Building Web Apps with ImageryEmily Windahl

OverviewUsing your Imagery

• What story are you telling with your imagery?

• How can you make it as compelling as possible?

• What will the end user be able to do?

• What we’ll talk about:

- Web-enabled imagery

- Options for creating apps with imagery

- From web map to web app

From image service to web app

Image Service Web Map Web App(Imagery Layer)

Map Viewer | ArcGIS Pro

Configurable Templates

Web AppBuilder

Image services and the ArcGIS Living Atlas of the World

Web-enabled imagery

Dynamic image services (for web apps)

Server

Image Service

• How are they created?

- A raster dataset or a mosaic dataset is published using

ArcGIS Image Server (and ArcGIS Enterprise)

• Why are they useful for web apps?

- Accessible from any web-enabled device

- Allow for server-side processing using attached raster

function templates*

- Allow for client-side processing for fast, interactive

functionality

- Provide fast, dynamic display and on-the-fly rendering

*What are raster functions?

• Operations that apply processing in memory (no new files)

• They only apply processing to pixels on your screen

• As a result, processing is applied very quickly

• Can be chained together to create custom processing

templates

• Can be applied or attached to image services

ArcGIS Living Atlas of the World

• Esri-curated collection of geographic information

• Esri-produced imagery layers: ~280 results

• Image services as formatted tile layers, imagery layers, or web maps

• Includes:

- Earth observations

- Elevation

- Weather/climate data

- …and more

ArcGIS Living Atlas of the World

• Pre-configured imagery layers for:

- Landsat

- Sentinel-2

- NAIP

- MODIS

- World Elevation

the Living Atlas

Options for Imagery Apps

Why share imagery using web apps?

• Web apps…

- Add functionality, polish, and context beyond

Map Viewer

- Provide end users with basic imagery tools

- Are simple to get started, with more advanced

options for customization

- Are accessible from any web-enabled device

Configurable app templates

JavaScript API

(3.x or 4.x)

Option 1: Configurable App Templates

• Includes Story Maps and configurable templates designed for imagery

• Targeted at specific purposes

• Predetermined, limited list of configurable settings and tools

• No coding required

• Built around a configured web map

• Easy to share

- Apps are hosted on ArcGIS Online

- …or on your servers or in the cloud

Option 1: Configurable App TemplatesConfigurable apps designed for imagery

esriurl.com/ConfigApps/

• Imagery Viewer

- Visualize and interpret imagery layers

through time and space

• Image Mask

- Calculate and visualize change between two

images in an imagery layer

- Highlight an area of interest that meets a

user-defined threshold for common spectral

indices

• Image Visit

- Review the attributes of a predetermined

sequence of locations in imagery

• Also include tools for:

- Visualizing imagery layers (and non-

imagery layers)

- Searching for imagery through time

- Navigation using bookmarks

- Editing feature layers

- Measurement

- …and more

Option 1: Configurable App TemplatesConfigurable apps designed for imagery

http://esriurl.com/ImageryAppGallery

• Suite of ready-to-use configurable widgets

• Customizable themes

• No coding required

• Built around a configured web map

• Easy to share

- Apps are hosted on ArcGIS Online

- …or on your servers or in the cloud

Option 2: Web AppBuilder for ArcGIS (Core)

Option 2: Web AppBuilder for ArcGIS (Core)

• Layer List

• Legend

• Query

• Attribute Table

• Popups

• Image Measurement*

• Oblique Viewer*

* Specifically designed to work with image services

Widgets that support imagery

Option 3: Web AppBuilder, Developer EditionBuild custom widgets for imagery

• Leverage the JS API to create custom,

imagery-friendly widgets

• Extensive documentation

• Not automatically hosted through ArcGIS

Online

• …we’ve done the hard work for you.

Option 3: Web AppBuilder, Developer Edition Web AppBuilder for Image Services (WABIS) widgets

• Custom WAB widgets designed to work with

image services

• Downloadable from GitHub

• Open-source, community supported

• Requires ArcGIS Online account and WAB

Developer Edition

• Example: http://landsatexplorer.esri.com

github.com/Esri/WAB-Image-Services-Widgets

Option 4: ArcGIS API for JavaScript 3.x and 4.x

• Create custom web apps, widgets, and configurable apps

• Can be integrated with third-party frameworks (e.g. React, Angular, Ember, etc.)

• Build apps that can…

- Chart pixels

- Leverage WebGL and actual raster data for client-side processing

- Use raster functions to perform server-side processing

- Manipulate multidimensional data
