ArcGIS 10 provides a new Python
mapping module (arcpy.mapping) that allows you to interact with the contents of
map documents and layer files without necessarily needing to interactively open an
ArcMap session. The methods, properties and functions available in this
new map scripting API enable you, for example, to automate changing data
sources, modify layer properties, export and print maps, as well as automate the
thematic maps and map series. Because the new mapping module is part of
the ArcPy geoprocessing framework, scripts can be used within ArcGIS Desktop
but can also be published to ArcGIS Server as geoprocessing services making
it much easier to make mapping and printing capabilities available on the
The following links are resources
that will help you learn more about arcpy.mapping, get access to popular
sample scripts available for download, and
links to new training resources:
A new Introduction to
arcpy.mapping help topic is a great starting point. It includes
links to a new arcpy.mapping tutorial and general guidelines for working with
arcpy.mapping. ArcGIS Desktop help has a complete section
dedicated to the ArcPy mapping module. Embedded within the help topics
are over 100 different, practical help samples that can be copied/pasted into your applications. Be
sure to review the “Best ways to get started” section.
A video presentation called Python Scripting for
Map Automation in ArcGIS 10 presented at the 2011 Developer’s Summit is an excellent way
to get started. This presentation not only introduces arcpy.mapping but
also demonstrates many of its use cases.
presentation called Arcpy.mapping: Export a map in PDF format from a web
browser that demonstrates how arcpy.mapping scripts can be published as
geoprocessing services and published to web applications.
- Approximately 20
script tools that perform routine map and layer management tasks, printing and
exporting, as well as basic cartographic operations.
This is an excellent download because it
includes many practical code samples that perform a variety of tasks and they
are easy enough to modify for your own purposes.
- A script
tool that combines Data Driven Pages, arcpy.mapping, and the ReportLab site package to generate a reference map book that includes street index
pages. It demonstrates how arcpy.mapping can be used to extend Data
Driven Pages capabilities.
- A script
that incorporates Data Driven Pages and arcpy.mapping to build a map series
that includes dynamic graphic tables. There is a very complete README.doc file
included with the download that also addresses other useful tips and tricks
that go along with the application.
Basics of Python (for ArcGIS 10).
This course teaches fundamental concepts you need to know to create
Python scripts in ArcGIS. You will learn guidelines for proper Python syntax,
techniques to troubleshoot common errors, and how to use loops to test for
conditions and execute different code based on the result.
Python Scripting for Map Automation in
ArcGIS 10. This course teaches how to automate map production and
related data management tasks that would be time-consuming and tedious to
perform manually. You will learn how to work with the mapping module of the
ArcPy site package to quickly and easily update map layers and map document
properties, modify map content, and produce individual maps and map books.
