Repeat photography

Sometimes abbreviated RP, repeat photography is the art and science of precisely retaking historical photographs in order to document, analyze and understand change. We prioritize well-captured and reliably relocated scenes, offering opportunities to examine successional change in vegetational communities, and in some cases landform evolution.

Abandoned gold-rush town of Dyea, near Skagway. 2005 retake of 1899 photo, by Kathy Hocker and Karl Gurcke.

‘Construction’ note:

In the original 2014 version of this RP page we embedded an interactive map, hosted by ESRI’s ArcGISonline showing locations of historic photos—both ground-based (red triangles) and aerial obliques (black arrows)—Symbols pointed in direction each photo was taken. Clicking on an arrow opened a pop-up with info about the photo and a thumbnail. Clicking on that thumbnail opened a medium-resolution view.

Initially developed and supported by the Southeast Alaska GIS Library, that map portal was ‘unplugged’ in 2019. One of my goals for JuneauNature is a much expanded assortment of ‘arc-online’ windows, using ESRI’s extraordinary tools for cartography and storytelling. Sorry, for this lapse, and here’s hoping it’s only a brief one, soon to be remedied with even cooler displays.
