ArcPy and ArcGIS - Second Edition

By: Silas Toms, Dara OBeirne

Overview of this book

ArcGIS allows for complex analyses of geographic information. The ArcPy module is used to script these ArcGIS analyses, providing a productive way to perform geo-analyses and automate map production. The second edition of the book focuses on new Python tools, such as the ArcGIS API for Python. Using Python, this book will guide you from basic Python scripting to advanced ArcPy script tools. This book starts off with setting up your Python environment for ArcGIS automation. Then you will learn how to output maps using ArcPy in MXD and update feature class in a geodatabase using arcpy and ArcGIS Online. Next, you will be introduced to ArcREST library followed by examples on querying, updating and manipulating ArcGIS Online feature services. Further, you will be enabling your scripts in the browser and directly interacting with ArcGIS Online using Jupyter notebook. Finally, you can learn ways to use of ArcPy to control ArcGIS Enterprise and explore topics on deployments, data quality assurances, data updates, version control, and editing safeguards. By the end of the book, you will be equipped with the knowledge required to create automated analysis with administration reducing the time-consuming nature of GIS.

ArcPy Geometry Objects and Cursors

The essence of geospatial analysis is using geometric shapes--points, lines, and polygons--to model the geography of real-world objects and their location-based relationships. The simple shapes and their geometric properties of location, length, and area are processed using geospatial operations to generate analysis results. It is the combination of modeled geographic data and the associated attribute information that separates geospatial information systems from all other information systems.

Until ArcPy, processing feature class geometry using geospatial operations depended on the pre-built tools within ArcToolbox. ArcPy has made it possible to directly access the geometric shapes which are stored as mathematical representations in the shape field of feature classes. Once accessed, this geometric data is loaded into ArcPy geometry objects to...
