Best Practices for Geospatial Data Transfer for Digital PreservationDecember 2011
The GeoMAPP project's primary goal is to ensure the long term preservation of archived geospatial content. In order to preserve geospatial content, the GeoMAPP team explored processes, techniques, and tecnologies to transfer geospatial data to an archival organization with state-wide preservation responsibility for geospatial data. This paper offers guidance on planning, preparation, and execution of dataset transfers to the archival organization, and highlights the data transfer experiences from the GeoMAPP partner states. The paper also includes an archiving project roadmap that will assist organizations exploring geoarchiving in planning their data transfer projects, suggestions for GIS and archival cross-organizational collaboration for orientation and knowledge transfer, network and infrastruture considerations in preparation for transferring files, naming and file organizational recommendations, and tips on tools for packaging and validating data file transfers. The paper also provides a role-based summary of the data transfer tasks for geospatial contributors and the archival recipients. Be sure to refer to the appendices for project planning checklists and numerous resources to support the data transfer planning, preparation, and execution activities.

Emerging Trends in Content Packaging for Geospatial DataDecember 2011
An individual geospatial data resource may be composed of a complex, inter-related set of data files as well as metadata and other supporting file objects, all of which need to be arranged in a certain fashion in order to be understood by the software and the humans that are involved in the exchange, management, and use of the data. This report characterizes the role that content packaging is coming to play with regard to geospatial data management and access; documents emerging content package types that have appeared in the geospatial community; and explores preservation challenges that may arise when these packages are expected to persist over time or when the packaging process itself results in changes to packaged data.
Archival Challenges Associated with the Esri Personal Geodatabase and File Geodatabase FormatsDecember 2011
Spatial databases play a prominent role in geospatial data production and management, storing a range of data types including geographic features, attribute information, satellite and aerial imagery, surface modeling data, and survey measurements. In addition to storing data, some types of spatial databases can also model the relationships between data, handle data validation, and support complex data models, versioning, and multi-user editing, all of which greatly improve data integrity and analysis capabilities. One area of focus for GeoMAPP has been understanding the long-term sustainability of Esri Geodatabase content in an archival context, and whether it would be better to convert these databases to open formats or retain them in a particular Esri Geodatabase format. This report provides an initial assessment of the preservation challenges associated with the Personal Geodatabase and File Geodatabase formats.

Geospatial Data File Formats Reference Guide (Microsoft Excel)July 2011
Electronic file format support is a fundamental challenge in the long-term preservation of digital materials. This issue is especially relevant for geospatial datasets that are created, shared, and stored in many different formats, many of which are proprietary to a specific vendor and/or software application. Geospatial data is primarily comprised of raster data, made up of a two dimensional array of equally sized cells where each cell holds a single attribute value and location coordinates, or vector data, represented as points, lines, and polygons. In addition to the fundamental geographic information, many datasets also include underlying tables of data that further elaborate the geographic elements, such as population counts, income values, average property values, demographic information, or identifying information for individual features such as name, address, etc. Then all of this data may further be wrapped within an encompassing database that enables relationships and analysis across the datasets. Many of the geospatial formats are manifested as numerous files in a variety of file types. All of these aspects pose challenges to GIS professionals and to archivists both today and in the future.
This spreadsheet provides a quick reference of some of the common geospatial raster and vector dataset types, and can serve as a tool to identify geospatial format types based on file extensions.

Preserving Geospatial Datasets and Geospatial MetadataUtilizing Geospatial Metadata to Support Data Preservation Practices
Metadata associated with geospatial datasets can provide a rich insight into the technical details about the dataset it is describing while also providing information about the 'who', 'what', 'when', 'where', 'why', and 'how' to explain the dataset's purpose and utility. When thoughtfully populated, geospatial metadata can be a critical resource for understanding and managing geospatial data for current and future GIS practitioners and those trying to preserve the geospatial data.
GeoMAPP has prepared a checklist that identifies key geospatial metadata fields that can be beneficial to the long term preservation of the GIS datasets. While fully compliant, richly completed full geospatial metadata records should always be the preferred standard for GIS data creators, the above checklist highlights metadata fields that deserve special focus to be thoughtfully populated by GIS data creators, and more thoroughly reviewed by GIS clearinghouses to benefit long-term GIS data preservation, access, and use.

Utah's Electronic Records Management Business Case
This electronic records management (ERM) strategy is a collection of definitions, distinctions, best practices, and industry standards that will enable the efficient use of Utah state government resources and continued confidence in the state’s records management stewardship.
In the summer and fall of 2008, the GeoMAPP team conducted several state specific and national surveys to identify geospatial creation and archiving trends among state and local agencies in North Carolina as well as among state archives and members of the national geospatial community.
The GeoMAPP team developed two similar surveys, one targeting state government archivists and records managers, and another distributed to state Geographic Information Officers (GIOs) and other state government GIS leaders. The surveys featured some questions unique to the target audience and others that were common across surveys for ease of comparison. Below are the survey questions and resultant raw data.
