  2. Title: Grave Reform in Modern China

    Contributors:

    Summary: Grave Reform in Modern China is a digital humanities initiative based at Stanford that is building an interactive spatial and textual analysis platform to examine the phenomenon of grave relocation in modern China, a campaign that has led to the exhumation and reburial of 10 million corpses in the past decade alone, and has transformed China’s graveyards into sites of acute personal, social, political, and economic contestation.

  5. Title: Mapping Inequality

    Contributors:

    Summary: Mapping Inequality is a digital humanities project that allows users to explore the history of redlining in the United States through an aggregation of records from the National Archives and Records Administration (NARA). It uses the Home Owners’ Loan Corporation’s records, dating between 1935 and 1940, to create an interactive map that reveals the ways city neighborhoods were rated according to their perceived desirability and risk levels for granting home loans. The site allows users to explore this information in different forms including the original digitized records, full transcriptions of the records, and excerpts that highlight significant details selected from the records by the project designers. The goal of Mapping Inequality is to call attention to the ways in which the practice of redlining contributed to the ongoing reality of racial inequality in the United States. Transcription is ongoing, and more information will be available on the site over time.

  6. Title: Home Owners' Loan Corporation Graded Neighborhoods, United States, 1935 [GeoJSON]

    Contributors:

    Summary: GeoJSON containing digitized polygons showing graded neighborhoods as designated by the Home Owners' Loan Corporation (HOLC) in 1935. Polygons were digitized from georeferenced HOLC Maps. The HOLC was established in 1933 by the U.S Congress to refinance mortgages in default and prevent foreclosures. In 1935 they created residential security maps for 239 cities to indicate the level of security for real-estate investments. The maps were graded such as the newest areas, which were considered desirable for lending received a "Type A" grade. These areas were primarily wealthy suburbs on the outskirts of town. Still Desirable neighborhoods were given a "Type B" grade and older neighborhoods were given a "Type C" grade and considered Declining. Lastly "Type D" neighborhoods were regarded as most risky for mortgage lending. This dataset is part of the Mapping Inequality project. Mapping Inequality brings one of the country's most important archives to the public. HOLC's documents contain a wealth of information about how government officials, lenders, and real estate interests surveyed and ensured the economic health of American cities. And with the help of ongoing research, we continue to learn at what cost such measures were realized University of Richmond. Digital Scholarship Lab. (2021).

  8. Title: Dry Nitrogen Deposition: San Francisco Bay Area, California, 2007

    Contributors:

    Summary: This raster dataset depicts dry nitrogen deposition for the nine county San Francisco Bay Area Region, California. Dry nitrogen deposition is the input of reactive nitrogen from the atmosphere into the biosphere as dry deposition, or acidic gases and particles. An overabundance of nitrogen in the atmosphere and environment has deleterious effects on the biosphere. The source data was produced by the Center for Conservation Biology at the University of California, Riverside (UCR) and is based on a nitrogen deposition model data developed by the UCR College of Engineering Center for Environmental Research and Technology (CE-CERT). Text values from the dry nitrogen deposition model were processed to provide the values stored in this raster. The model used here is total annual deposition and based on data from calendar year 2002. These data are considered useful in studying the effect of nitrogen deposition on aspects of complex biological systems. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships. The Conservation Lands Network GIS Database is the primary output of the Project. The data depicts the spatially explicit CLN that is recommended for the nine county San Francisco Bay Area Region, California.

  9. Title: Total Nitrogen Deposition: San Francisco Bay Area, California, 2007

    Contributors:

    Summary: This raster dataset depicts a geography of nitrogen deposition for the nine county San Francisco Bay Area Region, California. Nitrogen deposition is the input of reactive nitrogen from the atmosphere into the biosphere as wet and dry deposition, either acidic gases and particles or acidic rain, fog and snow, respectively. An overabundance of nitrogen in the atmosphere and environment has deleterious effects on the biosphere. The source data was produced by the Center for Conservation Biology at the University of California, Riverside (UCR) and is based on a nitrogen deposition model data developed by the UCR College of Engineering Center for Environmental Research and Technology (CE-CERT). Raster values from both dry and wet nitrogen deposition models were added to provide the values stored in this raster. It represents total annual deposition of all forms of nitrogen for the calendar year 2002. These data are considered useful in studying the effect of nitrogen deposition on aspects of complex biological systems. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships.

All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, built-up areas, selected buildings, Borough boundaries, parks, docks, and more. Relief is shown by hachures. Includes location tape. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

  16. Title: PLSS Lincoln County, WI 2024

    Contributors:

    Summary: This data represents public land survey system (PLSS ) corners for Lincoln County, Wisconsin in 2024. [The E4 PLSS database, part of a multi-year effort, was created as a sub-project of the greater Version 8 Statewide Parcel Map Database Project (V8 Project), a collaboration between the Wisconsin Land Information Program, the State Cartographer’s Office, and county data contributors. More information about the Statewide Parcel Map Initiative can be found here.The E8 database contains a collection of all uniquely identifiable local-level PLSS data available in digital format, and aggregates that data into a standardized schema and format. It also includes section, quarter-section, and quarter-quarter-section level polygons. The construction of the PLSS corner locations contained within the database relies on the local level coordinate information. This unique aspect of the database, allows for an accurate representation of the on-the-ground location of the PLSS corners.Please complete the feedback survey form.Schema documentation can be found here.]
