Abstract
Historical Maps and GIS in Online Libraries
Track: Metadata and Data Publishing
Author(s): David Rumsey
David Rumsey will discuss and demonstrate his online map library, www.davidrumsey.com, as well as his use of Internet GIS to allow integration and interaction of historical maps with current geospatial data and other historical maps. Historical maps are a pictorial archive of the past, and as such they provide unique and rich data sources for GIS. Revisiting historical maps spawns new ideas and allows enhanced understanding of historic events by empowering researchers with the information to consider the spatial relationship between features. When historical maps are brought into GIS, these relationships can be quantified and compared. GIS software gives scholars the power to extract, analyze and combine the information from the maps with other spatial and attribute data, thereby enhancing interpretation of historical maps. This talk will include differences between historical mapping and GIS, the criteria for selection of historical maps to include in GIS, various aspects of georectifiying historical maps, methods of using them within Internet GIS, including vector overlays, 3D visualization, digitization of map features, and analysis of historical map data. Methods of making historical maps available to scholars, students and researchers are discussed, including potential for access through the Geography Network and other shared online GIS databases.
