Chapter 9. ArcGIS API for Python and ArcGIS Online

Thischapter will introduce the ArcGIS Application Program Interface(API) for Python and ArcGIS Online. The ArcGIS API for Python is a Python library for working with maps and geospatial data. This API can be installed locally usingcondaand interacts with Esri's cloud GIS, whether that's ArcGIS Online (SaaS) or Portal for ArcGIS, a server product thatoffers on-premises cloud GIS deployment for organizations. The API offers a modern solution to scripting for web mapping with Python and works well with Jupyter Notebooks.

The following topics will be covered in this chapter:

Introducing the ArcGIS API for Python
Installing the API
Using the API with different Esri user accounts
Introducing some modules of the API
Interacting with the API's map widget
Searching and displaying vector data
Displaying and geoprocessing of raster data
Setting up a personalized account for using ArcGIS Online
Publishing and managing content in ArcGIS Online

Introducing the ArcGIS API for Python and ArcGIS Online

Esri, the geospatial software company known for its ArcGIS platform, adopted and integrated Python into their ArcGIS desktop software, as well as its successor ArcGIS Pro. The first Python site package developed by Esri was the ArcPy site package, which is a collection of Python modules that offers all existing, as well as extended, ArcMap and ArcGIS Pro functionality. Python can now be used as a scripting and programming language to automate repetitive tasks that involve a lot of interaction with the Graphical User Interface (GUI). With ArcPy, these tasks could be carried out through a Python script, add-on, or toolbox.

Python was introduced successfully with ArcGIS desktop, while GIS itself was moving into the cloud—not only geospatial data but also the software itself. Esri offered organizations the possibility to do this through a variety of cloud environment offerings, using either public, private, or hybrid cloud services. In this...

Summary

This chapter introduced the brand new ArcGIS API for Python, which is built on Python 3.5. You learned how to make use of the API, Jupyter Notebooks, and data processing with data stored in the cloud-based ArcGIS Online system. We covered how the API is organized into different modules, how to install the API, how to use the map widget, how to log in to ArcGIS Online using different user accounts, and working with vector and raster data. Using some of the API modules, we learned how to use the API for Python to perform basic geospatial analysis and to create ArcGIS Online web maps.

The next chapter will introduce Python tools for interacting with cloud-based data for search and fast data processing. In particular, it focuses on the use of Elasticsearch and MapD GPU databases, both of which are based on the AWS cloud infrastructure. The reader will learn to create cloud services for geospatial search, geolocated data processing, geolocated data, and learn how to use Python libraries...
