Most desktop mapping and GIS
applications have focused on mapping and spatial data management for viewing
and geo-query of mapped data. Map analysis and GIS
modeling involve entirely new spatial reasoning concepts and procedures that
are not reflected in our paper map legacy. This book and its companion
book, Spatial Reasoning
for Effective GIS (Berry, 1995), are based on Joe
Berry’s popular "Beyond Mapping" columns in GIS
World magazine and, discusses the new breed of map analysis tools and how they
can be used to better characterize and communicate spatial relationships.
Both books are written for GIS professionals, as well as novices, in a witty
style that entertains as well as informs.
Beyond Mapping explores the basic concepts of Geographic
Information Systems (GIS) technology and discusses the issues involved as GIS
moves from the researcher to the general user.
The emerging technology goes beyond traditional mapping and spatial data
management to new concepts and procedures for modeling the complex
interrelationships among spatial data of all kinds. Beyond Mapping is designed so the
general user can read about broad issues and then delve into more detail, even
at the algorithm level.
The book also contains an extensive resource appendix and a stimulating
discussion of “The Ten Most Beautiful Formulae in GIS,” by Nigel Waters.

Beyond Mapping: Concepts, Algorithms and
Issues in GIS
This is a collection
of Joe Berry’s popular "Beyond mapping" columns published in GeoWorld
from 1989 to 1993. In this compilation, Berry explores the concepts of geographic
information systems (GIS)
technology and discusses the issues involved as GIS
moves from the researcher to the general user. This emerging technology
goes beyond traditional mapping and spatial database management to new concepts
and procedures for modeling the complex interrelations among spatial data of
all kinds. Beyond Mapping is designed so the general user can read
about broad issues then delve into more detail, even to the algorithm level.
The material presented in Beyond Mapping is cross-referenced to
the companion GIS Concepts Digital
Slide Shows (gCON) and Tutorial Map Analysis Package (tMAP) software. The
gCON system is designed for self-learning map analysis concepts through slide
sets demonstrating GIS procedures
and applications. The tMAP software program is designed for self-learning
map analysis concepts through "hands-on" experience.
Note: The
original gCON Digital Slides Shows have been replaced by the online MapCalc
Description and Examples document and the tMAP software has been replaced
by the MapCalc Learner software (free download at www.innovativegis.com,
under “Software”).

Introduction —
There
are some similarities, but many differences, between traditional and GIS maps. This section describes the conceptual
differences and terminology used in vector and raster map formats and an
overall organizational structure for GIS
databases.
- Topic 1 Maps As Data
and Data Structure Implications — The full impact of numerical representation
of spatial data in GIS is
just beginning to be recognized. In this section the implications of
vector and raster data models on encoding, storage, and analysis are
discussed. The inherent statistical characterizations of mapped data and
their implications in map analysis are described.
- Topic 2 Measuring
Effective Distance and Connectivity — Before GIS
technology, the concept of distance was as simple and straightforward as a
ruler. Now the traditional concept of distance is first extended to
one of proximity, then to one of actual movement in geographic space,
around and through barriers. Procedures and applications of optimal
path analysis over continuous map surfaces also are presented.
- Topic 3 Roving
Windows: Assessment of Neighborhood Characteristics — The information
surrounding a point often provides insight into spatial problem solving.
Neighborhood summaries can be derived from surface configuration to
produce slope, aspect and profile maps. Or, the summaries can relate
to the context of the neighborhood for such procedures as spatial
interpolation, smoothing, and diversity analysis. More than any
other class of operations, roving windows provide entirely new
applications for map analysis.
- Topic 4 What GIS Is and Isn’t: Spatial Data Mapping,
Management, Modeling and More —
Most
initial applications of GIS
automate current cartographic practices. However, the greatest
return on investment in GIS
technology is realized through entirely new applications inspired by the
new set of map analysis tools. This section develops an awareness of
the considerations and conditions that move user perspective from computer
mapping to spatial database management to application modeling and beyond.
- Topic 5 Assessing
Variability, Shape, and Pattern of Map Features — The shape and
pattern of landscape features are readily apparent to the eye but
historically difficult to quantify. This section describes several
indices used in characterizing the configuration and arrangement of
features.
- Topic 6 Overlaying
Maps and Characterizing Error Propagation — Overlaying maps
is at the heart of most GIS
applications. However, the propagation of errors needs to be
characterized and included with the overlay results. This section
describes approaches used in establishing map uncertainty and assessing
error propagation.
- Topic 7 Overlaying
Maps and Summarizing the Results — In GIS
overlaying maps goes beyond traditional procedures of
"sandwiching" map sheets on a light-table. In this
section, procedures for point-by-point, region-wide, and map-wide overlay
summaries are described. Numerous applications and the underlying concepts
are presented.
- Topic 8 Scoping GIS: What to Consider — GIS technology is a
radical departure from traditional map processing; therefore, assessing
its potential within an organization needs to go beyond traditional
cost-benefit analysis. This section describes the major
organizational, social, and personal ramifications of implementing GIS.
- Topic 9 Slope,
Distance and Connectivity: Their Algorithms — At first
encounter, many of the advanced GIS
analytical operations are intimidating. However, a basic
understanding of the computer’s procedures is needed to assess the
potential and limitations of the new tools. This section describes
various approaches used in computing slope, effective distance, optimal
paths and visual connectivity.
- Topic 10
Cartographic and Spatial Modeling — Many GIS
applications take the technology well beyond mapping and into the larger
field of mathematical modeling. This section discusses command
"macro" construction, the mathematical implications, and the use
of GIS models in consensus
building and conflict resolution.
- Epilog — We have been
creating and using mapped for thousands of years. This section looks
at GIS’s history, current
trends and probable future.
- Appendices — Appendices are
included that describe the companion software for self-learning GIS concepts and applications, a listing of GIS resources, and a glossary of terms by
Bruce L. Kessler.

GIS book can be purchased online from Wiley.com and Amazon.com.
