Origins<\/strong><\/span><\/p>\n

Photogrammar is a site created by Yale which seeks to be a digital platform that organizes the 170,000 photographs from 1935-1946 created by the United States Farm Security Administration and Office of War Information (FSA-OWI). These photos\u00a0were originally taken as method to building trust and support for government programs for the Roosevelt Administration during the Great Depression Era. They were undertaken by the Historical Section of the Farm Security Administration as way of documenting the United States at one of its worst periods of time, as well as a way of documenting the successful administration of aid relief. \u00a0<\/span><\/p>\n

In terms of raw navigation the site starts out with a helpful welcome page that lists options for how to begin exploring the collection, finding out about its background, and for finding new experimental tools as well.<\/p>\n

The collection used to build Photogrammar includes 170,000 overall photographs. 88,000 of these are printed and placed in the office of the FSA-OWI. 77,000 of the photographs were printed by Roy Styker’s Historic Division of the Farm Security Administration. The other 11,000 come from other sources.<\/p>\n

In terms of overall collection origins, the database has grown to include six different collections. The majority of the photographs from the Farm Security Administration collection and Office of War Information collection. \u00a0\u00a0The other collections include the\u00a0Office of Emergency Management-Office of War Information Collection, the American at War Collection, the Portrait of America Collection. All these collections are overall organized and cataloged by the Library of Congress.<\/p>\n

Processes:<\/strong><\/p>\n

In terms of data processing, the Photogrammar tool had a lot of help with the fact that the Library of Congress had already digitized the photograph collection for them. The team instead had to to organize\u00a0the overall data into a database that could then sort out geographic and classification information into an easily searchable format.<\/p>\n

Presentations:<\/strong><\/p>\n

The Photogrammar team uses a variety of tools to organize and display the large amount of data that they are using.<\/p>\n

In terms of the main visualization used, the Photogrammar site uses two different versions of its mapping visualization to show the photograph locations in county and dot format.<\/p>\n

County:<\/p>\n

\"screen-shot-2016-10-03-at-1-07-56-pm\"<\/a><\/p>\n

Dot:<\/p>\n

\"screen-shot-2016-10-03-at-1-08-06-pm\"<\/a><\/p>\n

One of the tools they use is CartoDB\u00a0which is used as a database that\u00a0serves as the\u00a0primary mapping mechanism for the site due to its scalability and balance of raster and vector data formats.<\/p>\n

A second tool that they use is called Leaflet. This is used for its capabilities as an\u00a0Open-Source JavaScript Library for Mobile-Friendly Interactive Maps. The library provides an excellent general library for creating dynamic graphs.<\/p>\n

Another tool they use is a Treemap to serve as visualization of the original classification system designed by Paul Vanderbilt in 1942. 88,000 of the photographs were assigned using this classification system which uses 12 main subject headings and 13000 sub-headings which lead into various sub-sub headings.<\/p>\n

A fourth major process\/tool used on the Photogrammar site is the Metadata Dashboard. The dashboard is used as an interactive tool to display\u00a0the relationship between date, county, photographer, and subject in photographs from individual states using the already categorized metadata of the photographs.<\/p>\n","protected":false},"excerpt":{"rendered":"
