3 Real-Time GIS

4 Real-Time GIS Integration and exploitation of streaming data Web Device Desktop Integrates real-time streaming data into ArcGIS Performs continuous processing and real-time analytics Sends updates and alerts to those who need it where they need it GeoEvent Extension ArcGIS Server

5 Real-Time GIS Web Device Desktop Stream Layer Stream Service GeoEvent Extension ArcGIS Server

6 Getting Real-Time data into Web Applications

7 Receiving Real-Time Data Easily integrate real-time streaming data into ArcGIS using an Input Connector GeoEvent Extension Inputs GeoEvent Services Outputs You can create your own connectors. Poll an ArcGIS Server for Features ActiveMQ CompassLDE Out of the Box HTTP REST WS WS Poll an external website for GeoJSON, JSON, or XML Receive Features, GeoJSON, JSON, or XML on a REST endpoint Receive GeoJSON or JSON on a WebSocket Receive RSS Receive Text from a TCP or UDP Socket Subscribe to an external WebSocket for GeoJSON or JSON Esri Gallery CAP Cursor-on-Target Exploitation Support Data GeoMessage Instagram KML Partner Gallery envirocar exactearth AIS FAA (ASDI) GNIP Networkfleet * * * OSIsoft *.csv Watch a Folder for New CSV or JSON Files Kafka * Valarm NMEA 0183 Zonar * RabbitMQ Sierra Wireless (RAP) Trimble (TAIP) Twitter

10 StreamService Intro

11 Getting Real-Time data into Web Apps Two patterns Feature layers pull from feature services - Web apps poll to get periodic updates - Must be backed by an enterprise geodatabase (EGDB) Stream layers subscribe to stream services - Web apps subscribe to immediately receive data - Low latency and high throughput ArcGIS Server feature layers Polling (Pull) Your Applications GeoEvent Extension Update a Feature Add a Feature Map Services Feature Services Stream Services EGDB Send Features to a Stream Service Feature Layer Stream Layer

12 Stream Services The foundation for real-time web apps Are discoverable via services directory - server>/arcgis/rest/services/iss-stream/streamserver Can be secured just like any other ArcGIS Server service using - ArcGIS internal user store - Active Directory/LDAP - PKI Can be scaled using clustering

13 Demo Real-Time in the Server Stream Service

14 Stream Layers Enabling real-time web apps Part of the ArcGIS API for JavaScript Subscribe to stream services - Immediately receive and render data - Configurable symbology with familiar api - Direct access to data on arrival Can filter on - an area of interest - field values Stream services communicate over a web socket - Web socket protocol must be allowed on network - Client must have a browser that supports web sockets

15 Demo Real-Time in Web Maps Stream Services

16 Stream Layer Deployment Patterns Enabling real-time web apps Configure in a Web Map and - Just share it - Web App Template - Web App Builder Custom JavaScript apps

17 Building WebApps using the ArcGIS JavaScript API

19 ArcGIS JavaScript API StreamLayer: Constructors

20 ArcGIS JavaScript API StreamLayer: Methods Add / remove a StreamLayer to / from a Map

21 ArcGIS JavaScript API StreamLayer: Event handler Subscribe to events of the StreamLayer

22 ArcGIS JavaScript API StreamLayer: Properties Set a renderer for the StreamLayer SimpleRenderer TemporalRenderer ClassBreaksRenderer UniqueValueRenderer DotDensityRenderer ScaleDependentRenderer

23 ArcGIS JavaScript API StreamLayer: Properties Set a renderer for the StreamLayer SimpleRenderer TemporalRenderer ClassBreaksRenderer UniqueValueRenderer DotDensityRenderer ScaleDependentRenderer

24 ArcGIS JavaScript API StreamLayer: Filtering Specify an attribute or spatial filter ` `

25 ArcGIS JavaScript API StreamLayer: Intercepting Events Intercepting messages received by the StreamLayer `

26 ArcGIS JavaScript API StreamLayer: Functionalities Store latest Features

27 Combining real-time with static data ArcGIS Server Stream Services GeoEvent Extension Common Join field Stream Layer Related Features EGDB

28 ArcGIS JavaScript API StreamLayer: Functionalities Use a related Features Find sample application at: tompa0003/flightdemo

29 ArcGIS JavaScript API StreamLayer: Sensor Network Demo Scale and pan dependent WebApp `

30 Summary Stream Services - enable low-latency immediate delivery of data - are discoverable, securable and scalable Stream Layers - Consume and Display streams of features - Configurable symbology - Filter by Geometry and Attribute
