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.

Fixing broken data sources with MapDocument.findAndReplaceWorkspacePaths()


The MapDocument.findAndReplaceWorkspacePaths() method is used to perform a global find and replace of workspace paths for all the layers and tables in a map document. You can also replace the paths to multiple workspace types at once.

Getting ready

We need to cover some definitions before examining the methods used to fix datasets. You'll see these terms used frequently when discussing the methods used to fix broken data sources, so you'll need to understand what they mean in this context. A workspace is simply a container for data. This can be a folder (in the case of shapefiles), personal geodatabase, file geodatabase, or ArcSDE connection. A workspace path is the system path to the workspace. In the case of file geodatabases, this would include the name of the geodatabase. A dataset is simply a feature class or table within a workspace, and finally, a data source is the combination of the workspace and dataset...
