Why Map + MapView?
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?
MapView Properties
- Includes center, extent, graphics…
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
Hands-on Lab
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
Watching Properties
-
watch (property, callback)
Widgets
Class: esri/widgets/Widget
Popup Widget
-
All Views have a default group
-
Default popup can display generic content
Directions Widget
-
Wraps pre-built search and routing functionality

- Python 3.x
- Analysis, Portal Admin, Content Creation, Big Data Analysis
-
ArcPy
-
ArcGIS Desktop
- ArcMap - Python 2.x
- ArcGIS Pro - 3.x
-
ArcGIS Desktop
- Mostly Geoprocessing
- Some map automation
ArcGIS + Jupyter =
Four Different Personas

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
- You will need to install Anaconda
- https://www.continuum.io/downloads
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
Install the API on a machine without internet access
- Install the latest version of full Anaconda for Python 3x for your OS
- Download the latest version of the ArcGIS API for Python appropriate for your OS from Esri's channel on anaconda.org
- Open your terminal application and install the API
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

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)
