Introduction to
Geoprocessing
Scripts using Python
Overview
This course introduces the Python (®)
scripting language included with ArcGIS
and demonstrates how it can be used to
access and automate geoprocessing
functionality. Participants will learn the
Python language syntax, and then write
scripts to automate geoprocessing
operations. Participants will also learn
how to include Python scripts as custom
tools in ArcToolbox.
Audience
This course is designed for experienced
ArcGIS users who want to learn how to
automate everyday processes or those who
want to create complex analytical scripts.
Those who have used ARC Macro Language
(AMLTM) and AvenueTM to write scripts will
also find the course of interest.
Goals
Understand the basics of the Python
scripting language.
Understand how scripts can be used in
the ArcGIS geoprocessing framework.
Incorporate tools and environment
settings into scripts.
Incorporate cursors, describe objects,
and enumerations into scripts.
Add scripts to ArcToolbox.
Access resources for debugging Python
code.

Topics covered
The geoprocessing framework:
ArcToolbox; Dialogs; Models; Command
line; Scripts.
The basics of Python: Variables;
Commenting code; String concatenation;
Looping; Conditional statements;
Modules.
Accessing tools and environment settings
in scripts: The Geoprocessor ArcObject;
Accessing the Geoprocessor from Python;
Accessing tools and environment settings
from Python.
The Geoprocessor object: The
Geoprocessor Programming Model, the
Geoprocessor (GpDispatch) object.
The describe objects: Access various
properties for different data types (e.g.,
feature classes, workspaces, datasets,
raster datasets, etc.).
The enumeration objects: Create lists of
data (e.g., tables, rasters, feature classes,
workspaces, fields, feature datasets, etc.).
The cursor objects: Search cursors; Insert
cursors; Update cursors.
Incorporating scripts into the
geoprocessing framework: Scripts as tools;
Scripts in models.
Finding and fixing errors: Python error
handling; Identifying syntax and logical
errors.
Prerequisites and
recommendations
Students should have completed one of the
following or have equivalent knowledge:
Introduction to ArcGIS I, ArcGIS Desktop II:
Tools and Functionality, Learning ArcGIS
Desktop. Basic programming skills, such as
using loops and conditional statements, are
also recommended.
