A project was initiated in 2003 to assess landscape changes in the Southwest Alaska Network (SWAN) of National Parks through the use of repeat photography. A total of 1099 historical photographs dating as far back as 1895 have been acquired for Lake Clark (191), Katmai (654), Aniakchak (204), and Kenai Fjords (50). A digital archive structure and ThumbsPlus-Access database have been developed to compile information about the photographs and prioritize them for repeat photography. The photographs are stored as high-resolution (~10 Mb tiff) images for archiving and research, and low-resolution (~300 kb jpg) images for rapid review and broader distribution. The primary subjects of the photographs have been categorized as glacier, coastal, floodplain, volcanism, landslide colluvium, avalanche chute, lacustrine, plant succession, shrub expansion, tree expansion, people, and human disturbance. The database allows the user to easily sort and view photographs by the desired data fields. During 2004–2006, a total of 294 photographs were repeated in three SWAN units by ABR and NPS personnel: 59 in Lake Clark; 134 in Katmai, and 101 in Aniakchak. Additionally, 254 photographs were taken of new scenes in Katmai (39) and Aniakchak (215).
