Workshop structure and objectives
The workshop will focus on the role of digital gazetteers in georeferencing applications, starting with overviews of the state of the art and current activities, and leading to a consensus on the opportunities and directions for collaboration and the advancement of a research and practice agenda. Roughly 35 participants will be selected through a combination of open call and invitation. Ample time will be allocated to demonstrations, and to plenary and small-group discussion.
The workshop will have three focus areas
A. Components of gazetteer services
The three core elements of gazetteers – placenames, place categories, and geospatial locations – support the translation between informal georeferencing using placenames (“Santa Barbara”) and place categories (“city”) and the formal georeferencing of mathematical schemes (e.g., longitude and latitude coordinate systems). These elements plus explicit relationships between named geographic places and the identification of time frames for places and their characteristics are the fundamental components of digital gazetteers. Within the context of gazetteer services - such as support for enterprise georeferencing systems, geoparsing of text to derive spatial locations, navigation services, and support for geographic information retrieval (GIR) - the complexities of each of these components challenge the collection and use of gazetteer data. This session will explore such issues as:
B. Georeferencing as a process
Georeferencing by naming and categorizing natural and human-made geographic features is universal. The practice is highly influenced by individual strategies, local conventions, and requirements of particular applications. This session will explore studies that ferret out the nature of the motivations and practices of place naming and categorizing in individual, cultural, historical, information management, scientific, and business contexts and how they inform the construction and use of gazetteers and gazetteer services. This session will explore issues such as the following and their effect on the design of gazetteers and user interfaces to georeferencing services:
C. Interoperable gazetteer services
Gazetteer data exists in many independent sources often dissimilar in construction and content, including:
This session will explore the requirements of gazetteer protocols and services to support interoperable access to and use of these distributed sources, taking into account such issues as:
This session will also consider the steps needed to establish (1) an initial network of gazetteers as a platform for research and development, and (2) application software for the creation and maintenance of gazetteer data, including downloading, integrating, and documenting data from multiple sources.
