Revealing our Past: Using Web GIS for Dissemination of Historical Air Photos and Topographic Maps

Barbara Znamirowski, Trent University

As part of its Historical GIS (HGIS) initiatives Trent University Library’s Maps, Data and Government Information Centre is developing a Regional Environmental History Atlas. The primary goals of the project are to create a discovery tool for current and historical information, encourage research and teaching that fosters new ways of understanding our region, and encourage interdisciplinary collaboration within the university and with regional partners and members of the public.

This talk will review the project, focusing on two main components: web dissemination of historical air photography and topographic maps. It will include an overview of how we got started, key procedures, and lessons learned. Key technical (scanning, georeferencing, web development) and administrative components such as budgeting and management will be covered.

A demonstration of the project web site will show how ArcGIS for Server is being used for search and discovery and downloading of air photos and topographic maps.
The presentation will highlight functionality of the system and some of the key decisions we faced in designing a system that would respond to diverse researcher needs while meeting technical considerations such as storage and packaging of products for downloading.
