Item ArcGIS Pro Project Package (PPKX) Data Curation Primer(Data Curation Network, 2024) Kernik, Melinda; Work, Amy; Ranganath, Aditya; Martindale, JaimeFrom primer intro: ArcGIS Pro Project Packages are great for researchers sharing files within the same software environment (i.e. ArcGIS Pro), but the proprietary nature of the format and rapid versioning of the software makes decisions about long-term archiving difficult. ... This primer describes tips for opening and reviewing this overarching project file. Curators are encouraged to consult additional DCN Data Primers for curation checklists for component file types (like geodatabases and geotiffs).Item Minnesota Green Book Locations, 1939-1967(2023-06-15) Kernik, Melinda; Crosson, Shana; Gisselquist, John (JJ); ; kerni016@umn.edu; Kernik, MelindaDuring the Jim Crow era, many businesses in the United States refused to serve African-Americans and other individuals of color. While an increasing number of black households owned a car during this period, travelers faced inconvenience, discrimination, and danger along the road. "The Negro Motorist Green Book" (Green Book), published by Victor H. Green and Alma Green between the 1936 and 1967, compiled a list of businesses that welcomed African-Americans. Understanding where the Green Book businesses were located provides context for later urban changes, such as the construction of freeways.Item 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.
