As part of the Indiana GIS Atlas, the Indiana Geological Survey (IGS) has created a new interactive map to facilitate the identification and retrieval of historical aerial photographs. Named the “Indiana Historical Aerial Photo Index” (IHAPI) map, the interactive map allows users to easily locate a site of interest and determine unique identification numbers for more than 113,000 individual photos. Copies of high-resolution photos can then be ordered from various archival collections, including the IGS archive which contains about 40,000 photos. Explanatory materials and a narrated video tutorial have been created to assist users with this new Web site.
The IHAPI Map can be accessed through the following URL:
Before attempting to use the IHAPI Map, we strongly recommend that users read the instructions or watch the narrated video tutorial. Links to the instructions and the tutorial can be accessed from the Home Page of the Web site:
A presentation regarding the new IHAPI map will be made at the 2008 Indiana GIS Conference, Hyatt Regency, Indianapolis. The presentation will be on Tuesday, February 19, 3:30 PM, Regency E, Room Number 3.
Also, a Webinar, sponsored by the Indiana Geographic Information Council (IGIC), will be conducted on Thursday, April 17, 1:30-2:30 PM (http://www.in.gov/igic/class/index.html#hist).
