HISTORICAL GIS : Technologies, Methodologies and Scholarship
"Historical GIS: Technologies, Methodologies, and Scholarship" provides a comprehensive exploration of Geographic Information Systems (GIS) as a tool for analyzing historical data. The book delves into the integration of spatial and attribute data within a GIS framework, showcasing various techniques and methods for visualizing, querying, and analyzing historical information.
The chapters are organized systematically, covering a wide range of topics related to historical GIS:
- In the initial chapters, the book introduces the fundamental concepts of spatial data representation. It discusses spatial data types such as points, lines, and polygons, demonstrating how these elements are utilized to build complex geographical features in a GIS.
- The concept of networks is explored, highlighting the creation of networks using line segments and topological information. Raster surfaces are also introduced, illustrating how they can be used to represent continuous phenomena in a GIS environment.
- The book delves into digital terrain modeling, emphasizing the use of triangulated irregular networks for modeling terrain surfaces.
- The integration of spatial and attribute data is a core aspect of historical GIS. The book explains the principles of relational joins, demonstrating how to link spatial data to external attribute databases.
- Layer abstraction is discussed as a means of organizing complex maps, allowing users to work with different data components independently.
- The book explores digitizing techniques and geo-referencing, essential for aligning historical maps and data accurately.
- Various spatial and attribute querying techniques are covered, enabling users to retrieve specific information from historical datasets.
- Advanced topics include overlay operations, buffering, map algebra, and spatial analysis. These techniques are applied to historical data to derive meaningful insights.
- The book showcases examples of thematic mapping, demonstrating how historical data can be visualized effectively through choropleth maps, cartograms, and other representations.
- Temporal aspects of GIS are explored, focusing on the incorporation of time as an attribute and the creation of temporal GIS.
- The book addresses challenges in gazetteer construction and normalization, crucial for standardizing place names and improving data consistency.
- Advanced spatial analysis methods are discussed, including point pattern analysis, spatial statistics, and geographically weighted regression (GWR).
Throughout the book, numerous case studies and examples are presented, illustrating the application of historical GIS to real-world scenarios. The book emphasizes not only the technical aspects of using GIS in a historical context but also the scholarly implications and methodologies associated with historical research.
"Historical GIS: Technologies, Methodologies, and Scholarship" serves as an invaluable resource for researchers, historians, geographers, and GIS practitioners interested in exploring and analyzing historical data using modern GIS tools and techniques.
