Overview of this book

ArcGIS is an industry standard geographic information system from ESRI.This book will show you how to use the Python programming language to create geoprocessing scripts, tools, and shortcuts for the ArcGIS Desktop environment.This book will make you a more effective and efficient GIS professional by showing you how to use the Python programming language with ArcGIS Desktop to automate geoprocessing tasks, manage map documents and layers, find and fix broken data links, edit data in feature classes and tables, and much more."Programming ArcGIS 10.1 with Python Cookbook" starts by covering fundamental Python programming concepts in an ArcGIS Desktop context. Using a how-to instruction style you'll then learn how to use Python to automate common important ArcGIS geoprocessing tasks.In this book you will also cover specific ArcGIS scripting topics which will help save you time and effort when working with ArcGIS. Topics include managing map document files, automating map production and printing, finding and fixing broken data sources, creating custom geoprocessing tools, and working with feature classes and tables, among others.In "Python ArcGIS 10.1 Programming Cookbook" you'll learn how to write geoprocessing scripts using a pragmatic approach designed around an approach of accomplishing specific tasks in a Cookbook style format.

Accessing ArcPy modules with Python


Up to this point, we have covered some basic concepts related to ArcPy. In addition to the basic ArcPy site package, there are a number of modules that you can use to access specific functionality. These modules must be specifically imported into your scripts before you can use the functionality provided. In this recipe, you will learn how to import these modules.

Getting ready

In addition to providing access to tools, functions, and classes, ArcPy also provides several modules. Modules are purpose-specific Python libraries containing functions and classes. The modules include a Mapping module (arcpy.mapping), a Data Access module (arcpy.da), a Spatial Analyst module (arcpy.sa), a Geostatistical module (arcpy.ga), a Network Analyst module (arcpy.na), and a Time module (arcpy.time). To use the functions and classes included with each of these modules you must specifically import their associated libraries.
