Preface
Open source GIS is a rich and rapidly expanding field of endeavor. Take
a look at the FreeGIS Project website,1 and you抣l see an impressive list
of more than 300 applications. With such a wide array of software available,
it抯 impossible for any one book to cover everything. In Desktop
GIS, the goal is to introduce you to some of the major open source GIS
applications that are in active development today. It抯 a tough proposition
to cover each of these to the extent they deserve. Instead, the
approach is to introduce you to tools that will get you started with open
source GIS and enable you to reach out and expand on your own.
You might think this book is a beginner抯 book. Although it抯 true that
it starts out that way, we move quickly into areas that intermediate
and advanced users can profit from. Starting from a simple problem
and moving through the concepts of using open source, we抣l advance
to examples of real GIS analysis.
How to Use This Book
If you are new to the concept of GIS, begin at the beginning. For those of
you familiar with GIS but new to open source, the introduction is worth
reading, but you should definitely take a look at Chapter 2, Getting
Started, on page 23 for an overview of things to consider.
If you want an overview of what抯 available in open source GIS, before
you proceed take a look at Appendix A, on page 269.
Following the introductory chapters, we delve into working with data,
digitizing and creating new data, and then doing analysis using open
source GIS applications such as GRASS, QGIS, and uDig. In later chapters,
you will find information on scripting and writing your own
applications.
Since this book is not a tutorial, we won抰 go into all the nuances of each
application mentioned. We will show you how to accomplish common
tasks using the software, and in those cases you抣l find a fair bit of
guidance.
The appendixes contain information on installing and using some of
the applications mentioned in the book. If you need further assistance
getting started, refer to websites for the respective projects where you抣l
find a wealth of information.
Versions
The dynamic nature of the open source GIS community was readily
apparent during the writing of this book with several projects releasing
major versions. Fortunately, the differences between the versions don抰
significantly impact our illustrations and examples. Where there is a
difference, it is noted in the text. For software used in the examples,
the following versions were used:
GRASS
For most of the examples, version 6.2.x was used. Where the version
6.3 release candidate was used, it is noted in the text.
Quantum GIS
Most of the examples use version 0.8.1. In later chapters where
the Python bindings are discussed, version 0.9.x is used. There
are some minor differences in the user interface between 0.8.1
and 0.9.x, but you should be able to use the later version without
much difficulty.
uDig
For the uDig examples, you can use either the stable (1.0.6) version
or the current version 1.1 release candidate.
For GDAL, GMT, PROJ.4, and PostGIS, you can use the latest versions
to work through the examples in the book.
