Hello World + Examples

Intro to Mapview

Hands-on Lab

Import Data

Why Map + MapView?

Class: esri/Map

  • Storing, managing 2D and 3D layers
  • One map can referenced by multiple views

Constructor & Properties

  • Consistent across the API

  • All properties of a class can be set within the constructor

  • Or, directly on the Class.

  • Demo

Why Map + MapView?

Class: esri/views/MapView

  • Displays a 2D view of a Map and its elements
  • Contains a Map instance and a <DIV>

MapView Properties

  • Includes center, extent, graphics…

Demo

Using the View Programmatically

  • MapView.extent

  • MapView.scale

  • MapView.zoom

  • MapView.viewpoint

  • MapView.goTo()

 

Using the View for Navigation

  • User navigation is enabled by default

 

Demo

Create a 2D Map with a Layer

Handling View Events

Promises

someAsyncFunction().then(callback, errback);

//And we use .when() in the JS API:

someAsyncFunction().when(callback, errback);

Promises

  • Many methods in the API return promises

  • Some classes return a promise

  • Similar to an event listener…but, maintains state

  • Can be called well after initialization

Promises when

Promises Chaining

Autocasting

Long-hand approach

Autocasting

Documentation Example

Watching Properties

  • watch (property, callback)

Watcher Demo

Widgets

Class: esri/widgets/Widget

Popup Widget

  • All Views have a default group

  • Default popup can display generic content

Demo

Directions Widget

  • Wraps pre-built search and routing functionality

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 vs 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

How do I get the API

  • By using Conda
  • What is Conda?

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

If you don't have ArcGIS Pro

Install ArcGIS Package

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

Upgrade from Older  ArcGIS Package

  • Type the following into the python command prompt or command prompt
    • -conda upgrade -c esri arcgis

Offline Install

Install the API on a machine without internet access

Start Jupyter Notebook

  • Type the following into the python command prompt
    • jupyter notebook

Test the Install

from arcgis.gis import GIS
my_gis = GIS()
my_gis.map()

Building Native Apps

ArcGIS Runtime Overview

  • Esri’s developer product for native app development
    • Incorporate ArcGIS functionality into mobile and desktop applications
    • Web service client and local (offline) capabilities
    • SDKs for .NET (including Xamarin), Android, iOS, Java, Qt, and macOS

         

 

ArcGIS Runtime Overview

  • High-performance 2D and 3D mapping
  • Integration with Portal, ArcGIS Online, and ArcGIS Server
    • Load, edit, and save web maps
    • Use map, image, and feature services
    • Geoprocessing for complex custom analyses
  • Work offline with local data and functionality
    • Read local data (.mmpk, .tpk, etc)
    • Geocode and Routing
    • Geometric operations (buffer, etc)
    • Take web maps offline
    • Feature service editing and sync

Coding 101

Best Practices

Offline vs Online

Performance vs Availability

  • Offline Data and Services
    • Sideload data/geocoders/network models for highly interactive performance
    • No round-trip to a server
    • Consider hybrid online + offline if appropriate
  • Consider Network Availability & Data Qualities:
    • Do you need to edit? If not, perhaps side-loading is an option.
    • Will many people get the same data? Maybe generate once, sideload often.
    • Lots of data changing often? Try to sync when on WiFi.
    • How fast is the network in the field?
    • How consistent is the network in the field? Patchy?

Perfomance

Work on the device

  • GeometryEngine
    • Manipulate geometry on the device
    • Buffer, Union, Difference etc.
    • Projection
  • Offline Data
    • Data on the device for highly interactive performance
    • No round-trip to a server
  • Graphics Overlays
    • Dynamic Mode (smaller number of moving graphics – good interactive performance)
    • Static Mode (large number of graphics – less interactive performance)
