Geographical data are used in so many aspects of our lives today,
ranging from disaster relief operations through to finding
directions on our mobile phones. We can all be data collectors,
adding locational information as we capture digitally our
day-to-day experiences. Geographical Information Systems (GIS) are
the software tools that facilitate this, turning the raw data into
useful information that can help us understand our worlds better.
Principles of Geographical Information Systems presents a thorough
overview of the subject, exploring both the theoretical basis of
GIS, and their use in practice. It explains how data on the world
are converted into digital form and the analytical capabilities
used to bring understanding to a range of areas of interest and
issues. Spatial data are usually based on two, dichotomous
paradigms: exactly defined entities in space, such as land parcels
and urban structures, or the continuous variation of single
attributes, such as temperature or rainfall. The adoption of one or
the other influences how the geographical data are structured in
the GIS and the types of analysis possible. A further area of focus
in the book concerns the problems of data quality and how
statistical errors in spatial data can affect the results of
spatial modelling based on the two paradigms of space. Fuzzy logic
and continuous classification methods are presented as methods for
linking the two spatial paradigms. The book concludes with an
overview of current developments and trends in providing spatial
data to an ever-expanding global community of users. Online
