    A Collaborative Vision for Spatial Scholarship Across the CIC
    (2012) Bidney, Marcy; Mattke, Ryan; Weessies, Kathleen
    This paper identified geospatial data as a long term, interdisciplinary need that would necessitate increasingly complex infrastructures to manage. The authors concluded that these infrastructures would likely be prohibitively expensive for each CIC library to maintain individually, and they proposed collaborative solutions for long term management of geospatial resources.

    Ephemeral Geodata: An Impending Digital Dark Age
    (Journal of Map & Geography Libraries, 2024-09-12) Majewicz, Karen; Martindale, Jaime; Kernik, Melinda; Mattke, Ryan
    Despite the unprecedented rate of geospatial data (“geodata”) generation, we are paradoxically creating a potential “dark age” in geospatial knowledge due to a failure to archive it. In the 20th century, map libraries systematically collected and preserved government-issued maps. However, many have not expanded to include digital formats, which have replaced paper maps in most domains. Compounding this issue is the prevailing practice among government data providers to continuously update public data without adequately preserving previous iterations, thus overwriting the historical record. Consequently, a pronounced gap has emerged in the availability of geospatial information, spanning from the end of the paper map era to the recent past. If unaddressed, this gap is poised to widen, severely impeding future longitudinal research. This paper assesses the current and predicted availability of state and local geographic information across various locations and time periods, analyzing academic map collections and public geodata. Central to our argument is the role of academic libraries in bridging this gap by collecting and preserving yesterday’s geodata. We advocate for libraries to ensure that historical geodata will be accessible for future scholars.

    Mapping Prejudice: The Map Library as a Hub for Community Co-Creation and Social Change
    (Taylor & Francis, 2022-06-14) Mattke, Ryan; Delegard, Kirsten; Leebaw, Danya
    The John R. Borchert Map Library was the ideal incubator for an experiment that has changed how a wide range of people are thinking about structural racism and the history of race in American urban environments. Mapping Prejudice used a cartographic visualization of racial covenants as the intellectual nexus of a project that transcended disciplinary boundaries and invited community members into cutting-edge research work. The Map Library provided the physical space, resources, and geospatial expertise necessary for community-driven mapping work. It also served as an intersectional hub necessary for this transformative research initiative, illustrating the synergies between map librarianship and other disciplines. The work depended on the unique contributions of the map librarian: project management; experience networking with researchers, campus departments, and community groups; and knowledge of best practices surrounding data management, curation, and reuse. This article explains how Mapping Prejudice changed academic scholarship and public understandings by engaging volunteers in meaningful research. It concludes by providing a description of future directions for this project and calls on librarians to lead more work of this kind. The example of Mapping Prejudice suggests ways that map librarians can be leading new modes of inclusive, equitable and community-responsive research.

    Placing Data in the Land of 10,000 Lakes: Navigating the History and Future of Geospatial Data Production, Stewardship, and Archiving in Minnesota
    (2016-03-15) Dyke, Kevin R.; Mattke, Ryan; Kne, Len; Rounds, Shawn
    The goal in this article is to provide background and offer a framework for developing a program to archive the state of Minnesota’s spatial data at the University of Minnesota. It begins with a review of the literature on geospatial data archiving, preservation, and curation, and goes on to make a business case for archiving geospatial data. It next provides a brief history of Geographic Information Systems (GIS) in Minnesota, beginning in the late 1960s with the University of Minnesota’s Center for Urban and Regional Affairs’ (CURA) Minnesota Land Management Information System (MLMIS) project through the establishment of the Minnesota Geospatial Information Office (MnGeo) in 2009. After providing this historical context, this article builds upon existing organizational infrastructure in Minnesota to sketch a preliminary framework for archiving the state’s spatial data.

    Racial Covenants in Hennepin County
    (2020-11-25) Ehrman-Solberg, Kevin; Petersen, Penny; Mills, Marguerite; Delegard, Kirsten; Mattke, Ryan; mapprejudice@umn.edu; Corey, Michael; University of Minnesota Mapping Prejudice Project
    This data was compiled by the Mapping Prejudice Project and shows the location of racial covenants recorded in Hennepin County between 1910 and 1955. Racial covenants were legal clauses embedded in property records that restricted ownership and occupancy of land parcels based on race. These covenants dramatically reshaped the demographic landscape of Hennepin County in the first half of the twentieth century. In 1948, the United States Supreme Court ruled racial covenants to be legally unenforceable in the Shelly v. Kraemer decision. Racial covenants continued to be inserted into property records, however, prompting the Minnesota state legislature to outlaw the recording of new racial covenants in 1953. The same legislative body made covenants illegal in 1962. The practice was formally ended nationally with the passage of the Fair Housing Act in 1968.

    A Spatial Collaboration: Building a Multi-Institution Geospatial Data Discovery Portal
    (2017) Blake, Mara; Majewicz, Karen; Mattke, Ryan; Weessies, Kathleen
    As academic education and research increasingly take advantage of geospatial data and methodologies, we see a corresponding exponential growth in the number of available geospatial resources in the form of GIS datasets and scanned historical maps. However, users can experience difficulty finding these resources due to the unconnected multitude of platforms and clearinghouses that host them. Additionally, the resources are not always well described with web semantic metadata that facilitates discovery. In response to this challenge, The Big Ten Academic Alliance Geospatial Data Project began in 2015 to provide discoverability, facilitate access, and connect scholars to geospatial resources. Our project leverages a multi-institutional collaboration and open source technologies to improve discovery for users of geospatial data and scanned maps. We outline collaborative workflows and strategies for a successful multi-institution collaboration.

    Twin Cities Historical Surface Waters Based on Original Public Land Survey Maps, 1848 - 1858
    (2017-09-13) Graves, Richard; Strong, Richard; Mattke, Ryan; Kne, Len; Shepard, Coleman; Kernik, Melinda; stron081@umn.edu; Strong, Richard B.
    These shapefiles of lakes, streams, wetlands, river bottoms, and the Mississippi River represent the hydrological landscape of Minneapolis and St. Paul as recorded in the original public land survey conducted between 1848 and 1858. The features were digitized from scanned, georeferenced 1:24000 maps during the 2017 Faculty Research Sprint held at the University of Minnesota. Many streams and other hydrologic features that were present in the Twin Cities at the time of the original land survey were channelized, covered, or filled during the late 1800's. These features, however, still function as water conduits within the hydrology systems of urban water and have immense importance to the water regime in the Twin Cities. This data was generated as part of a larger "Lost Waters" research project - aiming to create a visible, physical representation of these waters in the current urban landscape.
