DESCRIPTION:Street-level photographs of New York City from the early 1900s 
 show how people used to live\, from their clothes and vehicles to their st
 ores and advertisements. Several open source projects have mapped archival
  “street view” images of New York\, relying on various collections of 
 photos with locations. These interactives\, primarily built with Mapbox GL
  JS\, are instructive when visualizing a newly-digitized archive\, in this
  case a set of over 60\,000 photos from the construction of the NYC subway
  between 1900 and 1950 with approximate coordinates.\n\n1. [“Street View
 \, Then & Now: New York City's Fifth Avenue”](http://publicdomain.nypl.o
 rg/fifth-avenue) compares 1911 wide-angle photographs from the New York Pu
 blic Library to 2015 Google Street View imagery. A mini-map shows each pho
 to’s location and field of view\, and a visitor to the site can “go so
 uth”\, “go north”\, or “cross the street” using the arrow keys. 
 The project came out of the [NYC Space/Time Directory](http://spacetime.ny
 pl.org)\, an initiative to communicate the history of the city using histo
 rical maps\, geodata\, and open source tools. Code: https://github.com/nyp
 l-publicdomain/fifth-avenue.\n\n2. [“1940s.NYC”](https://1940s.nyc) pl
 aces digitized photos of most buildings in the five boroughs of New York C
 ity\, collected from 1939 to 1941 by the Tax Department with help from the
  Works Progress Administration\, on a map. Zooming in loads georeferenced 
 scans of historical maps\, and clicking on a marker opens a panel displayi
 ng the historical photos. [“80s.NYC”](http://80s.nyc) remixed the site
 \, using more recent images from the Department of Finance. Code: https://
 github.com/jboolean/1940s.nyc\, https://github.com/bdon/80s.nyc.\n\n3. [
 “A Stroll Down Flatbush Avenue circa 1914”](https://stroll-down-flatbu
 sh.chriswhong.com) strings together 65 photographs\, captured approximatel
 y every 50 feet\, from the [New-York Historical Society’s “Subway cons
 truction photograph collection\, 1900-1950.”](https://digitalcollections
 .nyhistory.org/islandora/object/nyhs%3Asubway) Geometries for the photos\,
  which are often set at nearby intersections\, were manually modified\, an
 d a mini-map showing those points is navigable with the up and down keys. 
 Code: https://github.com/chriswhong/stroll-down-flatbush.\n\nThe entire su
 bway construction photograph collection contains nearly 100 times as many 
 photos as shown along Flatbush Avenue with associated latitudes and longit
 udes across New York City. What are the best practices for mapping these g
 eotagged archival photos\, with imprecise and duplicate locations\, as wel
 l as rich text metadata like titles\, topics\, dates\, and descriptions?
