Image 1 of 1: ‘A cycle of seven boxes connected by arrows: 1 Create or receive, 2 Appraise and select, 3 Describe (metadata), 4 Ingest into a repository, 5 Preserve, 6 Provide access, 7 Reuse and transform, which leads back to Create or receive. In the center: throughout, plan, document, watch for change.’
Image 1 of 1: ‘Three maps of Lafayette and West Lafayette with simulated household locations. Left: 120 red points at exact locations, which could identify households. Middle: the same points aggregated to census tracts, shaded from light to dark red by count, so only totals per tract are shown. Right: donut geomasking, where every point has been moved a random distance between 250 and 750 meters; one point's true location is marked with an x inside an orange ring showing the area its masked point could fall in.’
