Exploring Geographic Information Systems

This exploration of geographic information and geographic information systems (GIS) expands the discussion beyond the normal input-processing-output sequence. It begins by examining the manipulations that support analytical uses of GIS, including measurement and frameworks, representations, data quality, transformation and operations, parametric mapping, simple logic and overlay, taxonomy, distance transformations and surfaces. It then moves on to discuss operations that connect the practical exercises in the book to professional applications of GIS techniques in bureaucratic, social and cultural contexts.
