG paper on "Guidance on the Selection and Appraisal of Geospatial Content of Enduring Value" which is currently under review by the FGDC Coordination Group. As a future action, the group may adapt this FGDC report and recast it as an NDSA report.
The group will continue to build on GeoMAPP appraisal efforts.
Collection Development Policies/Records Acquisition Policies/Records Retention Policies:
Members will share their policy documents with the group for comparison purposes. One possible outcome could be an NDSA "standard" collection policy document template and an NDSA "standard" records acquistion template (if different?).
Spatial Data Infrastructure:
Leverage SDI activities happening at all levels of government to benefit the long-term preservation of geospatial information of value to the nation. From the FGDC web site:
"Consistent means to share geographic data among all users could produce significant savings for data collection and use and enhance decision making. Executive Order 12906calls for the establishment of the National Spatial Data Infrastructure defined as the technologies, policies, and people necessary to promote sharing of geospatial data throughout all levels of government, the private and non-profit sectors, and the academic community.
The goal of this Infrastructure is to reduce duplication of effort among agencies, improve quality and reduce costs related to geographic information, to make geographic data more accessible to the public, to increase the benefits of using available data, and to establish key partnerships with states, counties, cities, tribal nations, academia and the private sector to increase data availability."
Proprietary vs. open formats:
Discuss the challenges and opportunities with dealing with different formats. Prepare case studies on format issues or on particular formats. Address "emerging" "current" and "waning" formats. Explore format "openness" (For background information reference blog posts here and the perspective of the new Esri DC Development Center here). Build on GeoMAPP format work and Library of Congress Sustainability of Digital Formats work.
Rights and Access:
Explore copyright and other rights issues that challenge the access to and preservation of Geospatial Data: (a) copyright, licensing and legal implications of language such as indemnification/hold harmless clauses in data distribution agreements; (b) administrative metadata for dealing with access rights (c) Costs/fees for obtaining local public geospatial data and implications for archiving (i.e. continually purchase new versions based on retention schedule?)
Technical Best Practices
Work to Compose and Disseminate Technical Best Practices for geospatial preservation: (a)File formats, naming conventions and best practices; (b) Export feature classes out of geodatabases and archive as shapefiles?; (c) re-name files for archiving purposes, but retain link (via database?) back to original file from original data producer? (d) share organizational workflow demonstrations with the group.
Explore the possibility of a future geospatial preservation Wikipedia article. Some of the work the group did when considering the FGDC Geospatial Platform may be relevant (content, limitations, risks, etc.). See also http://blogs.loc.gov/digitalpreservation/2014/01/wikipedia-the-go-to-source-for-information-about-digital-preservation/
Metadata:
Document ISO standards, preservation standards, preservation-based metadata formats as they relate to long-term stewardship. Actively participate in standardization activities through OGC, ISO, FGDC and organizations such as ASPRS etc.
State GIS Clearinghouse Issues:
Continue to explore the role of state GIS Clearinghouses and their relationship with local data providers and the details regarding the data transfer between the two: (a) acquisition of data (by the clearinghouse) on specific schedules; (b) data sharing agreements between the two entities; (c) definition of framework layers and those preserved vs. not preserved (appraisal process) in an eventual archive; (d) metadata and minimum documentation required by both clearinghouse and archive
At-Risk Data Issues:
Explore challenges related to Orphan works and leverage existing efforts such as the IEEE Group on Earth Observations Purge Alerts and the ICSU/CODATA Data at Risk Inventory to identify stewards for at-risk and endangered data.
- Coordination Challenges
- Capacity Challenges
- Organizational/Resource Challenges: use as structure for case studies
- Records Retention Approach
- Collections Development Approach
- Orphaned Works Challenges
- Organizational/Resource Challenges: use as structure for case studies
- Records Retention Approach (NARA, North Carolina, Kentucky)
- Collections Development Approach (Montana, Wisconsin, university libraries)
- Organizational/Resource Challenges: use as structure for case studies
Goal is to use the descriptions of how these organizational approaches work to show their pluses and minuses in terms of identifying geospatial data and bringing that data into the repository for long-term preservation and access. This approach will enable other organizations to recognize the approach that they use and see their own strengths and weaknesses.
Appears that we have an A1 and A2 approach to the scheduling method as Kentucky's approach is not the same as NARA nor North Carolina.
FGDC may have a CAP Grant for Geo-archiving Business plan development which could be used to accomplish this goal.

Draft Definition of At-Risk Geospatial Content
The geospatial content group has defined at-risk data as that which they take in, collect and/or maintain based on an established collecting policy, schedule, or agreed upon appraisal decisions, recognizing overlap between federal, state and local government
We define "data at risk" in this context as scientific data which are not in a format that permits full electronic access to the information which they contain. Such data may be inherently non-digital (e.g. handwritten or photographic), on near-obsolete digital media (such as magnetic tapes) or insufficiently described (lacking meta-data). Some born-digital data can also be considered "at risk" if they cannot be ingested into managed databases because they lack adequate formatting or metadata. Data which are regarded as unuseable tend to be regarded as useless, and then risk being destroyed. Most of the non-electronic data in question pre-date the digital era, and where they complement more modern ones by offering a much longer time-base they are essential, sometimes vital, for studies of long-term trends
