Digital Documerica Data: Exploring Environmental Photography from the 1970s

Derived data from the Documerica Photographic corpus, which contains 15,911 photographic images created by the U.S. Environmental Protection Agency (EPA). The archives contains the following files: documerica-metadata.csv: Metadata downloaded directly from the United States National Archives. One row per photograph. documerica_mhm.tar: Zipped archive of the color-corrected digitized images. See referenced paper below for details on the color correction method used. documerica-gpt4-caption.csv: Automatically generated captions using the gpt-4-turbo-2024-04-09 with the instructions "Provide a detailed plain-text description of the objects, activities, people, background and/or composition of this photograph". documerica-siglip-embed.json: Embedding generated from the multimodal siglip-base-patch16-224 model. The datasets are linked by the field nid, which corresponds to the unique numeric ID provided by the National Archives. See the included publications and the Digital Documerica website for more information about the corpus and why it was created.
