Quick Overview of the ArcGIS API for Python

  • A Pythonic GIS API
    • Corresponds to best practices
    • Uses standard Python constructs
    • Data structures with clean,                              readable idioms
  • Easy for a Python programmer to use ArcGIS
  • Easy for an ArcGIS user to script and              automate their GIS

ArcGIS API for Python and ArcPy

  • ArcGIS API for Python
    • Script against a portal
    • ArcGIS Online or ArcGIS Enterprise
    • Python 3.x
  • Analysis, Portal Admin, Content Creation, Big Data Analysis
  • ArcPy
    • ArcGIS Desktop
      • ArcMap - Python 2.x
      • ArcGIS Pro - 3.x
  • Mostly Geoprocessing
  • Some map automation

ArcGIS + Jupyter = 

Four Different Personas

  • Analysts and Data Scientists

  • Power Users/Developers

  • Content Publishers

  • Org Adminstrators

Introducing the GIS Module 

Your gateway to scripting a Web GIS

Install the ArcGIS API for Python

You can install the Python API with or without ArcGIS Pro

If you have Pro on your machine, Conda and Jupyter Notebook is already install for you

Install using ArcGIS Pro

Python Package Manager

How do I get the API

  • By using Conda
  • What is Conda?

If you don't have ArcGIS Pro

Install ArcGIS Package

  • Type the following into the Anaconda command prompt 
    • conda install -c esri arcgis

Start Jupyter Notebook

  • There will be an icon under the Anaconda3 (64bit) apps in Windows
